Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Safety instructions for circular saws
Cutting procedures
DANGER: Keep hands away from cutting area and
u
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.
Do not reach underneath the workpiece. The guard
u
cannot protect you from the blade below the workpiece.
Adjust the cutting depth to the thickness of the work-
u
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.
Never hold the workpiece in your hands or across your
u
leg while cutting. Secure the workpiece to a stable
platform. It is important to support the work properly to
minimise body exposure, blade binding, or loss of con-
trol.
Hold the power tool by insulated gripping surfaces,
u
when performing an operation where the cutting tool
may contact hidden wiring 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.
When ripping always use a rip fence or straight edge
u
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
Always use blades with correct size and shape (dia-
u
mond versus round) of arbour holes. Blades that do not
match the mounting hardware of the saw will run off-
centre, causing loss of control.
Never use damaged or incorrect blade washers or
u
bolt. The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of op-
eration.
Kickback causes and related warnings
- kickback is a sudden reaction to a pinched, jammed or mis-
aligned saw blade, causing an uncontrolled saw to lift up and
out of the workpiece toward the operator;
- when the blade is pinched or jammed 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 sur-
face 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 operat-
ing procedures or conditions and can be avoided by taking
proper precautions as given below.
Maintain a firm grip with both hands on the saw and
u
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.
When blade is binding, or when interrupting a cut for
u
any reason, release the trigger and hold the saw mo-
tionless in the material until the blade comes to a com-
plete 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 cor-
rective actions to eliminate the cause of blade binding.
When restarting a saw in the workpiece, centre the
u
saw blade in the kerf so that the saw teeth are not en-
gaged into the material. If a saw blade binds, it may walk
up or kickback from the workpiece as the saw is restar-
ted.
Support large panels to minimise the risk of blade
u
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.
Do not use dull or damaged blades. Unsharpened or im-
u
properly set blades produce narrow kerf causing excess-
ive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must
u
be tight and secure before making the cut. If blade ad-
justment shifts while cutting, it may cause binding and
kickback.
Use extra caution when sawing into existing walls or
u
other blind areas. The protruding blade may cut objects
that can cause kickback.
Guard function
Check the guard for proper closing before each use.
u
Do not operate the saw if the guard does not move
freely and enclose the blade instantly. Never clamp or
tie the guard so that the blade is exposed. If the saw is
accidentally dropped, the guard may be bent. Check to
make sure that the guard moves freely and does not touch
the blade or any other part, in all angles and depths of
cut.
Check the operation and condition of the guard return
u
spring. If the guard and the spring are not operating
properly, they must be serviced before use.The guard
may operate sluggishly due to damaged parts, gummy de-
posits, or a build-up of debris.
Assure that the base plate of the saw will not shift
u
while performing a "plunge cut". Blade shifting side-
ways will cause binding and likely kick back.
Always observe that the guard is covering the blade
u
before placing the saw down on bench or floor. An un-
protected, coasting blade will cause the saw to walk back-
wards, cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is released.
Additional safety warnings
Do not allow the chip ejector to come into contact with
u
your hands. You may be injured by rotating parts.
