6.3 CLEANING THE VEHICLE

Before cleaning the vehicle, check the engine, 

axles, gearbox, etc. for leaks. Having cleaned the 

vehicle, it will no longer be possible to check for 

leaks during the maintenance activities.

-

Make sure that doors, windows and roof 

hatch are securely closed during cleaning.

-

When cleaning the universal joint on the 

steering box, the spider seals may be forced 

open by the high-pressure jet of water, so 

that the grease behind them is flushed away. 

As a result, the spider may get stuck, so that 

the steering will "jam".

-

Do not spray directly onto steering ball joints.

-

There is a vent on the power steering fluid 

reservoir of the steering gear. Water may 

enter the reservoir via this vent, which will 

cause damage to the steering gear.

-

When cleaning the radiator/intercooler 

element, be careful not to damage the fins. 

-

Do not aim the high-pressure 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.

-

Make sure that no water can enter the 

differential and gearbox via the vents.

-

Make sure that no water can enter via the 

reservoir vents of clutch, brakes, trailing 

axle, etc.

-

The engine and engine compartment can be 

cleaned with a high-pressure cleaner. Make 

sure in this case not to spray directly onto 

seals, electrical components, such as the 

starter motor, alternator, etc.

-

If an engine encapsulation is fitted, the 

encapsulation panels must be thoroughly 

cleaned after each maintenance job because 

of the risk of fire if the inside of the panels is 

dirty.

-

Do not aim the high-pressure cleaner jet at 

electrical connections such as connectors, 

lighting ducts, etc.

-

Make sure that during vehicle cleaning no 

water enters the air-intake system through 

the air intake or the flexible seals of the inlet.

-

Do not aim the high-pressure cleaner jet at 

the gear lever unit.

-

Do not aim the high-pressure cleaner jet 

directly at the drive shaft seals, such as the 

seals of the spider, intermediate bearing and 

sliding joint.

-

When the vehicle has been cleaned, it must 

be lubricated again with a grease gun or 

through the central lubrication system. This 

is important because it prevents the 

penetration of moisture and dirt at the 

various pivots.
