#6 Setting up the figure-4 armbar is completed by resting your left hand, including your thumb, on your right upper forearm. Your rotation of his elbow will also have off-balanced the attacker and set him up for the throw, which should be a snap. Pardon the pun. To execute the throw simply apply a little upward pressure with your left forearm & downward pressure with your right hand. Or, as an option, you can straighten both of your arms out slightly to off-balance him. [Although this is a much easier way to off-balance your attacker, be very careful with this option though and do it very slowly in practice.] As the attacker goes up onto his toes just pivot your right foot back counterclockwise to complete the throw.
CAUTION: Setting a figure-4 armbar as instructed in this sequence will result in an extremely tight armbar at his elbow. Be sure to let up on the pressure on your uke’s elbow as you execute the throw. Otherwise a dislocated elbow may be unavoidable.
