Reducer.)
1. Remove the hexagon socket head plug 3/8 from the grease exhaust
port.
2. Remove the hexagon socket head plug PT1/8 from the grease inlet
and install the grease zerk PT1/8. (The grease zerk is delivered with

3. Inject grease through the grease inlet using a grease gun.
– Grease type: Molywhite RE.No.00
– Amount of grease: 700 cc
(1400 cc for 1st supply)
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less
4. Move the R-axis for a few minutes to discharge excess grease.
5. Wipe the discharged grease with a cloth and reinstall the plug PT3/8
on the grease exhaust port. Apply Three Bond 1206C to the thread
part of the plug, and tighten the plug with a tightening torque of 23 N
•m
(2.3 kgf
•m).
6. Remove the grease zerk from the grease inlet and reinstall the plug
PT1/8. Apply Three Bond 1206C to the thread part of the plug, and
tighten the plug with a tightening torque of 4.9 N
•m (0.5 kgf•m).
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.
