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 04581666 and table on page 2.
