1. Remove the hexagon socket head plug PT1/8 from grease exhaust
port.
2. Remove the hexagon socket head plug PT1/8 from the grease inlet.
3. Install a grease zerk PT1/8 to the grease inlet. (The grease zerk is
delivered with the manipulator.)
4. Inject grease througn the grease inlet using a grease gun.
– Grease type:
VIGO Grease RE No. 0
– Amount of grease:
45 cc (90 cc for 1st supply)
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate:
8 g/s or less
5. Move the E-axis for a few minutes to discharge excess grease.
6. Remove the grease zerk from the grease inlet, 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).
NOTE
For the ceiling-mounted manipulator, the grease exhaust
port and the grease inlet are inverted.

NOTE
• 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.
• 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.
