Leveling The Rear Squeegee; Adjusting Rear Squeegee Blade Defl Ection - Tennant T7AMR Operator's Manual

LEVELING THE REAR SQUEEGEE

Leveling of the squeegee assures the entire length
of the squeegee is in even contact with the surface
being scrubbed. Perform this adjustment on an
even and level fl oor.
1. Lower the squeegee and drive the machine
forward a few feet.
2. Turn off the machine ON/OFF key switch.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
3. Look at the defl ection of the squeegee over the
full length of the squeegee blade.
4. If the defl ection is not the same over the full
length of the blade, turn the squeegee leveling
bolt to make adjustments.
The squeegee leveling bolt is located directly
behind the squeegee suction hose. DO
NOT disconnect the suction hose from the
squeegee frame when leveling squeegee.
Turn the squeegee leveling bolt counter-
clockwise to increase the defl ection at the
ends of the squeegee.
Turn the squeegee leveling bolt clockwise
to decrease the defl ection at the ends of the
squeegee blade.
5. Drive the machine forward with the squeegee
down to recheck the squeegee blade defl ection
if adjustments were made.
6. Readjust the squeegee blade defl ection if
necessary.

ADJUSTING REAR SQUEEGEE BLADE
DEFLECTION
Defl ection is the amount of curl the overall
squeegee blade has when the machine moves
forward. The best defl ection is when the squeegee
wipes the fl oor dry with a minimal amount of
defl ection.
1. Lower the squeegee and drive the machine
forward a few meters (feet).
2. Turn off the machine ON/OFF key switch.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
3. Look at the amount of defl ection or "curl" of
the squeegee blade. The correct amount of
defl ection is 12 mm (0.50 in) for scrubbing
smooth fl oors and 15 mm (0.62 in) for rough
fl oors.
4. If the overall squeegee blade defl ection needs
to be adjusted, loosen the jam nuts on the
squeegee casters and adjust the height.
5. Drive the machine forward again to recheck
the squeegee blade defl ection after
adjustments are made.
6. Readjust the squeegee blade defl ection if
necessary.
