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 16575540 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
4. Emergency shut-off valve
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.
The original language of this manual is English.
Tool repair and maintenance should only be carried out by an authorized Service Center.
