SAFETY INSTRUCTIONS
Vibration damping system
• Regularly check the vibration damping units for cracks or
deformation.
• Check that the vibration damping element is undamaged
and securely attached.
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 then it should be cleaned regularly. A blocked mesh
causes the engine to overheat, which can lead to serious
damage.
Never use a muffler with 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.
