Important:
– The hoses must be correctly connected
as shown in Fig. 113.
If the hoses are wrongly connected, the
automatic engine protection function is
no longer available, i.e. the engine is not
shut down automatically if lubricating oil
level drops too low.
– On older engine versions, hose (113/1)
is connected to the fuel delivery pump.
This has no effect on the basic function
of the device.
Operational check with start release
device installed:
– Turn lever (114/4) clockwise; locking
collet (114/13) must move to the „Stop“
position (Fig. 116). Release the lever;
the locking collet must move back to the
„Start“ position.
– Prime the fuel delivery pump with the
lever and at the same time check
whether the piston in cylinders (114/2)
moves the lever (114/4) correctly. Also
check the cylinder and hose unions for
leaks. When the lever is no longer
actuated, spring (114/9) exters pressure
on the piston, which should then move
back slowly (see Fig. 116).
Note:
If the fuel tank is located at a higher level
than the fuel delivery pump, the difference
in height between the fuel level in the tank
and the fuel delivery pump must not
exceed 2 metres.
Failing this, the automatic engine protec-
tion device will be put out of action and
the engine then cannot be switched-off
electrically.
