port and the grease inlet are inverted.
(Refer to Fig. 9-5 "L-Axis Speed Reducer Diagram".)
1. Make the L-arm vertical to the 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.
• If grease is injected with the plug on, the grease will leak
inside the motor and may cause a damage. Make sure to
remove the plug before the grease injection.
NOTE
• Do not install a joint, a hose, etc. to the grease exhaust
port. Failure to observe this instruction may result in
damage to the motor due to coming off of an oil seal.
4. Install a grease zerk A-MT6X1 to the grease inlet. (The grease zerk is
delivered with the manipulator.)
5. Inject grease througn the grease inlet using a grease gun.
– Grease type:
– Amount of grease:
– Air supply pressure of grease pump:
– Grease injection rate:
6. Move the L-axis for a few minutes to discharge excess grease.
7. Remove the grease zerk from the grease inlet, and reinstall the screw.
Before installing the screw, apply Three Bond 1206C on the thread
part of the screw. Then tighten the screw with a tightening torque of
10 N•m (1.0 kgf•m).
