IMPORTANT SAFETY INFORMATION

General Power Tool Safety Warnings

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 the warnings refers to your mains-operated (corded) power tool.

Work area safety

1. Keep work area clean and well lit.

Cluttered or 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 children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

Electrical safety

1. Power tool plugs must match the outlet. Never modify the plug in any way.

Do not use any adapter plugs with grounded

power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

2. 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.

3. Do not expose power tools to rain or wet

conditions. Water entering a power tool will increase the risk of electric shock.

4. 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.

Electrical safety (cont.)

5. 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.

Personal safety

1. 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.

2. Use safety equipment. Always wear eye

protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

3. 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.

4. 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.

Power tool use and care

1. 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.

2. 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.

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.

4. 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.

6. If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit

Interrupter (GFCI) protected supply.

Use of a GFCI reduces the risk of electric shock.

5. Do not overreach. Keep proper footing and

balance at all times. This enables better control of the power tool in unexpected situations.

6. 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.

7. If devices are provided for the connection of dust extraction and collection facilities, ensure

these are connected and properly used. Use of these devices can reduce dust-related hazards.

8. Only use safety equipment that has been

approved by an appropriate standards agency.

Unapproved safety equipment may not provide adequate protection. Eye protection must be ANSI-approved and breathing protection must be NIOSH-approved for the specific hazards in the work area.

5. 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.

6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

7. Use the power tool, accessories and blades 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.

Circular Saw Safety Warnings

1. DANGER: Keep hands away from cutting area and the blades. Keep your second hand on

auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blades.

2. Do not reach underneath the workpiece.

The guard cannot protect you from the blades below the workpiece.

3. Adjust the cutting depth to the thickness of the

workpiece. Less than a full tooth of the blades’ teeth should be visible below the workpiece.

4. Never hold piece being cut in your hands or across your leg. Secure the workpiece

to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.

5. Hold power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden

wiring or its own cord. Contact with a ″live″ wire will also make exposed metal parts of the power tool ″live″ and shock the operator.

6. When ripping always use a rip fence or straight

edge guide. This improves the accuracy of cut and reduces the chance of blade binding.

7. 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.

8. 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.

9. Causes and Operator Prevention of Kickback:

• Kickback is a sudden reaction to a pinched, bound or misaligned saw blades, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;

• When the blades are pinched or bound tightly by the kerf closing down, the blades stall and the motor reaction drives the unit rapidly back toward the operator;

• If the blades become twisted or misaligned in the cut, the teeth at the back edge of the blades can dig into the top surface of the wood causing the blades to climb out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: a. 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 blades, but not in line with the blades.

Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.

b. When blades are binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blades come to a complete stop.

Never attempt to remove the saw from the work or pull the saw backward while the

blades are in motion or kickback may occur.

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

c. When restarting a saw in the workpiece, center the saw blades in the kerf and check that saw teeth are not engaged

into the material. If saw blades are binding, they may walk up or kickback from the workpiece as the saw is restarted.

d. 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.

e. Do not use dull or damaged blades.

Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.

f. 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.

g. Use extra caution when making a

″plunge cut″ into existing walls or other

blind areas. The protruding blades may cut objects that can cause kickback.

Circular Saw Safety Warnings (cont.)

10. Check lower guard for proper closing before each use. Do not operate the 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 blades or any other part, in all angles and depths of cut.

11. 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 build-up of debris.

12. Lower guard should be retracted manually only for special cuts such as ″plunge cuts″ and ″compound cuts.″ Raise lower guard by retracting handle and as soon as blades enter the material, the lower guard must

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

13. Always observe that the lower guard is covering the blades before placing saw down on bench

or floor. Unprotected, coasting blades will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blades to stop after switch is released.

14. DO NOT USE THIS SAW WITH THE

SAW HELD UPSIDE DOWN IN A VISE.

The saw is not designed for such use and cannot be used safely in that position.

15. Do not use to cut logs, tree limbs, or uneven lumber.

16. Wet lumber, green (unseasoned) lumber, and pressure treated lumber all have an increased potential for kickback and should only be cut with blades for cutting that lumber type. Wear a NIOSH-approved respirator and have appropriate ventilation whenever cutting pressure treated lumber.

17. Do not use blades made from high-speed steel, abrasive blades, metal-cutting blades or masonry-

cutting blades. The guards of this saw are not designed to protect against the failure of such blades.

18. Place the larger portion of the saw base on

the larger, supported part of the workpiece.

This will help maintain balance and control while the cut is completed.

19. Closely observe position of saw’s housing during cut.

Do not let housing bump up against material being cut.

20. Blades must be rated to at least the maximum speed marked on the tool. Use only blades designed SPECIFICALLY for this saw.

21. Maintain labels and nameplates on the tool.

These carry important safety information.

If unreadable or missing, contact Harbor

Freight Tools for a replacement.

22. Avoid unintentional starting.

Prepare to begin work before turning on the tool.

23. Do not lay the tool down until it has come to a complete stop. Moving parts can grab the surface and pull the tool out of your control.

24. When using a handheld power tool, maintain a firm grip on the tool with both hands to resist starting torque.

25. Do not leave the tool unattended when it is plugged into an electrical outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.

26. 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.

27. This product is not a toy.

Keep it out of reach of children.

28. Verify that there are no utility lines or hardware in or near the workpiece.

This is especially critical for plunge cuts.

29. Do not depress the spindle lock when starting or during operation.

Circular Saw Safety Warnings (cont.)

30. WARNING: Handling the cord on this product will expose you to lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. Wash hands after handling.

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

31. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of California] 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 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.)

Vibration Safety

This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:

1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical checkups to ensure medical problems are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, nervous system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any medical or physical symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.

32. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure. In addition, people with pacemakers should:

• Avoid operating alone.

• Do not use with power switch locked on.

• Properly maintain and inspect to avoid electrical shock.

• Any power cord must be properly grounded.

Ground Fault Circuit Interrupter (GFCI) should also be implemented – it prevents sustained electrical shock.

33. The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

2. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury.

3. Use tools with the lowest vibration when there is a choice.

4. Include vibration-free periods each day of work.

5. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.

6. To reduce vibration, maintain the tool as explained in this manual. If any abnormal vibration occurs, stop use immediately.

Grounding

TO PREVENT ELECTRIC SHOCK AND DEATH

FROM INCORRECT GROUNDING WIRE CONNECTION:

Check with a qualified 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. 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.

Double Insulated Tools: Tools with Two Prong Plugs

1. 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.

2. Double insulated tools may be used in either of the

120 volt outlets shown in the preceding illustration.

(See Outlets for 2-Prong Plug.)

Extension Cords

1. 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 Table A.)

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 Table A.)

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 Table A.)

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 Table A.)

Outlets for 2-Prong Plug

6. If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in

Canada) to indicate it is acceptable for outdoor use.

7. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.

8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.

Using Lubrication Unit

1. The blades for the Double Cut Saw are

“dry cut” teeth. This mean the blades only need to be lubricated in extreme cutting situations, such as when cutting aluminum, copper, stainless steel and cast iron.

2. To use Lubrication Unit, use cutter paste that is in rod form which can be inserted into the center of the Lubrication Unit.

3. Once paste rod is inserted, turn the

Lubrication Unit’s feeder wheel.

Work Piece and Work Area Set Up

1. Wooden work piece selection: a. Work piece must be free of foreign objects and loose knots.

b. Do not use to cut logs, tree limbs, or uneven lumber.

c. Wet lumber, green (unseasoned) lumber, and pressure treated lumber all have an increased potential for kickback and should only be cut with a blade designed for cutting that lumber. Wear a NIOSH-approved respirator and have appropriate ventilation whenever cutting pressure treated lumber.

2. Designate a work area that is clean and well-lit.

The work area must not allow access by children or pets to prevent distraction and injury.

3. Route the power cord along a safe route to reach the work area without creating a tripping hazard or exposing the power cord to possible damage. The power cord must reach the work area with enough extra length to allow free movement while working.

4. Secure loose workpieces using a vise or clamps

(not included) to prevent movement while working.

5. Verify that there are no utility lines or hardware in or near the workpiece.

This is especially critical for plunge cuts.

General Operating Instructions

1. Make sure that all guards are in place and in proper working order and that all adjustment knobs are tight before operation.

Do NOT operate Saw without blade guard or if blade guard is broken or not operating properly.

2. Use the Lubrication Unit when cutting Aluminium,

Copper, Stainless Steel and Cast Iron.

These materials can soften and stick to the blades.

3. Before starting a cut, draw a guideline along the desired line of cut.

4. Place the front edge of the saw blades on that part of the workpiece that is solidly supported.

5. Do NOT place the saw on the part of the workpiece that will fall off when the cut is made.

6. Slide the power switch forward to start the saw.

Let the blades reach full speed before beginning cut.

WARNING! Closely observe position of

saw’s housing during cut. Do not let housing bump up against material being cut.

Cutting Capacities up to 1″ up to 1″

Steel Pipe up to 1″

Corrugated Sheet Standard Thickness

Sheet Steel

Sheet Aluminum

Oak Wood up to 14 gauge up to 1/8″ up to 3/4″

7. Cut using steady, even pressure.

Do NOT force the Saw. Forcing the saw causes rough cuts and could shorten the life of the saw or cause kickback.

NOTE: THIS SAW WORKS BEST FOR SHORT CUTS.

For cuts longer than 6″, it is especially important to follow the feed speed recommendations below, and stop the cut or feed more slowly if the motor starts slowing down during the cut or if the blades start separating.

For materials thicker than 1/16″, cuts longer than 6″ are not recommended.

8. Feed blade straight into the cut.

Feeding at an angle can damage the blade teeth.

9. To prevent accidents, turn off the tool and disconnect its power supply after use. Clean, then store the tool indoors out of children’s reach.

Feed Speed

Correct feed speed is determined by the hardness and the thickness of the material being cut.

See following pages for how to cut certain cross sections.

In thin materials, feed the blades down with the teeth protruding. Then move forward (or backward) for cutting.

1. If the feed speed is too slow: a. The blades will only press down the material instead of cutting it.

b. The blade edges will glide and wear down the material.

c. This will cause a poor cut and will cause excessive wear on the blades.

2. If the feed speed is too fast: a. The cut may split or splinter the workpiece.

b. This will result in a poor cut with significant discharge on the lower side of the material.

c. If feed speed is not slowed, the split will grow bigger, potentially leading to serious injury and property damage.
