Chain catcher
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw.
Right hand guard
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks.
Vibration damping system
Regularly check the vibration damping units for cracks or
deformation.
Make sure the vibration damping units are securely
attached to the engine unit and handle unit.
Stop switch
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Muffler
Never use a machine that has a faulty muffler. Regularly
check that the muffler is securely attached to the
machine.
Note: The spark arrestor screen (A) on this machine is
serviceable. (48) The mesh must be replaced if it is
damaged. If the mesh is blocked the machine will
overheat and this will cause damage to the cylinder and
piston. Never use a machine with a muffler that is in poor
condition. Never use a muffler if the spark arrestor
mesh is missing or defective.
For normal homeowner use, the muffler and spark
arresting screen will not require replacement.
Air filter
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
•
Carburettor malfunctions
•
Starting problems
•
Loss of engine power
•
Unnecessary wear to engine parts.
•
Excessive fuel consumption.
•
Remove the air filter (3) after taking off the cylinder
cover, screw (1) and filter cover (2). When refitting
make sure that the air filter seals tightly against the
filter holder. Clean the filter by brushing or shaking it.
(49)
The filter can be cleaned more thoroughly by washing it
in water and detergent.
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.

MAINTENANCE
Spark plug
The spark plug condition is influenced by:
•
Incorrect carburettor adjustment.
•
An incorrect fuel mixture (too much or incorrect type
of oil).
•
A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating 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 0.5 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary. (50)
Note! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.
