INTAKE FILTER CLEANING _________________________
Remove the intake filter every 50 hours or once a week and

compressed air. Turn the wing nut counterclockwise to
disassemble intake filter.
•

liquid or solvent.
•

NOTE
Replace the filter element when it becomes
dirty.
TANK DRAINING __________________________________
Drain both tanks daily or after 4 hours of use. Open drain cock
and tilt compressor to empty accumulated water.
COMPRESSOR PUMP OIL CHANGE _________________
•
CAUTION
Do not operate without lubricant or with
inadequate lubricant. Ingersoll Rand is not
responsible for compressor failure caused by
inadequate lubrication.
•
CAUTION
Overfilling with oil will cause premature
compressor failure. Do not overfill.
1.
Within the first 50 hours of operation, completely replace the oil of
the pumping element. Unfasten the oil drain cap on the casing
cover, drain all the oil, and screw the cap back on.
2.
Pour All-Season Select or other approved oil into the hole of the
dipstick to the level indicated on the dipstick. See “Preparation for
Use” section for lubricant recommendations.
3.
Check the oil level of the pumping element every 50 hours or
once a week.
4.
Change the oil according to the following intervals:
Mineral oil = 100 hours or every 6 months.
All Season Select = 300 hours or every 12 months.
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 effect of
these factors on tank life is difficult to predict; therefore, Ingersoll
Rand recommends that you schedule a certified tank inspection
within the first five years of compressor service. To arrange a
tank inspection, contact the nearest Ingersoll Rand Customer
Center or distributor, or call 1-800-AIR SERV.
If the tank has not been inspected within the first 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.
