To do a check of the hand guard
The hand guard prevents injuries from the blades.
1. Stop the engine.
2. Make sure that the hand guard is attached correctly.
3. Examine the hand guard for damages.
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.
To do a check of the muffler
WARNING: Do not use the product
if the muffler is missing or damaged. A
muffler that is damaged or missing increases
the noise level and the risk of fire. Keep
fire extinguishing tools near. Do not use
a product without, or with a broken, spark
arrestor mesh if you must have a spark
arrestor mesh in your area.
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.
