1. Loosen the cover spring clips (fig. 27, no. 19) of the air filter (fig. 28, no. 20), remove the
air filter cover and remove the air filter.
2. Wash the air filter in non-flammable solvent and dry it carefully.

Spark plug maintenance
7.4.
Recommended spark plugs:
BP6ES, SPR6ES (NGK), F6TC, F6RTC (LD)
In order to guarantee flawless operation of the engine,
spark plugs with the correct electrode gap and free of resi-
due must be used.
1. Pull off the spark plug connector
(fig. 29, no. 22).
2. Remove any dirt from the spark plug recess.
3. Remove the spark plug (fig. 31, no. 23) with the help of
the spark plug wrench (fig. 29, no. 21) 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 (see fig. 30) with a feeler gauge (not included in the delivery).
The gap should be 0.7 - 0.8 mm. If necessary, cor-
rect 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 seated it can become very hot and possibly damage
the generator. Use only the recommended spark plugs.
