Read and understand all instructions. Failure to follow all instructions listed
below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the
dust or fumes.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Grounded tools must be plugged into an
outlet properly installed and grounded in
accordance with all codes and
ordinances. Never remove the grounding
prong or modify the plug in any way. Do
not use any adaptor plugs. Check with a
qualified electrician if you are in doubt as
to whether the outlet is properly
grounded. If the tools should electrically
malfunction or break down, grounding
provides a low resistance path to carry
electricity away from the user. Improper
grounding can shock, burn or electrocute.
Grounded tools are equipped with three
conductor cord and three prong type plugs.
Before plugging in the tool be certain the
outlet voltage supplied is within the voltage
marked on the nameplate. Do not use “AC
only” rated tools with a DC power supply.
Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased
risk of electric shock if your body is
grounded. If operating the power tool in
damp locations is unavoidable, a Ground
Fault Circuit Interrupter must be used to
supply the power to your tool. Electrician’s
rubber gloves and footwear will further
enhance your personal safety.
Don't expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the
cord to carry the tools or pull the plug
from an outlet. Keep cord away from
heat, oil, sharp edges or moving parts.
Replace damaged cords immediately.
Damaged cords increase the risk of electric
shock.
When operating a power tool outside, use
an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor
use and reduce the risk of electric shock.
Refer to “Recommended sizes of Extension
Cords” in the Accessory section of this
manual.
Personal Safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry,
or long hair can be caught in moving parts.
Keep handles dry, clean and free from oil
and grease.
Avoid accidental starting. Be sure switch
is “OFF” before plugging in. Carrying tools
with your finger on the switch or plugging in
tools that have the switch “ON” invites
accidents.
Remove adjusting keys or wrenches
before turning the tool “ON”. A wrench or
a key that is left attached to a rotating part of
the tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enables better control of the
tool in unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.

Safety Rules for Circular Saws
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
Do not force tool. Use the correct tool for
your application. The correct tool will do
the job better and safer at the rate for which
it is designed.Do not use tool if switch
does not turn it “ON” or “OFF”. Any tool
that cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely
to bind and are easier to control. Any
alteration or modification is a misuse and
may result in a dangerous condition.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools. Develop
a periodic maintenance schedule for your
tool.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool, may become
hazardous when used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk
of electric shock or injury. Certain cleaning
agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage
plastic parts.
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. Hold
the saw firmly to prevent loss of control. Figures
in this manual illustrate typical hand support of
the saw. NEVER place your hand behind the
saw blade since kickback could cause the saw
to jump backwards over your hand.
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. (See “Causes and Operator
Prevention of Kickback.”)
Do not reach underneath the work. The
guard cannot protect you from the blade below
the work. Do not attempt to remove cut
material when blade is moving.
Check lower guard for proper closing before
each use. Do not operate 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 only with the Lower Guard Lift 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 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 buildup of debris. Disconnect the
plug from power source. Periodically remove
the blade, clean the upper, lower guards and
the hub area with kerosene and wipe it dry, or
blow it clean with compressed air.
Lower guard should be retracted manually
only for special cuts such as “Pocket Cuts”
and “Compound Cuts”. Raise lower guard
by Lower Guard Lift Lever. As soon as blade
enters the material, lower guard must be
released. For all other sawing, the lower guard
should operate automatically.
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.
NEVER hold 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 tool by the insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or it
own cord. Contact with a "live" wire will also
make exposed metal parts of the tool “live” and
shock the operator.
When ripping always use a rip fence or
straight edge guide. This improves accuracy
of cut and reduces the chance for blade
binding.
Always use blades with correct size and
shape (diamond vs. round) arbor holes.
Blades that do not match the mounting
hardware of the saw will run eccentrically,
causing loss of control and will not allow proper
vari-torque engagement.
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.
The blade washers and the bolt on your saw
have been designed to work as a “VARITORQUE CLUTCH”. Understand the operation
and settings of the VARI-TORQUE CLUTCH,
because the proper setting of the CLUTCH,
combined with firm handling of the saw will
allow you to control KICKBACK.
Do not run the saw while carrying it at your
side. Lower guard may be opened by a
contact with your clothing. Accidental contact
with the spinning saw blade could result in
serious personal injury.
Depending upon use, the switch may not
last the life of the saw. If the switch should
fail in the “OFF” position, the saw may not
start. If it should fail while the saw is
running, the saw may not shut off. If either
occurs, unplug the saw immediately and do not
use until repaired.
This circular saw should not be mounted to
a table and converted to a table saw. Circular
saws are not designed or intended to be used
as table saws.
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 tool misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper
precautions as given below:
VARI-TORQUE
CLUTCH
KICKBACK
SM 2610905556 1/03 1/9/03 11:24 AM Page 4
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 action to eliminate the
cause of blade binding. Wet lumber, green
lumber or pressure treated lumber require
special attention during cutting operation to
prevent KICKBACK. Avoid cutting nails. Inspect
for and remove all nails from lumber before
cutting.
When restarting a saw in a 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.
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. See “Cutting Large Sheets” in this
manual.
Do not use dull or damaged blade.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and KICKBACK.
Blade depth and bevel adjusting locking
knobs must be tight and secure before
making cut. If blade adjustment shifts while
cutting, it may cause binding and KICKBACK.
Using the saw with an excessive depth of cut
setting increases loading on the unit and
susceptibility to twisting of the blade in the kerf.
It also increases the surface area of the blade
available for pinching under conditions of kerf
close down.
Use extra caution when making a “Pocket
Cut” into existing walls or other blind areas.
The protruding blade may cut objects that can
cause KICKBACK.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

Assembly
ATTACHING THE BLADE
Disconnect the plug from
the power source before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting
the tool accidentally.
1. Turn blade stud CLOCKWISE with the
wrench provided and remove BLADE STUD
and OUTER WASHER. If the saw shaft moves
while attempting to move the blade stud, strike
the wrench clockwise to jar the wrench loose
(Fig. 2).
2. Retract the lower guard all the way up into
the upper guard. While retracting the lower
guard, check operation and condition of the
LOWER GUARD SPRING.
3. Make sure the saw teeth and arrow on the
blade point in the same direction as the arrow
on the lower guard.
4. Slide blade through slot in the foot and
mount it against the INNER WASHER on the
shaft. Be sure the large diameter of the INNER
and OUTER washers lay flush against the
blade.
5. Reinstall OUTER WASHER and tighten
BLADE STUD finger tight. Place the blade on a
piece of scrap wood and hold the saw
securely by the upper guard (teeth imbedded
in wood) and TIGHTEN BLADE STUD 1/8
TURN (45°) WITH THE WRENCH PROVIDED.
Do not use wrenches with longer handles,
since it may lead to over tightening of the
blade stud.
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.

Disconnect plug from power source. Loosen
the depth adjustment lever located between
the guard and handle of saw. Hold the foot
down with one hand and raise or lower saw
by the handle. Tighten lever at the depth
setting desired. Check desired depth (Fig. 3).
Not more than one tooth length of the blade
should extend below the material to be cut,
for minimum splintering (Fig. 4).

90° CUTTING ANGLE CHECK
Disconnect plug from power source. Set foot
to maximum depth of cut setting. Loosen bevel
adjustment lever, set to 0° on quadrant,
retighten lever and check for 90° angle
between the blade and bottom plane of foot
with a square (Fig. 6). Make adjustments by
turning the small alignment screw, if necessary
(Fig. 5).
BEVEL ADJUSTMENT
Disconnect plug from power source. The foot
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 lever (Fig. 7).
Because of the increased amount of blade
engagement in the work and decreased
stability of the foot, blade binding may occur.
Keep the saw steady and the foot firmly on the
workpiece.
Operating Instructions
ADJUSTABLE LINE GUIDE
For a straight 90° cut you can use the left or
right side of notch in the foot. For 45° bevel
cuts, use the right side (Fig 8). The guide can
be adjusted to allow for variation in blade
thicknesses for whichever side of the blade
the user would prefer to cut the line on.
TO ADJUST: Disconnect plug from power
source. Loosen but don’t remove, the
adjustment screws enough so the guide can
move freely. Set a straightedge flat on the
preferred side of the blade, lining up both the
edge of the straightedge and the edge of the
guide where the 0° mark is located.

SWITCH
This tool is not
recommended for use
with abrasive masonry cut-off wheels.
When starting the tool,
hold it with both hands.
The torque from the motor can cause the tool
to twist.
To turn tool “ON”, squeeze the trigger switch.
To turn the tool “OFF”, release the trigger
switch, which is spring loaded and will return
to the off position automatically.
Your saw should be running at full speed
BEFORE starting the cut, and turned off only
AFTER completing the cut. To increase
switch life, do not turn switch on and off while
cutting.
GENERAL CUTS
Always hold the saw handle with one hand
and the auxiliary handle or housing with the
other.
Always be sure either hand
does not interfere with the
free movement of the lower guard.
Maintain a firm grip and operate the switch
with a decisive action. Never force the saw.
Use light and continuous pressure.
After completing a cut and
the trigger has been
released, be aware of the necessary time it
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.
CROSS CUTS
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.
POCKET CUTS
Disconnect the plug from the power source
before making adjustments. Set depth adjustment according to material to be cut. Tilt saw
forward with cutting guide notch lined up with
the line you’ve drawn. Raise the lower guard,
using lift lever and hold the saw by the front
and rear handles (Fig. 9).
With the blade just clearing the material to be
cut, start the motor. Gradually lower the back
end of saw using the front end of the foot as
the hinge point.
As blade starts cutting the
material, release the lower
guard immediately. When the foot rests flat on
the surface being cut, proceed cutting in
forward direction to end of cut.
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.
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.

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. 10).
Support the panel or board close to the cut, as
shown in (Fig. 11). 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 two-by-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.

Service
Preventive maintenance
performed by unauthorized
personnel may result in misplacing of
internal wires and components which
could cause serious hazard. We
recommend that all tool service be performed
by a Skil Factory Service Center or
Authorized Skil Service Station.
TOOL LUBRICATION
Your Skil tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CARBON BRUSHES
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.
Only genuine Skil replacement brushes
specially designed for your tool should be
used.
BEARINGS
After about 300-400 hours of operation, or at
every second brush change, the bearings
should be replaced at Skil Factory Service
Center or Authorized Skil Service Station.
RIP CUTS
The combination blade provided with your saw
is for both cross cuts and rip cuts. Ripping is
cutting lengthwise with the grain of the wood.
Rip cuts are easy to do with a rip fence
(Fig. 12). Rip Fence is available as an accessory
(not included). To attach fence, insert fence
through slots in foot to desired width as shown
and secure with the wing nut (not included).
