Chapter 8: Maintenance
Docking Station Roller and Bearing
The roller, which guides the AMR onto the docking station, can become worn after extended
use. The time to replace the roller should be based on your visual inspection and judgment of
when it is too worn. We do not specify a quantitative measure for this.
Refer to the following figure for the location of the roller.
WARNING: ELECTROCUTIONRISK
Unplug power from the docking station before starting. Remove the power cord
at the docking station.
A shoulder bolt holds the roller to the docking station.
1.
Remove the shoulder bolt from the center of the roller. Retain the shoulder bolt.
2.
Remove the roller and bearing from the docking station.
3.
Install the new roller and bearing, using the retained shoulder bolt.

Docking Station ACPower Fuse
NOTE: The current version of the docking station uses a thermal fuse, built into
the power switch. There are no user-serviceable fuses.
NOTE: The following procedure applies only to legacy docking stations.
The only user-serviceable fuses are in the docking station. The two external AC fuses are loc-
ated between the power switch and the ACpower plug.
