EN-6 22204911 Rev. E
SELECTING A LOCATION
GENERAL
Select a clean, dry, well-lighted area with plenty of ventilation
proper cooling air ow and accessability. Locate the unit
atleast 12 inches (30 cm) from walls. Ensure that the unit is as
level as possible to avoid fuel spillage.
TEMPERATURE
Ideal operating temparatures are between
40 °F to 100 °F (4 °C to 37.8 °C). In lower temperatures, you
must protect safety/relief valves and drain valves from
freezing.
HUMID AREAS
In frequently humid areas, moisture may form in the bare
pump and produce sludge in the lubricant, causing running
parts to wear out prematurely. Excessive moisture is especially
likely to occur if the unit is located in an unheated area
that is subjected to large temperature changes. Two signs
of excessive humidity are external condensation on the
bare pump when it cools down and a“milky” appearance in
petroleum compressor lubricant. You may be able to prevent
moisture from forming in the bare pump by increasing
ventilation or operating for longer intervals.
NOISE CONSIDERATIONS
Consult local ocials for information regarding acceptable
noise levels in your area. To reduce excessive noise, use
vibration mounts or intake silencers, relocate the unit or
construct total enclosure or bae walls. Consult your dealer
for assistance.
INSTALLING THE ISOLATOR PADS
1. Install isolater pads (A) on all four feet with self-tap
screws (B).
2. Hand tighten screws.
INSTALLING THE INLET AIR FILTER
CAUTION
Do not operate without air inlet lter.
Install the air inlet lter at the inlet connection at the bare
pump. If heavy duty lteration is required, contact your dealer
for information.
INSTALLING DISCHARGE PIPING
If it is necessary to install air discharge piping or condensate
discharge piping, adhere to the following general guidelines.
Contact your dealer for more information.
WARNING
Do not use plastic pipe, rubber hose or lead-tin
soldered joints anywhere in the compressed air
system.
WARNING
If an after-cooler, check valve, block valve, or any
other restriction is added to the compressor discharge,
install a properly-sized ASME approved safety/relief
valve between the compressor discharge and the
restriction.
CAUTION
If you will be using Ingersoll Rand Synthetic

ENGINE LUBRICATION AND FUEL
CAUTION
Do not operate without lubricant or with inadequate
lubricant. Ingersoll Rand is not responsible for engine
failure caused by inadequate lubrication.
Refer to the engine operator’s manual provided with the unit
for engine lubrication and fuel requirements.
RELEASED 13/Feb/2019 14:38:46 GMT

EN-10 22204911 Rev. E
GENERAL
The air compressor is designed for 100% continious duty
operation with the use of Ingersoll Rand synthetic lubricant
and 60% continious duty operation with the use of petroleum
lubricant. In other words, synthetic lubricant allows the
compressor to pump continiously without cycling. Petroleum
lubricant limits the compressor to a maximum of 36 minutes
of pumping time per hour. The compressor should not cycle
more than 10 times per hour.
NORMAL START-UP
START-UP
1. Turn regulator adjusting knob counter-clockwise until
fully closed.
2. Attach hose and accessory.
3. This compressor package is equipped with a new
automatic unloader valve assy eliminating the need to
manually toggle the valve for engine starting.In addition,
the automatic unloader has a“Cold Start” feature shown
in the illustration below. This valve bleeds air from the
compressor discharge airstream during engine starting,
reducing engine starting torque requirements. These
valves are especially helpful on oil-lubed compressor
pumps that may be subject to low temperatures. When
the discharge line is at zero pressure, the Cold Start
valve is open. As the engine starts, air ows out of the
Cold Start bleed hole into the atmosphere; as discharge
pressure increases, the bleed hole closes and stays closed
until the end of the pump-up cycle. During normal
operation a negligible air ow may be felt at the Cold
Start bleed hole. This is not cause for concern.
COLD START
BLEED HOLE
4. Follow instructions in engine owner’s manual for starting
and running engine.
5. Using the tank pressure guage for referance, allow tank
pressure to build to maximum pressure.
CA
UTION
Unusual noise or vibration indicates a problem. Do not
continue to operate until you identify and correct the
source of the problem. IF EMERGENCY CONDITIONS
ARE ENCOUNTERED, SHUT-OFF THE MAIN POWER
IMMEDIATELY.
NOTICE
When the tank reaches cut-out pressure, the
compressor stops pumping but the engine continues
to run. When the reciever tank pressure drops below
the factory pre-set minimum, the compressor resumes
pumping and the tank builds to cut-out pressure.
6. Turn regulator adjusting knob clockwise to obtain
desired pressure, indicated by the guage mounted on
the regulator.
SHUT-DOWN
1. Follow instructions in engine owner’s manual for
shutting o engine.
2. Turn regulator adjusting knob counter-clockwise until
fully closed.
3. Remove accessory.
4. Turn regulator adjusting knob clockwise slowly to allow
air to escape from tank. When the tank pressure guage
indicates 20 psig, turn regulator adjusting knob counter-
clockwise until fully closed.
5. Open manual drain valve slowly to drain moisture from
tank and bleed remaining air.
6. Close manual drain valve.
7. Turn fuel shut-o valve to“o” position before
transporting unit.

BELT ADJUSTMENT
CHECKING BELT TENSION.
Check belt tension occasionally, especially if looseness is
suspected. New belts must also be properly tensioned upon
installation.
A quick check to determine if adjustment is proper may be
made by observing the slack side of the belt fora slight bow
when the unit is in operation. If a slight bow is evident, the
belt is usually adjusted satisfactorily.
TENSIONING BELTS.
Belt tensioning can be achieved by loosening the motor or
engine anchor screws, pushing the motor or engine away
from the pump, and retightening the motor or engine anchor
screws. Some units are equipped with a belt tensioning bolt
that, when turned, pulls the motor or engine away from the
pump. Otherwise, the motor can be easily moved by placing
a prying tool beneath it. A commercially available spreader or
other belt tensioning device can also be helpful.
Follow the procedures outlined below to correctly set and
measure belt tension.
1. Lay a straight edge across the top outer surface of the
belt drive from pulley to sheave.
2. At the center of the span, perpendicular to the belt,
apply pressure to the outer surface of the belt with a
tension gauge. Force the belt to the deection indicated
in the table below. Compare the reading on the tension
gauge to the table.
Model Deection
In Inches
Min. Tension
(Lbs.) (Used)
Max. Tension
(Lbs.) (New)
SS5 0.2 4.2 6.2
SS3 0.17 3.0 6.0
Ensure the pulley and sheave are properly aligned and the
motor anchor screws are adequately retightened prior to
restarting the compressor.
CAUTION
Improper pulley/sheave alignment and belt tension
can result in motor overload, excessive vibration, and
premature belt and/or bearing failure.
To prevent these problems from occurring, ensure
the pulley and sheave are aligned and belt tension is
satisfactory after installing new belts or tensioning

TANK INSPECTION
The life of an air receiver tank is dependent upon several
factors including, but not limited to, operating conditions,
ambient environments, and the level of maintenance. The
exact eect of these factors on tank life is dicult to predict;
therefore, Ingersoll Rand recommends that you schedule
a certied tank inspection within the rst ve years of
compressor service. To arrange a tank inspection, contact the
nearest IR Air Center or distributor, or call 1-800-AIR SERV.
If the tank has not been inspected within the rst 10 years
of compressor service, the receiver must be taken out of
service until it has passed inspection. Tanks that fail to meet
requirements must be replaced.
WARNING
Failure to replace a rusted air receiver tank could result
in air receiver tank rupture or explosion, which could
cause substantial property damage, severe personal
injury, or death. Never modify or repair tank. Obtain
replacement from service center.
