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.

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 should operate the socket 
spanner when loosening or tightening the nut.

The nylon lining inside the locking nut must not be so worn 
that you can turn it by hand. The lining should offer a 
resistance of at least 1.5 Nm. The nut should be replaced 
after it has been put on approx. 10 times.

The lock screw must be tightened securely for ball-bearing-
mounted support cups.
