7.6. Cleaning the spark arrester

Unscrew the fixing screw of the spark arrester (fig. E - No. 1).
Remove the spark arrester (fig. E - No. 2).
With the help of a wire brush, remove the carbon deposits from the screen of the spark arrester.

Refit the spark arrester on the exhaust silencer protection (fig. E - No. 3), screw the spark arrester fixing screw back on.

7.7. Checking the spark plug

Remove the cap (fig. F - No. 1) from the spark plug, then remove the spark plug (fig. F - No. 2) using a spark plug spanner.
Check the condition of the spark plug:
If the electrodes are worn or if the insulation is split or flaking:
Replace the spark plug.
Fit a new spark plug in position and tighten it by hand to
avoid damaging the threads.
Use a spark plug spanner to tighten the spark plug by 1/2
turn after it is seated to compress the washer.
7.8. Cleaning the generating set
Cleaning with a water jet is not recommended.
Cleaning with high pressure cleaning equipment is forbidden.
Important
Remove all dust and debris from around the exhaust.
Clean the generating set, particularly the alternator and engine air inlets and outlets, using a cloth and brush.
Check the general condition of the generating set and replace any faulty parts.

8. Storing the generating set

If the generating set is not used for a long period, it must be stored in accordance with the guidelines below.
Turn the engine fuel tap (fig. A - no. 6 & fig. C - no. 1) clockwise and drain the fuel into a suitable container.
Start the generating set and let it run out of fuel and stop.
Turn the fuel tap (fig. A - no. 6), to "0" to close it.
While the engine is still hot, change the oil (see § Renewing the engine oil).
Remove the spark plug (fig. F - no. 2) (see § Checking the spark plug) and pour a maximum of 15 ml of engine oil into the cylinder
through the spark plug port before refitting the spark plug.
Without starting the engine, slowly pull the recoil starter handle (fig. A - no. 10) until you feel a certain resistance.
Clean the outside of the generating set, apply an anti-rust product on the damaged parts and cover it up with an all-weather cover
to protect it from dust.
Store the generating set in a clean and dry place.
Otherwise:
Clean the spark plug with a metal brush.
With a feeler gauge, check the electrode gap "X": it must be
between 0.7 and 0.8 mm inclusive.
Check the condition of the washer.
Fit the spark plug in position and tighten it by hand to avoid
damaging the threads.
Use a spark plug spanner to tighten it by 1/8-1/4 turn after it
