Grease Replenishment
(Refer to "Fig. 25 L-axis Speed Reducer Diagram".)
Replenish the grease in accordance with the following procedure:
1. Posture the L-axis vertical to the ground.
2. Remove the plug and the screw from grease exhaust port and grease inlet respec-
tively.
3. Install the grease zerk A-MT6X1 on the grease inlet. (The grease zerk A-MT6X1 is
delivered with the manipulator.)
4. Inject the grease into the grease inlet using a grease gun.
5. Move the L-axis for a few minutes to discharge the excess grease.
6. Remove the grease zerk and reinstall the hexagon socket head cap screw M6 on the
grease inlet. Tighten the screw with a tightening torque of 5 N·m (0.51 kgf·m). Apply
Three Bond 1206C on the thread part of the screw.
The exhaust port and the grease inlet are inverted in case of ceiling installation.
If grease is injected with the plug on, the grease will go inside the motor and may damage
it. Never fail to remove the plug before the grease injection.
