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 „1“anti-clockwise by at least 90° using suitable
pliers. The lead seal wire will break off.
– As soon as the emergency start lever is in the starting
position, the electric starter or recoil starter can be used.
The oil level must always be checked before an emer-
gency start, as insufficient oil pressure can lead to com-
plete 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 CLOCK-
WISE TO THE STOP POSITION.
Immediately after a period of emergency running, ascer-
tain the cause of the fault and have it rectified. 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 (Motorenfab-
rik HATZ assumes no liability).
In case of difficulty contact the nearest HATZ service
point.
Automatic electrical shutdown system
Model with error memory
This is characterized by a brief flashing of all pilot lamps
once the starter key has been turned to position I.
Important!
If the engine cuts out immediately after starting or
switches off by itself during operation, a monitoring ele-
ment in the automatic shutdown system has tripped. The
corresponding indicator light will come on. After the
engine has stopped, the display continues to glow for
about 12 seconds. The electrical device then switches
itself off automatically. The display lights up again after the
start key has been turned back to position 0 and then to
position I again.
Trace and eliminate the cause of the operating fault
before trying to restart the engine.
The display light goes out when the engine is next started.
