GRS GraverMax Rotary Valve Cleaning

This video demonstrates how to perform a rotary valve cleaning on the GRS GraverMax.
Perform this cleaning if your handpiece is receiving a steady stream of air from the machine instead of consistent pulses of air.
Apply a small amount of denatured or isopropyl alcohol to your paper towel when cleaning rotary valve and rotor.
