Blades

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.

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

•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.
