Chapter 10: Maintenance
Cleaning Casters on ESD Platforms
Casters on the ESD platform are critical components as they provide the path to ground. As
such, they require regular, periodic cleaning to preserve ESD protection capability.
!
CAUTION:
PERSONAL INJURY OR PROPERTY DAMAGE RISK
This procedure requires placing the platform on its side. Unless you can do
this safely with the payload attached, you will need to remove the payload.
You will need the following tools:
l
Gloves
l
Wipes
l
Isopropyl Alcohol
l
Protective, supporting material on which to rest the platform (e.g., foam)
1. Remove the payload structure, if necessary.
2. Remove the right and left side skins, and set them aside.
3. Lift and pin the drive assemblies to more easily maneuver the platform. This puts entire
robot weight on casters.
4. Place the protective, supporting material on the right side of the platform. Using the
right side prevents possible damage to the maintenance access panel.
5. Carefully tilt the platform onto its right side onto the protective, supporting material.
6. Use a wipe wetted with Isopropyl Alcohol to thoroughly clean the casters.
7. After cleaning all casters, carefully tilt the platform upright.
8. Un-pin and lower the drive assemblies.
9. Re-install the payload structure if it was removed.
10. Re-install the two side skins you removed earlier.
11. Clean the side skins if needed.
