7.4. Cleaning the spark arrester (diagram K)
Never use petrol or flammable solvents for cleaning the air filter element as this could result in a fire or explosion.
Danger
Loosen the two nuts (1) by 12 mm and remove the cylinder silencer (2).
Loosen by 5 mm the five bolts (3) and (4) holding the silencer guard (5) and then remove silencer guard.
Withdraw by 4 mm the bolt (6) attaching the spark arrester (7) and remove the spark arrester.
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 (7), the guard (5) and the silencer (2) in the reverse order to removal.
7.5. Cleaning the fuel filter (figure A)
Move the noise reducing deflector (No 23, fig A) forwards.
Close the fuel tap (No. 3, fig. A), pull out the sediment bowl then empty it
Open the fuel tap and drain the fuel into a suitable container
Detach the fuel supply pipes (tap end)
Remove the fuel tap complete with its filter
Remove and clean the low-pressure air injection filter
Refit the filter to the fuel tap then refit and tighten the fuel tap
Refit the fuel pipes
Refit then tighten the sediment bowl
Open the fuel tap and check that there are no leaks from the fuel tap or sediment bowl.
Move the noise reducing deflector (No 23, fig A) back to its initial position.
7.6. Checking the spark plug (diagram E)
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.
7.7. Starter battery maintenance
Never place the battery close to a flame or fire
Use only insulated tools
Never use sulphuric acid or acid water to top up the electrolyte level.
Danger
Check the electrolyte level and top up if necessary (only use de-ionised water)
Check the charge status using an acidimeter and recharge if necessary.
7.8. 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.
7.9. 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.
