Maintenance Procedures - SDMO BOOSTER 2000 UK Maintenance Manual

7. Maintenance procedures

Stop the motor before carrying out any maintenance procedure.
To make allowances for any accidental spillage, switch off the motor ignition and disconnect
the spark plug cap(s). Only use original parts or equivalent. The use of spare parts of a different
quality can damage the generating set.
Warning
7.1. Cleaning the air filter (diagram H)
Never use petrol or flammable solvents for cleaning the air filter element as this could result in
a fire or explosion.
Danger
❶ Open the enclosure with a screwdriver
❷ Remove the air filter cover (1), then take out the elements and separate them. Carefully check if the elements
are not ripped and have no holes, replace them if they are damaged.
❸ Wash the foam element (2) with a household detergent diluted in warm water. Leave to dry fully.
❹ Gently tap the paper element several times (3). on a hard surface, to remove excess dirt. Never try to remove
dirt using a brush. This will just push the dirt into the fibres. Replace the paper element, if it is too dirty.
❺ Reinsert the air filter elements and refit the cover in the opposite order to removal.
❻ Close the enclosure.
7.2. Changing the engine oil (diagram I)
Change the oil when the engine is still hot, to ensure that drainage is rapid and complete.
❶ Open the enclosure with a screwdriver
❷ Remove the oil filler cap and drain plug, and drain the oil into a suitable container.
❸ When this is done, screw the drain plug back in tightly and then fill, with recommended oil, to upper marker
on the dipstick. (see paragraph 3.1).
❹ Check that there are no leaks
❺ Close the enclosure.
7.3. Testing the spark plug (diagram J)
❶ Remove the spark plug cap and use a spark plug wrench to remove the spark plug.
❷ Inspect each spark plug and discard any that have worn electrodes or melted or cracked insulation. If they are
to be re-used, clean the spark plugs with a metallic brush.
❸ Measure the space between the electrodes with a thickness gauge. The electrode gap should be from 0.6 à 0.7
mm. Check that the spark plug washer are in good condition and screw them in by hand, in order to avoid
damaging the threads.
❹ After inserting the spark plug, tighten it with a spark plug wrench to secure the washer.
Note: for the installation of a new spark, 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.
7.4. Checking nuts, bolts and screws
Daily, detailed checks of all nuts, bolts and screws are essential in order to prevent any accidents or breakdowns.
❶ Inspect the generating set as a whole before and after each use.
❷ Tighten any loose nuts or screws.
NB: the tightening of cylinder head bolts should be carried out by a specialist. Contact your local agent.
7.5. Cleaning the generating set
❶ 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 advised).
❷ Carefully clean the motor air inlets and outlets and the alternator.
❸ Check the general condition of the generating set and, if necessary, change any defective parts.
