IMPORTANT SAFETY INFORMATION

General Power Tool Safety Warnings

MAINTENANCE

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

atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

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.

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.

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.

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 personal protective 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, 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.

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.

OPERATION

MAINTENANCE

SAFETY

SETUP

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 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.

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 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.

OPERATION

MAINTENANCE

1.Wear ear protectors with rotary hammers.

Exposure to noise can cause hearing loss.

2.Use auxiliary handles supplied with the tool.

Loss of control can cause personal injury.

3.Hold power tools 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 make exposed metal parts of the tool ???live??? and shock the operator.

4.Let bit cool before touching, changing or adjusting it. Bits heat up dramatically while in use, and can burn you.

5.If the drill bit jams, release the trigger immediately; drill torque can cause injury or break bit.

6.Maintain labels and nameplates on the tool. These carry important safety information.

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

7.Avoid unintentional starting.

Prepare to begin work before turning on the tool.

8.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.

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

10.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.

11.This product is not a toy.

Keep it out of reach of children.

12.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.

13.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 and 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.)

14.WARNING: The cord of this product contains 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.)

15.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.

SAFETY

Vibration Safety

SETUP

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 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.

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

3.Wear suitable gloves to reduce the vibration effects on the user.

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

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

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

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

OPERATION

SAFETY

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.

SETUP

OPERATION

MAINTENANCE

Grounded Tools: Tools with Three Prong Plugs

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.)

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 electric shock. (See 3-Prong Plug and Outlet.)

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.

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 on page 7.)

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.
