Safety Instructions for All 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 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
minimize body exposure, blade binding, or loss ofcontrol.
e ) Hold the power tool by insulated gripping surfaces,
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 arbor holes. Blades that do not
match the mounting hardware of the saw will run off-center,
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.
Further Safety Instructions for all Saws
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;
- 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
power tool’s operation. If damaged, have the power tool
repaired before use. Many accidents are caused by poorly
maintained powertools.
f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier tocontrol.
g ) Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into account
the working conditions and the work to be performed.
Use of the power tool for operations different from those
intended could result in a hazardoussituation.
h ) Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the tool
in unexpected situations.
5) Service
a ) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
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:
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, center
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.
d ) Support large panels to minimize 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. Unsharpened or
improperly set blades produce narrow kerf causing 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 the lower guard for proper closing before each
use. Do not operate the saw if the lower guard does not
move freely and close instantly. Never 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 damaged parts, gummy deposits, or a build-
up of debris.
c ) The lower guard may be retracted manually only for
special cuts such as “plunge cuts” and “compound cuts.”
Raise the lower guard by retracting the handle and as
soon as the blade enters the material, the lower guard
must be released. For all other sawing, the lower guard
should operate automatically.
d ) Always observe that the lower guard is covering
the blade before placing saw down on bench or floor.
An unprotected, coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is released.
