wArning: some dust created by power sanding, sawing, grinding, drilling,
and other construction activities, contains 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
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 spe-
cially designed to filter out microscopic particles. (California Health & Safety Code
§ 25249.5, et seq.)

With the proper tool attached to the Air Hammer, attach your air supply to the Air
Inlet (7) at the base on the Housing (1). Turn on the air supply. Carefully place the
tool against the surface of the project you are working with. Make sure the project
is in a vise or attached to something that holds it securely so it cannot be moved
out of position.

3.
Set the Air Regulator (11) located at the base of the Housing (1). Air pressure
should not exceed 90 psi. test the action of the Air hammer and adjust the
Air regulator (11) as necessary.

you are working with. Easy, light pressure works best.

face shield and not just safety goggles to protect against Needles that may snap
off and could possibly cause personal injury.
