GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instruc-

tions listed below may result in electric shock, fire, and/or serious injury.

SAVETHESE INSTRUCTIONS

Work Area

1. Keep your work area clean and well lit. Cluttered benches and 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 bystanders, children, and visitors away while operating a power tool.

Distractions can cause you to lose control. Protect others in the work area from

debris such as chips and sparks. Provide barriers or shields as needed.

Electrical Safety

4. 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.

5. Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

6. Grounded tools must be plugged into an outlet properly installed and grounded in

accordance with all codes and ordinances. Never remove the grounding prong or

modify the plug in any way. Do not use any adapter plugs. Check with a qualified

electrician if you are in doubt as to whether the outlet is properly grounded. If the

tools should electrically malfunction or break down, grounding provides a low

resistance path to carry electricity away from the user.

7. This Double insulated Hammer Drill is equipped with a polarized plug (one blade is

wider than the other). This plug will fit in a polarized outlet only one way. If the plug

does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a

qualified electrician to install a polarized outlet. Do not change the plug in any way.

Double insulation eliminates the need for the three wire grounded power cord and

grounded power supply system.

8. Do not abuse the Power Cord. Never use the Power Cord to carry the tools or pull the

Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or

moving parts. Replace damaged Power Cords immediately. Damaged Power Cords

increase the risk of electric shock.

9. When operating a power tool outside, use an outdoor extension cord marked “W-A” or

“W”. These extension cords are rated for outdoor use, and reduce the risk of electric

shock.

Personal Safety

10. Stay alert. Watch what you are doing, and use common sense when operating a

power tool. Do not use a power tool while tired or under the influence of drugs,

alcohol, or medication. A moment of inattention while operating power tools may

result in serious personal injury.

11. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your

hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair

can be caught in moving parts.

12. Avoid accidental starting. Be sure the Power Switch is off before plugging in.

Carrying power tools with your finger on the Power Switch, or plugging in power tools

with the Power Switch on, invites accidents.

13. Remove adjusting keys or wrenches before turning the power tool on. A wrench or a

key that is left attached to a rotating part of the power tool may result in personal

injury.

Page 4SKU 45338

14. Do not overreach. Keep proper footing and balance at all times. Proper footing and

balance enables better control of the power tool in unexpected situations.

15. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety

shoes, hard hat, or hearing protection must be used for appropriate conditions.

Tool Use and Care

16. 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.

17. Do not force the tool. Use the correct tool for your application. The correct tool will do

the job better and safer at the rate for which it is designed.

18. Do not use the power tool if the Power Switch does not turn it on or off. Any tool that

cannot be controlled with the Power Switch is dangerous and must be replaced.

19. Disconnect the Power Cord Plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such preventive safety

measures reduce the risk of starting the tool accidentally.

20. Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

21. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained

tools with a sharp cutting edge are less likely to bind and are easier to control. Do not

use a damaged tool. Tag damaged tools “Do not use” until repaired.

22. Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the tool’s operation. If damaged, have the tool serviced

before using. Many accidents are caused by poorly maintained tools.

23. Use only accessories that are recommended by the manufacturer for your model.

Accessories that may be suitable for one tool may become hazardous when used on

another tool.

Service

24. Tool service must be performed only by qualified repair personnel. Service or

maintenance performed by unqualified personnel could result in a risk of injury.

25. When servicing a tool, use only identical replacement parts. Follow instructions in the

“Inspection, Maintenance, And Cleaning”

section of this manual. Use of unauthorized

parts or failure to follow maintenance instructions may create a risk of electric shock

or injury.

SPECIFIC SAFETY RULES FORTHE HAMMER DRILL

1. Hold tool by insulated gripping surfaces when performing an operation where

the cutting tools 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.

2. Maintain labels and nameplates on the Hammer Drill.These carry important

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

3. Always wear safety impact eye goggles and heavy work gloves when using the

Hammer Drill. Using personal safety devices reduce the risk for injury. Safety impact

eye goggles and heavy work gloves are available from Harbor Freight Tools.

4. Maintain a safe working environment. Keep the work area well lit. Make sure there is

adequate surrounding workspace. Always keep the work area free of obstructions,

grease, oil, trash, and other debris. Do not use a power tool in areas near flammable

chemicals, dusts, and vapors. Do not use this product in a damp or wet location.

5. Avoid unintentional starting. Make sure you are prepared to begin work before turning

on the Hammer Drill.

6. Do not force the Hammer Drill.This tool will do the work better and safer at the speed

and capacity for which it was designed.

7. Always unplug the Hammer Drill from its electrical outlet before performing and

inspection, maintenance, or cleaning procedures.

8. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities, contain 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.)

9. WARNING! People with pacemakers should consult their physician(s) before

using this product. Operation of electrical equipment in close proximity to a heart

pacemaker could cause interference or failure of the pacemaker.

10. Never leave the Hammer Drill unattended while running.Turn power off if you have to

leave the Hammer Drill.

11. Before each use, check all nuts, bolts, and screws for tightness.Vibration may cause

these to loosen.

GROUNDING

WARNING!

Improperly connecting the grounding wire can result in the risk of electric

shock. Check with a qualfified 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 removethe 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

facilitybefore use. If the plug will not fit the outlet,have a proper outlet installed

byaqualifiedelectrician.

Grounded Tools: Tools withThree Prong Plugs

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

Figure A.)

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 Figure A.)

3. Your 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 following illustration. (See Figure A.)

Double InsulatedTools:Tools withTwo Prong Plugs

4. This tool is double insulated.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. (See Figure B above.)

5. Double insulated tools may be used in either of the 120 volt outlets shown in the

following illustration. (See Figure B above.)

Figure A Figure B

Page 7SKU 45338

EXTENSION CORDS

Grounded

tools require a three wire extension cord.

Double Insulated

tools (like this

one) 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 your 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 your extension cords from sharp objects, excessive heat, and damp or wet

areas.
