7.5. Cleaning the spark arrester
Undo the mounting nuts (diag. E – no. 1) and remove the exhaust silencer (diag. E – no. 2).
Undo the mounting bolts on the exhaust silencer guard (diag. E – no. 3) and remove the exhaust silencer guard (diag. E – no. 6).
Undo the mounting bolts on the spark arrester (diag. E - no. 4).
Remove the spark arrester (diag. E - no. 5).
Using a wire brush, remove the carbon deposits from the spark arrester screen.
Note: The spark arrester must have no holes or cracks. Replace if necessary.
Refit the spark arrester, the exhaust silencer guard and the exhaust silencer in the reverse order to removal.
7.6. 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.
7.7. 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
In the event that the generating set is not to be used for a long period, it must be stored in accordance with the guidelines below.
Tilt the noise deflector (diag. A - no. 15) forwards.
Close the engine fuel tap (diag. A - no. 5), remove the sediment bowl (diag. C - no. 3) and empty it (see the Cleaning the sediment
bowl section).
Open the engine fuel tap and drain the fuel from the tank into a suitable container.
Refit the sediment bowl and tighten fully.
Drain the fuel by unscrewing the fuel drain plug (diag. C - no. 1). Collect the fuel in a suitable container.
Change the engine oil (see the Renewing the engine oil section).
Remove the spark plug (see the Checking the spark plug section) and pour a maximum of 15 ml of engine oil into the cylinder via
the orifice in the spark plug before refitting it.
Turn the engine over without starting it to distribute the oil in the cylinder.
Refit the noise deflector.
Clean the outside of the generating set, apply a rust protection product to the damaged sections and cover it with the protective
cover to protect it from dust.
Store the generating set in a clean, 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
is seated to compress the washer.
