Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be

followed to reduce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Do not use machines or power tools in

damp or wet locations. Don’t expose to rain. Keep work area well lit. Do

not use electrically powered tools in the presence of ammable gases or

liquids.

3. Keep children away. Children must never be allowed in the work area. Do

not let them handle machines, tools, or extension cords.

4. Store idle equipment. When not in use, tools must be stored in a dry

location to inhibit rust. Always lock up tools and keep out of reach of

children.

5. Use the right tool for the job. Do not attempt to force a small tool or

attachment to do the work of a larger industrial tool. There are certain

applications for which this tool was designed. It will do the job better

and more safely at the rate for which it was intended. Do not modify this

tool and do not use this tool for a purpose for which it was not intended.

6. Dress properly. Do not wear loose clothing or jewelry as they can be

caught in moving parts. Protective, electrically non-conductive clothes and

non-skid footwear are recommended when working. Wear restrictive hair

covering to contain long hair.

7. Use eye and ear protection. Always wear ANSI approved impact safety

REV 07c

SKU 92880 For technical questions please call 1-800-444-3353 Page 3

goggles. Wear a full face shield if you are producing metal lings or wood

chips. Wear an ANSI approved dust mask or respirator when working around

metal, wood, and chemical dusts and mists.

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

reach over or across running machines.

9. Maintain tools with care. Keep tools sharp and clean for better and safer

performance. Follow instructions for lubricating and changing accessories.

Inspect tool cords periodically and, if damaged, have them repaired by an

authorized technician. The handles must be kept clean, dry, and free from oil

and grease at all times.

10. Disconnect power. Unplug battery from tool and charger/transformer from

power outlet when not in use.

11. Remove adjusting keys and wrenches. Check that keys and adjusting

wrenches are removed from the tool or machine work surface before plugging it

in.

12. Avoid unintentional starting. Be sure the switch is in the Off position when

not in use and before plugging in. Do not carry any tool with your hand on

the power switch, whether it is energized or not.

13. Stay alert. Watch what you are doing, use common sense. Do not operate

any tool when you are tired.

14. Take caution as some woods contain preservatives such as copper

chromium arsenate (CCA) which can be toxic. When cutting these

materials extra care should be taken to avoid inhalation and minimize skin

contact.

15. Check for damaged parts. Before using any tool, any part that appears

damaged should be carefully checked to determine that it will operate

properly and perform its intended function. Check for alignment and binding

of moving parts; any broken parts or mounting xtures; and any other

condition that may affect proper operation. Any part that is damaged should

be properly repaired or replaced by a qualied technician. Do not use the

tool if any switch does not turn On and Off properly.

16. Guard against electric shock. Prevent body contact with grounded

surfaces such as pipes, radiators, ranges, and refrigerator enclosures.

17. Replacement parts and accessories. When servicing, use only identical

replacement parts. Use of any other parts will void the warranty. Only use

accessories intended for use with this tool. Approved accessories are

available from Harbor Freight Tools.

SKU 92880 For technical questions please call 1-800-444-3353 Page 4

18. Do not operate tool if under the inuence of alcohol or drugs. Read

warning labels on prescriptions to determine if your judgment or reexes are

impaired while taking drugs. If there is any doubt, do not operate the tool.

19. Use proper size and type extension cord. If an extension cord is required,

it must be of the proper size and type to supply the correct current to the

charger without heating up. Otherwise, the extension cord could melt and

catch re, or cause electrical damage to the transformer or battery charger.

This item requires use of an extension cord of 0 to 10 amps capability (up

to 50 feet), with wire size rated at 18 AWG. Longer extension cords require

larger size wire. If you are using the products outdoors, use an extension

cord rated for outdoor use (signied by “WA” on the jacket).

20. Maintenance. For your safety, service and maintenance should be

performed regularly by a qualied technician.

21. Pacemaker safety warning. People with pacemakers should consult with

their physician(s) before using this product; operation of equipment in close

proximity to a heart pacemaker could cause interference or failure of the

pacemaker.

22. WARNING: The brass components of this product contain lead, a chemical

known to the State of California to cause birth defects (or other reproductive

harm). (California Health & Safety code 25249.5, et seq.)

23. 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

(California Health & Safety Code 25249.5, et seq. )

WARNING: Keep this tool and its attachments out of reach of children.

Small parts can easily be swallowed by children.

Note: Performance of the transformer and battery charger may vary depending

on variations in local line voltage. Extension cord usage may also affect tool

performance.

Warning: The warnings, cautions, 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.
