Important Information
Compatible Compressors: Guidelines for Proper Use and Operation
Be sure to use the proper air compressor with Mastercraft® air-powered tools. The compressor that
is being used must be able to supply the proper amount of pressure (PSI) to the tool. Verify that the
tool does not require more SCFM (Standard Cubic Feet per Minute) than the compressor can
deliver without running continuously.
General Use
This Mastercraft® Air-powered Ratchet features a light aluminium body and a steel angle head.
Exhaust is discharged to the front, and grips are ergonomically designed. This ratchet is designed
for automotive applications such as removing or replacing radiators and spark plugs, air condition-
ing system repairs, and water pump repairs. It is compact, and powerful enough to turn bolts in
confined spaces.
Air System
1.Always use clean, dry, regulated compressed air at 90 PSI.
2.Do not exceed the maximum and minimum pressures. Operating the tool at the wrong pressure
(too low or too high) will cause excessive noise or rapid wear.
3.Keep hands and other parts of the body away from the tool's discharge and working areas when
connecting the air supply.
4.It is recommended that a filter-regulator-lubricator be used, and that it be located as close to the
tool as possible (see Fig. I).
5.If a filter-regulator-lubricator is not installed, place up to 6 drops of air tool oil into the NPT
inlet plug before each use.
6.If a filter-regulator-lubricator is installed, keep the air filter clean. A dirty filter will reduce the air
pressure to the tool, which will cause a reduction in power, efficiency, and general performance.
7.For optimal performance, install a quick connector to the tool and a quick coupler on the hose, if
applicable.
8. Verify that all of the connections in the air supply system are sealed in order to prevent air from
leaking.

CAUTION
Do not use in conditions near or below freezing, the moisture in the air line may freeze
and prevent tool operation. Do not store tools in a cold weather environment to prevent frost or ice
formation on the tools operating valves and mechanisms that could cause tool failure. Store in a
dry place.

All air compressors contain maintenance parts that require periodic replacement. These
used parts, including air filters and used lubricating oil, may contain regulated substances that must
be disposed of in accordance with local, state, and federal laws and regulations.
