Air Supply - Matco Tools MT2854 Manual Del Usuario

OPERATION
The MT2854 3/8" ratchet is designed to fasten and unfasten
threaded fasteners while operating under recommended
conditions. Note the directional setting of the reversing lever
before depressing the throttle. Ensure body stance to be in
excellent balance and have full control of the tool before use. Be
fully alert as sudden reaction torques and directional changes
may unexpectedly occur. Be aware that air ratchets are not
torque wrenches or pry bars. Joints and fasteners requiring a
specific torque must be checked with a torque wrench as the final
step. Using the air ratchet while the power is in the "off" position,
to tighten or break-free fasteners, can irreversibly damage its
internal mechanism and will void any remaining warranty.
FEATURES
• Precise variable speed trigger for control.
• Two chamber exhaust system helps to reduce noise level (PATENT PENDING).
• 360 degree swivel exhaust allows user to direct air away from work.
• Precision forged ratchet yoke provides durable design to prevent head
• Compact crankshaft transmits power with low vibration.

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 below 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.
WARNING
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.

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.
NOTE: Actual torque on a fastener is directly related to joint
hardness, tool speed, condition of socket and the time the tool is
allowed to impact.
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 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 & 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.
