ADJUSTING REAR SQUEEGEE BLADE
DEFLECTION
Deflection is the amount of curl the squeegee
blade has when the machine moves forward with
the squeegee lowered to the floor. The best
deflection is when the squeegee wipes the floor
just dry with a minimum amount of deflection.
1. Turn the machine power on.
2. Lower the squeegee.
3. Set the machine parking brake while driving
the machine slowly forward, and turn the
machine power off.
FOR SAFETY: Before leaving or
servicing machine; stop on level
surface, set parking brake, turn off
machine and remove key.
4. Look at the deflection of the squeegee
blade. The correct amount of deflection is
15 to 20 mm (0.50 to 0.75 in).
5. To adjust the amount of deflection, loosen
the caster jam nut. Turn the caster shaft
using the flats.
Turn the shaft clockwise to decrease the
blade deflection. Turn the shaft
counter-clockwise to increase blade
deflection. Tighten the jam nut.
6. Release the parking brake and drive the
machine forward again to check the
squeegee blade deflection.
7. Readjust the squeegee blade deflection if
necessary.
