Replacing The Fuel Filter; Cleaning The Air Filter; Checking The Spark Plug - SDMO neo 3000 Benutzer- Und Wartungshandbuch

7.4. Replacing the fuel filter

Danger
Close the fuel tap (fig. A – no. 3).
Observe the direction of fitting for the filter.
Release the fuel filter from its support bracket (fig. C – no. 4).
Remove the fuel pipes on either side of the filter and use a suitable container to collect the fuel.
Fit a new filter, observing the direction of fitting.
Open the fuel tap and check that there are no leaks.

7.5. Cleaning the air filter

Never use petrol or flammable solvents for cleaning the air filter element (risk of fire or explosion).
Important
Remove the inspection cover (fig. A – no. 2).
Remove the filter cover (fig. D – no. 1).
Remove the filter element (fig. D – no. 2) and check the type of clogging:
Dry clogging:
Use a low-pressure dry compressed air gun to blow from the inside of the filter element out, moving from the top to the bottom
until there is no more dust.
Check the condition of the filter element: replace it if it is at all damaged.
Refit the filter element and its cover.
Put back the inspection cover.
Moist/oily clogging:
Replace the filter element.
Refit the filter element and its cover.
Put back the inspection cover.

7.6. Checking the spark plug

Open the spark plug access cover (fig. E - no. 1), and fit the spark plug with the help of a plug spanner.
Check the condition of the spark plug (fig. E - no. 2) :
If the electrodes are worn or if the insulation is split or flaking:
Replace the spark plug.
Fit a new spark plug in position and tighten it by hand to
avoid damaging the threads.
Use a spark plug spanner to tighten the spark plug by 1/4-1/2
turn after it is seated to compress the washer.
7.7. Cleaning the generating set
Cleaning with a water jet is not recommended.
Cleaning with high pressure cleaning equipment is forbidden.
Important
Remove all dust and debris from around the exhaust.
Clean the generating set, particularly the alternator and engine air inlets and outlets, using a cloth and brush.
Check the general condition of the generating set and replace any faulty parts.
Do not smoke, or bring naked flames or generate sparks nearby. Check that there are no
leaks, wipe off any trace of fuel and ensure that the vapours have dissipated before
restarting the generating set.
Otherwise:
Clean the spark plug with a metal brush.
With a feeler gauge, check the electrode gap "X": it must be
between 0.6 and 0.8 mm inclusive.
Check the condition of the washer.
Fit the spark plug in position and tighten it by hand to avoid
damaging the threads.
Use a spark plug spanner to tighten it by 1/4-1/2 turn after it
