Checking The Spark Plug; Storing The Generating Set; Fault Finding - SDMO ALIZE 3000 Manuel D'utilisation Et D'entretien

7.5. Checking the spark plug

Undo the four 10 mm bolts holding the closure panel in place exhaust end, and remove the panel.
Remove the spark plug cap and use a spark plug spanner to remove the spark plug.
Inspect the spark plug and discard it if the electrodes are worn or if the insulation is melted or chipped. If it is to be re-used, clean
the spark plug with a metallic 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 compress the washer.
Note: When fitting a new spark plug, tighten it by 1/2 turn after it is seated, in order to compress the washer. If refitting an old
spark plug, tighten it by a 1/8 –1/4 turn when it is position, in order to compress the washer.
Refit the closure panel exhaust end and ensure that it is held in place.
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. Ensure that the storage area is not dusty or humid. Clean the exterior of the generating set and
apply a rustproofing product.
Remove the closure panels exhaust end and starter end (10 mm bolts).
Open the fuel tap and drain the fuel from the tank into a suitable container.
Drain the carburettor by loosening the drain screw. Recover the fuel in a suitable container.
Change the motor oil.
Remove the spark plug and pour approximately 15 ml of oil into the cylinder, then refit the spark plug.
Refit the closure panels exhaust end and starter end.
Leave the motor running at several speeds to distribute the oil in the cylinder.
Clean the generating set and cover the motor to protect it from dust.
Store the generating set in a clean, dry place.
