Alternate Lubricants
You may use a petroleum-based lubricant that is premium quality, does not
contain detergents, contains only anti-rust, anti-oxidation, and anti-foam agents
as additives, has a flashpoint of 440°F (227°C) or higher, and has an auto-ignition
point of 650°F (343°C) or higher.
See the petroleum lubricant viscosity table below. The table is intended as a
general guide only. Heavy duty operating conditions require heavier viscosities.
Refer specific operating conditions to your dealer for recommendations.
Temperature Around Unit Viscosity @ 100°F (37.8°C) Viscosity Grade
°F °C SUS Centistokes ISO SAE

below 4.4 & below 150 32 32 10
40 - 80 4.4 - 26.7 500 110 100 30
80 - 125 26.7 - 51.0 750 165 150 40
If you use a petroleum-based compressor lubricant at start-up and decide to
convert to
Ingersoll Rand synthetic compressor lubricant later on, the
compressor valves must be thoroughly decarbonized and the crankcase must be
flushed before conversion.
Filling Procedures
1. Unscrew and remove the oil fill plug (A).
2. Slowly fill the crankcase with lubricant until the lubricant reaches the top thread
of the oil fill opening and the top of the sight glass (B). Crankcase capacity is
one-half (0.5) liter.
3. Replace the oil fill plug HAND TIGHT ONLY.
OPERATION
General
Your air compressor was designed for 100% continuous duty operation with the
use of
Ingersoll Rand synthetic compressor lubricant and 60% continuous duty
operation with the use of petroleum lubricant. In other words, synthetic lubricant
allows the compressor to pump continuously 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.
Initial Start-Up
Follow this procedure before putting the unit into service for the first time:
1. Set the pressure switch lever (A) to “OFF”.
2. Open the service valve fully to prevent air pressure from building in the tank.
(A=Open, B=Closed).
3. Move the pressure switch lever to “ON/AUTO”. The unit will start.
4. Run the unit for 30 minutes. Ensure the service valve is fully open and there is no
tank pressure build up.
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.
5. After 30 minutes, close the service valve fully. The air receiver will fill to cut-out
pressure and the motor will stop. The unit is now ready for use.
Normal Start-Up
1. Set the pressure switch lever to “OFF”.
2. Close the service valve.
3. Attach hose and accessory.
4. Move the pressure switch lever to “ON/AUTO”. The unit will start.
5. Allow tank pressure to build. The motor will stop when tank pressure reaches
cut-out pressure.
6. Open the service valve. The unit is now ready for use.
When the receiver tank pressure drops below the factory pre-set
minimum, the pressure switch resets and restarts the unit.
When You Are Finished
1. Set the pressure switch lever to “OFF”.
2. Close the service valve fully.
3. Remove the air tool or accessory.
4. Slowly open the service valve to bleed air pressure down to 20 psig.
5. Slowly open the manual drain valve at the bottom of the tank to drain all
condensate (water).
6. Close the drain valve and the service valve for the next use.

WARNING
NOTICE
Pressure Switch :
The Pressure Switch is Pre-set at the required pressure. The range and differential
settings ARE NOT adjustable. The Pressure Switch should not be tampered with in
any way and no attempt should be made to adjust the pressure settings as this
could damage the Switch to the point of failure and/or void any warranty for the
Pressure Switch.
