Vibration damping system
WARNING: Overexposure to vibration can
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
Such symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin color or condition.
These symptoms normally appear in the
fingers, hands or wrists. These symptoms
may be increased in cold temperatures.
Your product is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier. The product's vibration damping
system reduces the transfer of vibration between the
engine unit/cutting equipment and the product's handle
unit.
Cutting granite or hard concrete creates more vibration
than cutting soft concrete. Cutting with cutting
equipment that is blunt or faulty (wrong type or badly
sharpened) will increase the vibration level.
To do a check of the vibration damping system
WARNING: Make sure that the engine is
switched off and that the stop switch is in
STOP position.
