3. Look at the deflection over the full length of
the squeegee blade. The correct amount of
deflection for the rear squeegee blade is
15 to 20 mm (0.50 to 0.75 in). The front
slotted squeegee blade should contact the
floor with a slight deflection, 5 mm (0.13 to
0.25 in).
4. To adjust the amount of deflection, unlock
the height adjustment knobs on the two
squeegee casters by sliding the locking
bracket off to the side.
NOTE: If the locking brackets won’t slide over, lift
up the end of the squeegee to pick the caster up
off the floor slightly. Then slide the locking bracket
over.
5. Turn the adjustment knob clockwise to
decrease deflection, turn the adjustment
knob counter-clockwise to increase the
deflection. Be sure to turn the knobs the
same number of turns.
6. Start the engine and drive the machine
forward again to check the squeegee blade
deflection. Readjust the squeegee blade
deflection if necessary.
7. Slide the locking brackets back to lock the
height adjustment knobs.
8. Raise the squeegee when finished.
