How to avoid kickback
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.
What is 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
• Never start to cut with the upper quadrant of the blade
as shown in the figure, also known as the kickback
zone.
• Always hold the machine in a firm grip with both
hands. Hold it so that the thumbs and fingers grip
round the handles.
• Keep a good balance and a firm foothold.
• Always cut at maximum speed.
• Stand at a comfortable distance from the work piece.
• Take care when inserting the blade in an existing 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.

SAFETY INSTRUCTIONS
Pull in
Pull in occurs when the disc's lower section suddenly
stops or when the cut closes. (To avoid, see the heading
"Basic rules" and "Jamming/rotation", here below.)
Pinching/rotation
If the cut is pressed together this can lead to jamming.
The machine can be pulled down suddenly with a very
powerful jerk.
How to avoid pinching
Support the work piece in such a way that the cut remains
open during the cutting operation and when the cut is
finished.
