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.
LOWER GUARD
SPRING
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.

ADJUSTABLE LASER LINE GUIDE
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
