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.
