Quick release
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.
Muffler
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.
GENERAL SAFETY PRECAUTIONS
Regularly check that the muffler is securely attached to
the machine.
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!
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.) 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.
