Check that the harness straps are correctly positioned.

Muffl

The muffler is designed to keep noise levels to a minimum 
and to direct exhaust fumes away from the user. A muffler 
fitted with a catalytic converter is also designed to reduce 
harmful exhaust gases.
In countries that have a warm and dry climate there is a 
significant risk of fire. We therefore fit certain mufflers with 
a spark arrestor screen. Check whether the muffler on 
your machine is fitted with this kind of screen.
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.
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to 
the machine.
If the muffler on your machine is fitted with a spark 
arrestor screen this must be cleaned regularly. A blocked 
screen will cause the engine to overheat and may lead to 
serious damage.
Locking nut
A locking nut is used to secure some types of cutting 
attachment.
When fitting, tighten the nut in the opposite direction to the 
direction of rotation of the cutting attachment. To remove 
it, undo the nut in the same direction as the cutting 
attachment rotates. (CAUTION! The nut has a left-hand 
thread.) When loosening and tightening the saw blade 
nut, there is a risk of injury from the teeth of the saw blade. 
You should therefore always ensure that your hand is 
shielded by the blade guard when doing this. Always use 
a socket spanner with a shaft that is long enough to allow 
this. The arrow in the diagram shows the area where you

WARNING! Mufflers fitted with catalytic 
converters get very hot during use and 
remain so for some time after stopping. 
This also applies at idle speed. Contact 
can result in burns to the skin. 
Remember the risk of fire!
!
WARNING! The inside of the muffler 
contain chemicals that may be 
carcinogenic. Avoid contact with these 
elements in the event of a damaged 
muffler.
!
WARNING! Bear in mind that:
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!
