Safety instructions for circular saws
Cutting procedures
DANGER: Keep hands away from
cutting area and the blade. If both
hands are holding the saw, they cannot be cut by
the blade.
Do not reach underneath the
workpiece. The guard cannot protect you
from the blade below the workpiece.
Adjust the cutting depth to the
thickness of the work-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 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 control.
Hold the power tool by insulated
gripping surfaces, when performing an
operation where the cutting tool may
contact hidden wiring. 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 guide. This improves the
accuracy of cut and reduces the chance of blade
binding.
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 off-
centre, causing loss of control.
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,
jammed 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 jammed tightly
by the kerf closing down, the blade stalls and
the motor reaction drives the unit rapidly back
toward the operator;
EN
4
-
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 avoided by taking proper precautions as
given below.
Maintain a firm grip 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.
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.
When restarting a saw in the workpiece,
centre the saw blade in the kerf so that
the saw teeth are not engaged into the
material. If a saw blade binds, it may walk up
or kickback from the workpiece as the saw is
restarted.
Support large panels to minimise the
risk of blade pinching and kickback.
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 improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
Blade depth and bevel adjusting
locking levers must be tight and secure
before making the cut. If blade adjustment
shifts while cutting, it may cause binding and
kickback.
Use extra caution when sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can cause
kickback.
