damage.
GENERAL SAFETY PRECAUTIONS ____________________
DANGER
INTAKE AIR. Can contain carbon monoxide or other
contaminants. Will cause serious injury or death.
Ingersoll-Rand air compressors are not designed,
intended or approved for breathing air. Compressed
air should not be used for breathing air applications
unless treated in accordance with all applicable
codes and regulations.
• WARNING
HAZARDOUS VOLTAGE. Can cause serious injury
or death. Disconnect power and bleed pressure
from the tank before servicing. Lockout/Tagout
machine. Compressor must be connected to
properly grounded circuit. See grounding
instructions in manual. Do not operate compressor
in wet conditions. Store indoors.
MOVING PARTS. Can cause serious injury. Do not
operate with guards removed. Machine may start
automatically. Disconnect power before servicing.
Lockout/Tagout machine.
HOT SURFACES. Can cause serious injury. Do not
touch. Allow to cool before servicing. Do not touch
hot compressor or tubing.
HIGH PRESSURE AIR. Bypassing, modifying or
removing safety/relief valves can cause serious
injury or death. Do not bypass, modify or remove
safety/relief valves. Do not direct air stream at body.
Rusted tanks can cause explosion and severe injury
or death. Drain tank daily or after each use. Drain
valve located at bottom of tank.
• CAUTION
RISK OF BURSTING. Use only suitable air handling
parts acceptable for pressure of not less than the
maximum allowable working pressure of the
machine.

Two-Stage Reciprocating Air Compressors
GENERAL INFORMATION
INTRODUCTION _____________________________________
This manual provides safe and reliable instructions for the
installation, operation and maintenance of your Ingersoll-Rand air
compressor. Carefully read this manual before attempting to
operate or perform any maintenance. If you are uncertain about any
of the instructions or procedures provided in this manual, contact
Ingersoll-Rand. We recommend you retain this manual, and all
publications provided with your air compressor, in a location which
is accessible to all personnel who operate and service your
compressed air equipment.
APPLICATION _______________________________________
Ingersoll-Rand's standard two-stage lubricated air compressors are
single-acting, air-cooled machines. Typical compressors are
furnished as compact, self-contained, air receiver tank mounted
units that are automatically regulated and driven by an electric
motor or gasoline engine. An air-cooled aftercooler, low oil level
shutdown switch and automatic drain valve are among the optional
accessories that can be furnished. Bare compressor pumps and
baseplate-mounted units are also available.
These compressors may be used for a variety of compressed air
application up to 250 PSIG (17.5 kg/cm²). Application of these
compressors as either a primary or supplementary source of air is
virtually unlimited in industrial plants, service stations and auto
repair shops. Supplementary service includes such uses as
furnishing air at pressure not carried in regular shop lines, air at
isolated locations, and standby service for air when larger
compressors are shut down.
TWO-STAGE OPERATION _____________________________
Two-stage compressors consist of one or two first-stage cylinders
with the same bore size and one second-stage cylinder with a
smaller bore size.
