INTRODUCTION
To insure proper understanding of operation, cleaning and maintenance of your TYMCO
REGENERATIVEAIRSWEEPER,itisnecessarythatthisOperator’sManualandtheService
& Parts Manual be read and studied from cover to cover by the operator.Afull understanding
of this equipment will help the operator achieve the results expected of this machine.
Though, seemingly, a very simple machine, the TYMCO REGENERATIVE AIR SWEEPER
utilizes air instead of conventional rotary brushes, brooms and conveyers. Aerodynamic
problems that arise in the REGENERATIVE AIR SWEEPER are not as easily identified and,
therefore, necessitates a complete understanding of the machine.
The TYMCO REGENERATIVE AIR SWEEPER is designed to maintain cleaner surfaces at
higher speeds and at lower cost. The performance capability of this truly modern machine is
only limited by the initiative of those responsible for its operation. There are many different
conditions found in sweeping, and we believe it impossible to answer all of the problems
here. Most important in the operation and maintenance of this machine, is that it should be
KEPT CLEAN.
TheOperator’sManual includes the necessary checks, operating and adjustment procedures
neededbytheoperatorfromdaytoday.Foranyspecificadjustment,problem,ormaintenance
checks not explained in this manual, please refer to the Service & Parts Manual.
