6.3 CLEANING THE VEHICLE

Before cleaning the vehicle, check the engine,
axles, gearbox, etc. for of 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 power steering reservoir via this
vent, which will cause damage to the
steering gear.

-

When cleaning the radiator/intercooler, 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
starting motor, alternator, etc.

-

When cleaning UPEC engines with a high-
pressure cleaner, do not aim it directly at the
pump units. Water could penetrate into the
protective covers via the vent holes. This
could result in faults in the electrical
connections of the pump units.

-

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 of 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.
