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.

Starting

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

Cold engine

Start position (1): Set the start/stop switch in the choke position by pulling the red control outward - upward (1).

Decompression valve (2): Press the valve to reduce the pressure in the cylinder and make starting easier. Once the machine has started the valve will automatically return to its original setting.

Air purge (3): Press the air purge diaphragm repeatedly until fuel fills the diaphragm (at least 6 times). The diaphragm need not be completely filled.

Push down the red choke control (5) as soon as the engine fires which can be heard through a "puff" sound. Keep on pulling the cord powerfully until the engine starts.

Warm engine

When the chain saw is heated restart the saw only by pulling the cord powerfully until the engine starts (6).

Never twist the starter cord around your hand.

There is a simplified start reminder with illustrations to describe each step on the rear edge of the saw (A).

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 disengaging the throttle lock. Disengagement is done by gently touching on the throttle trigger. This prevents unnecessary wear to the clutch, clutch drum and brake band.

Allow the machine to idle a few seconds before giving full throttle.

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.

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 until the engine fires (4).
