GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

SAVE THESE 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.Grounded adapters/chargers must be plugged into an outlet properly in stalled 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 Adapter/Charger should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.

5.Double insulated tools are 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.

6.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.

7.Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

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 immedi- ately. 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 oper- ating a power tool. Do not use a power tool while tired or under the influ- ence of drugs, alcohol, or medication. A moment of inattention while operat- ing 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 Trigger is off before plugging in. Carrying power tools with your finger on the Trigger, or adding a battery with the Trigger depressed, 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.

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 Trigger does not turn it on or off.

Any tool that cannot be controlled with the Trigger is dangerous and must be replaced.

19.Disconnect the Power Cord Plug from the power source before making any adjustments, changing batteries, or storing the Charger.

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 tools clean and bits sharp. Properly maintained tools and sharp bits 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 main- tained 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

1.Maintain labels and nameplates on the Hammer Drill. These carry impor- tant information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

2.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.

3.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.

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

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 remove the Battery Pack (14) before operation, inspection, maintenance, or cleaning procedures.

8.Know what you are drilling into. When drilling into a structure, make sure no electrical wires, cables, or plumbing is behind the surface.

9. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contain chemicals known (to the State of Cali- fornia) to cause cancer, birth defects or other reproductive harm. Some ex- amples 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.)

10. WARNING! People with pacemakers should consult their physician(s) before using this product. Electromagnetic fields in close proximity to a heart pacemaker could cause interference to or failure of the pacemaker.

In addition, people with pacemakers should adhere to the following:

-Avoid operating power tools alone.

-Don???t use a power tool with the power switch locked on.

-If powered via a power cord be certain that the tool is properly grounded. A ground fault interrupt (GFCI) system is also a good precaution. This inexpensive device is a good safety measure because it prevents a sustained electrical shock.

-Properly maintain and inspect all tools before use to avoid electrical shock.

GROUNDING

WARNING!

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

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 elec- tric 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.)

FIGURE A

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS

4.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.)

5.Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.)

FIGURE B

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 Figure C, next page.)

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 Figure C.)

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 Figure C.)

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 Figure C.)

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.

OPERATING INSTRUCTIONS

NOTE: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram on page 15.

Battery Pack (14) and Adapter (20) Use

1.Plug the Adapter power cord into an outlet. When the Adapter (20) is plugged in, but not connected to the battery, both lights should be lit (if this is not happening exchange the adapter). When the battery is connected only the red light should be

lit. When the battery is fully charged the red light should go out and the green light should come on. This may take up to 5 hours

2.Slide the Adapter into the slot on the top of the Battery Pack (14) until it clicks into place. To remove the Adapter, press the release button on the Battery Pack (14) and slide the Adapter (20) out. The Battery Pack (14) needs an initial charge of approximately 5 hours. After the initial charge, recharge the unit for approximately 3 to 5 hours. Never charge the battery more than 5 hours. See FIGURES 1 and 3.

3.To check the power level on the Battery Pack (14), press the TEST button on the Battery Pack (14). See FIGURE 2. Always after charging, use the TEST button to make sure a fully lit green light is on, showing a fully charged battery. When pushing the TEST button, if the lights are partially lit, that indicates a partial charge. When fully lit, Red = low charge, Yellow = 1/2 charge, Green = Full Charge. Test the Battery Pack periodically during operation and charge as needed.

Note: These lights show the approximate level of charge.

4.To load the Battery Pack (14) onto the Hammer Drill, just slide it along the bottom of the Base (13/17) until it clicks into place. Press the release button to remove the Battery Pack (14). See FIGURE 3.

Battery Pack (14)

NOTE: Always switch to a fresh battery when tool performance begins to diminish. Severe heat is most destructive to a battery; the more heat generated, the faster the battery loses power. A battery that gets too hot can be permanently damaged. Never over-discharge a battery by continuing to pull the tool trigger. When tool performance begins to diminish, stop the tool, recharge the battery, and use a fresh battery for opti- mal performance.

1.CAUTION: Always make sure the Battery Pack (14) is not attached to the Hammer

Drill prior to making any adjustments and adding or removing bits to the tool.

2.Determine the size bit you will use. With one hand, hold the rear section of the Chuck (1) firmly. With the other hand, turn the front section of the Chuck (1) counterclockwise to loosen the Chuck (1) and open the Jaws. See FIGURE 4.

Insert the non-cutting end of the bit into the Jaws at least 1/4???. Holding the rear section of the Chuck (1) firmly, turn the front section of the Chuck (1) clockwise to tighten the Chuck (1) and close the Jaws. Make sure the bit is securely held in the

Jaws of the Chuck (1) by putting on a thick work glove and pulling on the bit.

ASSEMBLY AND OPERATING INSTRUCTIONS (Continued)

3.Set the speed by adjusting the Variable Speed Switch (5) to either 1 (low) or 2 (high).

High speed is generally used for drilling applications and low speed is generally used for screw driving applications. See FIGURE 5.
