GENERAL SAFETY RULES

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS

Failure to follow all instructions listed in this manual

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.

SKU 93853 For technical questions, please call 1-800-444-3353 PAGE 2

REV 06/06

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 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.

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 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

SKU 93853 For technical questions, please call 1-800-444-3353 PAGE 3

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. 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.

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

SKU 93853 For technical questions, please call 1-800-444-3353 PAGE 4

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 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 Demolition Hammer. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

2. Always wear ANSI-approved safety impact eye glasses and a full

face shield when using the Demolition Hammer. Also wear heavy duty steel-toe boots, hearing protection, dust mask or respirator, and heavy duty work gloves. Using personal safety devices reduce the risk for injury.

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. Avoid unintentional starting. Make sure you are prepared to begin work before turning on the Demolition Hammer.

SKU 93853 For technical questions, please call 1-800-444-3353 PAGE 5

5. Do not force the Demolition Hammer. This tool will do the work better and safer at the speed and capacity for which it was designed.

6. WARNING! Keep hands, fingers, and feet safety away from the cutting

area.

7. Never leave the Demolition Hammer unattended when it is plugged into an electrical outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.

8. Before using the Demolition Hammer, check to make sure the Chisel is properly mounted in the Slider of the tool. Make sure the Chisel is sharp, and is not cracked or bent.

9. Industrial applications must follow OSHA guidelines.

10. Always hold the Demolition Hammer with both hands by its insulated

gripping surfaces; this offers protection against electrical shock, if the tool’s Chisel contacts hidden wiring or its own Power Cord.

11. Do not drill or break into existing walls, floors, or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses

or circuit breakers feeding the worksite.

12. Use a metal detector to determine if there are gas or water pipes hidden in

the work area or call the local utility company for assistance before beginning the operation. Striking or cutting into a gas line will result in

explosion. Water entering an electrical device may cause electrocution.

13. Position yourself to avoid being caught between the Demolition Hammer or Auxiliary Handle and walls or posts. Should the Chisel become bound or jammed in the work, the reaction of the tool could crush your hand or leg.

14. Do not strike the Chisel with a handheld hammer or sledge hammer when attempting to dislodge a bound or jammed Chisel. Fragments of metal from the Chisel could dislodge and strike you or bystanders.

15. Never place the Demolition Hammer down until the Motor has come to a

complete stop.

16. The Chisel may become hot after prolonged use. When removing the Chisel from the tool, avoid contact with skin and use proper protective gloves when grasping the Chisel.
