Adjusting The Carburettor; Chain Brake - Gardenline PCH25 User Manual

Operating Instructions

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 (14
and 15) using screwdriver (26). Do not force. (Fig AB)
2. Turn the H screw (14) back 3/4 of a turn.
3. Turn the L screw (15) 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 (15) 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) (13) 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) (14) for best cutting power, not for maximum speed.
Note. It is preferred the above operation is performed by a service centre to
ensure the correct setting for both safety and performance is achieved.

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 (7) 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. (Fig AC)
2. To release the chain brake, pull the front guard towards the top handle until a
"click" is heard.
Hold the top handle (8) and pull back the front guard firmly by grasping the guard
on the right hand side and pulling back. This is a firm operation and will require
the operator to pull back firmly.
CAUTION.
chainsaw is used.
