OPERATION
275 SERIES II MM190 (12---89)
2-18
TO SCRUB
Plan the scrubbing in advance. Try to arrange long
runs with minimum stopping and starting. Do an
entire floor or section at one time.
Pick up oversize debris before scrubbing. Remove
bulky debris from aisles before scrubbing. Pick up
pieces of wire, twine, string, etc., which could
become entangled in brush or brush plugs.
Allow a few inches overlap of brush paths.
Do not turn steering wheel too sharply when the
machine is in motion. It is very responsive to the
movement of the steering wheel. Avoid sudden
turns, except in emergencies.
Try to scrub as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine.
Floor conditions, amount of soilage, type of soilage,
brush action, and squeegee action all play an
important role in determining the type and
concentration of detergent to be used. For specific
recommendations, consult the local Tennant
Company Representative.
WARNING: Flammable materials can
cause an explosion or fire. Do not use
flammable materials in solution tank.
The recovery tank should be drained after the
solution tank is empty and whenever the ball float
rises and stops water vacuum. The recovery tank
may fill before the solution tank empties if standing
water is picked up in addition to the solution put
down by the machine.
For best scrubbing results, reduce speed to one-half
maximum machine speed. Shut off solution flow to
floor 5 ft (1525 mm) before making turns. Adjust
solution flow to floor with solution flow knob to match
floor conditions.
Always raise the rear squeegee before backing
machine.
1. Stop the engine and set the machine parking
brake before filling solution tanks.
FOR SAFETY: Before leaving or servicing the
machine; stop on level surface, set parking brake,
and turn off machine.

solution tanks. Fill the tanks with water.
