Kickback
The word kickback is used to describe the sudden reaction
that causes the power cutter and cutting blade to be thrown
from an object when the upper quadrant of the blade, known
as the kickback zone, touches an object.
General rules
Kickback only occurs when the cutting blades kickback zone
touches an object.
•
Never use the kickback zone of the blade for cutting.
•
Keep a good balance and a firm foothold. Stand at a
comfortable distance from the work piece.
•
Always cut at maximum speed.
•
Take care when inserting the blade in an existing cut.
Never cut in a narrower pre-cut cut.
•
Never cut above shoulder height.
•
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.
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.
How to aviod 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.
Transport and storage
•
Secure the equipment during transportation in order to
avoid transport damage and accidents.
•
For transport and storage of Blades, see the section
"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.
!
WARNING! Kickback can happen very
suddenly and violently; kicking the power
cutter and cutting blade back at the user. If
this happens when the cutting blade is
moving it can cause very serious, even fatal
injuries. It is vital you understand what
causes kickback and that you can avoid it by
taking care and using the right working
technique.
