GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS

Failure to follow all instructions listed below may result in

electric shock, fire, and/or serious injury.

SAVE THESE INSTRUCTIONS

WORK AREA

1. Keep your work area clean and well lit. Cluttered benches and dark areas

invite accidents.

2. 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.

3. Keep bystanders, children, and visitors away while operating a power tool.

Distractions can cause you to lose control. Protect others in the work area from

debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY

4. 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 adapter

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.

5. Double insulated tools are equipped with a polarized plug (one blade is

wider than the other). This plug will fit in a polarized outlet only one way. If

the plug does not fit fully in the outlet, reverse the plug. If it still does not

fit, contact a qualified electrician to install a polarized outlet. Do not

change the plug in any way. Double insulation eliminates the need for the

three wire grounded power cord and grounded power supply system.

6. 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.

7. Do not expose power tools to rain or wet conditions. Water entering a power

tool will increase the risk of electric shock.

8. Do not abuse the Power Cord. Never use the Power Cord to carry the tools

or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,

sharp edges, or moving parts. Replace damaged Power Cords immedi-

ately. Damaged Power Cords increase the risk of electric shock.

9. When operating a power tool outside, use an outdoor extension cord

marked “W-A” or “W”. These extension cords are rated for outdoor use, and

reduce the risk of electric shock.

PERSONAL SAFETY

10. Stay alert. Watch what you are doing, and use common sense when oper-

ating a power tool. Do not use a power tool while tired or under the influ-

ence of drugs, alcohol, or medication. A moment of inattention while operat-

ing power tools may result in serious personal injury.

11. 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.

12. Avoid accidental starting. Be sure the Power Switch is off before plugging

in. Carrying power tools with your finger on the Power Switch, or plugging in

power tools with the Power Switch on, invites accidents.

13. Remove adjusting keys or wrenches before turning the power tool on. A

wrench or a key that is left attached to a rotating part of the power tool may result

in personal injury.

14. Do not overreach. Keep proper footing and balance at all times. Proper

footing and balance enables better control of the power tool in unexpected

situations.

15. Use safety equipment. Always wear eye protection. Dust mask, non-skid

safety shoes, hard hat, or hearing protection must be used for appropriate

conditions.

TOOL USE AND CARE

16. Use clamps (not included) or other practical ways 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.

17. Do not force the 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.

18. Do not use the power tool if the Power Switch does not turn it on or off.

Any tool that cannot be controlled with the Power Switch is dangerous and must

be replaced.

19. Disconnect the Power Cord 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.

20. Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

21. Maintain tools with care. Keep cutting tools sharp and clean. Properly

maintained tools with a sharp cutting edge are less likely to bind and are easier

to control. Do not use a damaged tool. Tag damaged tools “Do not use” until

repaired.

22. Check for misalignment or binding of moving parts, breakage of parts, and

any other condition that may affect the tool’s operation. If damaged, have

the tool serviced before using. Many accidents are caused by poorly main-

tained tools.

23. 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

24. Tool service must be performed only by qualified repair personnel. Service

or maintenance performed by unqualified personnel could result in a risk of injury.

25. When servicing a tool, use only identical replacement parts. Follow

instructions in the “Inspection, Maintenance, And Cleaning” section of this

manual. Use of unauthorized parts or failure to follow maintenance instructions

may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES

1. Maintain labels and nameplates on the Circular Saw. These carry impor-

tant information. If unreadable or missing, contact Harbor Freight Tools for a

replacement.

2. Always wear safety impact eye goggles when using the Circular Saw.

Using personal safety devices reduce the risk for injury. Safety impact eye

goggles are available from Harbor Freight Tools.

3. Maintain a safe working environment. Keep the work area well lit. Make sure

there is adequate surrounding workspace. Always keep the work area free of

obstructions, grease, oil, trash, and other debris. Do not use a power tool in

areas near flammable chemicals, dusts, and vapors. Do not use this product in a

damp or wet location.

4. Make sure to read and understand all instructions and safety precautions

as outlined in the manufacturer’s manual.

5. When using a hand-held power tool, always maintain a firm grip on the tool

with both hands to resist starting torque.

SKU 04042 PAGE 5

6. Always keep the power supply cord away from moving parts on the tool.

Keep the cord away from the direction of the cut.

7. Avoid unintensional starting. Make sure you are prepared to begin work

before turning on the Circular Saw.

8. Do not force the Circular Saw. This tool will do the work better and safer at

the speed and capacity for which it was designed.

9. Never lay the Circular Saw down until the blade has come to a complete

stop.

10. Never leave the Circular Saw unattended when it is plugged into an

electrical outlet. Turn off the tool, and unplug it from its electrical outlet before

leaving.

Brought to You by Augusta Flint

11. Always unplug the Circular Saw from its electrical outlet before

performing and inspection, maintenance, or cleaning procedures.

12. WARNING! Some dust created by power sanding, sawing, grinding, drilling,

and other construction activities, contain chemicals known (to the State of Cali-

fornia) to cause cancer, birth defects or other reproductive harm. Some ex-

amples of these chemicals are: lead from lead-based paints, crystalline silica

from bricks and cement or other masonry products, 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.

(California Health & Safety Code 25249.5, et seq.)

13. WARNING! People with pacemakers should consult their physician(s)

before using this product. Operation of electrical equipment in close proximity to

a heart pacemaker could cause interference or failure of the pacemaker.

SKU 04042 PAGE 6

14. REDUCE THE RISK OF ACCIDENTAL STARTING. Make sure the Power

Switch (part #45) is in the “OFF” position before plugging the Power Cord

(part #53) into a grounded, 115 Volt, electrical outlet.

15. ALWAYS USE THE PROPER SIZE AND TYPE OF SAW BLADE (part #68):

7-1/4” DIAMETER - 6,000 MAXIMUM RATED RPM OR GREATER.

16. KEEP HANDS AND FINGERS CLEAR OF THE TURNING SAW BLADE

(part #68) AT ALL TIMES.

17. FEED THE CIRCULAR SAW GRADUALLY ONTO THE WORKPIECE. Do not

force the Circular Saw to remove material faster than it was designed to cut.

18. WHEN CUTTING A LARGE WORKPIECE, MAKE SURE IT IS PROPERLY

SUPPORTED.

19. SECURE THE WORKPIECE. Whenever possible, secure the workpiece with a

vise or clamps (not included).

20. AVOID KICKBACK. When the Saw Blade (part #68) is pinched or tightly

bound when cutting the Saw Blade will stall, driving the Circular Saw

rapidly back toward the operator. Always make a cut straight and gradual to

avoid the Saw Blade being twisted or misaligned in the cut.

21. DANGER! 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.

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 can not protect you from the

blade below the work.

SKU 04042 PAGE 7

22. 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 with the Retracting Handle and make

sure it moves freely and does not touch the blade or any other part, in all angles

and depths of cut.

23. Check the operation and condition 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.

24. Lower guard should be retracted manually only for special cuts such as

“Pocket Cuts” and “Compound Cuts”. Raise lower guard by Retracting

Handle. As soon as blade enters the material, lower guard must be released.

For all other sawing, the lower guard should operate automatically.

25. 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 release.

26. 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.

27. Hold tool by insulated gripping surfaces when performing an operation

where the cutting tool may contact wiring or its own cord. Contact with a

“live” wire will also make exposed metal parts of the tool “live” and shock the

operator.

28. When ripping always use a rip fence or straight edge guide. This improves

the accuracy of cut and reduces the chance for blade binding.

29. 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.

30. Never use damaged or incorrect blade washers or bolts. The blade washers

and bolts were specially designed for your saw, for optimum performance and

safety of operation.

SKU 04042 PAGE 8

31. 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 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:

32. 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.

33. 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.

Investi gate and take corrective actions to eliminate the cause of blade binding.

34. When restarting a saw in the 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.

35. 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.

36. Do not use dull or damaged blade. Unsharpened or improperly set blades

produce narrow kerf causing excessive friction, blade binding and KICKBACK.

37. 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.

38. 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.

GROUNDING

WARNING!

GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS

1. Tools marked with “Grounding Required” have a three wire cord and three prong

grounding plug. The plug must be connected to a properly grounded outlet. If

the tool should electrically malfunction or break down, grounding provides a low

resistance path to carry electricity away from the user, reducing the risk of elec-

tric shock. (See Figure A.)

2. The grounding prong in the plug is connected through the green wire inside the

cord to the grounding system in the tool. The green wire in the cord must be the

only wire connected to the tool’s grounding system and must never be attached

to an electrically “live” terminal. (See Figure A.)

3. Your tool must be plugged into an appropriate outlet, properly installed and

grounded in accordance with all codes and ordinances. The plug and outlet

should look like those in the following illustration. (See Figure A.)

Improperly connecting the grounding wire can result in the risk of electric

shock. Check with a qualfified electrician if you are in doubt as to whether the

outlet is properly grounded. Do not modify the power cord plug provided with

the tool. Never remove the grounding prong from the plug. Do not use the

tool if the power cord or plug is damaged. If damaged, have it repaired by

a service facility before use. If the plug will not fit the outlet, have a proper

outlet installed by a qualified electrician.

SKU 04042 PAGE 10

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS

4. Tools marked “Double Insulated” do not require grounding. They have a special

double insulation system which satisfies OSHA requirements and complies with

the applicable standards of Underwriters Laboratories, Inc., the Canadian

Standard Association, and the National Electrical Code. (See Figure B.)

5. Double insulated tools may be used in either of the 120 volt outlets shown in the

following illustration. (See Figure B.)

EXTENSION CORDS

1. Grounded tools require a three wire extension cord. Double Insulated tools

can use either a two or three wire extension cord.

2. As the distance from the supply outlet increases, you must use a heavier gauge

extension cord. Using extension cords with inadequately sized wire causes a

serious drop in voltage, resulting in loss of power and possible tool damage.

(See Figure C, next page.)

3. The smaller the gauge number of the wire, the greater the capacity of the cord.

For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.

(See Figure C.)

4. When using more than one extension cord to make up the total length, make

sure each cord contains at least the minimum wire size required.

(See Figure C.)

5. If you are using one extension cord for more than one tool, add the nameplate

amperes and use the sum to determine the required minimum cord size.

(See Figure C.)
