bellows, move the shaft to its lower limit.
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 #4. When the brake
release switch is pressed, the respective brakes of the Joints #3 and #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.

Pass the shaft through the bellows
from the larger joint.

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 three sizes;
small, medium,
and large.
Attach the mounting part of the bellows
until
the end touches the
cylindrical part of the cover.
Attach the rubber sheet. Be sure to attach the
rubber sheet so that no space is made between
the bias cut. (No rubber sheet for the
