Lubrication Procedure
1. Turn off main power to the PLC Server and robot.
2. Remove the outer link cover by removing six screws located on the sides and top
of the cover. Carefully remove the cover.
3. Move Joint 3 to the top of its travel. Remove any existing grease with a soft cloth.
4. Using a syringe, apply a small bead of grease to the Joint 3 ball screw grooves (see
Figure 8-1 on page 150).
5. Move Joint 3 to the bottom of its travel. Remove any existing grease with a clean,
lint-free, soft cloth.
6. Apply a thin film of grease to any grooves of the ball screw that you did not reach
in step 4.
7. Move Joint 3 up and down several times to spread the grease evenly.
8. Replace the outer link cover and tighten the screws to 1.6 N•m (14 in-lb) of
torque.
CAUTION: Using improper lubrication products on the
Adept Cobra PLC 600 or PLC800 robot may cause damage
to the robot.
WARNING: When the Outer link cover is removed, you
see the label shown in Figure 2-3 on page 23. Do not
remove the J3-ENC or J4-ENC encoder cable connectors
from their sockets. If they are removed, the calibration
data will be lost and the robot must be run through a
factory calibration process, which requires special
software and tools.
