GENERAL SAFETY PRECAUTIONS
Cutting attachment guard
This guard is intended to prevent loose objects from being
thrown towards the operator. The guard also protects the
operator from accidental contact with the cutting
attachment.
Check that the guard is undamaged and not cracked.
Replace the guard if it has been exposed to impact or is
cracked.
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.
WARNING! Never use a cutting
!
attachment without an approved guard.
See the chapter on Technical data. If an
incorrect or faulty guard is fitted this can
cause serious personal injury.
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
Using incorrectly wound cord or a blunt or incorrect
cutting attachment (wrong type or incorrectly filed, see
instructions under the heading Filing the blade) increases
the level of vibration.
The machine's vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine's handle unit.
