The fresh air openings, the windshield and the
front fenders must be generously masked off
before cleaning and preserving.
be determined by each workshop itself.
Masking is necessary in order to ensure that
no materials whatsoever, e.g. cold cleaning
solvent, wax or similar, penetrate inside the
car (difficult to clean).

3
The screw joint holding the brake fluid
reservoir must be masked off with adhesive
tape, which is to be removed again after
preservation of the engine compartment.

4
Mask off the ventilation hole for the
diaphragm chamber in the pressure control
valve in the cylinder head cover.

5
Cleaning is to be performed when the engine
is no hotter than hand-hot (at the exhaust)
using a demulsifying cold cleaning solvent
(short action time) and a high-pressure hot-
water cleaner, depending on how dirty the
engine is.
"Demulsifying" means that a mixture of oils
and greases in water separated in the oil
separator pipe.

6
When cleaning the component compartment
behind the engine compartment: Spray only as
much water as necessary under very low
pressure.Electronic control modul es must be covered
beforehand; any that become wet must be
dried afterwards.

7After washing/preserving the engineLubricate throttle cont rol linkage and check
for ease of movement and wear.
8
Preservation is to be performed only when the
engine compartment is dry and using properly
functioning commercially available
equipment.Only use approved wax preservation agents.
Airless devices produce the least
contamination.

9Do not spray the follow ing with preservation
wax:Electrical and electroni c components, belt
drive (belts and pulleys), exhaust pipe and
muffler in component compartment.

1. Clean area around oil fi ller screw (14f).
2. Remove oil filler screw (14f).
The front axle gear is correctly filled when the oil reaches the lower edge of the filler opening. Top up
if necessary. If the oil level check is car ried out when the front axle gear is warm , do not drain off oil
discharged as a result of thermal expansion.
