PLACING MOTOR IN SERVICE
•Always install, operate, inspect and maintain this
product in accordance with all applicable standards
and regulations (local, state, country, federal, etc.).
•Always use clean, dry air at 90 psig (6.2 bar/620 kPa)
maximum air pressure at the inlet. Higher pressure
may result in hazardous situations including excessive
speed, rupture, or incorrect output torque or force.
•Be sure all hoses and fittings are the correct size
and are tightly secured. See Dwg. TPD905--2 for a
typical piping arrangement.
•Ensure an accessible emergency shut off valve has
been installed in the air supply line, and make others
aware of its location.
•Do not use damaged, frayed or deteriorated air hoses
and fittings.
•Keep clear of whipping air hoses. Shut off the
compressed air before approaching a whipping
hose.
•Always turn off the air supply and disconnect the air
supply hose before installing, removing or adjusting
any accessory on this motor, or before performing any
maintenance on this motor.
•Do not lubricate with flammable or volatile liquids
such as kerosene, diesel or jet fuel. Use only
recommended lubricants.
•Keep work area clean, uncluttered, ventilated and
illuminated.
•Do not remove any labels. Replace any damaged label.
USING THE MOTOR

PLACING MOTOR IN SERVICE
Lubrication
Ingersoll--Rand No. 50 Ingersoll--Rand No. 28
Always use an air line lubricator with this motor. We
recommend the following Filter--Regulator--Lubricator
Unit (FRL):
F o r U S A -- N o . C 2 2 -- 0 4 -- G 0 0
For International -- No. C26--C4--A29
After each forty hours of operation, or as experience
indicates, inject 1.5 cc of Ingersoll--Rand No. 28 Grease
into the Grease Fitting (55). Do not grease excessively.
Too much grease in the Gear Case will cause heating.
Grease leakage from the spindle end is also an indication
that an excessive amount of grease has accumulated
within the Gear Case.
Installation
Always use clean dry air at 90 psig (6.2 bar/620 kPa)
maximum air pressure. Dust, corrosive fumes and/or
excessive moisture can ruin the motor of an air tool. An
air line filter can greatly increase the life of an air tool.
The filter removes the dust and moisture. Be sure all hoses
and fittings are the correct size and tightly secured. See
Drawing TPD905--2 for a typical piping arrangement.

It is important that the motor be serviced and inspected at
regular intervals to maintain safe, trouble--free operation
of the motor.
Tools, hose and fittings shall be replaced if unsuitable for
safe operation and responsibility should be assigned to
ensure that all tools requiring guards or other safety
devices are kept in operating condition. Maintenance and
repair records should be maintained on all tools.
Frequency of repair and the nature of the repairs can
reveal improper application or use. Scheduled
maintenance by competent authorized personnel should
detect any mistreatment or abuse of the motor and worn
parts. Corrective action should be taken before returning
the motor for use.
When replacement parts are necessary, consult
Maintenance Section for part identification.
Maintenance Instructions
When removing a Spindle Planet Gear Shaft (61) from the
Spindle (59), always press it out so that it is ejected at the
short hub end of these parts. Likewise, when installing a
Shaft, start it into the narrow flange at the short hub end.
This is important, as the shaft holes are slightly tapered, so
the Shaft fits much tighter in the front, or wide, flange of
the Spindle.
Spindle Planet Gear Bearings (63) must be installed with
care to avoid distorting or fracturing the thin shell
surrounding the needles. Use a bearing inserting tool, as
shown in Drawing TPD786, when installing a needle
bearing. Press only on the stamped end of the bearing.
Press one bearing from each end of the hole when two
bearings are used in one gear. Never use one bearing as an
anchor for installing the second bearing.
