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
Take care - oil can be hot!
