Spark plug

The engine spark plug is hidden under the ignition
cable shoe. When performing service, it is important
that the engine cannot start accidentally. For this
reason, always remove the ignition cable shoe from
the spark plug. To avoid pulling the cable, the cable
shoe is equipped with a special handle; see the
illustration.
Type of spark plug, see chapter "Technical data".
Service instructions, see chapter "Maintenance/
Ignition system".

Muffler

The engine muffler is equipped with a heat protective
cowling. Nonetheless, it still becomes hot when the
engine is running. Avoid touching the muffler when it
is warm. Risk for burns.
Oil dipstick
The dipstick for the crankcase oil reservoir is located
on the front of the engine. Refill the engine oil in the
hole where the dipstick fits.
When checking the oil level, the dipstick should not
be screwed in. The machine should be parked on
even ground with the engine stopped. Never run the
engine without the dipstick in place. The engine has
an electronic oil level guard. It stops and cannot be
started if the level becomes too low. Yet you should
not rely entirely on the level guard; rather you should
check the oil using the dipstick.
For normal use, we recommend SAE 10W-30-weight
engine oil service SF-SG; see also the chapter
"Lubrication/Engine oil".
Oil drainage
The drainage screw for the crankcase oil reservoir is
located on the front of the engine.
IMPORTANT INFORMATION
Used engine oil is a health hazard and
legislation prohibits disposal on the ground
or in nature; it should always be disposed of
at a workshop or appropriate disposal location.
Avoid skin contact; wash with soap and water
in case of spills.

Engine switch

The engine switch stops the engine. The illustration
shows the switch in the OFF position (short circuited
electrical system). To start the engine, the switch
must be first set to the ON position.
