To attach the lower bellows, move the shaft to its upper limit.
To move the shaft up/down, press and hold the brake release switch.
Be sure to keep enough space and prevent the end effector hitting any peripheral
equipment.
The brake release switch is applied to both Joints #3 and Joint #4.
When the brake release switch is pressed, the respective brakes of the Joint #3 and
Joint #4 are released simultaneously.
Be careful of the shaft falling and rotating while the brake release switch is being
pressed because the shaft may be lowered by the weight of an end effector.
The bellows has two joints:
The larger joint must be attached to the cover
side.
The smaller joint must be attached to the end
face side of the shaft.
Attach the mounting part of the bellows until
the end touches the cylindrical part of the
cover.
Then, secure them with clamp bands.
Cover the bearing case (black) on the edge of
the shaft with the bellows mounting part.
Then, secure them with clamp bands.
