FULL TWO YEAR WARRANTY ON
CRAFTSMAN AIR-DRIVE TOOLS
If this Craftsman tool fails to give complete satisfaction
within two years from the date of purchase, RETURN IT
TO THE NEAREST SEARS STORE IN THE UNITED

Read Operating instructions
Please become familiar with all the instructions and
warnings before operating any pneumatic tool.
Always Wear Approved Eye Protection
Impact resistant eye protection should meet or exceed
the standards set forth in ANSI Z87.1, Occupational and
Educational Eye and Face Protection. Look for marking
Z87.1 on your eye protection to ensure that it is an
approved style.
Hearing Protection is Recommended
Hearing protection should be used when the noise level
exposure equals or exceeds an 8 hour time-weighted
average sound level of 85dBA. Process noise, reflective
surfaces, other tools being operated nearby, all add to the
noise level in a given work area. If you are unable to
determine your noise level exposure, we recommend the
use of hearing protection.
Avoid Prolonged Exposure to Vibration
Pneumatic tools can vibrate during use. Prolonged
exposure to vibration or very repetitive hand and arm
movements can cause injury. Discontinue the use of any
tool if you experience tingling, numbness, discomfort or
pain in your hands or arms. You should consult your
physician before resuming use of tool.
90 PSiG Maximum
This tool is designed to operate at an air pressure of 90
pounds per square inch gauge pressure (90 PSIG)
maximum, at the tool. Use of higher air pressure can, and
may cause injury. Also, the use of higher air pressure
places the internal components under loads and
stresses they were not designed for, causing premature
tool failure.
NOTE: THE AIR SUPPLY SHOULD BE CLEAN, DRY AND
PREFERABLY LUBRICATED. FOR BEST RESULTS
DRAIN THE MOISTURE FROM YOUR COMPRESSOR
DAIL_
Use Only Impact Sockets & Accessories
Sockets and accessories used shall be of the impact
socket type. Always check sockets, retainers and drives
regularly for wear or damage and replace when
necessary.

STATES, and Sears will repair it free of charge. If this
Craftsman tool is used for commercial or rental
purposes, this warranty applies for only 90 days from the
date of purchase. This warranty gives you specific legal
rights, and you may also have other rights which vary
from state to state.

Pre-Operation

[ WARNINGI

Before the tool is connected to the air supply, clear the air
hose of accumulated dust and moisture by running air
freely through the air hose for 5-19 seconds. Before
removing a tool for service or changing sockets, make
sure the air line is shut-off at the compressor. This will
prevent the tool from operating if the throttle is accidenfiy
engaged.
Installation
(See figure 1)

Some dust created by power sanding, sawing, grinding,
drilling and other construction activities contains chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals
are:

This tool is designed to operate at 99 psi. Lower pressure (below 90 psi) will reduce performance of the tool
while higher air pressure (over 90 psi) raises the performance of the tool beyond its rated capacity and could
cause serious damage to tool and user.

Lead from lead based paint
crystalline silica from bricks and cement
and other masonry products, and
arsenic and chromium from chemicallytreated lumber.

Always use clean dry air. Excessive moisture and dirt will
greatly reduce the life of any air motor. We recommend
the installation of an in-line filter-regulator-lubricator
as
close to the tool as possible.

Your risk from those 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 dust masks that
are specifically designed to filter out microscopic particles.

A 3/8" air hose is required up to
hose is required a 1/2" air hose
compressor. Attach a 3/8" whip
4 - 8 ft. for flexibility. Be sure all
correct size and tightly secured

a length of 8 ft. If more
should be used at the
hose for the remaining
hoses and fittings are the
before using air tool.

This ratchet is equipped with a lever throttle which
allows the operator to vary the speed.

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.

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).

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.

I ICAUTiONI
Excessive torque leverage above tool specifications
will result in premature gear wear.
