FUEL TANK, DRAINING WATER AND DIRT DEPOSITS

This work has to be carried out if dirt or water is found in the pre-separating
glass. Place a clean collecting container below the drain and open the
drain plug on the left front side of the tank a few turns and drain off the
water and dirt deposit. Retighten the drain plug firmly, when clean fuel
starts to emerge from the drain hole.
NOTE
Pay attention that seal is tight.
The point of time at which the tank is to be maintained depends
widely on the purity of the fuel.

TYRES, CHECKING AIR PRESSURE

Measure the air pressure while the tyres are still cold, i.e. prior to starting
work. Do not deflate the tyres, if the pressure has risen on warm tyres.
NOTE
The appropriate air pressure for tyres depends on the type of work
to be performed.
See also section:
"Handling Tyres".

AIR-CONDITIONING, CLEANING CONDENSER

NOTE
Do not wash the condenser off with a steam cleaner or hot water.
This could cause the condenser to become too hot and damage the
air-conditioning.
1.
Open the cover flap on the upper engine hood.
CAUTION
High water or air pressure can damage the radiator segments!
During cleaning, ensure that the gap between the condenser
and the end of the water or compressed-air hose is wide enough
to avoid any deformation of the segments.
2.
If the air-conditioning condenser is dirty, clean it with warm water
or compressed air.
