Spark plug maintenance
Recommended spark plugs:
A5RTC
In order to guarantee flawless operation of the engine,
spark plugs with the correct electrode gap and free of
residue must be used.
1. Remove the top maintenance flap (fig. 22, no. 6) in
order to access the spark plug (fig. 22/23, no. 22).
2. Remove any dirt from the spark plug recess.
3. Remove the spark plug with the help of the spark plug
wrench provided.
4. Carry out a visual check of the spark plug. Dispose of
the spark plug if the insulation is cracked or chipped. If
you wish to continue using the spark plug, clean it with
a wire brush.
5. Check the electrode gap with a feeler gauge (not in-
cluded in the delivery). The gap should be 0.7 -
0.8 mm. If necessary, correct the gap by bending the
earth electrode.
6. Screw the spark plug in by hand in order to avoid damaging the thread.
7. After manually screwing in a new spark plug, this should be tightened a further
180° with the spark plug wrench provided in order to ensure that the spark plug is
correctly seated.
If a used spark plug is to be reinserted for further use, an additional 45° to
90° turn will be required after initial insertion.
Caution!
The spark plug must be tightly seated. If the spark plug is not tightly seat-
ed it can become very hot and possibly damage the generator. Use only
the recommended spark plugs.
7. Transport and storage
Warning! Set the Start/stop switch (fig. 24,
no. 12) to "Stop"
during transportation of the generator. Al-
ways keep the
generator horizontal to avoid fuel leakage. Fuel
vapours or
spilled fuel can catch fire. Set the tank cover
ventilation and
the fuel cock to "OFF".
The tilting angle of the device should never be more than 15°!
Preparation for long-term decommissioning / storage of device:
1. Make sure that the storage area is free from excess humidity and dust.
2. Drain the fuel:
