Bellows
Installation
(1) To attach the 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.
Be careful of the shaft falling while the brake release switch is being pressed because
the shaft may be lowered by the weight of an end effector.
(2) Pass the shaft through the bellows from the larger joint.
(3) Secure the cover side of the bellows.
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.
Be careful not to misplace the clamp bands. The
clamp band has two sizes; small and large.
Attach the mounting part of the bellows until the
end touches the cylindrical part of the cover.
