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!

Keep work area clean. Cluttered areas invite injuries.

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 lighted. Do not use electrically

powered tools in the presence of ﬂammable gases or liquids.

Keep children away. Children must never be allowed in the work area. Do not let them

handle machines, tools, extension cords, or air hoses.

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.

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.

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

moving parts. Protective, electrically nonconductive clothes and nonskid footwear are

recommended when working. Wear restrictive hair covering to contain long hair.

Use eye and ear protection. Always wear ANSI-approved impact safety goggles.Wear

a full face shield if you are producing metal ﬁlings or wood chips.Wear an ANSI-approved

dust mask or respirator when working around metal, wood, and chemical dusts and

mists.

Do not overreach. Keep proper footing and balance at all times. Do not reach over or

across running machines or air hoses.

Maintain tools with care. Keep tools clean for better and safer performance. Follow

instructions for lubricating and changing accessories. Inspect tool cords and air hoses

periodically and, if damaged, have them repaired by a qualiﬁed technician. The handles

must be kept clean, dry, and free from oil and grease at all times.

Disconnect air supply. Disconnect air hose when not in use.

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

removed from the tool or machine work surface before plugging it in.

Avoid unintentional starting. Do not carry any tool while holding the trigger, whether

it is plugged in or not.

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

when you are tired.

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 ﬁxtures; and any other condition that may affect proper operation. Any part

that is damaged should be properly repaired or replaced by a qualiﬁed technician. Do

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

Guard against electric shock. Prevent body contact with grounded surfaces such as

pipes, radiators, ranges, and refrigerator enclosures.

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.

Do not operate tool if under the inﬂuence of alcohol or drugs. Read warning labels

if taking prescription medicine to determine if your judgement or reﬂexes are impaired

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

Use proper size and type extension cord. If an extension cord is required for the air

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

tool without heating up. Otherwise, the extension cord could melt and catch ﬁre, or cause

electrical damage to the tool. Check your compressor’s manual for the appropriate size

cord.

Note: Performance of the compressor (if powered by line voltage) may vary depending on

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

Maintenance. For your safety, maintenance should be performed regularly by a qualiﬁed

technician.

Compressed air only. Never use combustible gases as a power source.

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.
