Fuel shut-off valve, stop solenoid
(additional equipment)
15
As soon as the starting key is at Position I,
fuel shut-off valve „1“ is electrically released.
The fuel feed to the injection pump is then open
and the engine is ready to start.
When the engine is running, turning the starting
key to position 0 closes the shut-off valve and
interrupts the fuel supply to the injection pump,
so that the engine stops; Chapter 4.3.
This shut-off valve is also used for the automatic
electrical shutdown system.
Emergency start
If the shut-off valve is blocking the fuel supply
as a result of an electrical fault and the engine
therefore cannot be started, an emergency start
can be attempted.
Proceed as follows for this:
– For emergency starting, turn the lever at fuel
shut-off solenoid „2“ anti-clockwise by at least
90° using suitable pliers. The lead seal wire
will break off.; Fig. 15.
– As soon as the emergency start lever is in the
starting position, the electric starter or recoil
starter can be used; Chapter 4.2.2 and 4.2.3.
The oil level must always be checked before an
emergency start, as insufficient oil pressure
can lead to complete damage of the engine
within a very short time.
After this, the engine can only be
stopped with the starting key in the
emergency operating mode if the emergency
starting lever is first turned back clockwise to
the stop position.
Immediately after a period of emergency
running, ascertain the cause of the fault and
have it rectified; Chapter 6.
Have the emergency-starting lever sealed once
again by a HATZ service point.
When the automatic electrical shutdown system
is used, the emergency start described above
means that liability for risks must be accepted
by the operator (Motorenfabrik HATZ assumes
no liability) !
In case of difficulty contact the nearest HATZ
service point.
