Circular Saw Safety Warnings
1.
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.
2.
Do not reach underneath the workpiece.
The guard cannot protect you from
the blade below the workpiece.
3.
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.
4.
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 minimize body exposure,
blade binding, or loss of control.
5.
Hold 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 shock the operator.
6.
When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut
and reduces the chance of blade binding.
7.
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 eccentrically, causing loss of control.
8.
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.
9.
Causes and Operator Prevention of Kickback:
• 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 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 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 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 making a
″plunge cut″ into existing walls or other
blind areas. The protruding blade may
cut objects that can cause kickback.
10.
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 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.
11.
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.
