Muffler bolts
Spark arrestor mesh
CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.
CAUTION:
Mufflers fitted with cata-
lytic converters get very hot during use
and remain so for some time after stop-
ping. This also applies at idle speed. Con-
tact can result in burns to the skin. Re-
member the risk of fire!
WARNING:
The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact
with these elements in the event of
a damaged muffler.
WARNING:
Engine exhaust
fumes contain carbon monoxide,
which can cause carbon monoxide
poisoning. DO NOT start or run the
machine indoors, or anywhere that
is poorly ventilated. The exhaust
fumes from the engine are hot and
may contain sparks which can start
a fire. Never start the machine in-
doors or near combustible material!

Spark plug

The spark plug condition is influenced by:
S Incorrect carburetor adjustment.
S An incorrect fuel mixture (too much 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 before taking
any further action. If the spark plug is dirty,
clean it and check that the electrode gap is
0.024" (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.

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.

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

Remove the air filter cover and take out the
filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals. A damaged air
filter must always be replaced.
