10.2.1.3 Grease Replenishment Procedures for S-,L-, and U-axis Speed Reducer
 Grease Replenishment
1. Remove the plug on the Ro (Bo, To) exhaust port.
2. Remove the plug on the Ri (Bi, Ti) grease inlet, and install the grease
zerk PT1/8. Inject grease by using a grease gun.
– Grease type: VIGO grease RE No. 0
– Amount of grease: R-axis: 25 cc (22 g)
(35 cc (30 g) for the 1st supply)
B-axis: 25 cc (22 g)
(35 cc (30 g) for the 1st supply)
T-axis: 20 cc (17 g)
(30 cc (26 g) for the 1st supply)
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less
3. Before re-installing a plug to Ro (Bo, To) exhaust port, move each axis
for a few minutes to discharge excessive grease.
4. Wipe the discharged grease with the cloth when the grease is
discharged completely, and reinstall the plug. (Apply seal tape on the
thread part of each plug.)

NOTE
If grease is injected with the plug (Ro, Bo, To) on, the
grease will go inside the motor and may cause a damage.
Make sure to remove the plug (Ro, Bo, To) before the
grease injection.
Note that grease replacement is not necessary for R-, B-,
and T-axes.
