General Power Tool Safety Warnings

WARNING 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 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 grounded power tools. Unmodified plugs

and matching outlets will reduce risk of electric shock.

b. 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.

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. Safety

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

these devices can reduce dust-related hazards.

h. 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 NIOSHapproved for the specific hazards in the

work area.

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 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.

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. 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.

6. 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.

Drill and Impact Drill

Safety Warnings

1. Wear ear protectors with impact drills.

Exposure to noise can cause hearing loss.

Page 3For technical questions, please call 1-888-866-5797.Item 98179

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

5. Avoid unintentional starting. Prepare to begin work before turning on the tool.

6. 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.

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

8. 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.

9. This product is not a toy. Keep it out of reach of children.

10. 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.

11. 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.)

12. WARNING: The cord of this product contains lead and/or di (2-ethylhexyl) phthalate (DEHP), chemicals 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.)

13. 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.
