GENERAL SAFETY PRECAUTIONS
English
–
51
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! 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!
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.
!
WARNING! Always stop the engine
before doing any work on the cutting
attachment. This continues to rotate even
after the throttle has been released.
Ensure that the cutting attachment has
stopped completely and disconnect the
spark plug cap before you start to work
on it.
