STARTING AND STOPPING

Starting and stopping

Starting a cold engine

Ignition:

 Slide the ignition switch to the left.

Choke:

 Pull the choke control fully out.

Start throttle lock:

 Press in the throttle trigger lock, throttle 

control and then the start throttle lock (A). Release the throttle 
control and it is locked in the half throttle position. The lock 
releases when the throttle control is pressed in fully.

Automatic decompression valve

The machine is equipped with an automatic decompression 
valve to facilitate the start of the power cutter.

Starting a warm engine

Use the same starting procedure as for a cold engine but 
without setting the choke control in the choke position.

Starting

Grip the front handle with your left hand. Put your right foot on 
the lower section of the rear handle pressing the machine 
against the ground. 

Never twist the starter cord around 

your hand.

Grip the starter handle, slowly pull out the cord with your right 
hand until you feel some resistance (the starter pawls grip), 
now quickly and powerfully pull the cord.

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.

When the engine starts, quickly apply full throttle to 
automatically disengage fast idle.

Stopping

The engine is stopped by switching the ignition off using the 
stop switch.

!

WARNING! Note the following before 
starting:

Do not start the power cutter without the belt 
guard fitted. Otherwise the clutch could 
come loose and cause personal injuries.

Always move the machine away from the 
refuelling area before starting.

Ensure that you and the machine have a 
good working stance and that the cutting 
blade can rotate freely.

Keep people and animals well away from the 
working area.

!

WARNING! The cutting blade rotates when 
the engine is started. Make sure it can rotate 
freely.
