ADDITIONAL SAFETY RULES FOR CIRCULAR SAWS

DANGER! Keep hands away from cutting area and 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.
•
Keep your body positioned to either side of the saw blade, but not in line
with the saw blade. Kickback could cause the saw to jump backwards.
•
Do not reach underneath the workpiece. The guard cannot protect you from
the blade below the work.
•
Check 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 in the open position. If the saw is accidentally
dropped, the lower guard may be bent. Raise the lower guard with the guard
retraction lever and make sure it moves freely and does not touch the blade
or any other part, in all angles and depths of cut.
•
Check the operation and condition of the lower guard spring. If the guard
and the spring are not operating properly, they must be serviced before use.
The lower guard may operate sluggishly due to damaged parts, gummy
deposits, or a buildup of debris.
•
The lower guard should be retracted manually only for special cuts such
as "Pocket Cuts" and "Compound Cuts". Raise the lower guard using the
guard retraction lever. As soon as the blade enters the material, the lower
guard must be released. For all other sawing tasks, the lower guard should
operate automatically.
•
Always check that the lower guard is covering the blade before placing the
saw down on a bench or the 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 the switch is released.
•
NEVER hold the piece being cut in your hands or across your leg. It is
important to support the work properly to minimize body exposure, blade
binding, or loss of control.
•
Hold the tool by the 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 tool
"live" and could cause an electric shock to the operator.
•
When ripping, always use a rip fence or straight edge guide. This improves
the accuracy of cut and reduces the chance of the blade binding.
•
Always use blades of the correct size and shape (diamond vs. round) 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.
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 operator.

ADDITIONAL SAFETY RULES FOR CIRCULAR SAWS
Kickback is the result of tool 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 body and
arm to allow you to resist kickback forces. 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, center the saw blade in the kerf
and check that the saw teeth are not engaged into the material. If the saw
blade is binding, it may jump up or kick back from the workpiece as the saw
is restarted.
•
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.
•
Do not use dull or damaged blades. Unsharpened or improperly set blades
produce a narrow kerf causing excessive friction, blade binding and kickback.
•
Blade depth and bevel adjusting locking levers must be tight and secure
before making a cut. If the blade adjustment shifts while cutting, it may
cause binding and kickback.
•
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.
•
Do not use blades made of high-alloy, high-speed steel (HSS).
•
Do not use the circular saw near fumes or combustible liquids.
•
Secure small pieces of wood firmly before working. Never hold them in
your hand.
•
Never slow the blade down with your hands or by applying pressure to the
side of the blade.
•
Never apply force! Advance the circular saw gently and steadily.
EXTENSION CORDS
•
Replace damaged cords immediately. Use of damaged cords can shock,
burn or electrocute.
•
If an extension cord is necessary, a cord with adequate size conductors
should be used to prevent excessive voltage drop, loss of power or
overheating. The table shows the correct size to use, depending on cord
length and nameplate amperage rating of tool. If in doubt, use the next
heavier gauge. Always use U.L. and CSA listed extension cords.
