Matco Tools MT2859 Guide D'utilisation page 3

FEATURES
• New reinforced ergonomic shift knob design makes changing from forward to reverse easy.
• New added bearings on both sides of the gearing increases durability, tool life, as well as cuts
down on internal friction allowing the tool to run smoother.
• Rapid response variable speed trigger allows for one finger operation and unmatched control.
• Rotating side exhaust allows user to direct air away from work.
• One of the most powerful 1/2" ratchets on the market with 130 ft. lbs. of torque.
• Matco patented captured head and grease fitting.
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.

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.
