MAINTENANCE
ADJUSTING THE REAR SQUEEGEE BLADE
DEFLECTION
Def l ection is the amount of curl the overall
squeegee blade has when the machine moves
forward. The best def l ection is when the
squeegee wipes the f l oor dry with a minimal
amount of def l ection.
NOTE: Make sure the squeegee is level before
adjusting the def ection. 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 def l ection or “curl” of
the squeegee blade. The correct amount of
def l ection is 12 mm (0.50 in) for scrubbing
smooth f l oors and 15 mm (0.62 in) for rough
f l oors.
3. Lower the rear bumper door / step .
4. To adjust the overall squeegee blade
def l ection, loosen the lock knobs on both sides
of the machine.
5. Turn the adjustment knobs clockwise to
increase def l ection or counterclockwise to
decrease def l ection.
6. Retighten the lock knobs.
7. Drive the machine forward again to recheck
the squeegee blade def l ection.
8. Readjust the squeegee blade def l ection if
necessary.
9. Raise the rear bumper door / step when
f i nished adjusting the rear squeegee blade
def l ection.
