3. Examine the hand guard for damages.
To do a check of the vibration damping system
WARNING: Use of incorrectly wound cord or
an incorrect cutting attachment increases
the level of vibration.
The vibration damping system decreases vibration in the
handles to a minimum which makes the operation
easier. The vibration damping system decreases the
vibrations between the engine unit and the shaft unit.
1. Stop the engine.
2. Do a visual check for deformation and damage, for
example cracks.
3. Make sure that the vibration damping units are
attached correctly.
To do a check of the muffler
1118 - 001 - 05.09.2019
The muffler keeps noise levels to a minimum and sends
exhaust fumes away from the operator.
• Do a visual check for damage and deformation.
• Make sure that the muffler is correctly attached to
the product.
• If the muffler on your product has a spark arrester
screen, do a visual check. Replace the spark
arrester screen if it is damaged.
a) Clean the spark arrester screen if it is blocked. A
blocked spark arrester screen causes the engine
to become too hot which causes damage to the
engine.
b) Make sure that the spark arrestor mesh is
attached correctly.
To do a check of the blades and blade guard
The outer part of the blades has the function of a blade
guard. The blade guard prevents cut injuries.
1. Stop the engine and make sure that the blades stop.
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, or a damaged blade guard.
5. Make sure that the screws to the blades and blade
guard are tight.
