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.

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.

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.

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 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.

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.

Avoiding kickback is simple.

•

The work piece must always be supported so that the cut 
stays open when cutting through. When the cut opens 
there is no kickback. If the cut closes and pinches the 
blade ther is always a risk of kickback.

•

Take care when inserting the blade in an existing cut.

•

Be alert to movement of the work piece or anything else 
that can occur, which could cause the cut to close and 
pinch the blade.

•

Secure the equipment during transportation in order to 
avoid transport damage and accidents.

•

For transport and storage of cutting blades, see the 
section "Cutting blades".

•

For transport and storage of fuel, see the section "Fuel 
handling".

•

Store the equipment in a lockable area so that it is out of 
reach of children and unauthorized persons.
