General Safety Instructions

� Before using the machine, carefully read all
safety instructions and the Operating Instruc-
tions.
� Keep all of the attached documents and pass
on the documentation if the machine changes
ownership.
Safety Rules for Circular Saws
a) Keep hands away from the cutting area
and the saw blade. Keep your second
hand on the auxiliary handle or the motor
housing. If both hands are holding the circular
saw, they can not be cut by the saw blade.
b) Do not reach underneath the work. The
blade guard can not protect you from the saw
blade below the work.
c) Adjust the depth-of-cut to the thickness of
the work. It should not be visible below the
work by more than the height of a full tooth.
d) Never hold the workpiece being cut in
your hand or across your leg. Secure the
work on a firm support. It is important to
secure the work properly to minimize the
danger of body exposure, blade binding or
loss of control.
e) Hold the power tool only by the insulated
gripping surfaces when performing an
operation where the cutting tool may run
into hidden wiring or its own cord. Contact
with a "live" wire will also make exposed metal
parts of the tool "live" and shock the operator.
f) Always use a ripping guide or straight
edge guide for length cuts. This improves
the precision of the cut and reduces the
possibility of blade binding.
g) Always use saw blades with the correct
size and the matching arbour shape
(diamond or round). Blades that do not
match the mounting hardware of the saw will
run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade
washers or screws. The blade washers and
screws were specially designed for your saw
for optimum performance and safety of ope-
ration.
Additional Safety Rules
for all Circular Saws
Cause and operator prevention of kickback:
� Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the work-
piece toward the operator;
� When the blade is pinched or bound tightly by
the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back
toward the operator;
� If the blade becomes twinsted or misaligned
in the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood
causing the blade to climb out of the kerf and
jump back toward the operator.
Kickback is the result of saw misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper pre-
cautions as given below.
a) Maintain a firm grip with both hands on
the saw and position your arms to resist
kickback forces. Position your body to
either side of the blade, but not in line
with the blade. Kickback could cause the
saw to jump backwards, but kickback forces
can be controlled by the operator, if proper
precautions are taken.
b) When blade is binding, or when interrupt-
ing a cut for any reason, release the trigger
and hold the saw motionless in the mate-
rial until the blade comes to a complete
stop. Never attempt to remove the saw
from the work or pull the saw backward
while the blade is in motion or kickback
may occur. Investigate and take corrective
actions to eliminate the cause of blade
binding.
c) When restarting a saw in the workpiece,
centre the saw blade in the kerf and check
that saw teeth are are not engaged into
the material. If saw blade is binding it may
walk up or kickback from the workpiece as
the saw is restarted.
d) Support large panels to minimise the risk
of blade pinching and kickback. Large
panels tend to sag under their own weight.
Supports must be placed under the panel on
both sides, near the line of cut and near the
edge of the panel.
e) Do not use dull or damaged blades. Un-
sharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding an kickback.
