Always check the simplest possible cause of a malfunction first. For example, a loose or disconnected trigger
line. Then proceed logically, eliminating each possible cause until the defective part is located. Where possible,
substitute known good parts for suspected defective parts. Use Trouble Shooting Chart as an aid for locating
and correcting trouble.
