Pay attention to utmost cleanliness
when refuelling and working on the fuel
system. Carefully clean the area
around the affected parts. Blow damp
areas dry with compressed air. Obser-
ve the safety regulations and national
specifications for handling fuels. Dis-
pose of leaking fuel and filter elements
properly. Do not allow fuel to seep into
floor. After all work on the fuel system,
the system should be vented, a trial
run performed and the tightness chek-
ked.
Additional venting of the fuel system by
a 5 minute trial run at idle speed or on
low load is absolutely essential.
Mortal danger! Do not work on the fuel
system while the engine is running.
The system is under high pressure! Do
not get near to a leak in the high pres-
sure system because the fuel jet can
cause severe injury! Wait 30 seconds
after switching off the engine before
working on the fuel system. In case of
leaks in the fuel system, contact your
DEUTZ partner immediately.

system. Clean and dry the engine and
the engine compartment thoroughly
before starting work. Cover parts of the
engine compartment from which dirt
could be loosened with a new, clean
foil. Work on the fuel system may only
be carried out in an absolutely clean
