Grease Exchange (Refer to "Fig. 24 L-axis Speed Reducer Dia-
gram.")
1. Make the L-arm vertical for ground.
2. Remove the hexagon socket head plug PT1/8 from the grease exhaust port.
3. Remove the hexagon socket head cap screw M6 from the grease inlet and install the
grease zerk A-MT6 x 1. (The grease zerk is delivered with the manipulator.)
4. Inject the grease into the grease inlet using a grease gun.
The grease exchange is complete when new grease appears in the grease exhaust
port. The new grease can be distinguished from the old grease by color.
5. Move the L-axis for a few minutes to discharge the excess grease.
6. Remove the grease zerk A-MT6 x 1 from the grease inlet and reinstall the screw M6.
Apply the Three Bond 1206C on the screwed part of the screw.
7. Wipe the grease exhaust port with a cloth and reinstall the plug PT1/8. Apply the
Three Bond 1206C on the screwed part of the plug.
