Operate this tool at 90 p.s.i.g. (8.2 bar) maximum air pressure
at the air inlet of the tool.
l
Disconnect air supply from tool before removing/installing bit
socket or device attached to tool or performing maintenance
procedures.
l
Keep hands, clothing and long hair away from rotating end of
tool.
0
Anticipate and be alert for sudden changes in motion during
start up and operation of any power tool.
a
Never exceed rated r.p.m. of tool.
l
Wear suitable eye and hearing protection while operating tool.
0
Tool shaft can continue to rotate briefly after throttle is released.
l
Do not lubricate tools with flammable orvolatile liquids such as
kerosene, diesel or jet fuel.

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 damage as well as tissue necrosis. Repetitive users of hand-held
tools who experience vibrations should closely monitor duration
of use and their physical condition.
l
The use of other than genuine ARO replacement parts may
result in safety hazards, decreased tool performance and increased maintenance and may invalidate all warranties.
l
ARO is not responsible for customer modification of tools for
applications on which ARO was not consulted.
l
Tool maintenance and repair should be performed by authorized, trained, competent personnel. Consult your nearest
ARO authorized servicenter.
l
It is the responsibility of the employer to place the information
in this manual into the hands of the operator.
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
I
Wear hearing protection when
operating this tool.
Turn off air supply and disconnect
.
air supply hose before installing,
removing or adjusting any
accessory on this tool, or before
performing any maintenance on
this tool.
Air powered tools can vibrate in
use. Vibration, repetitive motions
or uncomfortable positions may
be harmful to your hands and
arms. Stop using any tool if
discomfort, tingling feeling or
pain occurs. Seek medical advice
before resuming use.
I
A WARNING
Do not carry the tool by the hose.
Do not use damaged, frayed or
deteriorated air hoses and
fittings.
Do not overreach when operating
this tool. Keep body stance
balanced and firm.
Operate at 90 p.s.i.g.
(6.2 bar/620 kPa)
maximum air pressure.
NOTICE

ROUTINE LUBRICATION REQUIREMENTS
M30
33
Lack of or an excessive amount of lubrication will affect the performance and life of this tool. Use only recommended lubricants at
below time intervals:
EVERY 8 HOURS OF TOOL OPERATION - Fill lubricator reservoir of recommended F.R.L. with spindle oil (29665). If an in line or
air line lubricator is not used, apply several drops of spindle oil
(29665) in air inlet.
EVERY 160 HOURS OF TOOL OPERATION - Lubricate clutch
parts with molybdenum grease (400361). Lubricate gearing.
Pack bearings, coat shafts and lubricate gears with NLGI #1 “EP”
grease (33153). Gearing should contain approximately 1/8 oz.
(3.5 g) of grease per reduction.
AIR SUPPLY REQUIREMENTS
For maximum 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)
l
AIR FILTRATION - 50 micron
l
LUBRICATED AIR SUPPLY
l
HOSE SIZE - 5/16” (8 mm) I.D.
An ARO model C28231-810 air line FILTER/REGULATOR/LU-
BRICATOR (F.R.L.) is recommended to maintain the above air
supply specifications.
Tool maintenance and repair shall be performed by authorized,
trained, competent personnel. Tools, hose and fittings shall be replaced if unsuitable for safe operation and responsibility should
be assigned to be sure that all tools requiring guards or other safety devices shall be kept in legible condition. Maintenance and repair 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
is completed, all parts should be thoroughly washed in a clean 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 “O”
ring assembly. When assembling “O” rings or parts adjacent “O”
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.
RECOMMENDED LUBRICANTS
After disassembly is complete, all parts, except sealed or shielded
bearings, should be washed with solvent. To relubricate parts, or
for routine lubrication, use the following recommended lubricants:
Where ARO Description
Air Motor 29665
“O” Rings & Lip Seals 36460
Gears and Bearings 33153
Clutches 40036-1
1 qt Spindle Oil
4 oz. Stringy Lubricant
5 lb. “EP” - NLGI #1 Grease
1 lb. “EP” Molybdenum Disulfide
INSPECTION, MAINTENANCE AND INSTALLATION
Disconnect air supply from the tool or shut off air supply and exhaust (drain) line of compressed air before performing maintenance 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.
.
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 pressure (less than 90 p.s.i.g.) reduces the speed of the air tool. High
air pressure (more than 90 p.s.i.g.) raises performance beyond
the rated capacity of the tool and could cause injury. Shown below
is a typical piping arrangement.
