STARTING AND STOPPING

Starting and stopping

WARNING! Note the following before

!starting:

The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting.

Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries.

Place the machine on firm ground. Make sure you have a secure footing and that the chain cannot touch anything.

Keep people and animals well away from the working area.

Cold engine

Starting: The chain brake must be engaged when the chain saw is started. Activate the brake by moving the front hand guard forwards.

Ignition; choke (A): Set the choke control in the choke position. This should automatically set the stop switch to the start position.

Start throttle: The correct choke/start throttle setting is obtained by moving the control to the choke position.

Air purge (B): Press the air purge repeatedly until fuel begins to fill the bulb. The bulb need not be completely filled.

B

A

Decompression valve (C): Press the valve to reduce the pressure in the cylinder and make starting easier.You should always use the decompression valve when starting the machine. Once the machine has started the valve will automatically return to its original setting.

C

Warm engine

Use the same procedure as for starting a cold engine but without setting the choke control in the choke position. The correct choke/start throttle setting is obtained by moving the choke control to the choke position and then pushing it in again.

Starting

Grip the front handle with your left hand. Hold the chain saw on the ground by placing your right foot through the rear handle. Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull firmly and rapidly. Never twist the starter cord around your hand.

As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by quickly disengaging the throttle lock. This prevents unnecessary wear to the clutch, clutch drum and brake band.

Push in the choke control as soon as the engine fires and keep pulling until the engine starts. When the engine starts, quickly apply full throttle; the throttle start lock will automatically disengage.

CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.
