General

WARNING! Never use a machine that has
!
faulty safety equipment! If your machine
fails any checks contact your service
agent to get it repaired.
The engine should be switched off, and
the stop switch in STOP position.
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 trigger 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 trigger and throttle lockout
move freely and that the return springs work properly.

• Start the diamond chain saw and apply full throttle.
Release the throttle control and check that the chain
stops and remains stationary. If the chain rotates
when the throttle control 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.

Hand guard

WARNING! Always check that the guard
!
is correctly fitted before starting the
machine.
The hand guard prevents hands from coming into contact
with the moving cutting chain, for example, if the operator
loses grip on the front handle.
• Check that the hand guard is not damaged. Replace
the guard if damaged.
