Note
Self locking nuts must always be replaced by new
ones after they have been unscrewed.
Fig. 68
*Strength classes for screws with untreated, non-
lubricated surfaces. The quality designations are
stamped on the screw heads.
8.8 = 8 G
10.9 = 10 K
12.9 = 12 K
The values result in a 90% utilization of the screw's
yielding point at a coefficient of friction of
μ
total =
0.14.
The compliance with the tightening torques is to be
checked with torque wrenches.
The tightening torques are not applicable when us-

5.23 Engine conservation
!
Danger
Fire hazard!
When working on the fuel system do not use
open fire, do not smoke, do not spill any fuel.
!
Danger
Health hazard!
Do not inhale any fuel fumes.
Environment
Catch running out fuel, do not let it seep into
the ground.
If the engine is to be shut down for a longer pe-
riod of time (e.g. over winter), we recommend
the following engine conservation measures
to avoid corrosion:
Clean the engine:
l
For this purpose use cold cleansing agent or,
even better, a steam cleaner.
l
Run the engine warm and shut it down.
l
Drain the still warm engine oil and fill in fresh
engine oil.
l
Drain the fuel from the tank.
