GUIDE TO MAINTENANCE
For Service contact an authorized Ingersoll Rand distributor. All requests should include model
number and serial number. To obtain reliable and satisfactory service, this unit requires a
consistent preventive maintenance schedule. Maintenance schedule form is included to aid in
keeping the proper records.
Before performing any maintenance function, switch main disconnect switch to "off" position
to assure no power is entering unit. "Lock Out" or "Tag Out" all sources of power. Be sure all
air pressure in unit is relieved. Failure to do this may result in injury or equipment damage.

DAILY MAINTENANCE

1. Drain moisture from tank by opening tank drain cock located on bottom of tank. Do not open
drain valve if tank pressure exceeds 25 PSIG.
2. Turn off compressor at the end of each day's operation. Turn off power supply at wall switch.

WEEKLY MAINTENANCE

1. Clean dust and foreign matter from cylinder, cylinder head, motor, fan blade, air lines, and
tank.
2. Remove and clean intake air filters.
3. Check V-belts for tightness. The V-belts must be tight enough to transmit the necessary
power to the compressor. Adjust the V-belts as follows:
a. Remove bolts and cabinet to access compressor drive.
b. Loosen mounting hardware which secures motor to base. Slide motor within slots of
baseplate to desired position.
c. Apply pressure with finger to one belt at midpoint span. Tension is correct if top of belt
aligns with bottom of adjacent belt. Make further adjustments if necessary.
d. Check the alignment of pulleys. Adjust if necessary.
e. Tighten mounting hardware to secure motor on base.
f. Re-install cabinet and secure bolts.
Never operate unit without cabinet in place. Removal will expose rotating parts which can
cause injury or equipment damage.
EVERY 90 DAYS OR 500 HOURS MAINTENANCE
1. Check entire system for air leakage around fittings, connections, and gaskets using soap
solution and brush.
2. Tighten nuts and capscrews as required.
3. Check and clean compressor valves. Replace valves when worn or damaged.
Valves must be replaced in original positions. Valve gaskets should be replaced each time
valves are serviced.
4. Pull ring on pressure relief valves to assure proper operation.
