WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known 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 and other masonry
products, and
• 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 specially designed to filter out microscopic particles.

accessories during andafter use. Gloves will
reduce the risk of cuts or burns.
• Keep away from reciprocating end of tool. Do not wear
jewelry or loose clothing. Secure long hair. Scalping
can occur if hair is not kept away from tool and
accessories. Choking can occur if neckwear is not
kept away from tool and accessories.
• Do not use (or modify) the tool for any other purpose
than that for which it was designed without consulting
the manufacturer's authorized representative.
• Never use a chisel as a handstruck tool. They are
designed and heat treated to be used only in air
hammers. Select the correct shank and retainer for the
tool.
• Never operate tool without chisel retainer.

AIR SUPPLY
Tools of this class operate on a wide range of air pressures.
It is recommended that air pressure measures 90 psig at the tool
with the trigger fully depressed and no load applied to the tool. Higher
pressure (over 90 psig; 6.2 bar) raises performance beyond the rated
capacity of the tool, which will shorten tool life and could cause injury.
Always use clean,dry air. Dust,corrosive fumes and/or water in the air line
will cause damage to the tool. Drain water from air lines and compres-
sor prior to running tool daily. Clean the air inlet filter screen weekly. The
recommended hookup procedure can be viewed in the above figure.
The air inlet used for connecting air supply has standard 1/4" NPT. Line
pressure should be increased to compensate for unusually long air
hoses (over 25 feet). Minimum hose diameter should be 3/8" I.D. and
fittings should have the same inside dimensions and be tightly secured.
Ensure an accessible emergency shut off valve has been installed in the
air supply line and make others aware of its location.
Ensure an accessible emergency shut off valve has been installed in the
air supply line and make others aware of its location.
LUBRICATION
Lubricate the air motor daily with high quality air tool oil. If no air line
oiler is used, run 1/2 oz. of oil through the tool. The oil can be squirted
into the tool air inlet or into the hose at the nearest connection to the air
supply, then run the tool. A rust inhibitive oil is acceptable for air tools.
After an air tool has been lubricated, oil will discharge through the
exhaust port during the first few seconds of operation. The exhaust port
must be covered with a towel before applying air pressure to prevent
serious injury.
OPERATION
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any
accessory on this tool, or before performing any maintenance on this
tool.
Always place a chisel in the hammer and hold the tool down to the work
before operating. Damage to the tool or the retainer may result if this
precaution is not followed.
The chisel retainers are not designed for complete safety against
accidental release of chisels or hammers. To avoid injury, the
throttle must never be depressed unless the chisel is held firmly against
the work place. When tool is not in actual use, the chisel must be removed.
When using tool, regulate the speed so that the chisel is not being driven
out of the cylinder. If piston is allowed to strike the cylinder wall, internal
damage will result.
To change chisel, pull back on spring hook and insert chisel. Release
spring hook.
To regulate air, turn air regulator knob out for maximum air pressure and
in for minimum.
Use the simplest possible tool-to-socket hook up. Every connection
absorbs energy and reduces power.
NOTE: During operation, safety goggles must always be worn to
guard against flying debris (users and bystanders).
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,
moisture or restrictions in air pipes or the use of hose connec-
tions of improper size or poor conditions may reduce air supply.
Grit or gum deposits in the tool may cut power and may be cor-
rected by cleaning the air strainer and flushing out the tool with gum
solvent oil or an equal mixture of SAE #10 and kerosene. If outside
conditions are in order, disconnect tool from hose and take tool to your
nearest authorized service center.
