MAINTENANCE
Two--piece shaft
The drive shaft end in the lower shaft
should be lubricated with grease every 30
hours. There is a risk that the drive shaft
ends (splined coupling) will seize if they
are not lubricated regularly .
W ARNING: The inside of the
muffler contain chemicals that may
be c arcinoge nic. Avoid c ontact with
these elements in the event of a
damage d m uffler.
W ARNING: Bear in mind that:
Engine exhaust fumes contain car-
bon m onoxide, which can cause
carbon monoxide poison ing. For
this reason you should not start or
run the machine i ndoors, or any-
where that is poorly ve ntilate d.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the m achine indoors or n ear c om-
bustible material!
Spark plug
The spark plug condition is influenced by:
S Incorrect carburetor adjustment.
S An incorrect fuel mixture (too m uch or in-
correct type of oil).
S A dirty air filter.
These factors cause deposits on the spark
plug electrodes, which may result in operat-
ing problems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always
check the spark plug first b efore taking
any further action. If the spark plug is dirty ,
clean it and check that the electrode gap is
0,6 mm. The spark plug should be replaced
after about a month in operation or earlier if
necessary.
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder .

Air filter
The air filter must be regularly cleaned to
remove dust and dirt in order to avoid:
S Carburetor malfunctions
S Starting problems
S Loss of engine power
S Unnecessary wear to engine parts
S Excessive fuel consumption
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.
Cleaning the air filter
Remo ve the air fi lte r co ver and ta ke o ut the
