• 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.

Tools of this class 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 and unclean air will shorten tool life and may create a
hazardous condition.
Water in the air line will cause damage to the tool. Drain water
from air lines and compressor prior to running tool. Clean the air
inlet filter screen weekly. The recommended hook-up procedure
can be viewed in Figure 1.
The air inlet (Figure 2), 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.

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 grade of air tool oil. If no
air line oiler is used, run 1/2 ounce of oil through the tool. The oil
can be squirted into the tool air inlet Figure 2, 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. Grease fitting on yoke and
ratchet housing occasionally to ensure proper lubrication of the
ratchet mechanism.
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.
