IMPORTANT SAFETY INFORMATION

General Power Tool Safety Warnings
WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool.
Failure to follow all instructions listed below 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 or battery-operated (cordless) power tool.

  1. Work area safety
    a. Keep work area clean and well lit.
    Cluttered or dark areas invite accidents.
    b. 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.
    c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

  2. Electrical safety
    a. 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.
    b. 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.
    c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
    d. 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.
    e. 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.
    f. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCl reduces the risk of electric shock.

  3. Personal safety
    a. 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.
    b. 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.
    c. 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.
    d. 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.
    e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
    f. 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.
    g. 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.
    h. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles.
    A careless action can cause severe injury within a fraction of a second.
    i. 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 ANSIl-approved and breathing protection must be NIOSH-approved for the specific hazards in the work area.
    j. Avoid unintentional starting. Prepare to begin work before turning on the tool.
    k. 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.
    l. When using a handheld power tool, maintain a firm grip on the tool with both hands to resist starting torque.
    m. Do not depress the spindle lock when starting or during operation.
    n. 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.
    o. This product is not a toy. Keep it out of reach of children.
    p. 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 Trigger locked on.
    ♦ Properly maintain and inspect to avoid electrical shock.
    ♦ Properly ground power cord.
    Ground Fault Circuit Interrupter (GFCI) should also be implemented — it prevents sustained electrical shock.
    q. 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.

  4. Power tool use and care
    a. 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.
    b. 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.
    c. Disconnect the plug from the power source and/or remove the battery pack, if detachable, 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.
    d. 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.
    e. Maintain power tools and accessories. 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.
    f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
    g. 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.
    h. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

  5. Service
    a. 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.
    b. Maintain labels and nameplates on the tool. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

  6. Cutting procedures
    a. ADANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. /fboth hands are holding the saw, they cannot be cut by the blade.
    b. Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
    c. 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.
    d. Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. /tis important to support the work properly to minimise body exposure, blade binding, or loss of control.
    e. Hold the 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 could give the operator an electric shock.
    f. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
    g. 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 off-center, causing loss of control.
    h. 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.

  7. Kickback causes and related warnings
    – kickback is a sudden reaction to a pinched, jammed 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 jammed 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 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 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.
    b. 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 actions to eliminate the cause of blade binding.
    c. When restarting a saw in the workpiece, centre the saw blade in the kerf so that the saw teeth are not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the saw is restarted.
    d. Support large panels to minimise 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 the cut. /f blade adjustment shifts while cutting, it may cause binding and kickback.
    g. Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

  8. Lower guard function
    a. Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the 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.
    b. 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.
    c. The lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”. Raise the lower guard by the retracting handle and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.
    d. Always observe that the lower guard is covering the blade before placing the 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.

  9. 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:
    a. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical check-ups 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 symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.
    b. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury.
    c. Wear suitable gloves to reduce the vibration effects on the user.
    d. Use tools with the lowest vibration when there is a choice.
    e. Include vibration-free periods each day of work.
    f. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.
    g. 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. 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.
Grounded Tools: Tools with Three Prong Plugs

HERCULES HE72 714 Corded Circular Saw - Plug 3-Prong Plug and Outlet

  1. Tools marked with “Grounding Required” have athree 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 electric shock. (See 3-Prong Plug and Outlet.)
  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 3-Prong Plug and Outlet.)
  3. The 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 preceding illustration. (See 3-Prong Plug and Outlet.)

Double Insulated Tools: Tools with Two Prong Plugs

HERCULES HE72 714 Corded Circular Saw - Plug 2 Outlets for 2-Prong Plug

  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. 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 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.)
  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.

WARNING! To reduce the risk of serious injury, adjust the depth of cut to just barely clear the workpiece and remove shavings.
Adjusting Bevel

  1. Loosen the Bevel Lock Lever to allow the angle of cut to be adjusted.
  2. Tiltthe Base Plate to set the desired angle between 0 and 57 degrees, using the Bevel Scale as a guide. The Saw has pre-set detent stops at 22.5 and 45 degrees.
  3. After adjustment, tighten the Bevel Lock Lever.

Workpiece Set Up

  1. Workpiece selection:
    a. Workpiece must be wood, 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.
    Note: Use caution to avoid overheating the cutting tips.

  2. Secure loose workpieces using a vise or clamps (not included) to prevent movement while working.

  3. Refer to cutting capacities in the Specifications Table on page 6 for limitations on workpiece size.

General Instructions for Use

  1. Make all necessary adjustments to the Circular Saw.

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

  3. Make sure that the Trigger is in the off-position, then plug the Power Cord into the nearest 120 volt, grounded electrical outlet.

  4. Firmly grip the Main Handle with one hand and the Auxiliary Handle with the other hand.

  5. Pull and hold the Trigger to turn on the Saw.

  6. Allow the Saw Blade to reach full speed before contacting the workpiece

  7. Make straight cuts only. DO NOT twist Saw while cutting. If this occurs, the Saw Blade will “bind” in the workpiece causing kickback, potential injury, and/or damage to the workpiece and Circular Saw.

  8. Do not force the Saw to cut faster than it is designed to cut. Feed the Saw Blade gradually into the workpiece.

  9. Release Trigger if the Saw Blade is to be backed out of an uncompleted cut. The Saw is equipped with an electric brake designed to stop Blade rotation when the Trigger is released. Wait until the Saw Blade stops spinning before removing the Saw. Do not press against the Saw Blade to stop it.
