OPERATION (cont.)
16
Stopping the chainsaw
1. Release the throttle trigger (4).
2. Set the on/off switch (11) to Off (the O position).
Checking the chain bar 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. It may take 15-30
seconds for this to happen if this is the first time
the chainsaw has been started. If there is no line
of chain oil, stop the motor immediately and
investigate the cause. The chain bar 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
(clockwise) both the H and L needles
using screwdriver (16). Do not force.
2. Turn the H screw back (anti-clockwise)
3/4 of a turn.
3. Turn the L screw back (anti-clockwise)
1-1/2 turns.
4. Start the engine and let it warm up with the throttle trigger (4) half pulled in.
When the engine is warm, release the throttle trigger.
5. Turn the L screw 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) 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 (H) for best cutting power, not for maximum speed.
