Safety warnings for all saws
Sawing methods
•
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.
•
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
workpiece.
Less than a full tooth of the blade teeth should
be visible below the workpiece.
•
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 properly to minimise
body exposure, blade binding, or loss of control.
•
Hold the power tool by its insulated gripping surfaces
when performing an operation where the cutting
accessory 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
guide.
This improves the accuracy of cut and reduces the
chance of blade binding.
•
Always use saw 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.
•
Never use damaged or incorrect blade washers or
bolts.
The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
Further safety warnings for all saws
Kickback causes and related warnings
A 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
workpiece 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 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.
•
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 backwards 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 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.
•
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.
•
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 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.
Safety warnings for circular saws with pendulum guard
and circular saws with tow guard – Lower guard function
•
Check the lower guard for proper closure before each
use. Do not operate the saw if the lower guard does
not move freely and close immediately. Never clamp or
tie the lower guard in the open position.
The lower guard may be bent if the saw accidentally falls
to the floor. Use the retracting lever to raise the guard and
make sure that it moves freely and does not touch the
blade or any other part of the saw at all cutting angles and
depths of cut.
•
Check that the lower guard spring operates correctly.
If the guard and spring do not operate correctly, have
the saw serviced before use.
Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
