Circular
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.
VARI-TORQUE
CLUTCH
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 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

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.

Do not use wrenches with longer handles,

VARI-TORQUE CLUTCH
This clutching action is provided by the friction
of the OUTER WASHER against the BLADE
and permits the blade shaft to turn when the
blade encounters excessive resistance. When
the BLADE STUD is properly tightened (as
described in No. 5 of Attaching The Blade), the
blade will slip when it encounters excessive
resistance, thus reducing saw’s tendency to
KICKBACK.
One setting may not be sufficient for cutting all
materials. If excessive blade slippage occurs,
tighten the blade stud a fraction of a turn more
(less than 1/8 turn). OVERTIGHTENING THE
BLADE STUD NULLIFIES THE EFFECTIVENESS OF THE CLUTCH.

can be adjusted up to 45° by loosening the
bevel adjustment lever at the front of the saw.
Align to desired angle on calibrated quadrant.
Then tighten bevel adjustment first, then the
depth adjustment lever (Fig. 5). Because of the
increased amount of blade engagement in the

takes for the blade to come to a complete
stop during coast down. Do not allow the
saw to brush against your leg or side,
since the lower guard is retractable, it
could catch on your clothing and expose
the blade. Be aware of the necessary blade
exposures that exist in both the upper and
lower guard areas.
When cutting is interrupted, to resume cutting:
squeeze the trigger and allow the blade to
reach full speed, re-enter the cut slowly and
resume cutting.
When cutting across the grain, the fibers of
the wood have a tendency to tear and lift.
Advancing the saw slowly minimizes this
effect. For a finished cut, a cross cut blade or
miter blade is recommended.
CUTTING MASONRY/METAL
This tool is not recommended for continuous
and general usage with metal or masonry cutoff wheels. If you use your saw for cutting
these materials, use the appropriate wheel for
the material being cut.
When cutting masonry, do not cut a depth of
more than 1/4 inch (6 mm). Make successive
passes to achieve desired depth. Apply a light
forward pressure. Do not overload motor.
When starting the tool,
hold it with both hands.

WARNING
!
Allow blade to come to a
complete stop before lifting
the saw from cut. Also, never pull the saw
backward since blade will climb out of the
material and KICKBACK will occur.
CUTTING LARGE SHEETS
Large sheets and long boards sag or bend,
depending on support. If you attempt to cut
without leveling and properly supporting the
piece, the blade will tend to bind, causing KICKBACK and extra load on the motor (Fig. 8).
Support the panel or board close to the cut, as
shown in (Fig. 9). Be sure to set the depth of the
cut so that you cut through the sheet or board
only and not the table or work bench. The twoby-fours used to raise and support the work
should be positioned so that the broadest sides
support the work and rest on the table or bench.
Do not support the work with the narrow sides
as this is an unsteady arrangement. If the sheet
or board to be cut is too large for a table or work
bench, use the supporting two-by-fours on the
floor and secure.
Turn saw around and finish the cut in the normal
manner, sawing forward. If corners of your
pocket cut are not completely cut through, use a
jigsaw or hand saw to finish the corners.

Your Skil tool has been properly lubricated and
is ready to use. However it is recommended
that the gears be relubricated only with Skil
lubricants: No. 80111 (8 oz. tube), No. 80112
(pint) or No. 80113 (1/2 gal. can).
Always check the
oil level before
using the saw. To
check and add oil:
Remove plug from
power source and
place the saw’s foot on a horizontal surface.
Remove oil plug using the same wrench used
to remove the saw blade. The oil level should
never be below bottom threads in the housing.
When adding oil, fill until oil starts to run out of
oil hole at arrow on housing and replace oil
plug.
NOTE: If oil is extra dirty or thick, replace the
plug and run the saw for one minute to warm
up the oil. Then remove oil plug and turn saw
upside down, to remove all oil. Fill housing
with kerosene. Replace plug and run for one
minute to flush out the gear housing. Drain out
the kerosene and add fresh Skil lubricant. With
a new saw, change the oil after the first ten
hours of use.
The brushes and commutator in your tool have
been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brushes be examined.
The brushes should be free from dust and dirt.
Brushes should be replaced when they have
worn down to 3/16" in length. The brushes
should slide freely in and out of the holders
without sticking.
To check brushes: Disconnect plug from
