Note: Motor should operate at between 11,000 and 12,000 RPM at 6.2 bar (90 PSIG). RPM should be checked with a tachometer. Before operating,
we recommend that 2-3 drops of Dynabrade Air Lube P/N 95842 (or equivalent) be placed directly into the air inlet with throttle lever depressed. Operate the
machine for approximately 30 seconds before application to workpiece to determine if machine is working properly and safely and to allow lubricating
oils to properly dispense through machine.
