Inspections and Maintenance
- Do not spray directly onto steering ball joints.
- The power steering fluid reservoir is fitted with a vent. Water may enter the
reservoir via this vent, which will cause damage to the steering gear.
- When cleaning the radiator/intercooler, take care not to damage the fins.
- Do not direct the high-pressure cleaner/steam cleaner jet too long at the
air-conditioning system condenser. As a result of the high temperature, the
pressure in the system will rise too high, which may cause damage to the
system. Parts of the air-conditioning must not be cleaned with the aid of a
high-pressure/steam cleaner as this can cause damage to the seals.
- Make sure that no water can enter the differential and gearbox via the vents.
- Make sure that no water can enter via the reservoir bleed screws of the clutch,
brakes, trailing axle, etc.
- The engine and engine compartments can be cleaned with a high-pressure/
steam cleaner. Avoid spraying directly onto electrical components such as the
fuel system pump units, electronic units the starter motor, alternator,
air-conditioning compressor, headlights, etc.
- Carefully clean the engine encapsulation and its fittings. Remove any spilled oil
and diesel oil to avoid the risk of fire.
- Do not aim the jet of water directly at electrical connections such as connectors,
cable plugs in the vehicle lighting system, etc. Also do not aim the jet at the gear
lever unit.
- When cleaning the vehicle, make sure that no water can enter the air inlet
system via the air intake or its flexible seals.
- When the vehicle has been cleaned, it must be lubricated again with a grease
gun or via the automatic lubrication system. This is important because it
prevents the penetration of moisture and dirt at the various pivot points.
