SAFETY INSTRUCTIONS
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 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.
Cutter guard
(325HDA55)
•
Check that the blade guard is not damaged or distorted.
•
Replace the blade guard if it is bent or damaged.
Gear housing
•
The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear
housing.
