Sound and vibration values were measured in compliance with internationally recognized
test standards. The exposure to the user in a specific tool application may vary from these
results. Therefore, on site measurements should be used to determine the hazard level in
that specific application.
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 47132782 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:
