In countries that have a warm and dry climate there is a 
significant risk of fire. We therefore fit certain mufflers with 
a spark arrestor screen. Check whether the muffler on 
your machine is fitted with this kind of screen.

For mufflers it is very important that you follow the 
instructions on checking, maintaining and servicing your 
machine.

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 screen this must be cleaned regularly. A blocked 
screen will cause the engine to overheat and may lead to 
serious damage.

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.

The blade guard (A) is intended to protect against any 
part of the body coming into contact with the blades (B).

Check that the blade guard is not damaged or distorted. 
Replace the blade guard if it is bent or damaged.
