WARNINGS AND SAFETY RULES
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 lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids.
3.Keep bystanders, pets and children away. Children must never be allowed in the
work area. Do not let them handle machines, tools, extension cords, or air hoses.
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.
Always wear steel toe shoes when operating the Air Hammer.
7.Use eye and ear protection. Always wear ANSI-approved impact safety goggles and
ear protection. Wear a full face shield when breaking up concrete.
8.Do not overreach. Keep proper footing and balance at all times. Do not reach over
or across running machines or air hoses.
9.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 an authorized technician. The
handle must be kept clean, dry, and free from oil and grease at all times.

10.Disconnect air supply. Disconnect air hose when not in use.
11.Avoid unintentional starting. Be sure the trigger is not depressed when carrying the
Air Hammer.
12.Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
13.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 Air Hammer if the trigger does not turn on and off properly.
14.Guard against electric shock. Prevent body contact with grounded surfaces such
as pipes, radiators, ranges, and refrigerator enclosures.
15.Do not operate tool if under the influence of alcohol or drugs. Read warning labels
on prescriptions to determine if your judgment or reflexes are impaired while taking
drugs. If there is any doubt, do not operate the tool.
16.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.
17.For your safety, maintenance should be performed regularly by a qualified technician.
18.Use compressed air only Never use combustible gases as a power source.
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.
! 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:
A) Lead from lead-based paints;
B) Crystalline silica from bricks and cement or other masonry products;
C) Arsenic and chromium from chemically treated lumber.
Your risk from exposure 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.)
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
Additional Safety Warnings
