TYMCO MODEL DST-6 INTRODUCTION
The TYMCO MODEL DST-6 is a closed loop air sweeper, therefore it is important that all doors
and components attached to the hopper have rubber seals for proper sweeper operation. All
hopper doors must be completely closed for proper sweeper function. It is important that the op
-
erator become familiar with all seal areas used on the sweeper and keep them in good repair.
DST-6 SWEEPER OPERATION
WARNING! Operator must use all standard safety precautions and observe all
warning decals to avoid serious injury when working around the
sweeper.
All DST-6 Sweepers have an auxiliary electric hydraulic pump for running hydraulic compo
-
nents without having to start the auxiliary engine. A switch on the sweeper control panel
switches sweeper from engine to auxiliary hydraulic system. The auxiliary engine will not
start if this switch is not properly reset.
