• Feed down the machine in line with the blade. Pressure
from the side can damage the blade and is very
dangerous.
• Move the blade slowly forwards and backwards to achieve
a small contact area between the blade and the material
to be cut. This reduces the temperature of the blade and
ensures effective cutting.
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 machine.
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 machine 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 strong and you
might not be able to control the power cutter.

OPERATING
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.
Climbing kickback
If the kickback zone is used for cutting the reactive force
drives the blade to climb up in the cut. Do not use the
kickback zone. Use the lower quadrant of the blade to avoid
climbing kickback.
Pinching kickback
Pinching is when the cut closes and pinches the blade. If the
blade is pinched or stalled the reactive force will be strong and
you might not be able to control the power cutter.
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.
Pipe cutting and pinching
Special care should be taken whet cutting in pipes. If the pipe
is not properly supported and the cut kept open through out
the cut the blade might be pinched in the kickback zone and
cause a severe kickback.
