a) Have your power tool serviced by a qualified
repair person using only identical replace-
ment parts. This will ensure that the safety of the
power tool is maintained.

Circular saw safety warnings

Safety instructions for all saws
а)
DANGER: Keep hands away from cut-
ting area and the blade. Keep your second
hand on auxiliary handle, or motor housing.
If both hands are holding the saw, they cannot be
cut by the blade.
b) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
c) Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
d) Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a sta-
ble platform. It is important to support the work
properly to minimize body exposure, blade binding,
or loss of control.
e) Hold the power tool by the insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden wir-
ing or its own cord. Contact with a "live" wire will
also make exposed metal parts of the power tool
"live" and could give the operator an electric shock.
f) When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware of
the saw will run eccentrically, causing loss of con-
trol.
h) Never use damaged or incorrect blade wash-
ers or bolt. The blade washers and bolt were spe-
cially designed for your saw, for optimum perfor-
mance and safety of operation.

Kickback causes and related warnings
▪ Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to
lift up and out of the workpiece 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 twisted 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.
Original instructions
Kickback is the result of saw misuse and/or incorrect op-
erating procedures or conditions and can be avoided by
taking proper precautions 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 kick-
back forces can be controlled by the operator, if
proper precautions are taken.
b) When blade is binding, or when interrupting
a cut for any reason, release the trigger and
hold the saw motionless in the material until
the blade comes to a complete stop. Never at-
tempt 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 cor-
rective actions to eliminate the cause of blade bind-
ing.
c) When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth 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. Unsharp-
ened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kick-
back.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Safety instructions for circular saws with outer pen-
dulum guard, circular saws with inner pendulum
guard , circular saws with tow guard
a) Check lower guard for proper closing before
each use. Do not operate the saw if lower guard
does not move freely and close instantly. Nev-
er clamp or tie the lower guard into the open
position. If saw is accidentally dropped, lower
guard may be bent. Raise the lower guard with the
retracting handle and make sure it moves freely
and does not touch the blade or any other part, in
all angles and depths of cut.
b) Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to dam-
aged parts, gummy deposits, or a build-up of de-
bris.
c) Lower guard may be retracted manually only
for special cuts such as "plunge cuts" and
"compound cuts". Raise lower guard by re-
tracting handle and as soon as blade enters
the material, the lower guard must be released.
For all other sawing, the lower guard should oper-
