Be sure to keep enough space and prevent the end effector hitting any peripheral
equipment.
The brake release switch affects only Joint #3. When the brake release switch is
pressed, the brake for Joint #3 is released simultaneously.
Be careful of the shaft while the brake release switch is being pressed because the
shaft may be lowered by the weight of an end effector.

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
