MAINTENANCE
AIR FILTER ELEMENT CHANGE PROCEDURE
1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Unscrew the retaining cap and withdraw the old element.
3. Fit the new element.
4. Replace the retaining cap.
SEPARATOR ELEMENT CHANGE PROCEDURE
1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Loosen separator element with the correct tool.
3. Remove the element from the housing; place it in a sealed bag
and dispose of it safely.
4. Clean the mating face of the housing.
5. Remove the new Ingersoll–Rand replacement element from its
protective package.
6. Apply a small amount of lubricant to the element seal.
7. Screw the new element down until the seal makes contact with
the housing, then hand tighten a further half turn.
8. Start the compressor and check for leaks.
CAUTION
This unit is not designed or intended to operate when
contaminated with silicone. Lubricants, greases or other items
containing silicone should not be used on this unit.

COOLER CLEANING PROCEDURE
1. Stop the machine, electrically isolate and vent all trapped pressure.
2. Remove the top cover to obtain access to the cooler.
3. Clean the cooler.
4. Rebuild in reverse order.
BELT CHECKING AND ADJUSTMENT PROCEDURE
Check belt tension occasionally, especially if looseness is
suspected. A quick check to determine if adjustment is proper may be
made by observing the slack side of the belt for a slight bow when the
unit is in operation. If a slight bow is evident, the belt is usually adjusted
satisfactorily.
A belt tension measurement device can be used to determine the
tension of the belt.
Belt tensioning can be achieved by loosening the airend anchor
screws, a belt tensioning bolt is provided to aid in moving the airend.
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 deflection indicated in the table below, and compare the reading on
the tension gauge to the figures shown.
