1. Make the L-arm vertical to the ground.
2. Remove the hexagon socket head plug PT3/8 from the grease
exhaust port.
3. Remove the hexagon socket head plug PT1/8 from the grease inlet.
4. Install the grease zerk PT1/8 to the grease inlet.
(The grease zerk is delivered with the manipulator.)
5. Inject grease through the grease inlet using a grease gun.
– Grease type:
Cassida Grease EPS 00
– Amount of grease:
approx. 1650 cc
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate:
8 g/s or less
6. The grease discharge is complete when new grease appears from the
exhaust port. The new grease can be distinguished from the old
grease by color.
7. Move the L-axis for a few minutes to discharge the excess grease.
8. Wipe the discharged grease with a cloth and reinstall the hexagon
socket head plug PT3/8 to the exhaust port.
Before installing the plugs, apply Three Bond 1206C on the thread part
of each plug, then tighten the plug with a tightening torque of 23 N•m
(2.3 kgf•m).

NOTE
• If grease is injected with the exhaust plug on, grease will
leak inside the motor and may cause a damage. Make
sure to remove the plug before the grease injection.
• 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.
NOTE
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.
