OPERATING
•
First make the lower horizontal cut. Now make the two
vertical cuts. Finish with the upper horizontal cut. The risk
of jamming is then avoided.
•
When cutting out large holes it is important that the piece
to be cut out is braced so that it cannot fall against the
operator.
Kickback
The word kickback is used to describe the sudden reaction
that causes the machine and cutting equipment to be thrown
from an object when the upper quadrant of the bar, known as
the kickback zone, touches an object.
General rules
•
Kickback only occurs if the kickback zone of the bar
touches an object. Take care when using your saw and
make sure the kickback zone of the bar never touches any
object.
•
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 cutting equipment.
Pinching kickback
Pinching is when the cut closes and pinches the cutting
equipment. If the cutting equipment is pinched or stalled the
reactive force will be strong and you might not be able to
control the machine.
If the cutting equipment is pinched or stalled in the kickback
zone, the reactive force will push the machine 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
cutting equipment 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 cutting equipment.
!
WARNING! Kickback can happen very
suddenly and violently; kicking the machine
and cutting equipment back at the user. If
this happens when the cutting equipment 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.
