Lubricating Joint 3
The joint 3 quill needs to be lubricated on a periodic basis of 3 months or 150 km of linear travel,
whichever comes first.
Precautions for Correct Use
Only use the recommended grease on the joint 3 quill. Use THK AFF Grease (part number
20950-000). Refer to the provided Safety Data Sheet for proper handling.
Joint 3 Lubrication Procedure
Use the following procedure to lubricate joint 3.
Precautions for Safe Use
The braking mechanism operates passively. If 24 VDC Control Power is removed from the system,
the brake mechanism will automatically activate. 24 VDC Control Power must be supplied to re-
lease the brake. To prevent possible damage to the equipment, remove any payload from the end-
of-arm tooling, make sure that Joint 3 is supported while releasing the brake, and verify that the
end-of-arm tooling or other installed equipment is clear of all obstructions.
Precautions for Correct Use
Avoid rotating the quill / Joint 4 when the brake is released. This could result in an out-of-range
condition and may prevent program execution.
Additional Information
Ensure there are no z-axis motion restrictions. The full operating stroke is required during this lubri-
cation procedure.
