Scrub Brush Deck
Warning! Engage the parking brake and chock both rear wheels so the machine can’t roll.
1. Loosen the four side
skirt Retainer Knobs
(two per side) and
remove the Side Skirt
Assemblies
from the
deck.
2. Slide out the Hopper.
3. With the scrub
brushes installed in
the deck, press the
Scrub On button to
lower the deck to the
oor.
Service Note: Once the brush deck is in the lowered position, don’t turn the key switch off until
you disconnect the battery pack (push in the Emergency Disconnect). This will
prevent the scrub deck from automatically rising when the key is turned off.
4. Turn the key switch off.
5. Remove the Solution Feed Hose at the solution solenoid valve located underneath the left side of the
machine ahead of the rear wheel.
6. Remove bottom lift actuator Cotter Hair Pin, then push the Retainer Pin from its housing and mount
bracket holes.
7. Disconnect the actuator wire harness connector. Note that this will prevent the actuator from being
switched on and rising when it is disconnected from its deck mount.
Service Note: Connect the Advance power cord adapter (p/n 56407502) to the lift motor harness,
then position (relieve the pressure on) the Retainer Pin for ease of removal.
8. Note the correct brush motor wire connections at each individual motor, then remove all the wiring from
the motor terminals.
9. Locate the ID (identication) Resistor Plug on the scrub brush deck and separate its connector.
10. Remove the four Hex Nuts, hex screws and bushings from the left and right front deck supports, then
swing the Pivot Support Arms away from their mounting holes.
