s safety equipment

 

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. See the ”What is 
what?” section to locate where this equipment is positioned 
on your machine.

 

Vibration damping system

 

Your machine is equipped with a vibration damping system 
that is designed to minimize vibration and make operation 
easier.

The machine

 

 

s vibration damping system reduces the transfer 

of vibration between the engine unit/cutting equipment and 
the machine

 

 

s handle unit.

The engine body, including the cutting equipment, is insulated 
from the handles by vibration damping units.

 

Stop switch

 

Use the stop switch to switch off the engine.

 

Muffler

 

The muffler is designed to keep noise levels to a minimum 
and to direct exhaust fumes away from the user.

 

Throttle lock

 

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.

 

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.

!

 

WARNING! Never use a machine that has 
faulty safety equipment! Carry out the 
inspection, maintenance and service 
routines listed in this section.

!

 

WARNING! The muffler gets very hot in use 
and remains so for a short time afterwards. 
Do not touch the muffler if it is hot!

!

 

WARNING! The exhaust fumes from the 
engine are hot and may contain sparks 
which can start a fire. Never start the 
machine indoors or near combustible 
material!

 

IMPORTANT INFORMATION

 

For mufflers it is very important that you follow the 
instructions on checking, maintaining and servicing your 
machine. See instructions under the heading Checking, 
maintaining and servicing the machine’s safety equipment.

!

 

WARNING! The inside of the muffler contain 
chemicals that may be carcinogenic. Avoid 
contact with these elements in the event of a 
damaged muffler.
