Chapter 10: Maintenance
NOTE:
Make sure that the pin is short enough so that you can pull it out
after the assembly is in place.
2. Connect the motor cable to the new drive assembly.
3. Install the new drive assembly over the three studs at the top of its bracket.
Use the nuts, screws, and washers you removed from the old drive assembly.
4. Remove the pin or screw you used to hold the wheel in the up position.
5. Put the side cover next to the platform, and attach the cable to the light disc PCA.
6. Reinstall the side cover.
7. Connect the battery power and data cables, and close the battery compartment door.
8. Reinstall the rear cover.
Platform Casters
The platform casters should be checked every 3 months. If they show signs of cracking, excess-
ive wear, or any damage they should be replaced.
All four platform casters are identical, and are mounted to the platform in the same way.
NOTE:
If you have a means of lifting the chassis of the platform enough to
access the screw that holds on the caster, you can avoid removing the battery,
which is only necessary to tilt the platform on its side.
If you cannot lift the chassis enough to access the caster screw:
1. Move the payload structure out of the way.
If the payload structure can be completely removed, do so. This enables you to tip the
AMR on its side, so you have access to the casters underneath.
2. Remove the inner rear cover.
3. Unlatch and open the battery compartment door, at the back of the platform.
The battery compartment door is capable of being locked. You may need to unlock it
before opening.
4. Disconnect the battery by unplugging the two cables at the rear of the battery.
5. Remove the battery from the platform.
6. Remove the side covers.
7. Lay the body of the platform on its side, exposing the casters.

WARNING:
MAGNETIC FIELD - MEDICAL IMPLANT RISK
Magnetic fields can be hazardous to medical implant wearers. Medical
implant wearers stay back 30 cm (12 inches) from the underside of the
platform, which is exposed during this maintenance procedure when
the platform is tipped on its side.
Whether or not you had to remove the battery:
