FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
WARNING
Always wear eye protection
when operating or perform-
ing maintenance on this
pump.
WARNING
Do not use damaged, frayed
or deteriorated air hoses
and fittings.
LUBRICATION
Ingersoll–Rand No. 50
Always use an air line lubricator with this pump.
We recommend the following Filter–Lubricator–Regulator
Unit:
For USA – No. 8LUB12
For International – No. 8LUB12
Before starting the pump, fill the oil chamber in the
Backhead (1) with Ingersoll–Rand No. 50 Oil and inject
about 3 cc of oil into the air inlet before attaching the air
hose.
Before starting the pump and after four hours of
operation, unless the air line lubricator is used, detach the
air hose and fill the oil chamber in the Backhead (1) with
Ingersoll–Rand No. 50 Oil.
After each forty hours of operation, or as experience
indicates, inject 5 – 10 cc of the Ingersoll–Rand No. 80
Grease into the Grease Fitting (15).
Never use ordinary cup grease as it emulsifies with water
and will not lubricate in this condition. Automotive water
pump grease is not satisfactory as it is made for use with
hot water.
AIR STRAINER
Periodically, clean the Air Strainer Screen (9) as follows:
1.
Shut off the air supply to the pump.
2.
Unscrew the Air Strainer Plug (11).
3.
If the Screen still appears clogged, unscrew the Air
Strainer Cap (10) and withdraw the Screen. Clean the
Screen in a suitable cleaning solution.
WARNING LABEL IDENTIFICATION
90 psig
(6.2 bar/620 kPa)
PLACING PUMP IN SERVICE
Ingersoll–Rand No. 80
WARNING
Always wear hearing
protection when operating
this pump.
WARNING
Operate at 90 psig (6.2 bar/
620 kPa) Maximum air pressure.
IMPELLER ADJUSTMENT
For the most efficient operation of the pump, particularly
against high heads, it is necessary that the clearance
between the Impeller (42) and the Impeller Cover (46) be
limited. This clearance is set at 0.010" at the factory.
When, due to wear, this clearance has increased to about
1/32", an adjustment can be made by removing enough of
the Impeller Cover Shims (45) to obtain the original 0.010"
clearance. This simple adjustment will prolong the life of
the Impeller and maintain the high efficiency of the pump.
The Impeller Cover Shims are different colors to identify
the various thicknesses.
White is 0.025" Brown is 0.010"
Pink is 0.015" Blue is 0.005"
Impeller Shims (41) are used as required between the
Impeller and the Impeller Spacer (40) to provide running
clearance between the Impeller and the Housing (14).
When assembling a pump, install only enough Impeller
Shims to permit the Impeller to rotate without any drag.
OILER ADJUSTMENT
The Oiler is adjusted at the factory, but since flow rate
varies somewhat with temperature, readjustment may be
necessary. The rate of flow is regulated by an Oiler
Adjusting Screw.
To regulate the Oiler:
Remove the Backhead and turn the Oiler Adjusting Screw.
Turning the Screw clockwise decreases the flow; turning
the Screw counterclockwise increases the flow. Under no
circumstances should the Screw be backed out beyond the
face of the Backhead.

WARNING
Always turn off the air sup-
ply and disconnect the air
supply hose before install-
ing, removing or adjusting
any accessory on this pump,
or before performing any
maintenance on this pump.
