FORM NO. 56043122 - BR 1100S, 1300S - 25SCRUB BRUSH SYSTEM - 2SCRUB BRUSH DECK ASSEMBLY REMOVAL (CYLINDRICAL)WARNING!1 Set machine parking brake (6) and block (choke) both rear wheels so machine can’t roll.2 See Figure 2.6. Loosen the (4) side skirt Retainer Knobs (A) (2 per side) and pull the Skirt Assemblies (B) off from the deck. Next remove, slide out the reardeck debris tray.3 With the scrub brushes on the machine lower the scrub deck to the floor by pressing the “Scrub ON” button. Special Service Note: After brush deck is in thelowered position don’t turn the key switch off until disconnecting the battery pack (push in the Emergency Disconnect (11)). This procedure is done to preventthe scrub deck from automatically raising when the key is turned off.4 Turn the master key to the OFF position.5 Remove the solution feed Hose (C) at the solution solenoid valve located underneath the left side of the machine ahead of the rear wheel.6 Remove bottom lift actuator Hair Pin (D), then push the Retainer Pin (E) from its housing and mount bracket holes. Next disconnect the actuator wire harnessconnector. Note: This will prevent the actuator from being turned on and rising when it is disconnected from its deck mount. Service Tip: Connect the Advancepower cord adapter (P.N. 56407502) to the lift motor harness then position (relieve the pressure on) the Lift Pin (E) for ease of removal.7 Reference the correct brush motor wire connections at each individual motor then remove all the wiring from the motor terminals. Next locate on the brushdeck the motor deck ID (identifi cation) Resistor Plug (F) and separate its connector.8 From the left and right front deck supports remove the (G) (4) hex nuts, hex screws and bushings then swing the Pivot Support Arms (H) away from theirmounting holes. Special Service Note: The removal of both the left and right side brooms and both the front chassis corner rollers will allow easier access tothe (4) front scrub deck support arms’ mounting hardware.WARNING!9 Safely jack up the front of the machine 1-1/2 – 2 inches (38-50 mm) and put a wood block (2 x 4) underneath the drive wheel for a safety support.10 The deck Actuator (J) must be put into its retracted (up) position to allow needed clearance when pulling the deck assembly out from underneath the machine.Service Tip: Connect the power cord adapter (P.N. 56407502) to the motor; hold the actuator housing and run (shorten) the actuator housing length. See theActuator Drive Nut Adjustment section in this manual for additional operational details. An alternate method to gain the needed actuator clearance to slide thedeck out from under the machine would be to safely jack up the front of the machine.Warning! Support both front corners with proper jack stands or blocking before working underneath the machine.11 Carefully slide the complete deck assembly out from underneath the machine from either side. Note: Observe the position of the disconnected lift actuatorhousing and swing it to the rear to clear its mount bracket pocket.FIGURE 2.6
