Maintenance and inspection procedures 5-100
(2) Oil mist specification
1) Previously, move the J3 axis to upper end position by jog operation.
This position is necessary to set the ABS mark (marking-off line) of J4 axis after.
2) Turn off the controller's power supply.
3) Remove the four screws (M3x8) which fix the lower part of bellows to the frange.
4) Lift the bellows, and loosen the two set screws of the frange, and remove the frange.
5) Loosens the fixing screw of the bellows stop ring which is fixing the upper part of bellows, and remove
bellows.
6) Installs new bellows.
7) Installs the frange in the position of 30 mm from the shaft lower end as before. Align two set screws (M4) to
the D cut surface and fix them securely.
8) Fixes the bellows lower part to the frange as before. Fixes the four bellows fixing screws (M3x8) securely.
9) Makes the J4 axis into the position of 0 degree by jog operation etc., and match the ABS mark (marking-off
line) with ABS mark (marking-off line) on the shaft.
In the condition that each other's ABS mark has matched, fixes the bellows upper part.
10) Fixes the fixing screw of the bellows stop ring as before, and fixes the upper part of bellows securely.
The fixing screw should fix the bellows stop ring in the position used as the inner side.
(refer to figure) If that is not right, the fixing screw may interfere with the No.1 arm.
And, you should confirm that the stop ring has covered the perimeter of bellows
surely. If the fixation is not enough, the protection performance may drop.
This completes the replacing bellows.
