1. Remove the hexagon socket head plug PT1/8 from the exhaust port.
2. Remove the hexagon socket head plug PT1/8.
3. Inject grease through the grease inlet using a grease gun.
– Grease type:
Molywhite RE No. 00
– Amount of grease:
approx.300 cc
(600 cc for 1st supply)
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate:
8 g/s or less
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-axes for a few minutes to discharge the excess grease.
6. Wipe the discharged grease with a cloth and reinstall the hexagon
socket head plug PT1/8 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 4.9 N•m
(0.5 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
of each plug, then tighten the plug with a tightening torque of 4.9 N•m
(0.5 kgf•m).

NOTE
• 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.
• 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.
