GENERAL SAFETY PRECAUTIONS
For mufers 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 mufer.
Regularly check that the mufer is securely attached to the
machine.
If the mufer on your machine is tted 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.
Locking nut
A locking nut is used to secure some types of cutting
attachment.
When tting, 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.
Locking screw
The lock screw must be tightened securely for ball-bearing-
mounted support cups.
!
WARNING! Mufers tted 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
re!
!
WARNING! The inside of the mufer contain
chemicals that may be carcinogenic. Avoid
contact with these elements in the event of a
damaged mufer.
!
WARNING! Bear in mind that:
Engine exhaust fumes contain carbon
monoxide, which can cause carbon
monoxide poisoning. For this reason you
should not start or run the machine indoors,
or anywhere that is poorly ventilated.
The exhaust fumes from the engine are hot
and may contain sparks which can start a
re. Never start the machine indoors or near
combustible material!
