Replace the oil filter cartridge after the initial 50 hours of
operation and every 200 hours thereafter.
• Remove the old oil filter cartridge (2) with a filter
wrench.
• Apply a film of oil to the gasket for the new cartridge.
• Screw in the cartridge by hand. When the gasket con-
tacts the seal surface, tighten the cartridge enough
by hand. Because, if you tighten the cartridge with a
wrench, it will be tightened too much.
• After the new cartridge has been replaced, the engine
oil level normally decreases a little. Thus, run the
engine for a while and check for oil leaks through the
seal before checking the engine oil level. Add oil if
necessary.
Fuel filter cartridge replacement (picture 3)
• Replace the fuel filter cartridge (6) with a new one
every 400 operating hours.
• Apply fuel oil thinly over the gasket and tighten the
cartridge into position by hand-tightening only.
• Finally, vent the air.
Air bleeding the fuel system (picture 3)
Do not bleed a hot engine as this could
cause fuel to spill onto a hot exhaust
manifold creating a danger of fire.
Air bleeding of the fuel system is required if;
• After the fuel filter and pipes have been detached and
refitted.
• After the fuel tank has become empty.
• Before the engine is to be used after a long storage.
Procedure
Loosen air vent plug (5) of the fuel filter a few turns.
•
• Turning the starting key in "ON" position; the electric
• pump (7) started.
• Screw back the plug (5) when bubbles do not come
up any more.
• Turning the starting key in "OFF" position.
Replacing the fuel pre-filter (picture 3)
Replace the fuel pre-filter 1 every 50 hours.
• Loosen the two hose clamps using a flathead screw-
driver.
• Replace the filter (8), note flow direction.
• Tighten the two hose clamps.
• If necessary, repeat the bleeding operation as with
the fuel filter.
Changing coolant (picture 4)
To unload the coolant liquid to proceed like it follows:
• To open the coolant drain cock (9).
• To open the radiator cap (10). With the radiator cap
kept closed, a complete drain of water is impossible.
