WARNING: DISCONNECT TOOL FROM AIR
SUPPLY BEFORE SERVICING OR CHANGING
SOCKETS. This air ratchet is equipped with a lever
throttle which allows the operator to vary the speed.
Direction control is located on the back of the ratchet
head. Initial tightening and loosening of fasteners
should be done manually with ratchet used as a hand
tool. Nuts may then be run on an 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 tool specifica-
tions will result in premature gear wear.
WARNING:SOME DUST CREATED BY POWER
SANDING, SAWING, GRINDING, DRILLING, AND
OTHER CONSTRUCTION ACTIVITIES CONTAINS
CHEMICALS KNOWN TO CAUSE CANCER, BIRTH
DEFECTS OF REPRODUCTIVE HARM, SOME
EXAMPLES OF THESE CHEMICALS ARE:
e Lead from lead-based paints
« Crystalline silica from bricks, cement and other masonry
products
e Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals, work in a well ventilated area and work
with approved safety equipment such as those dust masks
MAINTENANCE
Lubrication
An automatic in-line filter-regulatorlubricator 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
exhaust ports and holding the throttle open approxi-
mately 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 at that time. 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 too! oil or any
other high grade turbine oil containing moisture
absorbents, rust inhibitors, metal wetting agents
and an EP (extreme pressure) additive.
