READ THIS MANUAL CAREFULLY BEFORE INSTALLING,
OPERATING OR SERVICING THIS EQUIPMENT.
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
Pneumatic tools should always be installed and used in accor-
dance with A.N.S.I. B186.1 “Safety Code For Portable Air Tools.”

Operate this tool at 90 p.s.i.g. (6.2 bar) maximum air pressure
at the air inlet of the tool.
Disconnect air supply from tool before removing/installing bit,
socket or device attached to tool or performing maintenance
procedures.
Keep hands, clothing and long hair away from rotating end of
tool.
Anticipate and be alert for sudden changes in motion during
start up and operation of any power tool.
Never exceed rated r.p.m. of tool.
Wearsuitable eye and hearing protection while operating tool.
Tool shaft can continue to rotate briefly after throttle is re-
leased.
Donot lubricate tools with flammable orvolatile liquids such as
kerosene, diesel or jet fuel.
Do not remove any labels. Replace any damaged label.
Use only accessories recommended by ARO.
Repeated prolonged operator exposure to vibrations which may
be generated in the use of certain hand-held tools may produce
Raynaud’s phenomenon, commonly referred to as Whitefinger
disease. The phenomenon produces numbness and burning
sensations in the hand and may cause circulation and nerve dam-
age as well as tissue necrosis. Repetitive users of hand-held
tools who experience vibrations should closely monitor duration
of use and their physical condition.
The use of other than genuine ARO replacement pans may
result in safety hazards, decreased tool performance and in-
creased maintenance and may invalidate all warranties.
ARO is not responsible for customer modification of tools for
applications on which ARO was not consulted.
Tool maintenance and repair should be performed by autho-
rized, trained, competent personnel. Consult your nearest
ARO authorized servicenter.
It is the responsibility of the employer to place the information
in this manual into the hands of the operator.

ROUTINE LUBRICATION REQUIREMENTS M30
55
Lackoforan excessive amount of lubrication will affect the perfor-
mance and life of this tool. Use only recommended lubricants at
below time intervals:
EVERY 8 HOURS OF TOOL OPERATION - Fill lubricator reser-
voir of recommended F.R.L.with spindle oil (29665). Ifan in line or
air line lubricator is not used, apply several drops of spindle oil
(29665) in air inlet.
EVERY 180 HOURS OF TOOL OPERATlON - Lubricate clutch
parts with molybdenum grease (46636-1). Lubricate gearing.
Pack bearings, coat shafts and lubricate gears with NLGI #1 “EP”
grease (33153). Gearing should contain approximately 3/64 oz.
(1.3 g) of grease for single reduction and 1/16 oz. (1.8 g) for
double reduction. Clutch should contain approximately l/l 6 oz.
(1.6 g) of grease.
AIR SUPPLY REQUIREMENTS
Formaximum operating efficiency, the following air supply specifi-
cations should be maintained to this air tool:
l AIR PRESSURE - 90 p.s.i.g. (6.2 bar)
AIR FILTRATION - 50 micron
. LUBRICATED AIR SUPPLY
l HOSE SIZE - 5/16” (8 mm) I.D.
An ARO@model C28231-810 air line FlLTER/REGULATOR/LU-
BRICATOR (F.R.L.) is recommended to maintain the above air
supply specifications.
RECOMMENDED LUBRICANTS
After disassembly iscomplete, all parts, except sealed orshielded
bearings, should be washed with solvent. To relubricate parts, or
for routine lubrication, use the following recommended lubricants:
Where Used
Air Motor 1 qt Spindle Oil
“0” Rings & Lip Seals 36466 4 oz. Stringy Lubricant
Gears and Bearings 33153 5lb.“EP"- NLGI#1Grease
Clutches 40036-1 1lb.“EP”MolybdenumDisulfide
INSPECTION,MAINTENANCE AND INSTALLATION
Disconnect air supply from the tool or shut off air supply and ex-
haust (drain) line of compressed air before performing mainte-
nance or service to the tool.
It is important that the tools be serviced and inspected at regular
intervals for maintaining safe, trouble-free operation of the tool.
Be sure the tool is receiving adequate lubrication, as failure to lu-
bricate can create hazardous operating conditions resulting from
excessive wear.
Be sure that the air supply lines and connectors are of proper size
to provide a sufficient quantity of air to the tool.
Tool maintenance and repair shall be performed by authorized,
trained, competent personnel. Tools, hose and fittings shall be re-
placed if unsuitable for safe operation and responsibility should
beassigned to besure that all tools requiring guards orother safe-
ty devices shall be kept in legible condition. Maintenance and re-
pair records should be maintained on all tools. Frequency of
repair and the nature of the repairs can reveal unsafe application.
Scheduled maintenance by competent authorized personnel
should detect any mistreatment or abuse of the tool and worn
parts. Corrective action should be taken before returning the tool
for use.
Disassembly should be done on a clean work bench with a clean
cloth spread to prevent the loss of small parts. After disassembly
iscompleted, all parts should bethoroughly washed in aclean sol-
vent, blown dry with air and inspected for wear levels, abuse and
contamination. Double sealed or shielded bearings should never
be placed in solvent unless a good method of m-lubricating the
bearing is available. Open bearings may be washed but should
not be allowed to spin while being blown dry.
Upon reassembling, lubricate parts where required. Use 33153
grease, or equivalent, in bearings. Use 36460 lubricant for “0”
ring assembly. When assembling “0” rings or parts adjacent “0
rings, care must be exercised to prevent damage to the rubber
sealing surfaces. A small amount of grease will usually hold steel
balls and other small parts in place while assembling.
When replacement parts are necessary, consult drawing contain-
ing the part for identification.
Always use clean, dry air. Dust, corrosive fumes and/or excessive
moisture can damage the motor of an air tool. An air line filter can
greatly increase the life of an air tool. The filter removes rust,
scale, moisture and other debris from the air lines. Low air pres-
sure (less than 90 p.s.i.g.) reduces the speed of the air tool. High
air pressure (more than 96 p.s.i.g.) raises performance beyond
the rated capacity ofthe tool and could cause injury. Shown below
is a typical piping arrangement.
