GENERAL SAFETY PRECAUTIONS
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 mesh. Check whether the muffler on your
machine is fitted with this kind of mesh.
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.
If the muffler on your machine is fitted with a spark arrestor
mesh this must be cleaned regularly. A blocked mesh will
cause the engine to overheat and may lead to serious
damage.
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!
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.
