6-2 Non-periodic Maintenance
This section provides information and instructions for performing maintenance that does not occur at
regular intervals.
WARNING
• Never connect or disconnect system cables while power is applied to the robot.
Failure to comply may cause unexpected behavior and can result in personnel in-
jury and equipment damage.
• You must perform the Lockout and Tagout procedure prior to servicing the robot.
• The procedures and replacement of the parts mentioned in this manual must be
performed only by the skilled or instructed persons.
• The access covers on the robot are not interlocked. You should turn OFF and dis-
connect the power before the covers of the robot are removed.
6-2-1
Replacing the Tool Flange
Replace the tool flange if it gets damaged.
Before beginning the procedure, have the following tools available.
• 2.5 mm hex bit
• 3 mm hex bit
• Torque wrench
• Loctite thread lock type 243 or equivalent
• Loctite thread lock type 222MS or equivalent
DANGER
Failure to ground robot-mounted equipment or tooling that uses hazardous voltages
could lead to injury or fatality of a person touching the end-effector during an electrical
fault.
WARNING
If air pressure is present, disconnect it from the robot when servicing end-of-arm tool-
ing or other pneumatic components to prevent unsecured pneumatic air lines from ac-
cidentally injuring personnel.
Precautions for Safe Use
The Joint 3 quill and the tool flange are not grounded to protective earth. If hazardous voltages
are present at any user-supplied robot-mounted equipment or tooling, you must install a ground
connection from that equipment or tooling to the ground point on the robot base.
Refer to
3-10-1 Grounding the System on page 3-44 for more information about grounding the
Tool Flange.
Precautions for Correct Use
When removing and replacing the tool flange, you must reinstall it in the same position to avoid
losing the calibration for the robot.
