WARNING
General Product Safety Information
Read and understand this manual before operating this product.
It is your responsibility to make this safety information available to others that will operate this product.
Failure to observe the following warnings could result in injury.
WARNING
Product Safety Information - When Placing the Product in Service
These motors are designed for gas operation at a maximum inlet pressure of 150 psig. It is not totally sealed in dynamic operation
since the exhaust must be vented or piped away and there is a possibility of leakage around the output shaft when rotating.
When assembling a gas operated motor always perform the steps as directed in the section titled Gas Operation Test Procedure.
Always operate, inspect and maintain this motor in accordance with American National Standards Institute Safety Code for Portable
Air Tools (ANSI B186.1).
For safety, top performance and maximum durability of parts, operate this motor at 150 psig (10.3 bar/1030 kPa) maximum air/gas
pressure at the inlet with 1/2”(13 mm) air/gas supply hose.
Always turn o the air/gas supply and disconnect the air/gas supply hose before installing, removing or adjusting any accessory on
this motor or before performing any maintenance on this motor.
Do not use damaged, frayed or deteriorated air hoses and ttings.
Do not lubricate motor with ammable or volatile liquids such as kerosene, diesel or jet fuel.
Do not remove any labels. Replace any damaged label.
WARNING
Product Safety Information - When Using the Product
Caution should be taken when operating this motor on gas because of the danger of re, explosion or inhalation.
Always wear eye protection when operating or performing maintenance on this product.
Always wear hearing protection when operating this product.
Anticipate and be alert for sudden changes in motion during start up and operation of any motor.
Keep hands, loose clothing and long hair away from rotating end of motor.
Motor shaft may continue to rotate briey after air/gas line is removed.
Use accessories recommended by Ingersoll Rand.
This motor is not insulated against electric shock.

Lubrication
Ingersoll Rand No. 28 Ingersoll Rand No. 20
Grease Oil
Always use an air line lubricator with this motor.
Installation and Operation
Air Supply and Connections
Always use clean, dry air at 150 psig maximum air pressure. Dust,
corrosive fumes and/or excessive moisture can ruin the motor of an
air tool. An air line lter can greatly increase the life of an air tool. The
lter removes dust and moisture. Make sure all hoses and ttings are
the correct size and are tightly secured.
WARNING
It is imperative that gas-operated motors be properly sealed
to prevent gas leakage. Refer to Gas Operation Test Procedure
when making repairs.

Maintenance
Gas Operation Test Procedure
Ingersoll Rand carefully assembled this motor with specially
selected sealing materials to prevent gas leakage, and tested this
motor to detect leaks.
When reassembling a motor, follow the procedures to properly test
the motor for leaks:
1. Plug one inlet (either forward or reverse).
2. Connect non-pressurized air line to the inlet that is not plugged.
3. Pressurize motor with air to 40 psi.
4. Fully submerge motor in water.
5. Monitor for a minimum of 2 minutes for bubbles in water.
6A. If the motor DOES NOT release bubbles during the two minute
test, the motor is ready for gas operation.
6B. If the motor releases ANY bubbles during testing, the motor must
be reworked and retested.
NOTICE
If the motor operates sluggishly, ush it with a clean,non-toxic,
nonammable commercial solvent in a well ventilated area.
To ush the motor:
1. Disconnect the air line and muer.
2. Pour 6 to 8 cc of solvent into each inlet.
3. Rotate the rotor shaft by hand in both directions several times to
ensure all internal parts of motor are thoroughly cleaned.
4. Apply air pressure to the inlet and slowly increase the air ow
until there is no trace of the solvent in the exhaust.
5. After ushing, shut o the air supply and disconnect air supply
line.
6. Pour 6 to 8 cc of a high detergent SAE 10 motor oil into the air
inlet.
7. Reconnect the air supply line, slowly increase the air pressure to
ensure all internal parts of motor will be covered with a lm of oil.
8. If the motor is still low in power, check for damaged vanes or
foreign material in the vane slots in the Rotor.
NOTICE
Periodically, check the Vanes for wear. Always replace Vanes in
sets, never replace an individual Vane.
Assembly / Disassembly Instructions
WARNING
Always wear eye protection when operating or performing
maintenance on this motor.
Always turn o air / gas supply and disconnect supply hose
before installing, removing or adjusting any accessory on this
motor, or before performing any maintenance on this motor.
Disassembly
General Instructions
1. Always disconnect the air / gas line at the motor before
attempting any disassembly.
2. Do not disassemble the motor any further than necessary to
replace or repair damaged parts.
3. When grasping a pan in a vise, always use leather-covered or
copper-covered vise jaws to protect the surface of the part and
help prevent distortion. This is particularly true of threaded
members and housings.
4. Do not remove any part which is a press t in or on a
subassembly unless the removal of that part is necessary for
repairs or replacement.
5. If it necessary to disassemble a motor, always have new seals on
hand. Do not use old seals.
Assmbly
General Instructions
1. Always wipe all parts with a thin lm of oil before installing them
in the motor.
2. Always press on the inner ring of a ball-type bearing when
installing the bearing on a shaft.
3. Always press on the outer ring of a ball-type bearing when
pressing the bearing into a bearing recess.
4. Whenever grasping a part in a vise, always use leather-covered
or copper-covered vise jaws to protect the surface of the part
and help prevent distortion. This is particularly true of threaded
members and housings.
5. Lubricate the Rotor (3) and Vanes (4) with a good quality SAE 10
non-detergent oil. Lubricate the Bearings with Ingersoll-Rand No.
28 Grease. Coat the Rotor Shaft (6) with a good quality SAE 10
non-detergent oil.
6. If using gas to power the motor always test for leaks after
assembly. Refer to the Gas Operartion Test Procedure.

Trouble Shooting Guide
Trouble Probable Cause Solution
Low power or low free speed Low air pressure at the inlet Check air pressure at the inlet. For top
performance and durability of parts, the air
pressure must be 150 psig (10.3 bar /1030
kPa) at the inlet.
Worn or broken Vanes Install new set of Vanes
Improper lubrication or Dirt building up in
the Motor
Lubricate as instructed under LUBRICATION.
If this does not help, ush the Motor as
instructed under MAINTENANCE.
Rough operation Worn or broken Rotor Bearings Examine each Bearing. Install new bearing
where necessary.
Scoring of End Plates and/or Cylinder Rotor does not have proper clearance Motor must be refurbished.
