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.
 
Blade 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.
