30.1.1 BLEEDING THE FUEL SYSTEM
• Fuel in the injection system is under pressure.
Use goggles and rubber gloves if you work on the injec-
tion pump. If you are hit by a high-pressure fuel stream,
immediately seek medical attention.
1 - For maintenance operations, park and secure machine as
described in chapter "22.1 Preparing the Machine for Main-
tenance".
2 - Loosen the vent screw (1) at the water separator.
3 - Unlock the fuel pump (2) by pressing the cover down and
swivelling it out of the way.
4 - Operate fuel pump until bubble-free fuel leaks out at the
vent screw.
5 - Re-tighten the vent screw.
6 - Loosen the vent screw (4) at the fuel filter (3).
7 - Operate the fuel pump until bubble-free fuel leaks out at the
vent screw.
8 - Re-tighten vent screw.
9 - Re-lock the cover of the fuel pump.
• Danger of injury! When the engine is running, you may
hurt yourself on the movable components inside the en-
gine room.
Do not perform any operation in the engine room with the
engine running.
10 - Start up the engine and bleed the lines, one after the other,
while engine is running until the engine is running regularly.
• If the fuel system has run empty during driving, or if re-
pairs or maintenance operations are to be performed, it is
necessary to bleed the system.
