Abstract
A bowling lane maintenance machine has its operating functions designed and controlled in such a manner that the machine may be battery-operated without loss of performance. Included in the operation are special movements of the machine at the pin deck to flick moisture off blades of the squeegee assembly and limited activation of the vacuum motor to reduce battery drain.
