SCRUB DECK REMOVAL
1 See Figure 2. Pull off the two vacuum recovery Hoses (A) from the Vacuum Shoes (B) .
2 Remove both vacuum pickup shoes by removing the two black Knobs (C) then lift up and pull out the retainer Bars (D) to separate them from
the scrub deck pins. Next pull back the pickup shoe from the deck bearing mounts to complete their removal.
3 Remove the sweep debris Hopper (E) from the scrub deck.
4 Lower the scrub deck with the brush(s) installed. Attention: Don’t turn the key switch off until after disconnecting the battery pack by pushing
in (activating) the Battery Disconnect (13) . This procedure is done to prevent the scrub deck from automatically raising when the key is turned
off.
5 Remove the wing Nut (F) that secures the solution nozzle tree Assembly (G) to the scrub deck then pull the assembly with hoses to the side.
6 Unplug the brush motor wiring Harness (H) (under left side of machine).
7 Remove the lower hitch Pin (I) that secures the brush deck lift actuator to the scrub deck.
8 Remove the two Hitch Pins (J) that attach the scrub deck to the machine chassis linkage arm weldment.
9 From the right side of the machine swing the brush deck actuator housing forward to clear the deck mount bracket. Then carefully maneuver
the deck out from under the machine to complete its removal. Service Note: It is important that the disconnected deck actuator motor is not
run. This precaution will prevent the actuator drive nut from being moved from its set speci
fi cation.
10 To install the scrub deck follow the above steps in reverse order.
