11.When ready to start cutting, release the brake, by pulling the front guard back.

Stopping the chainsaw

1.Release the trigger switch.

2.Set the on/off switch (18) 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

 

 

 

 

 

 

 

 

L

T

H

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 (15) using screwdriver (28). Do not force.

2.Turn the H screw (15) back 3/4 of a turn.

3.Turn the L screw (16) 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) (14) 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 (15) 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 (8) 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 chainsaw is used.

Bucking spikes

The Chainsaw has bucking spikes (6) to assist with cutting and reduce the chance of kickback, use them as follows:
