Crawler tension - adjust
Tightening the crawlers

Remove the crawler tensioner cover (1).

Position the grease gun on the grease nipple (2).

Pump the grease gun until the specified crawler tension is ob-
tained.
Loosening the crawlers

Loosen the pressure valve (3) carefully.

If the grease is emitted from the pressure valve in a controlled way, start the engine and rotate the lifted crawl-
er briefly.

Screw in the pressure valve and torque to 98-108 Nm.

Check and adjust the crawler tension, if necessary.
Water separator - cleaning

Open the engine compartment cover (page 144).

Turn the cock (3) to the “OFF” position.

Unscrew retainer (1) while holding on to the cup (2).

Remove the cup.
Do not unscrew the pressure valve too quickly or completely. Otherwise grease can squirt out at high
pressure from the opening of the clamping cylinder.
Water and impurities in the fuel settle in the water sep-
arator. A red plastic ring (4) in the water separator
floats on the water. If such substances have deposited
or the plastic ring has come up to the mark (5), the wa-
ter separator must be emptied.
Place a cleaning cloth under the water separator to
prevent fuel from running onto the ground.
