7.5. Checking the spark plug (diagram G)
Remove the spark plug cap and use a spark plug spanner to remove the spark plug.
Visually inspect the spark plug and discard it if the electrodes are worn or if the insulation is split or chipped. If it is to be re-used,
clean the spark plug with a wire brush.
Measure the electrode gap with a feeler gauge. The electrode gap should be from 0.70 to 0.80 mm. Check that the spark plug
washer is in good condition and screw the spark plug in by hand, in order to avoid damaging the threads.
After fitting the spark plug, tighten it with a spark plug spanner to secure the washer.
Note: when fitting a new spark plug, tighten it by 1/2 turn after it is in place, in order to press the washer tightly. For the
installation of an old spark plug, tighten it by a 1/8–1/4 turn after it is in place, in order to press the washer tightly.
7.6. Checking bolts, nuts and screws
Daily, detailed checks of all nuts, bolts and screws are essential in order to prevent any accidents or breakdowns.
Inspect the generating set as a whole before and after each use.
Tighten any loose nuts or screws.
NB: the tightening of cylinder head bolts should be carried out by a specialist. Contact your local agent.
7.7. Cleaning the generating set
Remove all dust and debris from around the exhaust and clean the generating set using a cloth and a brush (cleaning with a water
jet is not recommended, and cleaning with high-pressure cleaning equipment is forbidden).
Carefully clean the motor air inlets and outlets and the alternator.
Check the general condition of the generating set and, if necessary, replace any faulty parts.
8. Storing the generating set
Generating sets which are to remain unused for a long period of time must undergo certain procedures, in order to keep them in good
condition. Check that the storage area is not dusty or humid. Clean the exterior of the generating set and apply rustproofing product.
Close the fuel tap (OFF position), remove the sediment bowl and drain it.
Open the fuel tap (ON position) and drain the petrol from the tank into a suitable container.
Refit the sediment bowl and tighten fully.
Drain the carburettor by loosening the drain screw. Collect the petrol in a suitable container.
Change the engine oil.
Remove the spark plug and pour about 15 ml of oil into the cylinder, then refit the spark plug.
Leave the engine to run for a few moments to distribute the oil in the cylinder.
Clean the generating set and cover the engine again to protect it from dust.
Store the generating set in a clean, dry place.
