WARNING
• The end effector attachment must have adequate strength to withstand the
loads listed in Table 3-1. If too weak, the attachment may break during robot
operation and fragments fly off causing accidents or injuries.
• The end effector attachment must have sufficient rigidity versus the loads
listed in Table 3-1. If this rigidity is inadequate, the end effector may vibrate
during robot operation causing bad effects on the manipulator operation.
