PREFACE

GENERAL SAFETY STANDARDS PERSONAL SAFETY n

Always use the personal protective equipment when it is required.

n

Pay attention to the squashing risks due to moving parts, oscillations, not correctly fastened materials when lifting operations are carried out or when the loads are moved.

n

Do not wear rings, watches, jewels, unbuttoned or hanging clothes such as scarves, unbuttoned jackets or smocks with open zips that can get entangled in the moving parts.

n

Never carry out cleaning, lubrication or maintenance operations when the battery is connected.

n

If you use compressed air to clean the parts, wear glasses with lateral guards.

SAFETY IN THE WORKPLACE n

Make sure that all working tools are perfectly efficient and ready to use. Keep the working surfaces clean and free from the deposits that settle on the truck parts and cause damage.

n

Keep sparks, free flames and cigarettes at a distance from fuels or flammable materials such as the gas of the batteries.

n

Make sure that the working area is well ventilated, illuminated, dry and clean. Remove any water puddles or oil spots.

n

Make sure that the lifting equipment, devices or machines can bear the load.

n

Never use petrol, gas oil or other flammable liquids as detergents: use commercial non-toxic and non-flammable solvents.

n

In case the interventions are carried out of the workshop, lay the truck flat and block it. If it is necessary to carry out the work on slopes, block the truck and bring it in a flat area as soon as possible within a certain safety limit.

n

Disconnect the batteries and label all controls in order to indicate that an intervention is in progress.

Block the truck and any equipment to be lifted.

n

Do not carry out any intervention on the truck when the operators are controlling it, except that they are qualified operators and help to carry out the intervention.

n

During towing operations use only the prescribed attachment points and make sure that the pins and/or bolts are tightly secured. Lift and move all heavy components by means of a lifting device of proper carrying capacity. Use the proper eyebolts. Make sure that nobody stays near the load to be lifted.

n

Do not twist chains or metal ropes.

n

Do not use damaged or bent chains or ropes: do not use them during lifting or towing operations.

While handling them always wear safety gloves.

n

Do not accumulate cloths soaked with grease or oil: they represent a risk of fire. Always put them in a closed metal container.

n

The oil must be collected and not be let off in the drain pipes; the industrial oils must be disposed of by specialized companies under the protection of the law in force in every Country.

PREFACE

When welding operations are carried out, it is necessary to use proper accident-prevention protections: protective glasses, helmet, overalls, shoes. The protective glasses must be worn also by the people who do not carry out the works if they stay near a welding area.

Before using the batteries, make sure that the cables are connected to the terminals as described: (+) with (+) and (-) with (-).

Do not short-circuit the terminals.

The gas emanated during a recharge is higly flammable. During the recharge of the battery leave the battery compartment uncovered in order to use a more efficient ventilation and remove the plugs.

Do not check the condition of the battery charge by means of “jumpers” obtained by placing metal objects on the terminals.

Before any intervention check if there are no short-circuit elements.

Disconnect the batteries before acting on the electric system.

For the battery chargers and similar equipment, use only auxiliary electric power supply sources in order to avoid any electric shocks.

A fluid passing through a very small hole can be almost invisible but strong enough to penetrate into the skin; in these cases check the fluid by means of a card or a piece of wood.

To check the pressure of the plant use the proper devices.

BANDS, ROPES AND HANGING ROPES: SUGGESTIONS FOR THE USE n n n n n n n n n n n

Register all used hanging ropes, whose features and data are shown on the identification plate.

Do not use bands, ropes or hanging ropes, whose identification plate has been lost.

Always use bands, ropes or hanging ropes of proper dimensions. As far as the hanging ropes are concerned, take into consideration the lifting angle and the unbalance of the load.

The hooks of the hanging ropes must have a proper size according to the hook of the bridge crane and they must move freely.

Position the load in the hook mouth.

Do not place the load on the point of the hook.

During lifting, do not carry out sudden operations that could tear the ropes and the bands.

Do not carry out lifting operations with twisted ropes and bands.

Knots are forbidden.

Always protect the ropes and the bands when they are near sharp edges.

During the movements without load in order to avoid unintentional collisions or hooking, fasten the hooks to the proper seats and lock them.

Use of hanging ropes with unbalanced load If unbalanced loads must be lifted it is advisable to reduce the carrying capacity of the hanging ropes: n Slings with 2 arms, consider them as the slings with 1 arm. n Slings with 3 and 4 arms, consider them as the slings with 2 arms.

Suggestions for maintenance Check the bands, the ropes and the hanging ropes according to the law in force in order to determine their working conditions.

Carry out the replacement in the following cases: n When the components are deformed, cut or when there are cracks, hollows, notches or abrasions on them. n When the wear of the components is higher than 10% of the initial dimensions. n When the sling is overloaded.

DRIVING TORQUE OF SCREWS, NUTS AND CONNECTORS Before the disassembly of the various parts and of the bolts and screws, read carefully the instructions below.

To tighten the screws use the product LOCTITE 270 in order to ensure the safety of the threaded couplings.

DRIVING TORQUE Nm

Nominal diameter

If it is not possible to loosen the screws because this product is used, do not add extensions to the tools, but heat the area (maximum 50° - XXX farehnheit degrees) in oder to eliminate the effect of LOCTITE 270.

In the above-mentioned cases use a small quantity of LOCTITE 270 in the assembly phase (30% of the connection surface).

The driving torque with which the threaded couplings are tightened is very important to ensure the safety of the truck connection.

The bolts and nuts and the corresponding driving torques are shown in the tables on this page.

PREFACE

INSTRUCTIONS FOR THE INSTALLATION OF HOSES AND CONNECTORS Visual check of hoses and connectors: if one of the following conditions occurs, the hose must be immediately disconnected and replaced:

• • • • • • •

movement of the connector on the hose; there are damage, cuts or abrasions on the surface; hardening or stiffness of the hose, burned parts or cracks due to heat; cracks, damage or corroded parts on the connector; leakages from the hose or connector; the hose has permanent folds, squashed or twisted parts; presence of bubbles, softening and wear of the external surface.

Pre-installation inspection: before installing a hose it is necessary to check the conditions of the pipes. First of all check if the type, the size, the reference code and the length are correct and then make sure that there are no impurities, obstructions, bubbles, external layer peeling-off or other visible defects.

Installation: Do not twist the hose, otherwise it could break due to pressure.

Consider a proper radius of curvature in order to avoid the bending or breaking. If the radius of curvature is lower than the minimum radius of curvature allowed, the life of the hose is considerably reduced.

The pressure can change the length of the hose, up to + 2%. Therefore it is advisable to consider a length which is higher than the required one in order to compensate for such changes.

INSTALLATION AND SETTINGS

DELIVERY OF THE TRUCKS MOD. ALL MODELS

Before delivering the truck, the battery on the control (COMBI and/or MPB) must be set.

Before carrying out this operation, we recommend charging the battery so that it can be used at the maximum voltage.

SETTING PROCEDURE A) When the truck is off, remove the MDI connector (if any) from the control and connect the console adapter on the same connector (B) of control MPB. Turn on the truck and select “CONFIG MENU ADJUSTMENT “ and then parameter “ADJUST BATTERY”.

B) Lower the tiller to disable the main remote control switch and by using the “MULTIMETER” detect the battery voltage on the control by positioning the multimeter prods on the battery cable clamps (B+ - B-).

Set the value detected on the “MULTIMETER” (example 25,2V) on the console on parameter “ADJUST BATTERY”. Turn off the key and turn it on to store the value.

To check if the value of the voltage has been stored, select “MAIN MENU’ TESTER” and then parameter “BATTERY VOLTAGE”, if the value does not correspond, repeat the procedure above-described.

NOTE: If the battery is not completely charged, the battery indicator (MDI) does not reset showing the actual charge value, until the battery is completely recharged.

• When the tiller box board must be replaced • When the proportional push buttons for the lifting and lowering must be replaced (when they are installed)

PROCEDURE Step 1 Move the jumper from position “A” (fig. 1) to position“B” (fig. 3). During the acquisition procedure the jumper must be inserted in the external pins of the board.

Step 2 Turn on the truck (Key ON): the CONTROLLER is in acquisition mode.

Step 3 Rotate slowly the speed control forward up to its end of stroke and then release it slowly by letting it come back to the centre.

Rotate slowly the speed control backward up to its end of stroke and release it slowly by letting it come back to the centre.

Step 4 Remove the JUMPER from position “B” and iinsert it into position “A” (travel condition). Turn off the truck (Key OFF). Wait 30 seconds before restarting the truck (Key ON).

The controls has now acquired the potentiometer new values. Close the tiller box and carry out the test by moving the truck. If the acquisition is not successful, repeat the procedure.

NOTE: A new acquisition is required when “ALARM 78” (Vacc not ok) is activated.

MAST MECHANICS 4.00

CHAIN GREASING

The element that gives a long life to the chains is their lubrication.

Therefore a periodical lubrication with a proper oil must be performed by means of a brush or by means of aerosol cans.The frequency with which this operation must be repeated depends much on the type of work and the environmental conditions, but usually every 500 working hours.

4.01 CHAIN ELONGATION

With the use, the chains tend to stretch.Such elongation can be reduced by acting on the chain tightener.

The maximum reduction of the chain elongation is equal to 2%. When this value is exceeded, the chain must be replaced.

4.02

CHAIN MEASURE

Measure the elongation on more sections of 10 pitches, measured on the most stressed sections. This control must be performed about every 1500/2000 working hours. The measure of the 10 pitches is represented in the table below with also an indication of the corresponding chain. If, before the control, the chains have undergone negligible elongations, lower than 2%, this does not mean the chain has remained intact and without any defect.On the contrary, you can have deformations caused by the stress; therefore it is better to carefully check the whole chain in order to control the wear state of the links, the hinge pins, the chain tightener and the chain tightener pin.

OPERATION The electromagnetic brake, which is fixed on the drive motor, is only a parking brake with STOP or EMERGENCY function and it is a spring-loaded brake.

When the electromagnet is supplied, it attracts the braking plate (ref.4) and releases the brake lining making it rotate freely.

When the electromagnet is no more supplied, the springs push the plate downward on the brake lining enabling the braking.

BRAKING SYSTEM

2.00 BRAKING SYSTEMS There are 3 braking systems:

• Release breaking.

• Inversion braking.

• Emergency and parking braking.

A) RELEASE BRAKING It controls the deceleration ramp when the drive control is released.

B) INVERSION BRAKING It controls the deceleration ramp when the drive control is inverted.

The “inversion braking” called also reverse current braking is consists in reversing the current on the motor by changing the direction of travel when the truck is driving.

The braking current must be adjusted so that the truck can stop within a distance not smaller than the length of the truck.

C) EMERGENCY AND PARKING BRAKING The “emergency and parking braking” is obtained by the electromagnetic brake fixed on the drive motor.

The excessive decreasing of the braking space may compromise the good operation of some components of the truck, since during the braking the current on the motor reaches very high values thus causing (in case of wrong adjustment) an early wear of the brushes, the drive motor manifold and the drive wheel.

H G Fig. 5 After assembling the electromagnetic brake unit, it is necessary to adjust the brake lining before using the truck.

For a good braking the distance between the brake lining and the electromagnet (ref.F fig.5) must be not higher than 0.35 mm. Therefore a feeler gauge of that measure is required.

Keep the three nuts loosened (ref.G fig.5), insert the feeler gauge near a bolt (ref.H fig.5), tighten the fastening screw by means of the Allen wrench (ref.I fig.5) Allen wrench and bring the plate nearer at a distance that allows extracting the feeler gauge with a little friction.

INTRODUCTION

SERVICE

GENERAL SAFETY RULES PERSONAL SAFETY •

Always wear the personal protective equipment in situations requiring it.

•

Pay particular attention to the risk of getting crushed due to moving parts, oscillations, material not properly secured when performing lifting operations or moving loads.

•

Do not wear any rings, watches, jewellery, loose or hanging items of clothing such as scarves, unbuttoned jackets or tops with open zippers that can get caught up in moving parts.

•

Never do any cleaning, lubrication or maintenance work with the battery connected.

•

Using compressed air to clean the parts, protect yourself with goggles that have side protection. The maximum air pressure must not exceed 1 bar.

SAFETY AT THE WORKPLACE •

Make sure that all the work tools are perfectly efficient and ready for use. Keep the work surfaces clean and clear of debris that can come into contact with parts of the machine and cause damage.

•

Make sure you keep sparks, naked lights and cigarettes away from fuels or flammable materials such as the gas of the batteries and fuels.

•

Make sure that the work area is ventilated, well illuminated, dry and clean. Remove any puddles of water or oil stains.

•

Make sure that the equipment, devices or lifting machinery used is able to sustain the load in a stable manner.

•

Never use gasoline, diesel fuel or other flammable liquids such as detergents: instead use non-flammable and non-toxic trade solvents.

•

When working outside the garage, move the machine preferably onto the level and block it. If working on a slope is inevitable, block the machine beforehand and move it onto a level area as soon as possible with a certain margin of safety.

•

Disconnect the batteries and label all the controls to signal that work is in progress. Block the machine and every attachment that has to be raised.

•

Never perform any servicing on the machine with persons at the controls, unless they are accredited operators and help with the operation to be performed.

•

When towing use solely the prescribed coupling points and check that the pins and/or bolts are firmly secured before pulling. Lift and handle all the heavy parts with lifting equipment of adequate capacity.

Use the lifting eyebolts intended for this purpose. Make sure no one is near the load to be lifted.

•

Avoid twisting chains or metal ropes.

•

Do not trust bent or damaged chains or ropes: do not use them for lifting or pulling. Always wear the safety gloves to handle them.

•

Do not accumulate rags soaked in grease or oil: they are a great fire hazard. Always put them away into a closed metal container.

•

Used oil must be specially collected. It must not be disposed of into normal drainage system pipes.

Special companies can be employed to dispose of or recycle industrial oils according to the laws in force in individual countries.

•

When welding is necessary, you must use appropriate safety protection: dark goggles, hard hat, overalls, gloves, safety footwear. Dark goggles must be worn also by those who are not doing the work if they remain nearby during the welding.

IV

SERVICE

INTRODUCTION

•

Before using the batteries, make sure that both ends of the cables are connected to the terminals as prescribed: (+) with (+) and (-) with (-).

•

Do not short-circuit the terminals.

•

The gas released when charging is highly flammable. When charging, leave the battery compartment uncovered for more effective ventilation and take off the plugs.

•

Never check the battery charge with "jumpers" obtained by putting metal items on the terminals.

•

Before taking any action, check that no elements are shorted.

•

Always disconnect the battery before working on the electrical system.

•

For battery chargers and similar equipment, use solely auxiliary power sources with an effective ground connection to avoid any electric shocks.

•

Fluid passing through a very small orifice can be virtually invisible and have sufficient force to penetrate under the skin; in such cases, having to make a check, use a card or a piece of wood.

•

Having to check the system pressure, use the specific instruments.

BELTS, ROPES AND SUSPENSION ELEMENTS: USER ADVICE •

Keep a record of all the suspension elements used, stating the characteristics of the suspension elements and the data given on the identification plate .

•

Never leave belts, cords or suspension elements in use whose identification plate has been lost.

•

Always use belts, ropes or suspension elements of suitable dimensions. Concerning the suspension elements, take into consideration the lifting angle and any unbalancing of the load.

•

The bells on the suspension elements must be sized in proportion to the hook of the overhead travelling crane and anyhow must be free to move easily.

•

Always rest the load in the race of the hook.

•

Never load the tip of the hook.

•

When lifting, avoid sudden operations that can jerk on the ropes and belts.

•

Never do any lifting with the ropes and belts twisted.

•

Knots are not permissible. Always protect the ropes and belts when they come into contact with sharp edges.

•

When moving with no load, to prevent impact and accidental hooking, hang the hooks in the bells and close the safety ones.

Using suspension elements under conditions of unbalanced load If lifting unbalanced loads it is advised as a precaution to downrate the load capacities of the lifting elements: • Slings with 2 booms, consider them as corresponding to 1 boom.

• Slings with 3 and 4 booms, consider them as corresponding to 2 booms.

Tips for maintenance Periodically examine the belts, ropes and suspension elements according to current legislation to define their state of service.

Change them in the following cases: • When the components show: deformation, cracks, hollows, cuts or abrasions.

• When the wear of the components exceeds 10% of the original dimensions.

• When the sling shows signs of overloading.

TORQUE SETTINGS FOR SCREWS, NUTS AND FITTINGS carefully.

Before disassembling the various parts and nuts and bolts, read the following

Nominal diameter

To make the threaded matings secure, LOCTITE 270 is used for tightening the screws.

If it is not possible to unscrew the bolts because this product has been used, avoid applying extensions to the tools, instead slightly heat the area (at most 50°C) so as to eliminate the LOCTITE 270 effect.

In the cases described, reapply LOCTITE 270 during installation in a moderate quantity (30% of the mating surface).

The torque setting used for tightening the threaded couplings is extremely important to make the coupling secure and the machine safe.

The tables on this page give the classes of bolts normally used with the relevant torque settings.

INTRODUCTION

CORRECT METHOD FOR APPLYING FEMALE FITTINGS To assure a reliable seal between female fittings and the adapters in this manual, it is necessary to observe the following procedure, which differs from the one for assembling rigid pipes.

Female fittings without a gasket (metal/metal joint) Screw on the nut by hand and then, with the aid of a wrench, tighten by another quarter turn.

Female fittings with O-ring Screw on the nut by hand and then, with the aid of a wrench, tighten by another half turn.

In every case make sure that the pipe is properly aligned before tightening the nut on the adapter.

INSTRUCTIONS FOR INSTALLING FLEXIBLE HOSES AND FITTINGS Inspection of pipes and fittings When even just one of the following conditions arises the pipe must immediately be disconnected and replaced:

• • • • • • •

fitting movement on the pipe; presence of damage, cuts or abrasions on the surface layer; hardening or rigidity of the pipe, presence of burns or cracks due to heat; presence of cracks, damage or severe corrosion on the fitting; presence of leaking points on the pipe or on the fitting; presence of permanent creases, kinking, flattening or twisting on the pipe; presence of bubbles, softening, wear of the outer layer.

Pre-installation inspection Before installing a flexible hose it is necessary to inspect the pipes carefully. First check that the type, size, reference code and length are correct, then check there is no debris, blockages, bubbles, peeling of the outer layer or any other visible defects.

Installation Avoid twisting the pipe, which could cause it to burst under pressure. There must be an adequate radius of curvature to prevent constriction and collapse. The life of the assembled pipe decreases considerably when below the minimum radius of curvature. The pressure can cause changes in the length of the pipe, up to + 2%. It will be wise to have a slightly greater length than the requirement in order to compensate for these changes.

Phase 2 RATCHET - 10 MM SOCKET WRENCH - 5 MM T HANDLE HEX SPANNER Using the socket wrench, loosen the lock nut (ref.A fig.2). Using the hexagonal "T" section spanner loosen the adjusting screw (ref.B fig.3) turning counter-clockwise until, while pressing one of the fork lifting keys on the tiller (fig.4), the pressure diminishes and the oil drains off back into the tank (the lifting action ceases). At this point, turn the adjuster screw in the opposite direction (clockwise) to the point where the forks start to lift again.

Release the lifting button and tighten the screw by a further 1/4 turn.

Carry out a few trial lifts and lowering manoeuvres with the load on the forks, checking that the pressure setting is sufficient to cope with the pressure surge during the initial lifting stage. If this is not the case, tighten the screw by a further 1/4 turn.

Use the socket wrench to tighten the lock nut (ref.A fig.2) to lock the adjusting screw in position.

DISMANTLING OF THE ONE-WAY VALVE The one-way valve is a ball valve that allows the oil to flow in one direction only (lifting cylinder). When the forks are raised and the solenoid valve is not energized, it prevents the oil to return back into the pump and is responsible for keeping the forks in position.

It is possible that leakage occurs due to dirt or breakage of the valve, in these cases proceed to its cleaning or replacement.

ROUTINE MAINTENANCE

SERVICE

WARNINGS •

If maintenance operations are carried out immediately after the truck is stopped, some components of the motor and of the hydraulic system could be hot. Always wear the personal protective equipment in situations requiring it.

•

Do not wear any rings, watches, jewellery, loose or hanging items of clothing such as scarves, unbuttoned jackets or tops with open zippers that can get caught up in moving parts.

•

Never do any cleaning, lubrication or maintenance work with the battery connected.

•

Never perform any servicing on the machine with persons at the controls, unless they are accredited operators and help with the operation to be performed.

•

Using compressed air to clean the parts, protect yourself with goggles that have side protection. The maximum air pressure must not exceed 1 bar.

•

Never use gasoline, diesel fuel or other flammable liquids such as detergents: instead use non-flammable and non-toxic trade solvents.

•

Do not accumulate rags soaked in grease or oil: they are a great fire hazard. Always put them away into a closed metal container.

•

The capacitors in the transistor control unit can keep an electric charge even after disconnecting the battery. To avoid electric shocks and personal injury, discharge the capacitors before inspecting or repairing any component in the electric compartment. Wear safety glasses. Make sure the battery has been disconnected.

•

Do not file or lubricate the contacts of the contactors. This could cause the contacts to stick and, as a result, loss of control and damage to property or injury to people.

•

Used oil must be specially collected. It must not be disposed of into normal drainage system pipes.

Special companies can be employed to dispose of or recycle industrial oils according to the laws in force in individual countries.

•

Fluid passing through a very small orifice can be virtually invisible and have sufficient force to penetrate under the skin; in such cases, having to make a check, use a card or a piece of wood.

•

Protect the hydraulic system from dirt or contaminants getting inside when checking the fluid level of changing the filter.

•

Never operate the pump without an adequate quantity of fluid in the hydraulic system. Operation with low levels of hydraulic fluid will damage the hydraulic pump.

•

Do not place any tools on the battery. Metal items on the battery can generate accidental shortcircuiting and possibly damage or injury.

•

The batteries generate explosive gases. Keep the vents clean. Keep sparks and flames well away from the battery compartment. Pay attention not to create any sparks when disconnecting the battery cables. Disconnect the battery during maintenance work.

•

Always use a spreader bar and slings to raise the battery vertically with the specific eyelets. Do not use chains or slings without a spreader bar, you would risk damaging the battery casing. Check that the battery compartment is clean and dry. When the battery is in service, the aeration plugs must all be installed. If the aeration plugs are not installed, electrolyte can come out, corroding the battery casing and compartment.

SERVICE

ROUTINE MAINTENANCE

•

The acid in the electrolyte can cause injury. If the electrolyte gets spilled it should be cleaned up with water. Neutralize the acid with a solution of sodium bicarbonate (soda). Areas of the skin that come into contact with the acid must be rinsed with water immediately. Acid splashed into the eyes must be washed away with water constantly for at least 10 minutes, then call a doctor.

•

The batteries belong to the counterweight system of the lift truck. When installing a battery that is too small, the lift truck might not have enough weight for the nominal load. When replacing a battery, see the truck identification data plate to check that the battery has the rated capacity and correct dimensions. See “TRUCK AND LOAD CAPACITY IDENTIFICATION DATA” in the “PRESENTATION” section for the exact battery specifications for the lift truck at issue.

•

Do not work under a raised carriage. Lower the carriage or use a safety chain to prevent the carriage from lowering during maintenance work on the mast and on the lifting chains.

•

Never repair damaged forks using heat or welding. The forks are made of steel that is hardened with special procedures. Replace damaged forks.

•

Before servicing the hydraulic system you must eliminate any residual pressure inside it.

Close the valves at the end of the maintenance work.
