DEBRIS HOPPER
The debris hopper collects debris picked up by the
scrub brushes. It is located behind the scrub
brushes.
A vacuumized debris screen is located on the
bottom of the debris hopper to draw water solution
out of the debris collected in the hopper.
The debris hopper should be emptied whenever the
recovery tank is drained. It should be sprayed clean
daily.
To empty the debris hopper, raise the scrub
attachment with the hopper lift and side brush lever.
The debris will empty as the unit is lifted and tilted
back.
