ADJUSTING THE REAR SQUEEGEE BLADE
DEFLECTION
Deflection is the amount of curl the overall
squeegee blade has when the machine moves
forward. The best deflection is when the
squeegee wipes the floor dry with a minimal
amount of deflection.
NOTE: Make sure the squeegee is level before
adjusting the deflection. See LEVELING THE
REAR SQUEEGEE.
1. Lower the squeegee and drive the machine
several meters (feet) forward and slowly bring
the machine to a stop.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, set parking brake, and remove key.
2. Look at the amount of deflection or “curl” of
the squeegee blade. The correct amount of
deflection is 12 mm (0.50 in) for scrubbing
smooth floors and 15 mm (0.62 in) for rough
floors.
3. Lower the Rear bumper door / step.
4. To adjust the overall squeegee blade
deflection, loosen the lock knobs on both
sides of the machine.
5. Turn the adjustment knobs clockwise to
increase deflection or counterclockwise to
decrease deflection.
6. Retighten the lock knobs.
7. Drive the machine forward again to recheck
the squeegee blade deflection.
8. Readjust the squeegee blade deflection if
necessary.
9. Raise the Rear bumper door / step when
finished adjusting the rear squeegee blade
deflection.
