WARNING:
Never use abrasive cut-off wheels of any kind with
this saw. Use of non wood cutting blades can result in
property damage or serious personal injury.
KICKBACK
See Figures 4 - 7, page 17.
Kickback occurs when the blade stalls rapidly and the saw
is driven back towards you. Blade stalling is caused by any
action which pinches the blade in the wood.
DANGER:
Release switch immediately if blade binds or saw stalls.
Kickback could cause you to lose control of the saw. Loss
of control can lead to serious injury.
To guard against kickback, avoid dangerous practices such
as the following:
 Setting blade depth incorrectly
 Sawing into knots or nails in workpiece
 Twisting the blade while making a cut
 Making a cut with a dull, gummed up, or improperly set
blade
 Supporting the workpiece incorrectly
 Forcing a cut
 Cutting warped or wet lumber
 Operating the tool incorrectly or misusing the tool
To lessen the chance of kickback, follow these safety
practices:
 Keep the blade at the correct depth setting. Less than a
full tooth of the blade teeth should be visible below the
workpiece.
 Inspect the workpiece for knots or nails before cutting.
Never saw into a knot or nail.
 Make straight cuts. Always use a straight edge guide
when rip cutting. This helps prevent twisting the blade.
 Use clean, sharp, and properly set blades. Never make
cuts with dull blades.
 Support and clamp the workpiece properly before
beginning a cut.
 Use steady, even pressure when making a cut. Never
force a cut.
 Do not cut warped or wet lumber.
 Hold the saw firmly with both hands and keep your body
in a balanced position so as to resist the forces if kickback
should occur.
OPERATION
WARNING:
When using the saw, always stay alert and exercise
control. Do not remove the saw from the workpiece while
the blade is moving.
SAW BLADES
The best of saw blades will not cut efficiently if they are not
kept clean, sharp, and properly set. Using a dull blade will
place a heavy load on the saw and increase the danger of
kickback. Keep extra blades on hand, so that sharp blades
are always available.
Gum and wood pitch hardened on blades will slow the
saw down. Remove saw blade from the saw and use gum
and pitch remover, hot water, or kerosene to remove these
accumulations. DO NOT USE GASOLINE.
BLADE GUARD SYSTEM
See Figure 8, page 17.
The lower blade guard attached to the circular saw is there
for your protection and safety. Do not alter it for any reason.
If it becomes damaged, do not operate the saw until you
have the guard repaired or replaced. Always leave guard in
operating position when using the saw.
DANGER:
When sawing through work, lower blade guard does not
cover blade on the underside of work. Since blade is
exposed on underside of work, keep hands and fingers
away from cutting area. Any part of your body coming
in contact with moving blade will result in serious injury.
WARNING:
Never tie the lower blade guard in a raised position.
Leaving the blade exposed could lead to serious injury.
CAUTION:
Never use saw when guard is not operating correctly.
Check the guard for correct operation before each use.
The guard is operating correctly when it moves freely and
readily returns to the closed position. If you drop the saw,
check the lower blade guard and bumper for damage at
all depth settings before reuse.
