d - Tracks leading
across loose, shifting sand
If the vehicle has
become stuck it Is recommended to proceed as follows:
- If the vehicle In
"sitting" in a comparatively small hole
in the sand, place
the sand channels under or in front of
the driving wheels.
If the sandy track is fairly lengthy
the tyre pressure on
all 4 wheels should additionally be
reduced to 0.3 - 0.4
bar (4.3 - 5.7 psi). It is also
recom-
mended to do this
before driving on a lengthy sand track
where there is a
danger of the vehicle sinking in.
Once pre-
pared in this way
the vehicle can even be driven along tracks
lending across very
fine sand. However, the track must
be
very carefully
observed so that the side walls of the tyres
are not damaged by
sharp-edged stones and so that large stones
can be avoided.
The method of reducing
tyre pressure has proved successful and inflating the tyres again afterwards
using a hand pump - or still better, a foot pump is less irksome than
continually shoveling the vehicle free of sand.
e - Fording
Before fording determine
the depth of the water.
If the water is up to 30
cm deep drive through at a low speed; do not switch off the engine while in the
water.
Water with depth of over
30 cm - depths of over 40 cm should be avoided for safety reasons.
The following
precautions should be taken on the vehicle:
Allow engine to cool
down
- Spray entire ignition
system with contact spray
- Position air intake higher
on water-cooled engines
- On
air-cooled engines with vacuum-controlled Intake air pre-heating pull off the
hoses for the regulator In the Intake air cleaner and seal with insulating
tape.
- On
vehicles with air-cooled engines seal the speedometer drive socket on the
steering knuckle using kneadable sealing compound.
After fording the
following work must be performed:
- Switch off engine, check
oil level.
It can be concluded
that water has entered the crankcase
if the oil level has
risen. The water must then be
drained
off immediately. To
do this, carefully unscrew the drain
plug, but press it
upwards against the opening so that the
water which has
settled in the lower part of the sump drains
off.
Take care - oil can be
hot!
