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 GFCI 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 ANSI‑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 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.
   n. This product is not a toy.
   Keep it out of reach of children.
   o. 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.
   p. 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. Safety instructions for all operations
   a. use the auxiliary handle(s). Loss of control can cause personal injury.
   b. Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.
   c. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fasteners may contact hidden wiring or its own cord.
   Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
   d. Let bit cool before touching, changing or adjusting it. Bits heat up dramatically while in use, and can burn you.
   e. If the drill bit jams, release the Trigger immediately; drill torque can cause injury or break bit.

7. Safety instructions when using long drill bits a. never operate at higher speed than the maximum speed rating of the drill bit.
   At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
   b. always start drilling at low speed and with the bit tip in contact with the workpiece.
   At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
   c. apply pressure only in direct line with the bit and do not apply excessive pressure.
   Bits can bend causing breakage or loss of control, resulting in personal injury.

8. 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.
