6. For the point where grease is exchanged, perform a playback
operation indicated in table 9-7 “Running-in Operation of Each Axis”
for running-in the speed reducer with the grease.
At this time, in case grease is discharged during the operation, remove
the grease zerk from the grease inlet, clean and degrease the tap part
and the thread part of the plug. And then, apply ThreeBond 1206C to
the thread part of the plug to mount the plug to the grease inlet.
Tighten the plug with the tightening torque indicated in table 9-8 “Plug
Type and Tightening Torque of Each Axis” . Also, discharge the
excess grease not to increase the inner pressure of the speed reducer.
Attach a bag to receive grease such as indicated in fig. 9-8 “Grease
Receiving Bag (Rough Standard)” , and then perform the running-in
operation.
