Stopping the chainsaw
1. Release the trigger switch.
2. Set the on/off switch (19) to
Off (the O position).
Checking the oil supply
Run the engine at medium
speed and check that the chain
splatters a thin line of oil which
can be seen on the ground when
the bar is pointed downwards.
This is normal. If there is no
line of chain oil, stop the motor
immediately and investigate the
cause. The oil tank could be
empty or the oil supply to the
chain blocked. This may require
removal of the bar and checking
that the upper oil hole in the bar
is clear of any blockages.
Adjusting the carburettor
The carburettor is factory set and
should not require adjustment.
Changes in operating conditions
may require fine tuning of the
carburettor. Proceed as follows.
1. Stop the engine and screw in
both the H and L needles (16
and 17) using screwdriver (29).
Do not force.
2. Turn the H screw (16) back 3/4 of a turn.
3. Turn the L screw (17) back 1-1/2 turns.
4. Start the engine and let it warm up with the trigger switch
half pulled in. When the engine is warm, release the
trigger switch.
5. Turn the L screw (17) slowly clockwise until the idling
speed is at its maximum then turn the screw back
(anticlockwise) 1/4 of a turn.
6. Turn the idling adjusting screw (T) (15) anticlockwise until
the chain does not turn.
7. If the idling speed is too slow, turn screw (T) clockwise.
8. Make a test cut and adjust screw (16) for best cutting
power, not for maximum speed.
Chain Brake
The chain brake operates automatically in the event of
kickback. As the guide bar (1) kicks up, the wrist of the
operator’s hand on the top handle knocks against the front
guard (9) causing the front guard to move forward and
activating the chain brake.
1. The chain brake can be
operated manually by moving
the front guard forward.
2. To release the chain brake,
pull the front guard towards
the top handle until a “click”
is heard.
CAUTION
. Check that the chain brake is operating correctly
each time the chain saw is used.
Bucking spikes
The Chainsaw has bucking spikes to assist with cutting
and reduce the chance of kickback, use them as follows:
1. Fit the bucking spike in the bark at point A.
2. Using point A as a pivot point lift
the rear of the chainsaw so the
chain enters the wood to be cut.
3. Pivot and repeat the operation
until the trunk has been cut
completely.
4. Use the central part of the
bar and never the tip for
cutting purposes.
