There is an easily accessible, quick release fitted at the 
front as a safety precaution in case the engine catches 
fire, or in any other situation that requires you to free 
yourself from the machine and harness. See instructions 
under the heading Adjusting the harness and clearing 
saw.

Check that the harness straps are correctly positioned. 
Once the harness and machine have been adjusted, 
check that the harness quick release works correctly.

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

For mufflers it is very important that you follow the 
instructions on checking, maintaining and servicing your 
machine.

Never use a machine that has a faulty muffler.

Regularly check that the muffler is securely attached to 
the machine.

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.) Tighten the nut using the socket spanner.

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.
