Maintenance Procedures - SDMO BOOSTER 1000 UK Generating Set User And 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 (diagrams A and G)
Never use petrol or flammable solvents for cleaning the air filter element as this could result in a fire or
explosion.
Danger
❶ Open and remove the maintenance enclosure (No. 6, Diag A) using a screwdriver
❷ Remove the air filter cover (No. 1, Diag G), then remove the filter. Check to see if the filter is not torn or has holes, replace it if it
is damaged.
❸ Wash the foam element (No. 2, Diag G) with cleaning detergent diluted in warm water. Leave to dry fully.
❹ Reinsert the air filter element and refit the cover in the opposite order to removal.
❺ Close the enclosure.
7.2. Renewing the motor oil (diagrams A and H)
Change the oil when the engine is still warm, to ensure that drainage is rapid and complete.
❶ Open and remove the maintenance enclosures (No. 6, Diag A) and the drain port access cover (No. 17, Diag. A or No. 1,
Diag. H)
❷ Remove the oil filler cap (No. 2, Diag. H) and the drain plug (No. 3, Diag. H) 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 the upper limit on the dipstick. (see
paragraph 3.1).
❹ Check that there are no leaks
❺ Close the enclosures.
7.3. Checking the spark plug (diagrams A and I)
❶ Remove the spark plug enclosure (No. 18, Diag A) then the spark plug cap and use a spark plug spanner 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 0.6 to 0.7 mm. Check that the
washer for each spark plug is in good condition and screw in the spark plugs by hand to avoid damaging the threads.
❹ After inserting 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 in place, in order to compress the washers tightly. When fitting an
old spark plug, tighten it by a 1/8 –1/4 turn when in position, in order to compress the washer.
7.4. 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.
7.5. 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.
