Throttle lock
 
• Make sure the throttle control is locked at the idle setting 
when the throttle lock is released.
• Press the throttle lock and make sure it returns to its 
original position when you release it.
• Check that the throttle control and throttle lock move freely 
and that the return springs work properly.
• The throttle lock is designed to prevent accidental 
operation of the throttle control. When you press the lock 
(A) (i.e. when you grasp the handle) it releases the throttle 
control (B). When you release the handle the throttle 
control and the throttle lock both move back to their 
original positions. This movement is controlled by two 
independent return springs. This arrangement means that 
the throttle control is automatically locked at the idle 
setting.
• See instructions under the heading Start. Start the 
machine and apply full throttle. Release the throttle and 
check that the cutting attachment stops and remains at a 
standstill. If the cutting attachment rotates with the throttle 
in the idle position then the carburettor idle setting must be 
checked. See instructions under the heading 
Maintenance.
 
Stop switch
 
• Start the engine and make sure the engine stops when 
you move the stop switch to the stop setting.
 
Cutting attachment guard
 
• Ensure that the guard is undamaged and is not cracked.
• Replace the guard if it has been exposed to impact or is 
cracked.
• Always use the recommended guard for the cutting 
attachment you are using. See chapter on Technical data.
 
Vibration damping system
 
• Regularly check the vibration damping units for cracks or 
deformation.
