•
Do not touch muffler or exhaust pipes while they are hot;
Severe burns could result.
• Allow the engine to cool down sufficiently, especially before
changing the oil or the oil filter cartridge. Oil can be hot and
cause burns.
• Contact with engine oil can damage your skin. Put on gloves
when using engine oil. If you come in contact with engine
oil, wash it off immediately.
•
When changing engine oil, dispose it according to local
regulations.
•
When cleaning any parts, do not use gasoline but use
regular cleanser.
•
Always use proper tools, that are in good condition. Make
sure you understand how to use them, before performing
any service work.
• Be sure to tighten all bolts lest they should be loose. Tighten
the bolts by the specified torque.
•
Do not put any tools on the battery, or battery terminals
may short out. Severe burns or fire could result. Detach the
battery from the engine before maintenance.

Servicing after break-in

•
Change engine oil and replace the oil filter (refer to 5.4.3).
•
Check and tighten nuts, bolts, and unions, paying particular
attention to the fuel system and using the torque chart
below.

Size M6x1.0
Nm* 10.8+1.0
* Apply 80% torque when tightening bolts to
aluminium alloy.
•
Observe the exhaust at the normal full load. The exhaust
must be free from soot. Do not allow the engine to run with
a dirty exhaust without investigating the cause as this may
result in an expensive breakdown. When ramping up RPM
the engine will probably produce some smoke. After
stabilizing on the right RPM for the load the exhaust should
be free from soot.
•
Check the electrical connections.

Changing engine oil and oil filter cartridge

1 Run the engine until it is on temperature, stop it and let it
cool down sufficiently to allow safe working.
2 Drain oil through the dipstick hole using a vacuum pump as
commonly used in garages.
3 Put some tissues under the oil filter cartridge.
4 Remove the old cartridge with a filter wrench.
5 Apply a film of oil to the gasket for the new cartridge.
6 Screw in the cartridge by hand. When the gasket contacts
the seal surface, tighten the cartridge not too firmly, by
hand.

7 Remove the oil filler cap on top of the engine, refill the
engine with oil (refer to 3.1.11 for specifications and
quantity). Allow the oil to come down to the oil pan and
check the oil level.
8 The oil level should be as close as possible to the maximum
level. Add (or drain) oil as necessary.
NOTE: When the genverter runs less than 200 hours a year, the
oil should be changed yearly.

Checking the battery

•
Check battery terminals for corrosion
•
Check the battery acid level (not applicable when sealed
batteries are used).
5.4.5

Adjusting the V-belt tension

Before adjusting belt tension, inspect the belt for glazing, cracks,
or dryness. A worn or damaged belt should be replaced.
1 Apply moderate thumb pressure to the belt between the
pulleys. When the belt is pressed in the middle of the span,
the deflection should be between 7 mm and 9 mm.
2 If the tension is incorrect, loosen the alternator mounting
bolts and, using a lever placed between the alternator and
the engine block, pull the alternator out until the deflection
of the belt falls within acceptable limits, then tighten the
alternator mounting bolts.

Draining water from the fuel tank

NOTE: This procedure is unusual on mobile installations.
It is included for completeness.
When handling fuel, make sure there are no open
flames or other fire hazards near the engine. Wipe
off any spilled fuel completely. Spilled fuel can
ignite and cause fire.
