HOWTHEMACHINEWORKS
The scrub componentsof the machine are a
solution tank,scrub brushes,asqueegee,a
vacuumfan,and a recoverytank.
Waterand detergent, fromthe solution tank, flow
tothe floorthrough a solution valvetothe scrub
brushes.The brushes scrub the floor.Asthe
machine ismoved forwardthe squeegee wipes
the dirty solution off the floor,whichisthen picked
up and drawnintothe recoverytank.
The steering handles controlthe direction and
speed of the machine inforward or reverse.By
rotating the steering handlesforward, the machine
propelsforward.Byrotating the handlestowards
you the machine propelsbackward.
When using the EStmode, the dirty solution in
the recoverytankisfiltered and returned tothe
solution tanktobereused.
Three differentwidthsofscrub headsand
squeegeesare availableforthe machine,along
withtwo differentbrushtypes.
The scrub head widthsare asfollows; the model
700 (700 mm (28 in)), the model800 (800 mm
(32 in)),and the model900 (900 mm (36 in)).The
700 mm (28 in)squeegee isused withthe 700
modelscrub head,aswell asthe 800 mm (32 in)
withthe model800,and the 900 mm (36 in)with
the model900.The two available brushtypesare
disk and cylindrical.
