Scrub System, Cylindrical108Service Manual
SC6500|7. If the belt is not seatedproperly in the pulley grooves,gently push or pull in thedirection that the belt mustmove while rotating the belt.8. Reinstall the Belt Guard andSide Skirt Assembly, then testthe scrub system for correctoperation.Lift Actuator AdjustmentThe lift actuator adjustment makes sure that the deck can be properly positioned when extended forscrubbing operations and when retracted for machine transport. The adjustment sets the position of thedrive nut on the actuator lead screw when either of the internal travel limit switches open in order to stopthe motor rotation. The retracted position is set by running the motor in the retracted position until themotor stops and then screwing the drive nut onto the lead screw until it is in the correct location. Once theretracted position is established, the extended position is set by adjusting an internal cam under the rubbercover of the actuator motor .Using the Actuator Power Cord AdapterThe adjacent drawing shows the specialactuator power cord adapter (p/n 56407502)that is needed to connect the machine’sbattery pack and actuator motor for settingthe actuator drive nut limit settings. Toconnect the actuator power cord adapter:1. Open the machine battery compartmentand disconnect the battery connector. Thebattery pack is needed to power the scrubdeck actuator motor to correctly set the INand OUT limit switches.2. Connect the actuator motor to be tested tothe power cord adapter end.3. Connect the alligator clips from the cord adapter (red clip to the positive and black to negative) tobattery connector or battery posts. Use the rocker switch on the actuator power cord adapter to changethe motor rotation when setting the correct actuator drive nut dimensions.Service Note: You can also use the above actuator power cord adapter to help position the drivenut/spring housing assembly (in or out) for ease in actuator motor installations.Belt NotSeatedBelt Seated
