OPERATION
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any part or
accessory on this tool, or before performing any maintenance on this
tool.
Never operate the tool without a Chisel Retainer.
Never use a chisel as a hand struck tool. They aredesigned and heat
treated to be used only in air hammers. Select the correct shank and
retainer for the tool.
Never use dull, chipped or damaged accessories. Never cool a
hot accessory in water as brittleness and early failure can result.
Accessory breakage or tool damage may result from prying. Take
smaller bites to avoid getting stuck.
The Quick Change Chuck is designed to accept only 0.401" diameter
round shank chisels. Always place the chisel in the hammer's quick
AIR SUPPLY
Tools 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 the water from air lines and
compressor prior to running tool. Clean the air inlet filter screen weekly.
The recommended hookup procedure can be viewed in the Figure 1.
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.
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any part or
accessory on this tool, or before performing any maintenance on this
tool.
Ensure an accessible emergency shut off valve has been installed in the
air supply line and make others aware of its location.

Hose
change chuck retainer 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 quick change chuck collar and insert
chisel. Release chuck collar to lock in the chisel.
To regulate power, gently pull the variable speed trigger for minimum to
maximum 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 connections of improper size
or poor conditions may reduce air supply. Grit or gum deposits in the tool
may cut power and may be corrected 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.
