Abstract
The head assembly of a floor burnisher is suspended by a main lift assembly and a fine adjustment assembly. The main lift moves the head assembly between a raised position in which the pad assembly is raised and tilted for access, and a lowered position in which the pad driver is suspended slightly above the floor, ready for use. The fine adjustment assembly permits the operator to control very accurately and conveniently the final operating pressure of the pad when the burnisher is turned on.
