WARNING:
DISCONNECT TOOL FROM AiR SUPPLY
BEFORE SERVICING OR CHANGING SOCKETS. This
ratchet is equipped with a lever throttle which ailows the
operator to vary the speed. Direction control is located on
the back of the ratchet head. Initial tightening and loosen-
ing of fasteners should be done manually with ratchet
used as a hand tool. Fasteners may then be run on and
off with relative ease.
Keep socket firmly against work surface when running the
ratchet to avoid dislodging the socket from the anvil.
Excessive torque leverage above tooI specifications
will
result in premature gear wear.
Lubrication
An in-line filter-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 tool 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. The tool should be run for approximately 30
seconds to ensure oil has been evenly distributed through
out the tool. The tooI should be stored in a clean and dry
enviroment
Recommended
lubricants:
Use air tool oil or any other
high grade turbine oil containing moisture absorbent, rust
inhibitors, metal wetting agents and an EP (extreme
pressure) additive.
