Safety instructions for all saws
Sawing method
a)
DANGER! Keeps your hands clear
of the sawing area and the saw
blade. Hold the auxiliary handle or
motor housing with your other hand.
When
both hands are being used to hold the saw,
neither can be injured by the saw blade.
b)
Do not grip the underside of the workpiece.
The blade guard cannot protect from the saw
blade underneath the workpiece.
c)
Set the cutting depth to match the thickness
of the workpiece.
The blade should not extend
more than one full tooth depth under the work-
piece.
d)
Never hold the workpiece to be sawn in your
hand or over your leg. Fasten the workpiece
on a stable working surface.
It is important to
fasten the workpiece securely to minimise the
danger of bodily contact, jamming of the saw
blade or loss of control.
e)
Hold the device by the insulated handles when
you are carrying out work during which the
cutting edge may come into contact with con-
cealed power cables or the tool’s own power
cable.
Contact with a live wire will cause the
metal parts of the tool to become live which can
lead to an electric shock.
f)
When making longitudinal cuts, always use
a guide rail or a straight edge guide.
This will
improve the accuracy of your cut and reduce the
likelihood of the saw blade jamming.
g)
Always use saw blades of the correct size
and with an appropriate central fi xing bore
(e.g. star-shaped or round).
Saw blades that
do not fi t the mounting components in the saw
will not run true and could lead to a loss of
control.
h)
Never use damaged or incorrect saw blade
washers or screws.
The saw blade washers
and screws have been specially designed to
provide optimum performance and operational
safety for your saw.

Kickback – causes and corresponding safety
instructions
▯
A kickback is a sudden reaction caused as a
result of the saw blade catching, jamming or
being falsely aligned that cause the saw to
jump up uncontrollably and out of the work-
piece in the direction of the operator;
▯
if the saw blade catches or jams in a narrowing
saw cut, the blade can no longer rotate and the
power of the motor throws the device back in
the direction of the operator;
▯
if the saw blade twists in the saw cut or becomes
misaligned, the teeth at the rear edge of the saw
blade can become caught in the surface of the
workpiece causing the saw blade to jump out
of the cut and the saw to jump backwards in the
direction of the operator.
A kickback is caused by incorrect use or misuse of
the saw. It can be avoided by observing the follow-
ing safety precautions.
a)
Hold the saw fi rmly in both hands and position
your arms such that they can absorb the force
of a kickback. Always stand to the side of the
saw blade and never in line with it.
If a kickback
occurs, the circular saw may jump backwards.
However, by using observing appropriate pre-
cautions, the operator can control the kickback
forces.
b)
If the saw blade jams or you stop working,
switch the saw off and hold it steadily in the
workpiece until the saw blade has completely
stopped turning. Never attempt to remove the
saw from the workpiece or pull it backwards
while the saw blade is still moving as this
could lead to a kickback.
Find out why the saw
blade has jammed and remove the problem.
c)
If you want to restart a saw that is still in the
workpiece, centre the saw blade in the cut
and check to ensure that the teeth are not
caught anywhere in the workpiece.
If the saw
blade catches it can jump backwards out of the
workpiece or cause a kickback when the saw
is restarted.
