GENERAL SAFETY PRECAUTIONS
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.
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.)
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.
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
• Reduce the risk of blade thrust.
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
!
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! 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!
IMPORTANT!
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
Refer to the instructions for the cutting attachment to check
the correct way to load the cord and the correct cord
diameter.
Keep the teeth of the blade correctly sharpened! Follow our
recommendations. Also refer to the instructions on the
blade packaging.
Maintain the correct blade setting! Follow our instructions
and use the recommended file gauge.
