1. Remove the hexagon socket head plug PT3/8 from the exhaust port.
• If grease is injected with the bolt on, grease will leak inside
the motor and may cause a damage. Make sure to
remove the bolt 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.

3. Inject grease through the grease inlet using a grease gun.
– Grease type:
– Amount of grease:
– Air supply pressure of grease pump:
– Grease injection rate:
4. 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.
5. Move the B-axis for a few minutes to discharge the excess grease.
6. Wipe the discharged grease with a cloth and reinstall the hexagon
socket head plug PT3/8 to the exhaust port.
Before installing the plug, 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).
7. Remove the grease zerk from the grease inlet and reinstall the
hexagon socket head plug PT1/8.
Before installing the plug, apply Three Bond 1206C on the thread part
