9.3 Grease Exchange Procedures
3. Install grease zerk A-PT1/8 on the Si grease inlet, then inject grease.
Grease Type: Molywhite RE No.00
Amount of Grease: 60 g (120 g for 1st supply)
Air Supply Pressure of Grease Pump: 0.3 MPa or less
Grease Injection Rate: 8 g or less
4. Move the S-axis for a few minutes to discharge excess grease.
5. Wipe off the exhausted grease with a cloth, and reinstall the hexagon
socket head plugs PT1/8 on the Si grease inlet and the So grease
exhaust port. Apply ThreeBond 1206C to the thread parts.
 Grease Exchange
(Refer to Fig. 9-5 "S-Axis Speed Reducer (After the Cover Removal)".)
1. Posture the R- and L-axes as shown in Fig. 9-5.
2. Remove the hexagon socket head plugs PT1/8 on the So grease
exhaust port and the Si grease inlet.
If grease is added without removing the hexagon socket
head plugs PT1/8, the internal pressure will increase and
NOTE
may cause a damage.
Never fail to remove the hexagon socket head plugs PT1/8
before the grease injection.
3. Install grease zerk A-PT1/8 on the Si grease inlet, then inject grease.
Grease Type: Molywhite RE No.00
Amount of Grease: Approx. 240 g
Air Supply Pressure of Grease Pump: 0.3 MPa or less
Grease Injection Rate: 8 g or less
4. The grease exchange is complete when the old grease is drained off
and the new grease appears in the So grease exhaust port. (The new
grease can be distinguished from the old grease by color.)
5. Move the S-axis for a few minutes to discharge excess grease.
6. Wipe off the exhausted grease with a cloth, and reinstall the hexagon
socket head plugs PT1/8 on the Si grease inlet and the So grease
exhaust port. Apply ThreeBond 1206C to the thread parts.
