1. Remove the hexagon socket head plugs PT1/8 from the grease
exhaust port.
• If grease is injected with the plug on, 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 dam-
age to the motor due to coming off of an oil seal.
2. Remove the hexagon socket head plugs PT1/8 from the grease inlet
and install a grease zerk A-PT1/8.
3. Inject grease into the grease inlet using a grease gun.
(The grease zerk is delivered with the manipulator.)
– Grease type:
– Amount of grease:
– Air supply pressure of grease pump:
– Grease injection rate:
4. Move the L-and U-axes for a few minutes to discharge excess grease.
5. Wipe the discharged grease with a cloth, and reinstall the plug. Before
installing the plug, apply Three Bond 1206C on the thread part of the
plug. Then tighten the plug with a tightening torque of 4.9 N•m (0.5
kgf•m).
