Husqvarna K 4000 Cut-n-Break Manuel D'utilisation page 16

Cause of kickback
Kickback is caused if you are cutting with the kickback
zone of the blade for example when cutting "upwards" or
towards you.
General rules
• Never cut upwards or towards you so that the kickback
zone becomes actively cutting.
• 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.
• When cutting vertically, always cut from the top of the
cut and down.
• Always cut at maximum speed.
• Do not cut with the upper quadrant (kickback zone) of
the blade. Avoid twisting or pushing the blades
sideways in the cut. This can cause kickback.
• Take care when inserting the blade in an existing cut.
Make certain that the cut is wide enough and that the
blades are not angled in the cut. This can cause
kickback.
• Stand at a comfortable distance from the work piece.
• Never cut above shoulder height.

OPERATING
• Never cut from a ladder. Use a platform or scaffold if
the cut is 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.
Pull in
Pull in occurs when the blades' lower sections suddenly
stop or when the cut closes. (To avoid, see the
instructions under the heading "General rules" and
"Pinching/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.
Check the engine speed
Use a revolution counter regularly to check the engine
speed at the working temperature, at full throttle and
without a load.
