Throttle trigger lockout
•
Make sure the throttle control is locked at the idle
setting when the throttle lockout is released.
•
Press the throttle lockout and make sure it returns to
its original position when you release it.
•
Check that the throttle trigger and throttle lockout
move freely and that the return springs work properly.
•
Start the chain saw and apply full throttle. Release the
throttle control and check that the chain stops and
remains stationary. If the chain rotates when the
throttle control is in the idle position you should check
the carburettor idle adjustment.
Chain catcher
Check that the chain catcher is in place and not damaged.
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. 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. (6)
After 75 hours of use, we recommend that your muffler be
replaced by your servicing dealer (retailer).
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.

MAINTENANCE
To clean the air filter: (34)
1
Remove the knob (A) holding the cylinder cover and
remove the cylinder cover (B).
2
Remove the air filter (D).
3
Clean the air filter.
- Wash the filter in clean, warm soapy water.
- Rinse in clean, cool water.
- Air dry completely.
4
Reassemble in reverse order. Make sure latch (E),
latch (F) and cylinder cover fit properly. Tighten the
knob securely.
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.
NOTE! It is advisable to have a supply of spare filters.
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 0,6 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary. (36)
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.
