Safety instructions 3.1

General safety instructions WARNING

The correct and safe maintenance of these lift trucks as recommended by the manufacturer is given in this document. Read this manual before you do any maintenance on these trucks. Incorrect performance of maintenance operations is dangerous and can cause injury or death.

After making this product available for the market, the manufacturer cannot be held responsible for modifications made by the customer or user and the consequences thereof, which may alter the conformity of the product with the CE marking.

Do not make changes or repairs that can make the structure of the truck weaker or put safety at risk.

READ THE MANUAL Do not operate the truck unless you have read and understood the instructions in the operation manual. Incorrect truck operation is dangerous and can result in injury or death.

MANDATORY ACTION Knowledge of the system and/or its components is important before you remove or disassemble the components.

The next sections make a list of some basic precautions that you must always obey.

3.1.1

Safety requirements for industrial trucks

The truck meets the essential requirements of Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. The truck is designed and constructed according to European safety standards EN ISO 3691-1, EN 16307-1, EN 11751 and EN 12895. The most important regulations and guidelines are given in these instructions.

As regulations for the end-user may vary from country to country, familiarize yourself with the regulations and standards valid in your country.

Service Manual

To keep the EC Declaration Of Conformity issued by the original truck manufacturer, no modifications or alterations to a powered industrial truck, which could affect, for example, capacity, stability or safety requirements of the truck, must be made without the prior written approval of the original truck manufacturer, its authorized representative, or a successor thereof. This includes the changes affecting, for example, braking, steering, visibility and the addition of removable attachments. When the manufacturer or his successor approves a modification or alteration, the manufacturer or his successor must also make and approve the appropriate changes to the capacity plate, decals, tags and operation and maintenance manuals.

If the end user arranges a modification or alteration without the prior written approval of the original truck manufacturer, its authorized representative, or a successor, the end user must:

•

arrange for the modification or alteration to be designed, tested and implemented by an engineer(s) expert in industrial trucks and their safety

•

maintain a permanent record of the risk assessment, design, test(s) and implementation of the modification or alteration

•

approve and make appropriate changes to the capacity plate(s), decals, tags and operation and maintenance manuals

•

put a permanent and readily visible label to the truck stating how the truck has been modified or altered, together with the date of the modification or alteration and the name and address of the organization that accomplished those tasks, and

•

where appropriate, create a new EC Declaration Of Conformity and sign it.

3.1.3

Service area safety

• • •

Keep the servicing area clean. Oil, grease, and water make the floor slippery.

• •

The truck must always be supported on jacks, if someone works under it.

If possible, make all repairs with the truck parked on a level, hard surface.

Before you start to do repairs on the truck, hang a Do not Operate sign in the operator compartment.

Do not work on any truck that is supported only by lift jacks or a hoist. Always use jack stands or other supports to support the truck before doing any disassembly.

•

Lower the forks or other implements to the ground before performing any work on the truck. If this cannot be done, make sure the forks or other implements are blocked correctly to make sure that they do not fall unexpectedly.

•

Use steps and grab handles (if applicable) when you mount or dismount a truck. Clean mud or debris from the steps, walkways or work platforms before use. Always face the truck when you use steps, ladders and walkways. When it is not possible to use the designed access system, use ladders, scaffolds, or work platforms to perform safe repair operations.

•

To avoid back injury, use a hoist when you lift components that weigh 23 kg (51 lb) or more. Make sure that all chains, hooks, slings, etc., are in good condition and of the correct capacity. Make sure that all hooks are positioned correctly. Lifting eyes are not to be side-loaded during a lifting operation.

•

Make sure that all protective devices including guards and shields are properly installed and functioning correctly before you start a repair. If a guard or shield must be removed to perform the repair work, be even more careful than usually.

•

Always support the mast and carriage to keep the carriage or attachments raised when you perform maintenance or repair work that requires the mast to be in the lifted position.

Service Manual

3.1.4

Personal safety

DANGER Do not lift or transport anyone on the forks or a load pallet that is on the forks. There is a risk of falling, danger to life!

Do not let anyone, under any circumstances, walk or stand under the forks.

Do not place any part of your body between the mast structures or any moving parts of the truck.

•

Remove all rings, watches and other pieces of metal jewellery before you start to do work on the truck. If a metal object becomes into touch with an electrically conductive part, it can cause a short circuit or a serious burn.

•

Always, wear protective glasses and protective shoes when you work around trucks. In particular, wear protective glasses when you use a hammer or sledge on any part of the truck or its attachments. Use welding gloves, hood/ goggles, apron and other protective clothing appropriate to the welding job being performed. Do not wear loose fitting or torn clothing.

3.1.5

Set the power of the truck to OFF and disconnect the battery connector before you open the cover of the motor compartment or the electrical system.

•

Release all pressure in the air, oil or water systems before you disconnect or remove lines, fittings or related items. Release the residual pressure when you remove a pressurized device.

•

If it is necessary to work at height during maintenance work, make sure that you use applicable access equipment and follow the safety instructions of the equipment manufacturer.

• •

With sit-on trucks, remove the seat when you do servicing to the truck.

• •

Do not use your hands to find for oil leaks.

•

Only use clean oil in the hydraulic system. Always fill the oil through the oil filter.

•

Do not mix different lubricants. It is possible that different brands of lubricants are not be compatible with each other. Only use lubricants recommended by the manufacturer.

•

Repairs that need welding must be done only with the applicable reference information and by personnel trained in welding procedures. Determine the type of metal and select the correct welding procedure and electrodes, rods or wire to provide a weld metal strength equivalent at least to that of the parent metal.

•

When you weld, always disconnect the battery and electronic devices.

Remove all paint from a 10 cm radius from the welding point to avoid creating toxic gases during welding.

• •

Use the correct lifting procedures when you remove components.

•

Before you operate, lubricate or repair the truck, read all warning plates and stickers on the truck.

To prevent burns, be careful of the hot sections and hot fluids in lines, tubes and compartments, also when the truck is idle or OFF.

Be careful when you remove cover plates. Gradually, remove the last 2 bolts or nuts at the opposite ends of the cover or device. Before you remove the last 2 bolts or nuts, turn the cover loose to release springs or other pressures.

Be careful when you remove filler caps, breathers and plugs on the truck. Put a cloth around the cap or plug to make sure that you do not become sprayed

Service Manual

or splashed by liquids under pressure. Be aware that the liquids spray and splash more easily immediately after you have stopped the truck, because the fluids are very hot.

•

Only use well-maintained tools. Also, make sure that you use the tools in a correct way.

•

Reinstall all fasteners with the same part number. If a replacement is necessary, do not use a fastener of lesser quality.

•

Do not cause damage to the wiring during the removal process. Do not use damaged wiring. When you install the wiring back, make sure the wiring does not touch sharp corners or hot parts. Put all wiring away from the oil pipe.

•

Loose or damaged fuel, lubricant and hydraulic lines, tubes and hoses can cause fires. Do not bend or hit high pressure lines or install ones that are bent or damaged. Examine all lines, tubes and hoses carefully. Pin hole (very small) leaks can cause a high velocity oil stream that cannot be seen near the hose. This oil can go through the skin and cause personal injury. Use a cardboard or paper to find pin hole leaks.

•

Tighten connections to the correct tightening torque. Make sure that all heat shields, clamps and guards are installed correctly to prevent excessive heat, vibration or rubbing against other parts during operation. Protective shields against oil sprays onto hot exhaust components in the event of a line, tube or seal failure must be installed correctly.

•

Do not operate the truck, if a rotating part is damaged or touches another part during operation. All high speed rotating components that are damaged or altered must be examined for balance before you use them again.

3.1.6

Operating temperature

The ambient operating temperature range of the truck is +5...+25°C. The truck can be operated at a temperature of 0...+45°C for short periods. The recommended humidity is 30...95% (noncondensing).

CAUTION Do not move a damp truck into a freezer storage! Let the truck dry before you do! If you move a damp truck into a freezer storage, there is a risk of malfunction because of ice accumulation!

Maintenance of the mast chains

Edge wear To examine the chains for link plate edge wear, move your finger back and forth over the chain edge.

Copyright © 2018 by MCFE. All rights reserved.

94 (222)

Service Manual

Figure 68: Chains edge-wear check The wear of a link plate edge must not be more than 5%.

Turning or protruding pins A heavily loaded chain operated without sufficient lubrication can cause unusual friction between the pins and the link plates. In extreme cases, the torque can surpass the press fit force between the pins and the outside plates, which can lead to pin rotation. When a chain is operated in such a condition, a pin or a series of pins can start to twist out of the chain, which can cause a failure.

Figure 69: Protruding and turning chain pins Examine the chain pin heads to make sure that all the flats are correctly aligned.

Replace chains with rotated or displaced heads or unusual protrusion immediately. Do not try to weld or drive the pin(s) back into the chain. The wear patterns on the pin heads or the sides of the link plates indicate misalignment.

Such wearing damages the chain and increases frictional loading and must always be corrected.

Cracked side plates Examine all the chains periodically for cracked plates.

Copyright © 2018 by MCFE. All rights reserved.

95 (222)

Service Manual

Figure 70: Cracked side plates Examine the chains carefully from all sides. If you find a cracked plate in the chain, find the cause of the crack to make sure that the condition does not occur again. If there is a cracked plate in a chain, you must replace the chain.

Fatigue cracking Fatigue cracks are a result of repeated cyclic loading exceeding the endurance limit of the chain.

Fatigue cracks almost always start at the pin hole of the link plate (the point of the highest stress) and are perpendicular to the chain pitch line. In their early stages, fatigue cracks are microscopic. Unlike with elongation, there is no noticeable yielding or stretching of the material.

Stress-corrosion cracking Stress corrosion is an environmentally assisted failure, caused by corrosive agents and static stress. In the chain, the press fit pin causes static stress on the pin hole. No cycle motion is required, and the plates can crack even during idle periods. In addition, the reaction of several chemical agents (such as battery acid fluids) with hardened steel can release hydrogen, which attacks and weakens the grain structure of the steel.

The outside link plates of the chain, which are heavily press fitted to the pins, are particularly susceptible to stress-corrosion cracking. Like other cracks, stresscorrosion cracks also initiate at the highest stress point (pin hole), but tend to extend in an arch-like pattern between the holes of the plate. A link plate often has more than one crack.

Copyright © 2018 by MCFE. All rights reserved.

96 (222)

Service Manual

Figure 71: Link plate with stress-corrosion cracks Do not try to electroplate a leaf chain or its components. The plating process releases hydrogen that causes hydrogen embrittlement cracks, which look almost the same as stress-corrosion cracks.

If a plated chain is necessary, contact the manufacturer. Plated chains are assembled from modified, individually plated components, which can decrease the rating of the chain.

Corrosion fatigue Corrosion fatigue is caused by the combined action of an aggressive environment and cyclic stress (unlike in stress-corrosion cracking where static stress alone can be a cause).

Corrosion fatigue cracks look like normal fatigue cracks. Frequently corrosion fatigue cracks and normal fatigue cracks are the same. Corrosion fatigue cracks usually start at the pin hole and move perpendicularly to the chain pitch line.

Ultimate strength failure This type of failure is caused by loads that are far heavier than the maximum load of the mast.

Figure 72: Ultimate strength failure

97 (222)

Service Manual

Tight joints All the joints in a leaf chain must flex freely. Tight joints resist flexing and increase internal friction, thus increasing the chain tension required to fit a given load. Increased tension accelerates wearing and causes more fatigue problems.

Figure 73: Tight joints

5.18.6.4

Inspect the tension of the mast chains

Examine the tension of the mast chains every week. All chain pairs must have equal tension to ensure proper load distribution and mast operation.

To determine if chain pairs have equal tension: 1. Extend the unloaded mast unit to put the chains under tension.

2. Push the center of the chains in the chain pair.

Both the chains must have equal give. If the chains do not give in equally, adjust the chains as instructed in Section 5.18.6.5 Adjust the mast chains.

Electrical operation 6.1

Overview

This chapter gives the electrical operating principles of the lift truck. The standard model and its electrical schematic diagram are used as an example.

CAUTION Always use the correct schematic diagram for the specific model you are servicing. The latest schematic diagrams are available from the Web site of the manufacturer.

To do troubleshooting to a particular component, find the component on the applicable page of the schematic diagram and examine the circuitry associated with it. Keep the schematic diagram at hand for reference while you read the explanation. Make sure that you have the correct schematic diagram with regard to the truck model and its age.

6.2

Power source

This truck product family uses 24 V lead acid batteries that have 12 cells and supply a nominal voltage of 24 volts. The batteries have the maximum capacity of 625 Ah, depending on the truck model. The batteries reside in a separate compartment and are connected to the system through the X1 battery connector. In the electrical schematic diagram, the battery is presented as G1.

6.3

Safety circuit (emergency stop button)

When the emergency stop button (S2) is in its normal closed position, B+ continues to flow to the key switch (S1). B + also flows to the coil of the main contactor K2. The operator can shut down the system power at any time by pushing the emergency stop button. When the button is pushed, the connection opens and removes B+ from the coil of the main contactor K2.

6.4

Key switch

The key switch S1 controls the electrical power supply to the entire system with the help of the main contactor K2. The coil controlling the main contactor K2 contacts is presented on page 3.

The key switch is activated by turning it to the ON position (ECO/PRO). When the key switch S1 closes, B+ flows to the coil of the main contactor K2, the negative is connected to the battery via the controller pin 12 of the connector XA1 and the contactor K2 closes the contacts. Positive electrical power is supplied to the system through the main fuse 9F1.

The fuse 9F1 is rated at 425 A. In the electrical schematic diagram, the location of the main fuses is illustrated on page 1. After the main fuse, the B+ supply is fed to the traction controller. From the traction controller it continues to the pump motor. The pump motor negative is controlled by the pump controller. In the schematic diagram, the M2 contacts are presented on page 2.

The traction controller controls the traction motor. In the schematic diagram, the M1 contacts are presented on page 2. The main voltage is supplied to the terminal B+ on the traction controller.

6.5

Traction

The traction controller controls the movement of the truck. Before the truck can be operated, the battery must be connected, the key switch must be closed and the system must have passed the self-test procedure.

When the power of the truck is set to ON and the truck in the standby mode, it can be operated by turning the accelerator at the steering wheel forward or backward. In the electrical schematic diagram, the accelerator is presented on page 5. Acceleration and travel speed varies according to the movement of the accelerator.

6.6

AC motor operation

In the induction motor (= asynchronous motor), the stator is powered with alternating current and designed to create a rotating magnetic field, which rotates in time with the AC oscillations. In the induction motor, the rotor rotates at a slower speed than the stator field and thus the magnetic field through the rotor is changing (rotating). The rotor has windings in the form of closed wire loops. The rotating magnetic flux induces currents in the rotor windings as in a transformer. These currents in turn create magnetic fields in the rotor that interact with the stator field. Due to Lenz's law, the direction of the created magnetic field is such as to oppose the change in current through the windings.

The cause of induced current in the rotor is the rotating stator magnetic field, so to oppose it, this rotor starts to rotate in the direction of the rotating stator magnetic field to make the relative speed between the rotor and the rotating stator magnetic field zero.

For these currents to be induced, the speed of the physical rotor must be lower than that of the stator's rotating magnetic field, or the magnetic field would not be moving relative to the rotor conductors and no currents would be induced. As the speed of the rotor drops below synchronous speed, the rotation rate of the magnetic field in the rotor increases, inducing more current in the windings and creating more torque. The ratio between the rotation rate of the magnetic field as seen by the rotor (slip speed) and the rotation rate of the stator's rotating field is called "slip". Under load, the speed drops and the slip increases enough to create sufficient torque to turn the load. For this reason, induction motors are sometimes referred to as asynchronous motors. An induction motor can be used as an induction generator, or it can be unrolled to form the linear induction motor, which can directly generate linear motion.

A contactor is an electrically-controlled switch used for switching a power circuit, similar to a relay, but with higher current ratings. A contactor is controlled by a circuit, with a much lower power level than the switched circuit.

8.2.5.1

Contactor functionality check

1. Measure the resistance between the coil A1 – A2 terminals.

The resistance must be ~55 Ω.If the resistance is ~0 Ω or ~∞ Ω, replace the contactor.

2. Measure the resistance between the main switching contacts 1-2.

The resistance value must be ~∞ Ω.If the value does not match the above, replace the contactor.

3. Supply +24 Vdc between the A1 (+) and A2 (-) terminals.

4. Measure between the main contacts 1 – 2 that the contacts are closed.

If the contacts are not closed, they are stuck together. In that case, replace the contactor.

Motor compartment CAUTION

Before you open the motor compartment covers, set the power of the truck to OFF position and disconnect the battery connector.

Before any inspection or repair work, discharge the controllers. Record the positions of cables and harness connections before disassembly.

Use the correct power cables and terminate marked cable ends to the correct terminals marked on the motor. Cables terminated at the wrong terminals can cause the motor to rotate in the opposite direction when activated.

CAUTION If the high-power cable terminals of the battery-operated vehicle are not tightened correctly, the increased contact resistance causes excessive heat generation, and can even cause a fire. To prevent accidents and equipment problems, examine the torque of the high-power cable terminals regularly.

Do not pull the cables when you examine the connections or during adjustment. If the cable terminal sections are moved, tighten the connections again.

Diode test with a multimeter

To make sure that the diode works correctly, do a basic diode test: 1. Remove the horn.

2. Set the multimeter to the resistance or diode range.

3. Connect the cathode terminal of the diode to the positive terminal of the multimeter and the anode to the negative or common terminal of the multimeter.

4. Set the multimeter to read the resistance or diode.

The reading must be low or 0.

5. Reverse the connections.

The reading must be high or OL. If the results do not agree with the expected values, the diode connection is damaged:

•

If the results are opposites of the expected values, the diode was assembled with incorrect polarity.

•

If the resistance values are ~0 Ω or ~∞ Ω in both directions, the diode is shorted or broken and must be replaced.

The principle of the hydraulic operation of the truck is as follows:

Lifting 1. The electrical motor operates the hydraulic gear pump.

2. The hydraulic oil is pressurized.

3. The fluid pressure is maintained using the relief valve, which opens at a certain pressure. In such cases, the hydraulic oil is flows back to the fluid tank. The opening pressure of the relief valve is shown in the hydraulic schematic diagram.

4. The pressurized hydraulic oil flows through the check valve to the lifting cylinder.

5. The lifting cylinder piston lifts the forks.

The solenoid valve is an electrically controlled hydraulic valve that has 2 main parts: a solenoid (coil) and a valve. The solenoid converts electrical energy into mechanical energy which, in turn, opens or closes the valve mechanically. This basic ON/OFF function is used to control the oil flow to the cylinders.

To lift the lifting platform, the system uses the pump motor and the solenoid valve for the lifting platform.

To lower the lifting platform, the system uses the proportional valve and the solenoid valve for the lifting platform.

To lift the forks, the system uses the pump motor and the solenoid valve for forks.

CAUTION Before you do maintenance on the truck you must release the pressure from the system. Lower the lifting platform and the forks to the down position. Lift the lifting platform with a lifting device and put supports below it, before you begin the maintenance.

After you have replaced a part in the solenoid valve unit, you must bleed the system and do a test lifting to make sure that there are no oil leaks. Also, make sure that there is enough oil in the hydraulic oil tank.

NOTE: Add hydraulic oil when necessary!

Alarm codes TRUCKTOOL To view the possible alarms, see the instructions of TruckTool.

NOTE: During resistance measurements, make sure that the battery connector is disconnected, and that the voltage at the measured circuit is 0 V. Before you start to do troubleshooting to the truck:

•

Make sure that all the power supplies, fuses and connections are not damaged.

•

Make sure that the wiring harness is not damaged. Make sure that the related connections do not have loose pins and so on.

•

Make sure that the truck frame is isolated from the battery positive and negative. Measure this from both sides of the drive contactor. Make sure that there is no short-circuit or low resistance between the positive and negative from the terminals of any controller (B+ and B- terminals).

•

Make sure that the battery is not damaged. Measure the battery voltage when idle, and during full speed lift. The battery voltage must stay over 16.8 V.

•

Make sure that the battery is fully charged. Low battery voltage can cause error messages.

•

Set the power of the truck OFF and ON again. This can clear some error messages.

• •

Look at the status of the truck display (warning/alarm/info code).

Read the alarm status from each controller. Try to make an overall picture of the root cause for the event code(s).

NOTE: During resistance measurements, make sure that the battery connector is disconnected, and that the voltage at the measured circuit is 0 V.

WARNING FOR SAFETY OBSERVE THE FOLLOWING WARNINGS

1. Do not operate this truck unless you have been trained and authorized to do so. Read all warnings and instructions in operator's manual and on this truck, Operation & Maintenance Manual is supplied with this truck or available from our Forklift truck dealers.

2. Do not operate this truck until you have checked its condition, Give special attention to Tires, Rims, Horn, Lights, Battery(s), Controller, Lift and Tilt systems including Forks or attachments, chains, cable and limit switches, brakes, steering mechanisms, Fuel system, hydraulic hoses and guards.

3. Operate truck only from designated operating position. Never place any part of your body into the mast structure, between the mast and the truck, or outside the truck. Do not carry passengers.

4. Do not operate truck without overhead guard, unless conditions prevent use of a guard. Use special care if operation without overhead guard is required.

5. Do not handle loads which are higher than the load backrest or load backrest extension unless load is secured so that no part of it could Fall backward.

6. Do not handle unstable or loosely stacked loads. Use special care when handling long, high or wide loads to avoid losing the load, striking bystanders or tipping the truck.

7. Do not overload truck. Check capacity plate for load weight and load center information.

8. Start, stop, travel, steer and brake smoothly. Slow down for turns and on uneven or slippery surfaces that could cause truck to slide or overturn. Use special care when traveling without load as the risk of overturn is greater.

9. Elevate Forks or other lifting mechanism only to pick up or stack a load. Lift and lower with mast vertical or tilted slightly back- NEVER FORWARD. Watch out for obstructions, especially overhead.

I0. Operate tilting mechanism slowly and smoothly. Do not tilt forward when elevated except to pick up or deposit a load. When stacking, use only enough backward tilt to stabilize load.

11. Travel with load or lifting mechanism as low as possible and tilted back. Always look in direction of travel. Keep a clear view, and when load interferes with visibility travel with load or lifting mechanism trailing (except when climbing ramps).

12. Use special care when operating on ramps — travel slowly, and do not angle or turn. When truck is loaded, travel with load uphill, when truck is empty, travel with lifting Mechanism downhill.

13. Observe applicable traffic regulations. Yield right of way to pedestrians. Slow down and sound horn at cross aisles and wherever vision is obstructed.

14. When using Forks, space Forks as far apart as load will permit. Before lifting, be sure load is centered and Forks are completely under load.

15. Do not allow anyone to stand or pass under load or lifting mechanisms.

16. Do not lift personnel except on a securely attached specially designed Work Platform. Use extreme care when lifting personnel. Place mast in vertical position, place truck controls in neutral and apply brakes. Lift and lower smoothly. Be available to operate controls as long as personnel are on the Work Platform. Never transport personnel on Forks or Work Platform.

17. Before getting off truck, neutralize control, fully lower lifting mechanism and set parking brake.

When leaving truck unattended, also shut off power.

18. Stay inside compartment until truck comes to a complete halt.

19. Be aware of steering direction inherent to specific chassis.

20. Extend Forks/attachments only to pick-up or discharge loads.

21. Travel with reach mechanism/attachment fully retracted and Load adequately centered during travel.
