To do a check of the vibration damping system
The vibration damping system decreases vibration in the
handles. The vibration damping units operate as a
separation between the product body and the handle
unit.
1. Do a visual check for deformation and damage.
2. Make sure that the vibration damping units are
correctly attached. (Fig. 16)
To do a check of the muffler
WARNING: Do not operate the product
without a muffler or a defective muffler. A
defective muffler can increase the noise
level and the risk of fire. Do not use the
product without, or with a broken, spark
arrester screen. The spark arrester screen
must be replaced if it is damaged.
WARNING: The mufflers become very hot
during and after operation, also at idle
speed.
CAUTION: If the spark arrester screen is
frequently blocked it can be a sign that
performance of the catalytic converter is
decreased. Turn to your servicing dealer to
examine the muffler. A blocked spark
arrester screen will cause overheating and
result in damage to the cylinder and piston.
WARNING: The inner surfaces of the muffler
contain chemicals that can cause cancer. Be
careful not to touch these elements if the
muffler is damaged.
The muffler keeps the noise levels to a minimum and
points the exhaust fumes away from the operator. A
muffler with a catalytic converter decrease harmful
exhaust gases.
1. Stop the engine.
2. Do a visual check for damage and deformation.
3. Make sure that the muffler is correctly attached to
the product.
4. Clean the spark arrester screen with a wire brush.

To do a check of the blade and blade guard
The outer part of the blades (A) has the function as
blade guards. The blade guard protects the operator
from accidental contact with the blade.
(Fig. 18)
1. Stop the engine and make sure that the cutting unit
stops.
2. Remove the spark plug cap from the spark plug.

3. Put on protective gloves.
4. Make sure that the blade and blade guard is not
damaged or bent. Always replace a damaged or
bent blade.
5. Make sure that the screws on the cutting unit are
attached. Torque the screws to 7-10 Nm. (Fig. 19)
