ATTENTION: DO NOT tip the machine onto its side to replace parts or perform any
maintenance procedures. Sensitive robotic components could be damaged or bumped
out of adjustment if the machine is tipped onto its side.
ATTENTION: DO NOT remove and/or adjust the upper or lower LIDARs, any of the
3D cameras, or remove/move shrouds or brackets on which these components are
mounted. Due to calibration the LIDARS and 3D cameras cannot be adjusted in the fi eld.
