MACHINE´S SAFETY EQUIPMENT
General
This section describes the machine
s safety equipment, its 
purpose, and how checks and maintenance should be carried 
out to ensure that it operates correctly.
Throttle lockout
The throttle trigger lock is designed to prevent accidental 
operation of the throttle. When the lock (A) is pressed in this 
releases the throttle (B).
The trigger lock remains pressed in as long as the throttle is 
pressed. When the grip on the handle is released the throttle 
trigger and the throttle trigger lock both return to their original 
positions. This is controlled by two independent return spring 
systems. This means that the throttle trigger is automatically 
locked in the idle position.
Checking the throttle lockout
Make sure the throttle control is locked at the idle setting 
when the throttle lockout is released.
Press the throttle lockout and make sure it returns to its 
original position when you release it.
Check that the throttle control and throttle lockout move 
freely and that the return springs work properly.
Start the power cutter and apply full throttle. Release the 
throttle control and check that the cutting blade stops and 
remains stationary. If the cutting blade rotates when the 
throttle is in the idle position you should check the 
carburettor’s idle adjustment. See instructions in the 
section "Maintenance".
Stop switch
Use the stop switch to switch off the engine.
Checking the stop switch
Start the engine and make sure the engine stops when 
you move the stop switch to the stop setting.
Guard for the blade
This guard is fitted above the cutting blade and is designed to 
prevent parts of the blade or cutting fragments from being 
thrown towards the user.
Checking the blade guard
Check that the guard over the cutting blade is not cracked 
or damaged in any other way. Replace when damaged.
Check that the cutting blade is fitted correctly and does 
not show signs of damage. A damaged cutting blade can 
cause personal injury.
!
WARNING! Never use a machine that has 
faulty safety equipment! If your machine 
fails any of these checks contact your 
service agent to get it repaired.
The engine should be switched off, and the 
stop switch in STOP position.
!
WARNING! Always check that the guard is 
correctly fitted before starting the machine.
