1. Make sure that there are no cracks or deformation
on the vibration damping units. Replace the vibration
damping units if they are damaged.
2. Make sure that the vibration damping units are
correctly attached to the engine unit and handle unit.
Muffler
The muffler keeps the noise levels to a minimum and
sends the exhaust fumes away from the operator.
Do not use the product if the muffler is missing or
defective. A defective muffler increases the noise level
and the risk of fire.
WARNING: The muffler gets very hot during
and after use. This also applies during idling.
Be aware of the fire hazard, especially when
working near flammable substances and/or
vapours.
To examine the muffler
1. Make sure that the muffler is not damaged.
2. Make sure that the muffler is correctly attached.
Kickback
WARNING: Kickbacks are sudden and can
be very violent. The power cutter can be
thrown up and back towards the user in a
rotating motion causing serious or even fatal
injury. It is vital to understand what causes
kickback and how to avoid it before using
the product.
Kickback is the sudden upward motion that can occur if
the blade is pinched or stalled in the kickback zone.
Most kickbacks are small and pose little danger.
However a kickback can also be very violent and throw
the power cutter up and back towards the user in a
rotating motion causing serious or even fatal injury.
Reactive force
A reactive force is always present when cutting. The
force pulls the product in the opposite direction to the
blade rotation. Most of the time this force is insignificant.
If the blade is pinched or stalled the reactive force will be
10
strong and you might not be able to control the power
cutter.
Never move the product when the cutting equipment is
rotating. Gyroscopic forces can obstruct the intended
movement
Kickback zone
Never use the kickback zone of the blade for cutting. If
the blade is pinched or stalled in the kickback zone, the
reactive force will push the power cutter up and back
towards the user in a rotating motion causing serious or
even fatal injury.
