General Power Tool Safety Warnings
!
WARNING
Read all safety warnings and instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in all of the warnings refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered
or 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 children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric
shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
Do not 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
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
If operating the power tool in damp locations
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduce the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention
while operating power tools may result in
serious personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
switch is in the off-position before
connecting to power source and / or battery
pack, picking up or carrying the tool.
Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a
key left attached to a rotating part of the power
tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
Power tool use and care
Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at
the rate for which it was designed.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that
cannot be controlled with the switch is
dangerous and must be repaired.

SM 1619X03832 09-09:SM 1619X03832 09-09 9/10/09 1:22 PM Page 3
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s operation. If damaged,
have the power tool repaired before use.
Many accidents are caused by poorly
maintained power tools.
Safety Rules for Circular Saws
WARNING
!
Cutting procedures
!
DANGER
Keep your second hand on auxiliary handle,
or motor housing. If both hands are holding
the saw, they cannot be cut by the blade.
Do not reach underneath the workpiece.
The guard cannot protect you from the blade
below the workpiece.
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.
Never hold piece being cut in your hands
or across your leg.Secure the workpiece to
stable platform. It is important to support the
work properly to minimize body exposure,
blade binding, or loss of control.
Hold power tool by 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 the
accuracy of cut and reduces the chance for
blade binding.
Keep hands away from
cutting area and the blade.
Read all safety warnings and all instructions.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified
repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
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.
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.
Inspect the condition and quality of the
wood and remove all nails from lumber
before cutting. Wet lumber, green lumber or
pressure treated lumber require special
attention during cutting operation to prevent
kickback.
Hold the saw firmly to prevent loss of
control. Figures in this manual illustrate
typical hand support of the saw.
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.

Kickback and related warnings
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:
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.
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.
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.
Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive friction,
blade binding and kickback.
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.
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.
The blade washers and the bolt on your
saw have been designed to work as a
clutch to reduce the intensity of a kickback.
Understand the operation and settings of
the VARI-TORQUE CLUTCH. The proper
setting of the clutch, combined with firm
handling of the saw will allow you to control
kickback.
VARI-TORQUE
CLUTCH
Never place your hand behind the saw
blade. Kickback could cause the saw to jump
backwards over your hand.
Do not use the saw with an excessive
depth of cut setting. Too much blade
exposure increases the likelihood of the blade
twisting in the kerf and increases the surface
area of the blade available for pinching that
leads to kickback.
Lower guard function
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
-4-
SM 1619X03832 09-09:SM 1619X03832 09-09 9/10/09 1:22 PM Page 5
before use. Lower guard may operate
sluggishly due to damaged parts, gummy
deposits, or a buildup of debris.
Lower guard should be retracted manually
only for special cuts such as “Plunge Cuts”
and “Compound Cuts”. Raise lower guard
by lower guard lift lever and 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
Additional Safety Warnings
GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
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.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
the tool since internal wires may be
misplaced or pinched or safety guard return
springs may be improperly mounted.
Certain cleaning agents such as gasoline,
backwards, cutting whatever is in its path. Be
aware of the time it takes for the blade to stop
after switch is released.
Do not run the tool 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.
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. Preventive maintenance
and properly operating guard will reduce the
probability of an accident.
carbon tetrachloride, ammonia, etc. may
damage plastic parts.
Risk of injury to user. The power cord must only
be serviced by a Skil Factory Service Center or
Autho rized Skil Service Station.

WARNING
!
Disconnect the plug from

safety measures reduce the risk of starting
the tool accidentally.
1. Press the lock button and turn wrench until
lock button en gages. Saw shaft is now locked.
Continue to depress button, turn wrench
counter-clockwise and remove BLADE STUD
and OUTER WASHER (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 OUTER
washer lays flush against the blade.

5. Reinstall OUTER WASHER. First tighten
BLADE STUD finger tight, then 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 ex cessive
resistance, thus reducing saw’s tendency to
KICKBACK.
One setting may not be sufficient for cutting all
materials. If ex cessive 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.

WARNING
!
have the saw plugged into a power source.
Pay attention to the placement of the saw
blade with respect to your hands and body
and avoid accidental actuation of the
power switch. Accidental start-up of the saw
may cause injury.
Your tool is equipped with a laser line guide
that will turn on whenever the tool is plugged
in and the laser button is pushed in (Fig. 1).
The two laser lines are set to the kerf of the
blade supplied and indicate the outer edges of
the blade. If you use a blade with a different
kerf the laser lines will need to be adjusted to
match the kerf of the new blade. You should
adjust the laser lines to whichever side of the
blade the user would prefer the cut line to be
on. The laser guide does not need to be
adjusted for bevel cuts after it is aligned for
straight 90° cuts.
If using the laser line guide for cutting you do
not need the line guide incorporated in the foot
as it may be in a different setting than the
laser line guide.
The laser light guide is a class IIIA laser with a
maximum output power of 5.0 mWatts and
conforms to 21 CFR 1040.10 and 1040.11.
TO ADJUST: Use a flat head screwdriver to
turn the adjustment screw located on the side
of the laser module (Fig. 9). Turn on the laser
line guide by pressing the safety switch and
rotate the adjustment screw until the laser line
is aligned. There is no need to power the saw
“on” while adjusting the light beam.
The Laser line guide has a limited amount of
travel. Do not continue to turn the adjustment
screw after the line stops moving or if it
