Safety instructions for manual
circular saws
Cutting procedures
a)
DANGER: Keep hands away from cutting
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 stable
platform. It is important to support the work proper-
ly to minimize body exposure, blade binding, or loss
of control.
e) Hold the power tool by insulated gripping
surfaces only, 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.
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 control.
h) Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance 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.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avo-
ided 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 kickback
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 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 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. Unsharpen-
ed or improperly set blades produce narrow kerf cau-
sing excessive friction, blade binding and kickback.
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.
Lower guard function
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. Never
clamp or tie the lower guard into the open po-
sition. If saw is accidentally dropped, lower guard
may be bent. Raise the lower guard with the retrac-
ting 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 damaged parts,
gummy deposits, or a build-up of debris.
c) Lower guard may be retracted manually
only for special cuts such as „plunge cuts" and
„compound cuts". Raise lower guard by retracting
handle and as soon as blade enters the material, the
lower guard must be released. For all other sawing,
the lower guard should operate automatically.
