 • • •

Safety Guidelines •

Lock Out/Tag Out NOTE In the interest of operator safety and operator compliance with OSHA regulations, guidelines have been developed to perform service and maintenance on the forklift.

Before performing service and maintenance on the forklift, review the following sections in this manual for additional procedures to be followed.

•

•

•

•

•

WARNING

The battery is very heavy. Be sure to replace and tighten any battery restraints.

Failure to comply could result in an unbalance condition or the battery could slide out of the forklift causing electrical shorts or acid to spill - or it could cause the forklift to tip.

 •

WARNING

Forklift batteries give off explosive gases during use and charging.

This gas remains in the cells long after charging is complete.

Always assume the battery is emitting hydrogen and employ proper safety requirements.

Keep battery vent plugs firmly in place at all times, except when adding water or taking hydrometer readings.

Keep all flame and sparks away from battery and charging area at all times (i.e. Lit cigarettes, striking a welding arc, etc).

 •

Anytime you are doing maintenance or repair on the Landoll Bendi AC forklift, remove the key from the console, unless it must be on for investigative testing.

Disconnect the battery cable connector and install a commercially available Lock Out/Tag Out device at the battery connectors and remove the main power fuse, since it’s possible to have a duplicate key.

1. Remove the key from the console.

2. Disconnect the battery cable connectors.

3. Install Lock Out/Tag Out device at the battery connectors.

4. Remove the main power fuse.

5. Place Lock Out/Tag Out warning reminder on the steering wheel.

DANGER

CAUTION

Follow the battery manufacturer’s instructions concerning maintenance and repair.

Only qualified and experienced personnel should perform maintenance and repair on batteries.

Keep the battery clean. Foreign matter in the electrolyte will result in poor battery performance.

Use caution when changing battery connectors to ensure that the polarity is not reversed.

1-5

TABLE OF CONTENTS INTRODUCTION, SAFETY, AND SPECIFICATIONS

Charging Safety

 •

•

Shorting battery terminals can release enormous amounts of energy, causing sparks or flame, or heating nearby components to dangerous temperatures.

When the battery is charging, it releases hydrogen, a highly explosive gas which can be ignited by a spark.

 •

• • • • • • •

•

1-6

CAUTION

WARNING

Wear protective clothing, rubber apron, boots, gloves, and full-face shield when performing any maintenance on the battery.

Batteries contain sulfuric acid which can cause severe skin and eye burns.

Avoid sulfuric acid contact with eyes, skin, clothing, or the floor.

If electrolyte contacts eyes, flush immediately with clean water.

In case of contact, flush immediately and thoroughly with clean water.

If the eyes have been affected, OBTAIN MEDICAL ATTENTION IMMEDIATELY. Should electrolyte be spilled on the skin, rinse promptly with clean water and soap.

A baking soda solution (one pound to one gallon of water) will neutralize acid spilled on clothing, floor, or other surfaces.

• Apply solution until bubbling stops and rinse with clean water.

Before connecting or disconnecting batteries to the charger, make sure the charger is “OFF”. Making connections while the charger is “ON” could result in serious injury to the operator and damage could occur to the charger with sparks or electrical spikes.

 •

•

• •

CAUTION

Consult the charger manufacturer’s manual covering your charger for operation and maintenance.

Consult the label on the battery for information on cell-type, ampere-hour capacity, charge rate and normal full-charge voltage.

TABLE OF CONTENTS INTRODUCTION, SAFETY, AND SPECIFICATIONS

Hydraulic System

 • •

•

•

WARNING

Make sure all hydraulic lines are tight before starting the system.

High pressure fluids are dangerous. Leaks in the hydraulic system can pierce the skin and cause severe injury.

Any fluid injected into the skin under high pressure should be considered a medical emergency despite a normal appearance of the skin. Medical attention should be administered immediately.

Relieve all pressure from the hydraulic system before attempting to service it.

T

IMPORTANT Before performing maintenance on the hydraulic system, relieve system pressure by: • Moving the forklift to a level area.

• Eliminating any load on the forks.

• Lowering the mast completely or place blocks under the mast if it is the part being serviced.

• Relieve any excess system pressure by moving the steering wheel in both directions.

• Use a jack or hoist with a 32,000 lb. (16 ton) minimum lift capacity.

• Set the forklift on designated hardwood blocks.

See Figure 1-3. Blocks are required on each of the four corners of the forklift to provide a safe and stable repair position.

Tilt Cylinder Repair



WARNING

DO NOT place feet or hands in any area through the mast or in the forklift pinch points. Servicing the tilt cylinders requires the use of an overhead hoist, hoist slings and wheel blocks. The overhead hoist and slings must have a rating appropriately greater for the weight of the mast being serviced. DO NOT work under or around a forklift that is not properly secured.

For more information refer to “Removing the Tilt Cylinder” on page 5-5.

TABLE OF CONTENTS

Inspections Inspection Introduction Inspections and preventative maintenance are an essential part of maintaining all industrial equipment. A well planned inspection program is essential to operator safety and forklift longevity.

The inspection program recommended by Landoll Company, LLC periodically checks the integrity of Bendi AC forklift systems, e.g., checking operator’s functions, fluid levels, and overall conditions.

• Checking performance of operator functions (lift, tilt, side shift, attachment, and traction systems).

• Checking for leaks.

• Checking fluid levels.

• Making sure components are securely attached.

• Checking the tires.

Preventative maintenance is the responsibility of both the daily operator and the forklift technician.

To make sure these and other systems are checked periodically, Landoll Company, LLC has developed a system of checklists. A blank copy of each checklist can be found on pages 2-2 through 2-6.

These checklists include: • Operator’s Daily Checklist • 1st 50 Hour Inspection Checklist • 500 Hour Inspection Checklist • 1000 Hour Inspection Checklist • 2000 Hour Inspection Checklist • 4500 Hour Inspection Checklist Except for the Operator’s Daily Checklist, these tasks are usually performed by a service and maintenance facility that is approved by Landoll Company, LLC. These inspection sheets should be copied, completed and maintained by the forklift technicians.

IMPORTANT The performance of the Landoll Bendi AC is dependent on the condition of the battery installed in the forklift. To ensure a long battery life and dependable forklift performance, perform the daily inspection of battery electrolyte and follow the service recommendations of the battery’s supplier.

Initial Inspection Before shipping from the Landoll Company, LLC, each Bendi AC forklift is inspected to make sure the forklift received is in impeccable condition and equipped per order. However, we recommend that: • The forklift be inspected for any signs of physical damage during shipment. Note any apparent damage on the bill of lading, and request the delivery agent to sign it. Report the damage to the distributor and the shipping company.

• Verify that the forklift configuration and options match the purchase order. Report any discrepancies to the Landoll distributor.

Items Furnished with the Forklift Standard Bendi AC forklifts are shipped from the factory with one copy each of the Operator’s Manual and Inspection Check Sheets, a battery disconnect handle, and a set of ignition keys attached to the steering column.

Items Required When the forklift is received, a battery approved for use in the forklift must be installed. The battery must be replenished from a battery charger at certain intervals.

No additional items are required to operate the forklift.

IMPORTANT Recommended service inspections are based on normal operating conditions. If the forklift is subjected to severe or above normal operating conditions, extreme temperatures, excessive dust or wet environments, or if the forklift is around corrosive materials, service must be performed at more frequent intervals.

Tools and Test Equipment In general, no special tools or test equipment beyond those found in a well-equipped service center are required for general maintenance. However, custom bearing and seal installation tools and a calibrated torque wrench are helpful when performing more involved service.

2-1

TABLE OF CONTENTS INSPECTIONS

To Prepare the Forklift 1. Check the hydraulic oil level. Completely lower the mast. Remove the left floorboard plate. Pull out the dipstick and ensure the oil level reads between the marks.

2. Check fluid level in the brake master cylinder reservoir. The Master Cylinder reservoir is located under the floor plates just below the brake pedal assembly. Remove the bolt on the lid and check the levels as indicated. The reservoir is full when the oil level is at the fill line.

3. Check the condition of the battery. The forklift battery contains concentrated sulfuric acid, which can cause severe chemical burns. When the battery is charging, it releases hydrogen. Hydrogen is a highly explosive gas, which can be ignited by a spark.

Shorting battery terminals can release enormous amounts of every, causing sparks, flames, or heating nearby components to dangerous temperatures. The battery is also very heavy. If restraints are not replaced after maintenance, the battery could slide out of the forklift tip.



WARNING

• Always disconnect the battery before performing any forklift maintenance and be sure to wear protective clothing and safety glasses when working with battery acid or the battery in general.

• Neutralize acid spills immediately with Bicarbonate of Soda.

• If acid contacts the skin or eyes, wash with water immediately and seek medical help at once.

• Always assume the battery is emitting hydrogen and employ proper safety requirements.

• DO NOT smoke, use an open flame, or create arcs or sparks near the battery.

• Consult the label on the battery for information on cell-type, ampere-hour capacity, charge rate and normal full-charge voltage.

• Packaged with every battery are specific instructions for battery safety, care and use, and a Material Safety Data Sheet (MSDS).

Read these documents thoroughly before performing any service to the battery.

2-2



DANGER

• Keep vent plugs in place and clean at all times.

• NEVER place a tool or any metal object on top of the battery where it could possibly touch battery terminals causing a short or serious electrical shock.

• Use caution when changing battery connectors to ensure that the polarity is not reversed.

• When replacing the battery, the forklift must be equipped with a battery as specified on the rating nameplate.

• Failure to comply could result in an unbalanced condition, resulting in tipping the forklift and possible personal injury or loss of life.

• Be sure to replace and re-tighten any battery restraints which have been installed on the forklift.

If the forklift has been shipped with batteries installed, first remove the batteries from the forklift. If the batteries have been shipped with electrolyte installed, check the specific gravity of the electrolyte using a hydrometer to determine if a charge is needed.

Daily Inspection Checklist The following pages are OSHA (Occupational Safety and Health Administration) required check sheets. These sheets should be copied and the copies used for maintenance checks on your Bendi AC forklift. It is the operator’s duty to inspect the lift before each shift and report all problems to the person in charge of forklift maintenance. Have a qualified mechanic correct all noted problems.

Daily pre-shift inspection is an OSHA requirement, regulation 1910.178(q)(7). Report any defect immediately to your supervisor.

The daily inspection includes: • Visual inspection of the entire forklift for any defect.

• Visual check for any hydraulic leaks.

Check that all controls and gages work properly.

Check that the Operator’s Manual is with the forklift and in good condition. If the operator’s manual is missing on your forklift, replace immediately by calling Landoll Company, LLC at 800-423-4320 or ordering on-line at companystore.landoll.com.

Data Plate

Figure 2-1: Tire wear and Damage

The data plate should be checked to verify capacity ratings and lift heights. Also check the serial number of the forklift and mast to make sure they match up with the corresponding numbers on the data plate.

Wheels and Tires For more information on tire inspection see “Tire Inspection” on page 5-7 The condition of the tires are to be checked along with the accessible lug nuts torqued at the beginning of each shift.

The forklift is equipped with tires of a size and hardness that provide the necessary traction and still maintain a proper shape to minimize tipping. To maintain stability and maximum reliability, tires must always be replaced with the type originally supplied, as listed on the specification sheet at the end of this manual. It is also recommended to replace worn tires in pairs. Drive tires with tread must be replaced when the tread depth is less than 1/16” (1.6mm) at the deepest point.



CAUTION

If tires have excessive wear and/or chunking or lug nuts are missing, repair and/or have service replace immediately. DO NOT use the forklift.

1. Inspect the tire for chunking or embedded objects.

This is caused by running over objects on a littered floor, overloading, or bad driving habits - sharp, rapid turns at high speeds or rapid starts and stops.

• Remove any embedded foreign material and torn pieces of tread as soon as it is noticed.

• Replace chunked tires if they produce a rough bouncy ride.

2-4

Check for Damage -Remove Nails, Glass, Rocks and Other Foreign Objects

2. Inspect tires for undercutting and uneven wear.

Undercutting is caused by continuous overloads, rapid sharp turns, operating on slopes, loose spindles, transporting loads with a high center of gravity, or transporting off center loads. This causes the rubber to bulge out over the edge of the steel band, cutting the rubber just above the base band.

Uneven tire wear is usually the result of mechanical defects, such as badly adjusted brakes, misaligned wheels, or a faulty drive axle.

3. Check that the tires remain centered on the wheels to prevent splitting of the base band and tread separation. Correct defects as soon as possible.

4. Flat spotting can occur from excessive heat, a load left on the forks overnight, or locking the brakes with excessive skidding.

5. Avoid oil, grease, gasoline, and acid.

6. Torque drive wheel lug nuts to 225ft. lbs. (305 Nm.) and make sure no lug nuts are missing.

Continued operation with damaged tires may result in failure of other components. This is considered abuse and is not covered under warranty.

ESD Straps Two ESD Straps are installed just behind the front axle.

These straps will drain all static electricity build-up that may occur on the Bendi AC forklift. ESD Straps should be in fair condition, bolted securely to the body and touching the ground.

F-857-0119

TABLE OF CONTENTS INSPECTIONS



• DO NOT service carriage forks while the key switch is “ON”. If a control lever is accidentally moved, serious injury could occur.

• Use only Landoll approved replacement parts. Use only quality forks that are forged or have an up-set heel and the same capacity rating as the factory installed forks.

• NEVER use forks repaired by welding.

• Always replace both forks. Switching forks from one forklift to another can be dangerous if the capacity of the forks is not known.

Figure 2-2: ESD Strap

Parking Brake The parking (hand) brake is located to the right of the steering column, ahead of the control levers.

Operation- Pull the parking (hand) brake towards the back of the forklift to set it. Push it away to release it. The forklift cannot be driven while the parking (hand) brake is engaged. The forklift will not respond to the accelerator pedal unless the parking (hand) brake is pushed forward all the way.

NOTE This test will cause the drive wheel to lock. DO NOT test the parking brake at high speed. Check parking brake at creep speed only.

Service Brakes With the key switch set to “ON”, drive forward slowly and then steadily apply the brake pedal. The forklift should stop smoothly without noticeable side pull or vibration. If any problems are detected, remove the forklift from service immediately until it is repaired.

Check the Brake Fluid Level The Master Cylinder reservoir is located under the left floor plates attached to the brake pedal assembly.

Remove the screw on the lid and check the levels as indicated. The reservoir is full when the fluid level is at the fill line.

Forks Check the forks for cracks, inspecting closely the heel portion of the forks. If any cracks are found replace the fork. NEVER attempt to repair, weld, or alter a fork.

CAUTION

Mast Racking With the key switch turned “ON”, tilt the unloaded mast rearward. The mast should stop when the tilt cylinders bottom with no evidence of mast twist (racking). If twisting occurs, adjust the tilt cylinder rods.

Hydraulic Oil z

NOTE If the forklift has been in operation, let the forklift sit for several minutes before checking the oil level to allow time for the oil to return to the tank. Completely lower the mast. Lift floor mat and remove left floor plate and pull out the dipstick to ensure the oil level reads between the marks. Add recommended oil if the level is low. See page 1-10.

Hydraulic Cylinders, Hoses, and Fittings Check underneath the forklift for evidence of fluid leaks.

Look for hydraulic hose wear, damage and leaks. Make sure clamps and fittings are tight. In the event that leaks are detected, immediate corrective action must be taken.

DO NOT operate the forklift until repairs are made and the hydraulic fluid level has been checked.

Battery Before performing any inspections or maintenance on the battery read “Battery Safety” on page 1-5.

For more information refer to “Battery” on page 5-1.

It is important to properly maintain the battery to ensure long life, strong voltage potential, and safety of the battery.

TABLE OF CONTENTS INSPECTIONS

Good Battery Care Recommendations: • • • • • • • • •

Specific Gravity Correction

Add approved water only - NEVER add acid.

Keep electrolyte levels proper.

Keep battery top clean and dry.

Keep flame and metal away from the battery top.

Keep vent caps tightened.

Avoid charging/operating battery above 115°F. Use only approved, correct voltage/current, chargers.

Keep battery cover open when charging.

If in doubt, call your local Landoll service technician.

Using a Hydrometer As the battery discharges, the specific gravity of the electrolyte reduces. A hydrometer allows you to check specific gravity of the cells, thus the charge state of the battery.

1. Remove a cap from one or two of the cells. Gently squeeze (compress) the bulb of the hydrometer.

2. Insert the tube of the hydrometer into the cell electrolyte. Slowly release the bulb to allow fluid to draw into the hydrometer. Enough fluid must enter the hydrometer to allow the float to move freely.

3. The specific gravity of the electrolyte is read off the scale of the float where it emerges from the fluid. It is a good practice to select many different and multiple cells.

4. When returning the electrolyte to the battery, ensure that the fluid is returned to the cell it was taken from and be very careful not to splash the electrolyte.

Battery Restraint System On models with th roll-out battery tray installed, the battery restraint should be in place at all times when a battery is installed in the forklift. A switch that detects the battery restraint will disable the forklift if the restraint is not in place.

Operator Controls In order to test many of the operator controls the forklift must be running. When powering on the forklift be sure to investigate any unusual noises and record them on the Operator’s Daily Checklist.

Dash Display Ensure that the Battery Discharge Indicator, Direction Indicators, Hour Meter and other readouts are functioning properly.

Steering

S.G = 1.280 BATTERY IN CHARGED STATE

S.G = 1.280 BATTERY IN DISCHARGED STATE

Before operating the forklift, check the steering system to make sure it operates correctly. To check the steering system: 1. Get in the operator’s compartment and turn the key switch to the “ON” position.

Figure 2-3: Using a Hydrometer 2-6

F-857-0119

TABLE OF CONTENTS INSPECTIONS 2. While applying the service brake, release the parking brake and set the direction control lever to “FORWARD” or “REVERSE”. The hydraulic pump motor should start running.

3. If the motor does not start, first check that the parking brake is released.

4. While moving forward or backward slowly (to avoid flat-spotting), verify that the forklift turns left and right with a relatively smooth, easy motion.

5. While moving forward or backward slowly, turn the steering wheel completely to the right (a full right-hand turn).

6. While moving slowly in either direction, turn the steering wheel completely to the left (counterclockwise) while counting the number of full revolutions. The steering wheel must complete approximately 7-9 revolutions, lock-to-lock.

7. Next, turn the steering wheel completely to the right (clockwise) while counting the number of revolutions.

The steering wheel must complete approximately 7-9 revolutions, ±1/2 revolution, lock-to-lock.

8. Sit in the forklift without touching the steering, set the direction switch to neutral, and check that the pump turns off.

Accelerator With the key switch set to “ON”, gradually push on the accelerator. The further pressed, the faster the forklift will operate. Let up on the accelerator and the forklift should come to a controlled stop. Check to make sure the control does not stick or catch. If any problems are detected, remove the forklift from service immediately until it is repaired.

Emergency STOP Press this button to shut down the drive and all mast movement. The forklift drifts to a STOP. Immediately set the parking brake.

To continue, pull out on the button to reset the switch.



WARNING

NEVER place head, hands, arms, or feet in the mast area! Make sure there is sufficient room above the forklift to raise the mast safely.

When the lift carriage reaches the top of the inner rails, the secondary cylinders and middle rails begin lifting.

Check to make sure the rails travel smoothly and that there is no chatter or visible binding.

• With the mast fully extended, begin lowering the mast. The secondary cylinders and middle rails fully lower first, followed by the primary cylinder and the lift carriage. Check for smooth travel with no chattering or visible binding.

• If there is noticeable chatter or binding, immediately notify the supervisor or service personnel.

• DO NOT attempt to operate the forklift until the problem is repaired.

Tilt Control Move the tilt lever forward and aft, tilting the mast to both extents, watching for racking.

Racking occurs when the tilt cylinder strokes are uneven.

(One cylinder bottoms before the other).

The mast rails then twist, eventually causing them to crack and separate. Proper tilt degree adjust is 5° forward and 8° backward maximum.

On taller masts the amount of tilt is restricted to: • Up to 293” mast - 3° forward and 3° backward maximum.

• Mast with a height greater than 294” - 1° forward and 2° backward maximum.



CAUTION

If this problem is left uncorrected, serious damage to the mast assembly or the tilt cylinders can occur, causing the need for extensive repair and downtime.

Lift/Lower Control With the key switch turned “ON”, raise the mast. The hydraulic motor should start running as soon as the control is moved out of the neutral position and stop as soon as the control returns to the neutral position, except when lowering. The motor shouldn't run at all when lowering the mast, unless steering is active.

Check that the primary mast cylinder extends fully and that the lift carriage rises to the top of the inner rails before the secondary cylinders begin to move.

1. To check for racking, find a reasonably level floor area to park the forklift on and center the mast on the forklift.

2. Raise the mast about 36” (914 mm) from the floor and tilt the mast full forward and rearward several times watching for twisting at the ends of the stroke.

3. If there is any twisting or racking, both tilt cylinder rods must be readjusted. Remove the forklift from service immediately and repair.

2-7

TABLE OF CONTENTS INSPECTIONS

Side-Shift Control At least once every working shift, the side shifting mechanism must be inspected for visible damage and defects. Any changes occurring with the mechanism or its workings must be reported immediately to the supervisor.

Moving parts of the side shifting mechanism entail the danger of pinching, crushing, or snagging. Safe distance must be maintained at all times to prevent clothing or body parts from being caught by the moving parts.

When side shifting, closely watch the load and forks throughout the entire operation to prevent over shift or snagging the load on other objects.

Operate the side shift only when the load is lifted off the ground.

Direction Control Check the direction control switch in both positions.

• When the direction control switch is pushed forward and the accelerator pressed the forklift should move forward.

• When the direction control switch is pushed backwards and the accelerator is pressed the forklift should move backwards.

Seat Seat Switch The driver’s seat limit switch system includes an interlock that shuts down the drive and pump motors and disables the direction control (resets to NEUTRAL) bringing the forklift to a smooth “STOP”. The mast functions remain operable.

The seat switch and actuator are located internally, between the seat cushion and the bottom plate.

To check the seat switch: 1. Sit in the driver’s seat, set the key switch to “ON” and release the parking brake.

4. Set the control lever to “FORWARD” and slowly increase motor speed until the forklift begins to move.

5. Have operator lift from the seat far enough to release the seat switch. The forklift must immediately slow to a “STOP”, and steering is disabled.

6. If the forklift continued moving forward, it must be removed from operation and the seat switch must be replaced. Refer to “Replacing the Seat Switch and Cable” on page 5-40

Speed Switch Test to ensure that the fast and slow speed settings change the maximum speed of the forklift.

Return To Neutral When you move the direction control the forklift will shift to neutral. When this switch happens the forklift should slow to a stop.

Horn SEAT SWITCH AND CABLE

Press the horn button on the front side of the directional control lever. Make certain the horn sounds when button is actuated.

Lights and Alarm Check lights for proper on/off operation. Check that alarms sound when intended. Repair and/or replace as needed.

DANGER

Failure to follow these guidelines can cause serious injury or death: • NEVER perform maintenance or service procedures unless specifically indicated in this manual or at the specific request of supervisory personnel. All other service and maintenance on your Bendi AC forklift must be provided by a facility authorized by Landoll Company, LLC to perform these services.

• Wipe up any spills immediately to prevent slipping, fire, explosion, or contact with hazardous materials.

• Failure to use lifting equipment of adequate capacity to lift and move your Bendi AC forklift can cause lifting equipment failure.

• Removing the counterweights or uprights will change the center of gravity of the forklift.

This can cause the forklift to tip. The battery is considered part of the forklift’s counterweight.

To help avoid fire related injuries: • Have fire extinguishing equipment present in the work area.

• DO NOT allow sparks or open flames while checking fluid level, leaking oil, or electrolyte.

• DO NOT use fuel or flammable cleaning fluids to clean parts.

When assembling two parts, start all of the fasteners first, then tighten them evenly and in a staggered manner. Be sure both mating surfaces are aligned, not crooked or off-center.

Observe standard torque ratings for the size and type of fastener as listed starting in “Torque Specifications” on page 1-10.

Be sure to use the proper nuts, bolts, and other fasteners as rated, e.g., SAE Grade 5, SAE Grade 8, ISO Prop Class 8.8, etc.

All fasteners must be replaced with the identical type.

Use only Landoll approved replacement parts.

Cleaning and Inspecting the Forklift Landoll Company, LLC strongly discourages the use of power washers for cleaning forklifts. The high pressure water and soap can damage components such as electrical boards, circuitry and wiring. Water and other cleaning residue promotes the formation of rust and corrosion or may otherwise degrade some forklift components. The recommended method for dust removal is compressed air. For localized cleaning, the preferred method of cleaning is the use of a non-flammable solvent.

Carefully review manufacturer provided WARNING labels and MSDS information when using solvents or other chemicals. Follow the recommended precautions regarding use of personal protective equipment and adequate ventilation to avoid breathing toxic fumes. Adhere to the manufacturer’s instructions regarding safe use and proper disposal methods.

Before using any solvent or cleaning solution, be sure that it will not damage the part you are cleaning. For example, gasoline should NEVER be used to clean parts.

Gasoline is highly flammable and may damage some types of rubber and plastic. Hydraulic brake fluid (standard, not silicone type) is often used to clean rubber parts. It also removes paint quickly, so care should be exercised when it is used.

• Clean metal parts with a de-greasing type solvent cleaner and wipe dry with a clean rag.

• Allow parts to air dry.

• DO NOT allow cleaning solvent to come in contact with rubber parts or rubber insulation, such as electrical wiring, seals, etc. to avoid corrosion.

• For non-metal parts, clean using a mild soap solution, shop vacuum for dust and loose dirt, or a dust pan and brush.

Inspection and/or Maintenance • • • •

• • •

Inspect the forklift in an area that has sufficient clearance to check all operator functions.

Lower forks to the ground and tilt mast forward.

Use wheel chocks or other positive positioning devices if drive functions will not be checked.

Raise the drive wheels so they are not in contact with the floor when checking operator functions while leaving the forklift in a stationary position.

Block the mast to prevent it from engaging.

Use adequately rated hoisted equipment if the forklift will be hoisted for service.

NEVER remove counterweights or uprights. This will change the center of gravity and can cause an unstable condition.

Performance Testing



CAUTION

Before leaving the forklift make sure that: • The parked forklift will not cause an obstruction or safety hazard and is clear of the path of fire exits/equipment.

• The forklift will not be left unattended on an incline.

• Make sure all accessories are off before continuing.

If the forklift is inoperative and you must leave it parked on an incline, securely block all wheels and remove the key.

1. The operator should be properly seated in the operator’s seat before beginning testing procedures.

TABLE OF CONTENTS SCHEDULED MAINTENANCE 2. Turn the key switch to the “ON” position.

3. Set direction switch to the “FORWARD” position.

4. Check functions described in the Operator’s Daily Checklist or other Checklists.

1st 100 Hours or 2 Week Checklist Mast Chains The chain must be adjusted so each strand is under equal tension for proper load distribution and mast operation. To determine whether the chains are properly adjusted: 1. Remove load from forks.

2. Raise the mast to put the chains under tension.

3. Press the center of a strand of chain with your thumb, then press at the same place on the other chain of the pair.

4. Each chain in a pair should have equal “give”. If tension is not equal, adjust them as described in the manufacturer’s mast service manual.

Measuring Chain Stretch If the chains stretch beyond the recommended amount, they should be replaced in pairs. Chain stretch can be measured with a chain wear scale. See Figure 3-1. The scale indicates whether the distance between two chain links is within tolerance. The shaded area in the illustration compares a stretched chain to a new chain.

Measure the chains according to the instructions printed on the chain wear scale, without load on the carriage.

• To check the free lift chains, raise the carriage 1ft.

(30 cm) off the ground to put tension on the chains.

• To check the main lift chains, raise the mast until the inner upright starts to extend putting tension on the chains.

Check Primary Lift Chain 1. Park the forklift on a flat, level surface.

2. Set the mast in the center of the forklift, facing straight ahead, level to the floor and empty (unloaded).

3. Set the key switch to “OFF”, remove the key and place the key in a secure area.

4. Measure the distance from the floor to the bottom heel of each fork tine. Measurement must be 1/8” (3.175 mm) minimum to 1/4” (6.35 mm) maximum. If it is not within 1/8” to 1/4” (3.175 mm to 6.35 mm), adjust the primary lift chain accordingly.

Chain Wear Scale Comparison Between Chains New Chain

Stretched Chain

Figure 3-1: Measuring Chain Stretch

Check Lift Operation 1. Check the lift cylinders to ensure proper sequencing.

If adjustment is needed. “Check Primary Lift Chain” or “Lift Technologies Mast Service Manual” on page 7-1.

2. Check to see that an unloaded mast will completely lift to full lift height (the relief opens). If it will not, check the hydraulic oil level in the reservoir and add oil if necessary.

3. Load the mast and raise it approximately to 5’ (1.524 m), then quickly lower the mast until it is about 6” (152.4 mm) above the floor and stop the mast abruptly.

4. Make sure the elevating channel rollers maintain proper contact with the mast channel.

5. Look for signs of galling where the rollers contact the rail. See Figure 3-4. Galling is indicated by track marks in the rails that are 1/4” to 1/2” (6.35 mm to 12.7 mm) wide running up the rail. Normal track marks are no more than 1/4” (6.35 mm) wide.

6. If galling is detected, adjust the rollers for the proper clearance over the full length of the mast rails. See Chapter 5 for reference.

Steering

General Mast Inspection

The steering knob should be oiled using a light weight oil.

See Figure 3-6. Inspect the rotation stops for wear and cracks and replace if necessary. Re-torque the stops.

Perform the following general mast inspections: 1. Check the lift cylinder for proper sequencing.

“Lift/Lower Control” on page 2-7..

2. Check if the unloaded mast elevates to full lift (relief should open). If mast will not go to full lift, check the hydraulic fluid level in the reservoir and add fluid if required.

3. With load on forks in front carry position, elevate to approximately 5 feet (1.524 m). Lower fast to within 6 inches (152.4 mm) of floor and stop abruptly. The mast should stop with a solid effect, if the forks rebound, bleed the hydraulic cylinder.

4. Check the carriage rollers and elevating channel rollers for proper contact with mating surface.

5. Look for signs of galling where the rollers contact the rail. See Figure 3-4.

• Galling is indicated by track marks in the rails that are 1/4” to 1/2” (6.35 mm to 12.7 mm) wide running up the rail. Normal track marks are no more than 1/4” (6.35 mm) wide.

6. If galling is detected, adjust the rollers for the proper clearance over the full length of the mast rails.

7. Check for proper lift chain adjustments.

8. Check for chain contact with retaining lip on sheaves.

Brakes Service Brakes The service brakes are hydraulically-actuated, disc brakes, similar to an automotive disc brake system. They are installed to the gear box / motor assembly, on the rear wheels only.

The brakes should be checked every 500 hours of operation. Normal brake pad life is determined by driving conditions.

New brake pads are approximately 0.265” (6.7 mm) thick; replace them when the pad thickness is 0.0625” (1.588 mm) or less at the thinnest point.

A few indications of possible brake pad replacement are: • Excess travel of the service brake pedal • The forklift pulling to one side when the brakes are applied • Squealing when you apply the brakes Drive the forklift at creep speed and apply brakes lightly to determine if brakes pads are contacting the disc (rotor). You should feel a slight pulsating effect as the pads contact the disc.

Parking Brake The parking brake operation should be checked.

“Parking Brake” on page 2-5.. The parking brake pad wear is also to be checked every 500 hours.

Galling

Wheels and Tires The wheels and tires should be checked for debris and the lug nuts re-torqued. “Wheels and Tires” on page 2-4.. The wheel bearings should also be repacked at this time. The disassembly and inspection procedure is detailed in “Disassembling and Inspecting Wheel Bearings” on page 5-38.

Motors and Gearboxes Drive and pump motor studs and bolts should be re-torqued. Cooling vents on the motors should be cleaned out. The hydraulic pump and gearboxes should be inspected for leaks.

Figure 3-4: Channel Galling 9. Measure the distance from the floor to the bottom heel of each fork tine. See Figure 3-5. This measurement must be 1/8” (3.175 mm) minimum to 1/4” (6.35 mm) maximum.

10. If it is not within 1/8” to 1/4” (3.175 mm to 6.35 mm), adjust the primary lift chain accordingly.

3-7

TABLE OF CONTENTS SCHEDULED MAINTENANCE 11. Visually inspect the chains for cracks, stretched or stressed links and broken pins.

12. When raising the mast, listen for usual chain noise and watch the action of the chain for anything unusual.

13. Watch for unusual pulley movement or pulley wobble that would indicate a worn mast bearing.

Major Structural Points



CAUTION

Immediately pull forklift from service and repair if frame cracks are found.

Rust Or Corrosion Check the forklift frame, side panels, floor panels as well as mast assemblies for rust and corrosion. Clean rusty or corroded areas and repaint, if applicable. Apply a thin coat of oil to any bare metal surface.

Troubleshooting Preliminary Procedures

Troubleshooting Charts

Before performing any maintenance or repair to any part of the forklift read “Before You Begin” on page 1-1.

• Thoroughly review the problem with the operator to obtain a complete description of what is wrong.

• Observe the operator’s driving practices and operating procedures to see if operator error could be the problem.

• If you suspect operator error: Review the operating procedures, and/or have the operator read the Operator’s Manual (P/N F-648) provided with each forklift.

• If the problem is determined to be operator error, return the forklift to service and see that the operator is properly retrained before being allowed to drive the forklift.

• Check the planned maintenance log to make sure that the log is up-to-date and the problem is recorded. If it is not, or if there is no log, begin one and start by performing a planned maintenance inspection of the forklift. See the Operator’s Manual or see the “Daily Inspection Checklist” on page 2-2.

• After the problem has been corrected, operate the forklift again to verify the repair and to ensure there are no additional problems. If no other problems exist, return the forklift to operation. If other problems are found, troubleshoot and repair them before returning the forklift to operation.

This chapter contains troubleshooting procedures to help diagnose and resolve problems. Once the problem is identified, refer to the referenced section for repair instructions.

Corrective Maintenance Corrective Maintenance This section is divided by features. For each feature, major adjustment and/or settings, mechanical repairs, and electrical control system repairs are addressed.

NOTE As a Safety Reminder, Duplicate Safety Information and Precautions from Chapter 1 will be shown.

It is important to always locate the section which pertains to your needs, then read the entire procedure before attempting to adjust, repair, and/or replace parts.



WARNING

• Damage to personnel and the forklift will result if service work is attempted without proper qualified experience.

• It is recommended to always use Landoll replacement parts when performing any forklift maintenance.

• Failure to use correct replacement parts may result in a failure which may cause serious injury or death.



WARNING

Disconnect the battery. NEVER place a tool or any metal object on top of the battery where it could possibly touch battery terminals causing a short or serious electrical shock.



CAUTION

To be certain the forklift will not move, place wedges, e.g., or blocks of wood at the front and back of the tires. When servicing the brakes or tires, place the block at the front and rear of the tire farthest away from the one being serviced, i.e., the tire on the opposite side of the forklift and at the opposite end.

• Set the key switch to the “OFF” position and remove the key from the console.

• Set the direction control lever to NEUTRAL and set the parking brake.

• Read and follow the safety and standards information in chapter 1. (SEE PAGE 1-1)

Battery Replacing the Battery Before beginning see “Battery Safety” on page 1-5.

Replacing the battery requires lift and support apparatus capable of supporting the weight and size of the battery.

Check the data plate for battery information. See Figure 1-1.

An external battery roller tray stand is also helpful, and available through a Landoll distributor, to allow the battery to be pushed into the compartment.

To Replace a Battery: 1. Return the forklift to service charging station area.

2. Set the key switch to “OFF” and remove key from easy access.

3. Place blocks in front of and behind all wheels.

4. Unlatch the compartment cover (below drivers seat) and raise the battery compartment top cover.

5. Secure the cover to the overhead guard latch and insert the locking pin. Jiggle cover to be sure latch is secured. See Figure 5-1.

6. Open the right side door by sliding the locking lever to the right, then swing the door fully opened.

7. Disconnect the battery/forklift cable disconnect and lay the battery cable across the battery top.

• Be sure to use the proper nuts, bolts, and other fasteners. Many are specifically rated: SAE Grade 5, SAE Grade 8, ISO Prop Class 8.8, etc. must be replaced with the identical type.

• Whenever possible, return the forklift to a service area having sufficient lighting, work space and an assortment of tools needed to complete the repair.

TABLE OF CONTENTS CORRECTIVE MAINTENANCE

Charging a Wet Cell Battery “Charging Safety” on page 1-6 1. Remove each vent cap and check electrolyte levels.

Ambient temperature should be +77° F (+25° C) to get a proper reading. In cold weather, batteries may look dry.

2. DO NOT add water until a proper temperature is obtained; cold weather can affect the level. If water must be added, use only distilled water.

3. Make sure the electrolyte level is at the level indicator.

4. Replace the vent caps. They must be secured in place during charging.

5. Charge the battery using a constant current charger set to 5% of the six-hour battery capacity. For example, 55 amps for an 1,100 AH (ampere-hour) battery.

• Ordinarily, the charge should take about 3 to 5 hours to complete.

• During the initial charge the volume of electrolyte decreases through electrolysis and evaporation.

Water approved for use in lead-acid storage batteries should be added if the electrolyte level falls below the level indicator.



CAUTION

DO NOT charge the battery at a finish current which exceeded the rating on the battery’s nameplate. Consult the label on the battery for information on cell-type, ampere-hour capacity, charge rate and normal full charge voltage. DO NOT charge the battery at a current greater than 1.5 amp per 100 amp-hours capacity at the end of charge.

If the cell temperature rises higher than +110° F (+61.2° C) either reduce the charging current to half the original value or stop charging until the temperature falls below +110° F (+61.2° C). If the charging current is reduced, extend the charging time accordingly.

6. Refer to “Using a Hydrometer” on page 2-6 for Specific Gravity correction factors dependent upon electrolyte temperature.

7. Continue charging until the cells gas freely and the specific gravity remains constant over a three-hour period. At the end of the charge period the cell voltages rise to about 2.55 volts and the specific gravity rises to about 1.280, corrected to 77° F. 8. When charging is complete, ensure the vented cell caps on the battery are secure.

Battery Restraint System and Roll-out Option The battery restraint should be in place at all times when a battery is installed in the forklift. A switch that detects the battery restraint will disable the forklift if the restraint is not in place.

Roll-out Battery Removal 1. Remove the safety retainer bar, deactivating the safety switch.

2. Position battery roll out stand next to the forklift and align the stand with the path of the battery.

3. Roll the battery onto the stand.

Roll-out Battery Installation 1. Change and charge batteries in accordance with ANSI/NFPA 505.

2. Check to be sure the key is “OFF”.

3. Open the right hand door.

4. If using a roll-out stand, position the battery stand next to the forklift. Align stand with battery compartment. Battery roller stand should be at the same height as the forklift 5. Push battery into the forklift’s battery compartment or lower if using a hoist.

TABLE OF CONTENTS CORRECTIVE MAINTENANCE

Tires Tire Inspection



WARNING

The truck is equipped with tires of a size and hardness that provide the necessary traction and still maintain a proper shape to minimize tipping. To maintain stability and maximum reliability, you must always replace tires with the type originally supplied and torqued to specification as listed in "Specifications" on page 1-10.

IMPORTANT It is recommended to replace worn tires in pairs. A treaded drive tire must be replaced when the tread depth is less than 0.0625” (1.6mm) at the deepest point. Careful driving habits add additional miles to tire life.

NOTE Check all drive wheel lug nuts after 2 to 5 hours of operation when new lift trucks begin operation and on all lift trucks when the drive wheel has been removed and installed.

Tighten the nuts in a cross pattern to the correct torque value of 225 ft-lbs. (305 Nm). When the nuts stay tight for eight hours, the interval for checking the torque can be extended to 200 hours.

Figure 5-9: Tire Tightening Sequence

Visual Inspection 1. Inspect the tires for chunking (or chipping), embedded foreign material (wire, rocks, glass, metal, etc.), cuts, gouges, undercutting or uneven wear.

Remove any object that will cause damage.

2. Check for loose or missing hardware.

3. Remove any wire strapping or other material that is wrapped around the inside of wheel.

4. Make sure drive wheel nuts are tight. Tighten the wheel nuts in a crisscross pattern to a correct torque value (225 ft-lbs (305 Nm)). See Figure 5-9.

Chunked Tires or Embedded Objects IMPORTANT Chunking, or chipping is caused by repeatedly running over objects on a littered floor which can chip away or produce deep cuts to the rubber surface of the tire. Embedded objects, such as glass, metal chips, or nails left in a tire, and truck overloading cause the same effect.

Sharp, rapid turns at quick speeds, jack-rabbit starts and stops and other such bad driving habits can cause the same kind of damage.

1. Remove any embedded foreign material from the tire as soon as it is noticed. Also remove torn pieces of tread.

2. To avoid overloading, always center the payload on the truck to equalize the load on all tires. Do not dangle the load on the ends of the forks. Also avoid fast cornering, which can cause an overload affect.

3. If the tires are chunked bad enough to produce a bouncy ride, replace them.

Undercutting and Uneven Wear IMPORTANT Undercutting is caused by continuous overloads, rapid, sharp turns, operating on slopes, a faulty drive axle, transporting loads with a high center of gravity, or transporting off-center loads.

Uneven tire wear is usually the result of mechanical defects, such as badly adjusted brakes, misaligned wheels (misaligned steer axle), or a faulty drive train.

1. Undercutting causes the rubber to bulge out over the edge of the steel band, cutting the rubber just above the base band.

2. Check that the tires remain centered on the wheels to prevent splitting of the base band and tread separation.

3. Correct such defects as soon as possible.

Flat-spotting IMPORTANT Flat-spotting occurs when:

5-7

TABLE OF CONTENTS CORRECTIVE MAINTENANCE •

1.

3.

4.

The truck has been sitting idle for some time after heavy use and is usually caused by the tires overheating.

• The truck has standing loads (left on the forks overnight).

• Locking the brakes while traveling in either direction on grades (slopes), with or without a load, causing excessive skidding.

Polyurethane tires are extremely susceptible to this type of abuse.

Avoid excessive heat. Where possible, avoid contact with hot metal or operation for long periods in hot oven rooms. Excessive heating will break-down the tire structure. Shields which prevent heat from striking tires directly will often prolong life.

Avoid standing loads. In addition to being unsafe, solid tires will flat-spot when loads are left standing on the truck overnight. In extreme cases, a flat spot develops and the tire bounces with every revolution.

If the tires are flat-spotted bad enough to produce a bouncy ride, replace them.

DO NOT indulge in stunt driving or horseplay where excessive hard braking is needed, especially on grades (slopes).

Extending Tire Life A few simple measures can help increase tire life and reduce maintenance (downtime) and cost of operation.

1. Inspect tires regularly and remove embedded objects when they are found.

2. Check that the tires remain centered on the wheels.

3. Use a replacement tire that meets Landoll B3-30 AC new tire specifications.

4. Keep runways clean and maintain floors in good repair, free from breaks, ruts, cracks and debris.

5. Avoid excessive heat, overloading and standing loads.

6. Regularly check axle alignment and steering.

7. Avoid sharp turns and quick starts and stops.

8. Avoid oil, grease, gasoline and acid. Wipe these compounds off as soon as possible.

DO NOT allow hydraulic oil to drip onto the tires.

Brakes 

CAUTION

Wear eye protection. If brake fluid comes in contact with your eyes, immediately rinse them with water and seek medical attention.



CAUTION

DO NOT release or operate the forklift if you are in doubt about the effectiveness of the parking brake system. Contact your Landoll service representative for assistance.

General Information Braking of the Bendi AC forklift is accomplished by using the drive motor for restraining forklift, or by putting pressure on the brake pedal. When the accelerator is released, the moving motion of the forklift is restrained by the drive motors and occurs in both the forward and reverse direction. Stopping the forklift can also be done by the normal pressing of the brake pedal.

• If a problem is suspected, DO NOT release or drive the forklift until the problem is corrected.

• Safety must always be paramount when working on brake system components.

• Parts that are not in perfect working condition should not be used. It is recommended to only use genuine Landoll parts.

• If you are unsure about a procedure, contact a trained Landoll service technician.

• Wear eye protection. If brake fluid comes in contact with eyes, immediately rinse with water and seek medical attention.

• Use only DOT #3 brake fluid.

• Brake fluid will damage paint. Cover all body parts and be careful not to spill brake fluid during brake maintenance.

• Brake pads must be replaced on both wheels at the same time. NEVER replace the pads on only one wheel to ensure that both sides have equal braking and to prevent premature wear and uneven braking action.

• DO NOT use petroleum based solvents to clean brake parts. Use only brake cleaner or denatured alcohol.

• DO NOT use compressed air to blow particles from the brake assembly.

F-857-0119

TABLE OF CONTENTS CORRECTIVE MAINTENANCE • Make sure you strictly adhere to all clearances and torque specifications.

• If the contact surfaces of the rotor show cracks, score marks, deep grooves, a raised lip on the outer edge, or signs of overheating or warping, the rotor must be replaced.

• The disc brakes are inherently self-adjusting. NO adjustments are necessary or provided.

• When you are finished working on the brakes, test them carefully under controlled conditions before releasing the forklift for operation.

• To remove the rotor you will need a gear puller.

• An ohm meter is required to test the parking brake switch.

• Brake rotor is fitted with threaded holes to ease disk removal. Use steering wheel puller to prevent drive motor damage.

Check Service Disc Brakes • The service brakes are hydraulically-actuated disc brakes, similar to an automotive disc brake system.

The brake calipers are installed onto the gearbox/motor assembly at the rear of the forklift.

• The brakes should be checked every 500 hours of operation. Normal brake pad life should reach approximately 3,000 hours of operation, but that figure can vary widely as determined by the operator and driving conditions. If you are near or beyond this time frame, you must inspect the brakes.

• New brake pads are approximately 0.265” (6.7 mm) thick. Replace them when the pad thickness is 0.0625” (1.588 mm) or less.

• The service brake pedal must also have about 1/2” (12.7 mm) of the travel remaining when the brakes are fully applied. If less than 1/2” (12.7 mm) is available, check the pads for wear and replace as needed.

• Drive the forklift at creep speed and apply brakes lightly to determine if brake pads are contacting the disc (rotor). You should feel a slight pulsating effect as the pads contact the disc.

A few indications of possible brake pad replacement are: • Excess travel of the service brake pedal.

• The forklift pulling to one side when the brakes are applied.

• Squealing is heard when you apply the brakes.

Required Tools Both SAE and metric open-end, box-end, Allen and adjustable wrenches along with assorted sockets and screwdrivers should be available to properly perform maintenance and repair.

• Rotors require a dial gauge to check run-out, and a micrometer, calibrated in ten-thousandths of an inch, to check thickness.

Disc Brake Rotors General Information

• Thickness variations of more than 0.0005” (0.013 mm) can cause pedal pulsation and/or vibration when applying the brakes. A rotor that does not meet these specification must be replaced.

• Whenever servicing and/or replacing a rotor assembly, you must service both sides of the forklift to prevent premature wear and uneven braking action.

• Check the rotors for scoring, cracks, deep grooves, raised lip on the outer edge, signs of overheating, rotor run-out or other damage. Rotor run-out should be measured while the rotor is being installed.

• Rotor thickness measurements may be checked with the rotor installed or removed from the forklift. Use a dial gauge to check run-out. Use a calibrated micrometer, calibrated in ten-thousandths of an inch, to check thickness. See Figure 5-11.

• Measure thickness, using a micrometer, at four or more points on the rotor and make sure all measurements are taken at the same distance inwards from the outer edge of the rotor.

TABLE OF CONTENTS CORRECTIVE MAINTENANCE 10. Remove the master cylinder fill cap and rubber diaphragm (two round head screws). See Figure 5-14.

11. Siphon out as much fluid as possible. Install and tighten the fill cap and diaphragm before removing the cylinder.

12. Place rags under the brake line connections. Have a plastic cup or bag handy to cover the end of the line to limit fluid spillage.

13. Using a flare-nut wrench, disconnect the brake fluid line at the rear of the cylinder.

14. Carefully pull the brake line away from the cylinder.

Seal or plug the brake line and master cylinder port to prevent fluid loss and/or contamination.

15. Disassemble the yoke from the master cylinder crank plate (one 5/16-18 screw and hardware).

16. Remove the two master cylinder mounting bolts and remove the cylinder from the forklift.

17. Remove the reservoir cap and discard any fluid remaining in the reservoir.

18. Mark the push rod lock nut setting, then remove the yoke and lock nut from the old cylinder and install it to the new cylinder, maintaining the same lock nut setting.

19. Replace the new master cylinder in reverse order.

IMPORTANT • The push rod lock nut should be installed so that when the pedal is completely assembled and retracted, the yoke to the master cylinder crank plate hardware is loose.

• Whenever the master cylinder is removed or replaced, the hydraulic brake system must be bled. The time required to bleed the system can be reduced if the master cylinder is filled with brake fluid and bench-bled before installing the cylinder into the forklift.

Bench Bleed the Master Cylinder 1. Support the cylinder in a vise to prevent fluid spillage, while allowing you to push the internal piston with the push rod. See Figure 5-16.

2. Remove the filler cap and fill the cylinder with DOT #3 brake fluid.

3. Slowly push in on the rubber boot and cylinder plunger (push rod) assembly to force air from the cylinder, then hold the push rod in.

5-20

4. Press your finger tightly over the master cylinder outlet port to prevent air from being drawn back into the cylinder when you release the push rod, or feed a separate line (flexible tubing) from the cylinder port(s) and immerse the other end in the container of new brake fluid. Wait several seconds to allow fluid to be drawn from the reservoir to the cylinder bore, then repeat this step. When you push the push rod in again it will force your finger from the master cylinder outlet port to expel any trapped air. Place rags under the brake line fitting to manage any fluid loss.

5. When only brake fluid is expelled from the master cylinder outlet port, hold the push rod in and seat the master cylinder outlet port with an appropriate threaded plug or plastic cap, then release pressure on the push rod.

6. Fill the master cylinder reservoir and install the filler cap and gasket.

1. Remove the left floor plate. See Figure 5-8.

2. First, clean the reservoir cap to avoid fluid contamination, then remove the fill cap an rubber gasket.

3. Additional fluid is needed when the fluid level is below the FULL line stamped in the master cylinder housing body.

4. Add fluid as needed. DO NOT OVER FILL. Use only #3 DOT brake fluid from a clean, sealed source.

5. Reinstall the reservoir fill cap and rubber gasket.

Tighten only enough to provide a leak-proof seal.

F-857-0119

TABLE OF CONTENTS CORRECTIVE MAINTENANCE NOTE DO NOT over tighten. This could crimp, split or damage the seal.

Bleeding Brakes Bleeding the brake system is necessary to remove any air that is trapped when replacing brake lines, brake calipers or the master cylinder. To avoid extensive damage to the system, use only #3 DOT brake fluid.

 •

•

CAUTION

Wear eye protection. If brake fluid comes in contact with your eyes, immediately rinse them with water and seek medical attention.

DO NOT allow fluids to go inside the brake caliper and onto the brake pad. It will contaminate the brake lining and cause failures.

6. Disconnect the battery.

7. Begin a Lock Out/Tag Out procedure.

(SEE PAGE 1-5) 8. Make sure all the other wheels are securely blocked so that the forklift cannot move.

9. Start with the right wheel (the wheel furthest from the master cylinder).

10. Loosen the bleeder fitting slightly, then tighten it where it is snug but can be loosened quickly and easily.

11. Fit a length of tubing over the bleed screw and immerse the other end in the container of new brake fluid. Check that the tubing fits tightly over the bleeder fitting. See Figure 5-17.

12. Check fluid level in the master cylinder. Fill before you begin.

13. Have someone slowly press on the brake pedal several times to build pressure in the system, then hold the pedal down.

NOTE

NOTE

Check the fluid level often during the bleeding operation and add fluid as needed to prevent the level from falling low enough to allow air into the master cylinder. Use only new #3 DOT brake fluid from a sealed container. NEVER use old or used brake fluid. It contains moisture which will deteriorate the brake system components.

Be careful when handling bleeder screws. Rust may cause the fitting to break. Spray the fitting with penetrating oil before attempting to loosen. Use a 6 sided wrench instead of a 12-sided wrench.

14. Loosen the cylinder bleed screw until fluids starts to flow. Watch for air bubbles at the immersed end of the tube.

15. When the brake pedal bottoms, tighten the bleed screw then release the pedal. DO NOT release pressure of the pedal until the bleed screw is tightened.

16. Repeat steps 8 through 11 as many times as needed until the fluid draining into the container is free of air bubbles.

17. Fill the master cylinder fluid level and add as needed before bleeding the other side.

18. Check the operation of the brakes. The pedal should feel solid when depressed, with no softness. If necessary, repeat this procedure.

NOTE Have an assistant available, as well as a supply of brake fluid, an empty clean container, a length of 3/16” (4.763 mm) clear plastic or vinyl tubing to fit over the cylinder bleeder fitting and a six point wrench to open and close the fitting.

NOTE It is necessary to bleed both wheels if air has entered the system. Air in the brake system can be caused by low fluid level or if a brake line has been leaking or disconnected. If the brake pedal feels spongy when pressed and travels almost to the mechanical stop but regains height when pumped, air has entered the system. The system must be bled. If no fittings were recently opened for service, check for leaks that would have allowed air into the system repair leaks before attempting to bleed the system.

Checking and Adjusting Hydraulic Pressure For ease of checking hydraulic pressure, Landoll offers a Pressure Check Kit (P/N 0018152) which includes a 5,000psi (345 bar) gauge, hose, and quick-coupler assembly. If you are using your own system, have shop rags, oil absorbent and a small container ready to collect any oil spills.



CAUTION

DO NOT hold a hydraulic control bottomed out for excessive periods of time. Extreme pressure is applied to the system which can, over periods of time, generate excessive heat, damage oil and internal components. If the pressure is low and cannot be adjusted to the proper value, check the pump and make sure there are no leaks in the hydraulic system. If the pressure is too high and cannot be adjusted to the proper pressure, replace the relief valve.

Hydraulic Control Valve Assembly The following procedure explains how to replace a valve should a sluggish or sticking valve spool be suspect.

Before you service this valve for possible pressure problems, make sure there are no leaks in the hydraulic system and that there is sufficient oil in the tank. Both conditions can contribute to low pressure problems.

The main hydraulic pump for lift, tilt and shift (mast functions) is a fixed displacement gear pump. System pressure must not exceed 3,000 psi, ±65 psi (20 bar, ±4.5 bar) maximum. Actual pressure is determined by mast size, load requirements and lift speed. See reference chart below: Bendi AC Pump Speed in RPMs

TABLE OF CONTENTS

Calibration and Programming Controller Theory of Operation The Bendi AC Series 6 forklifts use Curtis controllers that convert DC battery power to 3-phase AC power by precisely controlling the induction drive for high bandwidth, efficiency and low ripple torque generation.

The Bendi AC forklift uses three (3) controllers (master, pump and slave) and a single dash display to control the various actions of the electrical systems. The master and slave controllers use the two (2) drive motor assemblies along with an analog steer-angle sensor to: • Independently control the inner and outer wheel speed, forklift speed and acceleration.

• Maintain a balanced wheel speed when moving straight.

• Implement a Limited Operation Strategy (LOS) in case of a single drive motor failure, a sensor failure or a partial controller failure for “limp-home” operation.

Dash Display Key Legend 1. “Enter Key” - Used to Enter the Calibration Mode and to make selections after they are located.

2. “Up Key” - Moves “Up” through the selections.

3. “Down Key” -Move “Down” through the selections.

Hold the enter button down until the change is accepted.

When the truck meets or exceeds the value entered in this section, “SERVICE DUE” will be shown on the display. If this feature is not desired, set the value to the factory default of 99900 hrs. Use the Up/Down arrows to manipulate the values by the hundreds.

Steer Potentiometer (POT) Setup - Used to calibrate the steering position potentiometer.

Accelerator Potentiometer (POT) Setup - Used to calibrate the accelerator potentiometer.

Lift Potentiometer (POT) Setup - Used to calibrate the lift potentiometer.

Example: To set the truck hours to 1507.3, you would set this parameter to 150 (1507.3/10=150 with a remainder of 7.3), along with setting the “Remaining HRs in Mins” parameter as explained below.

The value of truck hours that are less than 10. This parameter works in conjunction with the “10s of Hours” parameter to set the total truck hours. Example: To set the truck hours to 1507.3, you would set this parameter to 438 (the remaining hours from the parameter above are 7.3, so 7.3 hrs x 60 min/hr = 438 minutes).

When the hour meter is equal to this parameter, “SRVC DUE” will be displayed on the dash display. IN addition, if “Active Maintenance” parameter is set to “ON”, then the lift will be disabled until this parameter is reset. Setting this parameter to 99900 effectively sets it to off.

Note: Any changes made to the parameters in this menu must be made to both the traction and slave controllers in order to ensure smooth, safe forklift operation.

The rate (in seconds) that is used to slow down the vehicle when the throttle is reduced without being released to neutral.

Larger values represent slower response.

Sets the percentage of the Typical Max Speed above which the HS parameters will be used.

Sets the percentage of the Typical Max Speed below which the LS parameters will be used.

Larger values create a softer reversal from regen braking to drive when near zero speed. This helps soften the transition when the regen and drive current limits are set to different values.

The rate (in seconds) at which the maximum speed set-point is allowed to change when the value of Max Speed is raised. The rate set by this parameter is the time to ramp from 0 rpm to Typical Max Speed rpm. Example: Suppose the Max Speed is raised from 1000 rpm to 4000 rpm. If Typical Max Speed is 5000 rpm and the rate is set to 1.0 seconds, it will take 1.0 * (4000-1000) / 5000 = 0.6 seconds to ramp from 1000 rpm to 4000 rpm.

The rate (in seconds) at which the maximum speed set-point is allowed to change when the value of Max Speed is lowered. The rate set by this parameter is the time to ramp from Typical Max Speed rpm to 0 rpm. Example: Suppose the Max Speed is lowered from 4500 rpm to 2500 rpm. If Typical Max Speed is 5000 rpm and the rate is set to 10.0 seconds, it will take 10.0 * (4500-2500) / 5000 = 4.0 seconds to ramp from 4500 rpm to 2500 rpm
