  4. Insert the ATCart wheel motor to each of shaft holder, then lock the wheel’s shaft with holder by hex nut screw, and finally insert the brake screw to wheel’s shaft as following image.

Note

The brake screw is also known as the “parking brake”. It is used to keep the ATCart securely lock or motionless when not in use (or parked). To engange the parking brake, slightly loose the brake screw (thumbscrew) about 3-5 turns or until no tension. To release the parking brake, turn the brake screw back tightly enough (but don’t over-tighten), then the Cart is ready for moving.
