Matco Tools MT2812 Manual page 3

OPERATION
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 .
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.
AIR SUPPLY
Tools of this class operate on a wide range of air pressures. It is
recommended that max. air pressure of these tools measures 90 PSI at the
tool while running free. Higher pressure and unclean air will shorten tool life
because of faster wear and may create a hazardous condition.
Water in the air line will cause damage to the tool. Drain the air tank daily. Clean
the air inlet filter screen on at least a weekly schedule. The recommended
hook-up procedure can be viewed in Figure 1 .
WARRANTY
Matco warrants its air tools for a period of 1 year to the consumer. We will
repair any MT Series air tool covered under this warranty which proves to be
defective in material or workmanship during the warranty period. In order
to have your tool repaired, return the tool to either of the Matco Authorized
Warranty Centers listed to the right, freight prepaid. Please include a copy of
your proof of purchase and a brief description of the problem. The tool will
be inspected and if any part or parts are found to be defective in material or
workmanship, the tool will be repaired free of charge and returned to you
freight prepaid.
This warranty gives you specific rights. You may also have other rights which
vary from state to state.
The foregoing obligation is Matco's sole liability under this or any implied
warranty and under no circumstances shall Matco be liable for any incidental
or consequential damages .
Note: Some states do not allow the exclusion or limitation of
incidental or consequential damages so the above limitation or exclusion may
not apply to you.
MT2812
MT2812 Medium Barrel Air Hammer
FEATURES
• Quickly change chisel blades with the Matco exclusive chuck.
• Shock absorption for the technician provided by the vibration dampening system.
• Maximum comfort with the ergonomic handle design.
• 20% more power over standard air hammers with the Matco new air flow design.
• Have total control on the workpiece with tip valve variable speed throttle.
The air inlet used for connecting air supply has standard 1/4" NPT
American Thread .
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 .
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. If outside conditions are in order, and the
tool still performs erratically, disconnect tool from hose and take tool to your
nearest Matco authorized service center .
LUBRICATION & MAINTENANCE
Lubricate the tool daily with a high quality of 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.
