Installation and Lubrication
Size air supply line to ensure tool’s maximum operating pressure (PMAX) at tool inlet. Drain
condensate from valve(s) at low point(s) of piping, air filter and compressor tank daily. Install
a properly sized Safety Air Fuse upstream of hose and use an anti-whip device across any
hose coupling without internal shut-off, to prevent hose whipping if a hose fails or coupling
disconnects. See drawing 47151048 and table on page 2. Maintenance frequency is shown in a
circular arrow and defined as h=hours, d=days, and m=months of actual use. Items identified as:
1. Air filter
2. Regulator
3. Lubricator
5. Hose diameter
6. Thread size
7. Coupling
9. Oil
10. Grease
4. Emergency shut-off valve
8. Safety Air Fuse
Parts and Maintenance
When the life of the tool has expired, it is recommended that the tool be disassembled,
degreased and parts be separated by material so that they can be recycled.
Tool repair and maintenance should only be carried out by an authorized Service Center.
Refer all communications to the nearest Ingersoll Rand Office or Distributor.
