SAFETY INSTRUCTIONS
• Check that the throttle control and throttle lock move freely
and that the return springs work properly.
• See instructions under the heading Start. Start the hedge
trimmer and apply full throttle. Release the throttle trigger
and check that the blades stop and remain stationary. If
the blades move when the throttle trigger is in the idle
position then the carburettor idle setting must be adjusted.
See instructions under the heading Maintenance.
Stop switch
• Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Hand guard
• Check that the hand guard is fitted correctly.
• Check that the hand guard is undamaged.
Vibration damping system
• Regularly check the vibration damping units for cracks or
deformation.
• Make sure the vibration damping units are securely
attached to the engine unit and handle unit.
Muffler
• 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. Never use a muffler that has a defective
spark arrestor mesh.
Blades
To ensure good cutting results it is important that the contact
pressure between the blades is correct. The contact pressure
is adjusted by turning the screws on the underside of the bar
clockwise as far as they will go. Then turn the screws
anticlockwise a 1/4 turn. Lock the screws using the locking nut
on the top of the bar. Check that the screws are loose enough
to allow the washers under the screw heads to slide sideways.
When the blades are correctly adjusted the play between the
blades should be 0,2–0,4 mm, measured at the screws. The
edges of the blades are too hard to be filed. Dull blades
should be sharpened using a grinder. Replace the blades if
they are bent or damaged.
