SCRUB BRUSH SYSTEM
SCRUB BRUSH DECK REMOVAL (DISC & CYLINDRICAL)
1 Remove both deck side skirt assemblies. NOTE: This step is optional, you may fi nd deck removal easier with the skirts removed.
2 Lower the scrub deck with brushes (pads) installed. ATTENTION: Don’t turn the key switch off until after disconnecting the battery pack by
pushing in (activating) the Emergency Disconnect (13). This procedure is done to prevent the scrub deck from automatically raising when the
key is turned off.
3 See Figure 2. Separate the solution system water line (quick disconnect fi ttings), located on top of the scrub deck. Grip the bottom movable
Sleeve (A) on the quick disconnect fi tting assembly and pull on the top Fitting (B) to separate the hoses.
4 Unplug the brush motor wiring harness (C) (under left side of machine).
5 Remove the lower Hitch Pin (D) that secures the brush deck lift actuator to the scrub deck.
6 Remove the two (E) Hitch Pins that attach the scrub deck to the machine chassis linkage arm weldment.
7 From the right side of the machine swing the lower actuator housing forward to clear the deck mount bracket. Then pull the deck out from under
the machine to complete the removal. Service Note: It is important that the actuator motor is not run while it is disconnected from the deck or
chassis mounts. This precaution will prevent the actuator drive nut from being misadjusted (moved out of its set specifi cation).
8 To install a scrub deck follow the above steps in reverse order.
