6. When repairing / servicing the vehicle
Prior to carrying out any work on the electronic air suspension (other than
calibration), place axle stands under the chassis.
– Check the tightness of the wheel nuts according to recommendations.
– Prior to tilting the cab:
• Ensure there is enough necessary space available in front of the vehicle.
• Set the limits of a safety perimeter
around the cab inside which you must pay
attention that nobody tries to cross that area or park in it, not only during the cab
tilting operations but also when the cab is fully tilted.
• Stop the engine, put the gear lever into neutral and make sure that no object is like-
ly to fall onto the windscreen. If a refrigerator is fitted, drain it. Close the doors.
• Tilt the cab as far as possible. If the cab is only partially tilted, wedge it to prevent
accidental movement.
– If the engine is running:
• Do not approach moving parts (fan, drive belts, etc...).
• Do not turn off the electrical power supply (shut down the engine first).
– When climbing up onto or down from the ramp behind the cab (tractor), use the steps
and grab handles provided. Never jump down from the ramp. Take care not to burn
yourself (on the vertical exhaust pipe and silencer).
– Fuel is inflammable: if the fuel filler cap is open, smoking is forbidden and there must
be no naked flame in the vicinity.
– Batteries are filled with acids, which can cause serious injuries. They must be handled
with great care.
– If you start the engine using an external power source:
• Use cables of the correct dimensions.
• Make sure that the + and - polarities are connected properly.
– When changing a fuse, it is vital to use another fuse of the same size.
– Only specialists should install additional power lines.
– The installation of additional air lines requires a technical study carried out or
approved by the manufacturer.
– It is strictly forbidden to heat polyamide hoses (braking circuit pipes).
– Raising the vehicle with a jack. chock the wheels prior to jacking.
– Immobilizing the vehicle: use one or several wheel chocks as necessary.
– Wheels and tyres:
• Never check tyre pressures or inflate or deflate a tyre, which is hot.
• Never stand in front of a tyre when checking the pressure or inflating it.
• When fitting a roadwheel, take great care to centre wheels fitted with centring
clamps (for trilex wheels, position the clamp at the segment crossover point).
