RECOVERY TANK
The recovery tank stores the water solution
picked up by the machine squeegee and vacuum
fan. The recovery tank is located at the rear of the
machine.
The recovery tank should be drained after the
solution tank is empty or whenever the float rises
and stops the water vacuum.
Clean the recovery tank after every work shift. An
inspection door has been provided to make the
tank cleaning job easier. It is located on the top of
the recovery tank.
Keep vacuum hoses clean. Clogged hoses are a
common cause of poor water pickup.

parking brake.
