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.
