Rev. 06/17/16
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.
The Quick Change Chuck is designed to accept only 0 .401
"
diameter round
shank chisels . Always place the chisel in the hammer's quick 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 . During
operation, safety goggles should always be used to guard against flying
rust and chips . 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 should always be
worn to guard against flying debris (users and bystanders).
MT1724 LONG BARREL AIR HAMMER
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 FIG. 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.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
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.
LUBRICATION AND MAINTENANCE
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.
WARNING:
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.
