Checklist Before Starting the Machine
□ Check the battery power. Charge batteries if power is
below 80%. Batteries take about 7.5 hours to charge.
□ Check the condition of the scrub brushes/scrub pads.
Replace brushes or pads if they are worn out. (Pads
may be flipped over and reused until both sides are
worn down).
□ Check the condition of the rear squeegee and reposition
or replace if it is worn. Always make sure squeegee is
clean before starting.
□ Check the condition of the skirt around the scrub deck.
Replace if it is worn or damaged.
□ Check that the recovery tank is empty and that floating
filter screen is clean.

Operating the machine
Warning:
Danger of fire or explosion. Do not use this
machine to pick up flammable or corrosive materials, or
reactive metals.
1. Overlap each scrub pass at least
3”
2. Keep the machine continuously moving. If you must
stop, turn off brushes, solution flow, and vacuum.
Otherwise scrubber may abrade the floor.
3. Squeegee assembly automatically raises when backing
up.
4. If squeegee leaves drag marks on the floor behind the
scrubber, wipe the squeegee to remove dirt. If squee-
gee still leaves drag marks, it may need to be replaced.
Check the condition of the squeegee. If the leading
edge is not square and meeting the ground firmly, it will
need to be repositioned or replaced.
