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 PSI Maximum
This tool is designed to operate at an air pressure of 90
pounds per square inch gauge pressure (90 PSI)
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: THEAIR SUPPLY SHOULD BE CLEAN, DRYAND
PREFERABLY LUBRICATED. FOR BEST RESULTS
DRAIN THE MOISTURE FROM YOUR COMPRESSOR
DAILY.
Use Only Power Sockets & Accessories
Sockets and accessories used shall be of the power
socket type. Always check sockets, retainers and
drives regularly for wear or damage and replace when
necessary.

If this Craftsman tool fails to give complete satisfaction
within one year from the date of purchase, RETURN IT
TO THE NEAREST SEARS STORE IN THE UNITED
STATES, and Sears will repair or replace it free of charge.
If this Craftsman tool is used for commercial or rental

[, WARNINGJ
Some dust created by power sanding, sawing, grinding,
drilling and other construction activities contains chemi-
cals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals
are:
Lead from lead based paint
crystalline silica from bricks and cement
and other masonry products, and
arsenic and chromium from chemically-
treated lumber.
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 par-
ticles.

Pre-Operation
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 5-10 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 accidently
engaged.
Installation (See figure 1)
This tool is designed to operate at 90 psi. Lower pres-
sure (below 90 psi) will reduce performance of the tool
while higher air pressure (over 90 psi) raises the perfor-
mance of the tool beyond its rated capacity and could
cause serious damage to tool and user.
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.
A 3/8" air hose is required up to a length of 8 ft. If more
length is required a 1/2" air hose should be used at the
compressor. Attach a 3/8" whip hose for the remaining
4 - 8 ft. for flexibility. Be sure all hoses and fittings are the
correct size and tightly secured before using air tool.

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.

Troubles ooting
Tool runs slowly or will not operate 1. rit or gum in tool 1. Flush the tool with air tool oil or gum
solvent•
2. No oil in tooI
3. Low air pressure
4. Air hose leaks
5. Pressure drops
• Worn rotor blade in motor
7. Worn ball bearing in motor
2. Lubricate the tool according to the lubrication
instructions in this manuai
3. a. Adjust the regulator on the tool to the maxi
mum setting
b. Adjust the compressor regulator to tool
maximum of 90 psi.
4. Tighten and seal hose fittings if leaks are found
use teflon tape.
5. a. Be sure the hose is the proper size. Long
hoses or tools using large volumes of air may
require a hose with an I.D. of 1/2" or larger
depending on the total length of the hose
b. Do not use a multiple number of hoses
connected together with quick connect fittings•
This causes additional pressure drops and
reduces the tool power• Directly connect the
hoses together
Replace rotor blade
7. Remove and inspect bearing for rust, dirt and
grit. Replace or clean and grease bearing with
bearing grease
Moisture blowing out of tool exahust 1. Water in tank 1. Drain tank. (See air compressor manual)• Oil tool
and run until no water is evident• Oil tool again and
run 1 2 seconds
Impacts slowly or will not impact 1. Lack of lubrication 1. Lubricate the air motor and the impact mechanism•
(See Lubrication section of this manual)
2. Adjust the regulator on the tool to the maximum
setting
2. Tool regulator set in wrong
position
3. In line regulator or
compressor regulator
set too low
3. Adjust regulators in the air system
Impacts rapidly but 1. Worn impact mechanism 1. Replace worn impact mechanism components
will not remove bolts
Does not impact 1. Broken impact mechanism 1. Replace broken impact mechanism components
