Carefully read through the Operating Instructions before starting any work!

This particularly applies to the General Safety Instructions section

and the safety instructions in the various chapters.

8.4.2

Maintaining the fuel filter

WARNING

Risk of injury due to highly flammable substances

Highly flammable substances, fluids or gases catch fire.

For this reason:

Smoking, naked flames and sources of ignition are strictly forbidden in the danger zone and close pro
ximity.

Keep fire extinguishers at hand.

Report any suspicious substances, fluids or gases to the person in charge immediately.

Repair leaks.

Stop work immediately in the event of a fire. Leave the danger zone and do not return until it is safe to
do so.

NOTE

Risk of damage due to dirt particles

Risk of component damage due to dirt in the fuel system

For this reason:

Ensure complete cleanliness when working on the fuel system.

ENVIRONMENTAL NOTE

The emerging fuel must not be allowed to pass into the ground or into sources of water.

Cleaning the fuel prefilter

Make sure the engine is stopped before performing maintenance on the fuel prefilter

Close shut-off valves between engine and tank.

Dismantle the fuel prefilter:

1. Unscrew the filter housing

2. Remove the O-ring

from the filter housing

3. Wash out the filter housing

and strainer

clean diesel fuel and blow out with compressed
air

4. Screw the filter housing

with strainer

and

new O-ring

onto the fuel prefilter housing
