Initial tightening and loosening of fasteners should be
done manually with the ratchet being used as a hand
tool. Fasteners maythen be run on and off with
relative ease.
During use keep socket firmly against work surface to
avoid dislodging the socket from the anvil. Direction
control is located on the back of the ratchet head
(Fig 2).

Disconnect tool from air supply before servicing
or changing sockets.
Lubrication
An in-line fitter-regulator-lubricator (fig 1) is
recommended as it increases tool life and keeps the
tool in sustained operation. The in-line lubricator should
be regularly checked and filled with air toot oil. Proper
adjustment of the in-line lubricator is performed by
placing a sheet of paper next to the tools exhaust
ports and holding the throttle open approximately 30
seconds. The lubricator is properly set when a light
stain of oil collects on the paper. Excessive amounts of
oil should be avoided.
In the event that it becomes necessary to store the
tool for an extended period of time (overnight, weekend,
etc.), it should receive a generous amount of
lubrication through the air inlet (fig 2). The tool should
be run for approximately 30 seconds to ensure oil has
been evenly distributed throughout the tool. The tool
should be stored in a clean and dry environment.
Recommended lubricants:
Use air tool oil orany
other high grade turbine oil containing moisture
absorbent, rust inhibitors, metal wetting agents and an
EP (extreme pressure) additive. (See Fig. 2 for
location/air inlet).
