Fuelling

RISK OF EXPLOSION Fuel and fuel vapour are easily ignited and can explode into flame. Therefore, avoid causing sparks and do not use naked flames such as lighters or matches for illumination.

POSSIBLE RISKS TO HEALTH Diesel fuel and fuel vapour can be injurious to health. Fuel should not be swallowed. Also, avoid prolonged contact with the skin. Do not inhale fuel vapour. Wear protective gloves or use a barrier cream. Do not eat, drink or smoke while fuelling.

AVOIDING DAMAGE TO THE ENVIRONMENT Avoid allowing fuel to overflow. Do not allow fuel to penetrate into the soil, as this is dangerous for the environment. Spilled fuel should be soaked up immediately with a cleaning cloth or binding agent, then disposed of in an environmentally responsible way. Fuel accidents should be reported immediately to the licensee or his agent.

FUELLING FROM CANS If the machine is mostly or regularly fuelled from cans or drums, there is a greater risk that dirt particles and water will penetrate into the fuel system. In this case:

•

always pour in the fuel through a fine-mesh strainer

• •

only use siphon pipes along with a fine filter

•

drain the water and sediment from the fuel tank more often

•

replace all fuel filters at shorter intervals.

drain the fuel filter more often than indicated in the maintenance plan

CAUTION: NEVER FILL WITH BIODIESEL Biodiesel can damage the engine and injection system. Use only diesel fuel produced from mineral oil, which meets EN 590 standard. For more information, contact your dealer’s service department.

SECURING THE MACHINE When fuelling, secure the machine to prevent unauthorized start-up: Park the machine on level ground with sufficient load-carrying capacity, lower the working equipment to the ground, switch off fuel-driven auxiliary heaters and air conditioning systems, switch off the engine, apply the hand brake, take the key out of the key switch for the electrical system. Fuelling always takes place on the ground, with the operator in standing position.

FUELLING Read and apply the ‘Fuelling safety instructions’ before filling up with fuel.

Driving

BEFORE MOVING OFF Before operating the machine, clean your work shoes to remove clinging soil, mud, snow, ice, grease and oil. These could cause the shoes to slip on the steps or pedals, thus causing unwanted movements.

DRIVING OVER LONGER DISTANCES The share should not extend into the steering area of the front wheels, or of the steering linkage. The central warning lamp should not flash when the driver enters, otherwise determine the cause and switch off. If driving on public roads:

Before moving off, adjust the driver’s seat, steering column and mirror, and fasten your seat belt.

•

Keep to the conditions operating licence.

Do not carry passengers on the machine.

• •

Close the driver cab doors.

•

Check the content of the first-aid box. Replace items that have been used, or which have become unusable.

Before moving off, warn any bystanders with the signal horn.

NO TOWING This machine is not suitable for towing trailers or other vehicles; Doing so would cause damage to axles and gears. The tow coupling is intended only for towing or recovering the machine from hazard areas, or for lashing onto transport vehicles; see ‘Towing/recovery’.

DRIVING WITH HANGING LOADS Ensure that the wheels provide sufficient ground adhesion; only this will ensure braking/steering effectiveness. Do not drive with hanging loads positioned cross-wise; Do not attempt a U-turn with such loads. Do not attempt to position such loads using the articulated joint.

the

general

Take along a first-aid box, hazard warning triangle and warning lamp.

With the engine running, check:

•

that the steering wheel moves easily, by turning it briefly to the left and right, and that the steering gear responds.

•

Drive a short distance and operate the brake to check that the service brake is working effectively.

Never allow the machine to roll with the gear lever in the ‘N’ position, for example when driving downhill. If driving with the door open, this should be engaged in the end position. Before moving off, bring the machine up to operating temperature as described in the ‘Operating instructions - warming up’. Only then should the engine be placed under full load.

REVERSING When reversing, the view of the danger area is reduced. Therefore, obtain assistance from an experienced marshaller. Agree on the meaning of signals with the marshaller, to ensure that the signals from the marshaller are correctly understood.

PARKING THE MACHINE Machines parked on slopes can move off by themselves. Therefore, always park the machine on an even, horizontal surface, lower the working equipment and its support to the ground.

Towing /recovery

3.5.2

Transport

Tow the machine with the tow bar or tow rope only.

Only load up and transport the machine if all the requirements of the safety regulations are met.

The tow bar / tow rope should not be damaged. It must be designed so that the calculated load at rupture is three times the tractive force of the towing machine.

Arrange the loading and transport with a company that is experienced in the transport of abnormal loads.

The towing vehicle must have sufficient tractive force. Drive slowly and carefully. No one should be standing near the tow bar/rope. Only tow the machine if the brakes and steering are functional and the machine cannot be transported any other way. If these are not functional, only tow the machine as far as is necessary to recover the machine from danger areas. After recovery, the machine must be secured to prevent it rolling, and prevent unauthorized start-up.

Responsibility for the loading and transport is borne by the transport company or their authorised representative. To reduce the risk of slipping, clean the drive-on ramps and loading area on the transport vehicle, and the wheels of the machine, to remove oil, grease, soil, mud, snow, ice and other matter. Use anchoring equipment with sufficient load-holding capacity (for the weight specifications of the machine, see the ‘Technical Data’ section). 3.5.3

Crane loading

If loading with a crane, lock the articulated joint.

Before transporting over long distances, either repair the machine or load it onto a transport vehicle. Towing speed should not go above 10 km/h. Tow the machine out of the danger area only, otherwise tow it on a low-bed trailer. Towing any further can cause damage to the transmission. 3.5.1

Towing devices

The towing devices should not be used for towing trailers.

Everyday operation

3.7

Read carefully through the sections ‘Basic safety instructions’ and ‘Operation - General information’ and follow the instructions given. Before starting work, examine the worksite for embedded gas and water pipes, and electrical power lines. Damaging these lines can cause a life-threatening situation! Before operating the machine, clean your work shoes to remove clinging soil, mud, snow, ice, grease and oil. These could cause the shoes to slip on the steps or pedals, thus causing unwanted movements. If driving with the door open, engage the door in the end position. Warn bystanders with a horn signal before starting work. Do not drive with hanging loads positioned cross-wise.

Using the grader

Due to the versatility of the grader and the diversity of the materials, there are many possible applications and working methods. We therefore recommend having the driver instructed by the manufacturer. Read and pay attention to: ‘Operating instructions Warming up’. Do not exceed the machine’s permitted transverse/longitudinal tilt angle. Doing so will reduce or interrupt the engine lubrication. The permitted tilt angles of the machine are:

•

Transverse tilt: Left / right 35° 35°

•

Longitudinal tilt: Downward / upward 35° 35°

If the engine temperature, oil pressure or alternator warning lamps come on, lower the working equipment immediately and switch the engine off.

Do not attempt a U-turn with such loads. Do not attempt to position such loads using the articulated joint. Stop working if anyone is standing within the danger area around the machine. Start working only when all persons have moved out of the danger area. Always operate and use the machine in such a way that it remains stable. Ditches and trenches can collapse. Keep at a safe distance.

Use only fibre-free cleaning cloths to clean the hydraulic system or the engine. Cleaning agents and solvents can give off highly inflammable or noxious vapours. Only use such products in areas that are well ventilated - do not inhale the vapour, and do not smoke. Do not allow cleaning agents and solvents to come into contact with the skin. Wear solvent-resistant gloves. Follow the instructions on the product packaging.

HANDLING COMBUSTIBLE FLUIDS When handling combustible fluids:

• •

Avoid contact with the skin. Wear gloves and close-fitting work clothes. Old oils can be injurious to health if they come into contact with the skin. If this occurs, wash the skin thoroughly with warm soapy water and apply a protective cream. Do not use fuels or solvents to clean the skin. If you have accidentally swallowed oil, do not induce vomiting, but seek medial assistance immediately.

VISIBLE OIL LEAKS If there is a visible oil leak, repair the leak immediately.

do not smoke, no open lights or naked flames.

Fuel and other operating fluids often have low flashpoints and are easily ignited. Do not use water to extinguish burning fluids. Use the following:

• • •

Stand out of the direction of the oil spray.

Leaking oil is a danger to the environment! Use an oil binding agent to absorb any spilled oil. Gather up the binding agent and dispose of separately from other waste.

powder extinguisher, carbon dioxide or foam extinguishing equipment.

When it comes into contact with burning fluids, water will vaporise abruptly and cause burning oil to spray over a large area. Water will cause short-circuiting in the electrical system, thus possibly creating additional dangers. Notify the fire department.

FASTENINGS AND FIXING ELEMENTS Check fastenings and fixing elements, for example, bolts, nuts, washers, before re-using.

RELEASE RESIDUAL PRESSURE IN THE HYDRAULIC SYSTEM Hydraulic systems should only be opened after they have been depressurized. Even when the machine is parked on a horizontal surface, the working equipment lowered to the ground, and the drive motor switched off, a considerable amount of residual pressure can remain in some parts of the hydraulic system, for example, primary pressure due to the final hydraulic movements before the machine stops. Residual pressure is only released gradually. If work on the hydraulic system is required immediately after switching off, release the residual pressure as described in the section ‘Hydraulic system’.

Replace damaged parts.

HANDLING OILS AND LUBRICANTS Risk of burns due to the uncontrolled release of hot lubricants or hydraulic fluid. If burns occur, chill immediately with running water, then apply a dry bandage.

PERSONNEL Only carry out inspection and maintenance work on the brakes if you have been trained to work on brake systems. If in doubt, have this work carried out by our service department. Read and apply the section ‘Inspection and maintenance - General information’. SECURING THE MACHINE Only carry out work inspection and maintenance work on the brakes if the machine has been secured as described in the section ‘Securing the machine’. HEALTH PROTECTION Do not inhale abrasion dust - wear a dust mask.

PRESSURE RESERVOIRS The hydraulic system contains pressure reservoirs. These pressure reservoirs contain nitrogen, which is maintained at high pilot pressure. Eve when the pressure in the hydraulic system has been released, the nitrogen in the reservoir remains pressurized. When in operation, pressure reservoirs are quite safe. However, there is a risk of explosion if handled incorrectly! Therefore:

•

Do not perform any mechanical work on the pressure reservoir - no welding or soldering.

•

Inspection and maintenance work should be carried out only by skilled personnel.

•

The system must be depressurized before any inspection or maintenance operations are carried out.

•

Before disassembling the pressure reservoir, wear protective goggles and work gloves.

•

Fill the pressure reservoir with nitrogen only. Never use compressed air or oxygen.

•

Report any faults or damage immediately to the machine’s licensee.

•

Before starting up again, the machine must be inspected by a skilled / experienced technician if the pressure reservoir has been damaged, or the permitted operating temperature or pressure have been exceeded.

Do not remove or paint over warning signs and instruction plates, or the model plate or stamped model badge. Replace illegible or damaged plates immediately.

F106.6 / F106.6A F156.6 / F156.6A

Wheels and tyres

RISK OF INJURY Gas combustion due to heating of the tyres can cause explosions in air-filled tyres. This heating may be due to frequent braking, or due to welding work carried out on the machine. Explosions that occur in this way are much more violent than the normal bursting of a tyre. They can cause pieces of tyre and wheel rim to be flung to a distance of several hundred metres. Exploding or bursting tyres and flying rim pieces can cause very serious injuries, which can even be fatal in some cases.

TYRE PRESSURES Bursting tyres and flying rims or rim pieces can cause serious injuries. Therefore:

•

Before inflating, check tyres, rims and rim parts for damage. Check that they are firmly seated, and check for any foreign bodies that have penetrated.

•

If damage is found, have this repaired at a specialised workshop.

•

Check tyre pressures only when the tyres are hot; tyre pressure increases as the tyres become heated.

•

Use a fill valve with long hose, self-holding nozzle and pressure gauge.

•

Pump up the tyres only with compressed ambient air. Never use combustible gases - risk of explosion!

•

While pumping, keep away from the tyre and stand in the direction of the tyre tread.

•

Watch the tyre and pressure gauge constantly while pumping is in progress, and never exceed the specified tyre pressures.

•

If a wheel is removed, place a safety cage around it.

•

While pumping, ensure that no one is standing near the tyre.

Therefore:

• •

If you suspect that a tyre has become too hot, secure the machine and wait at a safe distance until it has cooled down. Before inflating, check tyres, rims and rim parts for damage. Check that they are firmly seated, and check for any foreign bodies that have penetrated.

•

If damage is found, always have this repaired immediately at a specialised workshop.

•

If you feel that tyres, rims or rim pieces may be unsafe, have the entire wheel removed from the machine at a specialised workshop. When changing tyres, rims or rim pieces, special tools and procedures are required. Therefore, always have this type of work carried out at a workshop that has the appropriate specialised equipment.

•

Do not carry out any work on tyres and rims if you have not received the appropriate training.

Edition 12/2007

Always pump the tyre to the specified air pressure:

•

Excessively high pressures will cause poor handling on the land, and the danger of bursting tyres.

•

Pressures that are too low will lead to increased tyre wear, and will make the machine less stable.

F106.6 / F106.6A F156.6 / F156.6A

WHEEL NUTS Always tighten the wheel nuts with a torque wrench. After a few hours of operation, use the torque wrench to check that they are still firmly attached.

DRIVING ON ROADS When driving on roads, ensure that tyres have the required minimum tread depth and that they are at the correct pressures. Ensure that only tyres of the same size are fitted on the same axle and that they show the same degree of wear. Different tyre diameters can cause damage to the rear-axle differential. You can prevent excess tyre wear by: keeping tyres at the correct pressure; not braking or starting off abruptly; not driving around bends too fast. Before driving on public roads, clean the tyres and spaces between tyres. This will prevent hazards to other road-users caused by dirt tracks left on the road or stones and lumps of earth thrown off by the tyres.

Air conditioning system (optional)

This section describes the inspection and maintenance work to be carried out by the machine operator. In addition, work on the air conditioning system requires specialised knowledge and special tools, and should therefore only be carried out by qualified personnel. In this case, call a workshop that specialises in air conditioning systems. For your own safety, please pay attention to the following instructions: Do not reach inside the equipment and do not insert any objects. Switch off the engine and allow it to cool down before carrying out maintenance work. Disconnect the fan from the power supply, to prevent injuries caused by the fan being switched on accidentally. Some parts of the air conditioning system (for example, heat exchanger and heating resistor on the fan) may still be hot after switching off. Risk of burns. Allow these to cool before opening up the equipment.

WHEN WORKING ON THE REFRIGERANT CIRCUIT (FOR QUALIFIED PERSONNEL): The refrigerant used (R134a) is known as a safety refrigerant. This means that it is non-combustible, non-explosive, non-toxic, non-irritant, odourless and tasteless. Nevertheless, please note the following points: Avoid contact with flowing refrigerant. Chill blains may be occur on skin that has come into contact with refrigerant. Wear safety goggles to protect the eyes. If refrigerant still gets into the eyes, seek medical assistance immediately. Before carrying out repairs to the air conditioning system, drain the system. Do not allow refrigerant to leak out into the environment. Use only approved siphoning equipment. Welding work should not, in any circumstances, be carried out on parts of the sealed system, or in the area immediately surrounding it. Whether the system is full of refrigerant or not, heating it will cause a very high overpressure, which may cause damage to the system or even cause it to explode. Refrigerant containers should not be thrown and, when full, should not be left exposed for long periods to direct sunlight or other heat sources. The temperature of a filled refrigerant container should not be allowed to go above 45 Â°C. It is essential to keep chlorine, chlorine-containing materials, oils and grease out of the refrigerant system. The draining/filling equipment should be used only for R134a.

all warning signs and instruction plates attached to the machine.

The descriptions of work procedures contain information intended only for experienced personnel. Keep the operating instructions stored permanently at the machine.

REPAIR PERSONNEL The repair personnel must have specialised knowledge and experience in repairing this or similar machines. If the personnel lack the necessary skills, they should be carefully guided by experienced personnel. This kind of service can be provided by the service department.

WORKING AT HEIGHTS Wear fall-protections if working at a height.

In exceptional cases, they should only be opened if the personnel know the exact working procedure and the special tools required are available. The operating instructions do not provide any information on this subject.

DISASSEMBLING COMPONENTS Do not disassemble when the machine is warm. Oil, grease, brake fluid or coolant can reach high temperatures and can therefore cause burns and scalds. Allow the machine to cool down. Before starting work, depressurize pipes and hoses, cylinders, radiator, hydraulic tank, compressed air reservoir and other systems and assemblies. Replace damaged components promptly - this will prevent more serious damage later. Clean faulty disassembling.

Attach a tested safety harness - this must be fitted with a fall arrester and safety ropes.

LOCKING THE ARTICULATED JOINT If carrying out repairs near the articulation, lock the articulated joint. Remove the locking device when the work is complete.

when inserting plugs and stoppers.

•

Depressurise the hydraulic tank. To do this, turn the vent valve (1) by about one 1/2 turn. After the air has been released (hydraulic tank is now depressurized), remove the vent valve completely.

•

Place the vacuum pump (3) on the hydraulic tank. The vacuum pump must be at a higher level than the fluid in the hydraulic tank.

•

Press hose fitting (4) carefully into opening (2).

•

Run the cable (5) to the battery. Connect the positive lead (6) to the positive terminal first, then the negative lead (7) to the negative terminal.

•

Switch on vacuum pump (3) at switch (8). The hydraulic system fluid is first pumped up into the hydraulic tank. Air is then drawn continuously into the hydraulic tank by the fluid, causing bubbling at the surface. The resulting vacuum prevents fluid from flowing out of the tank. The pressure on the pressure gauge must be 0.2 bar. If this is not the case, use the rotary switch (10) to adjust to the correct pressure.

General information

When disassembling hydraulic pipes and pumps, fluid will flow from the hydraulic tank. In this case, a vacuum pump can be supplied for the machine as special equipment; when correctly installed, this pump will prevent the hydraulic tank from draining out. For longer repair operations, a case with a complete assortment of environmental protection plugs and stoppers can be ordered. These can be used, for example, to seal off disconnected pipes.
