Stem Nut (23) (Trigger in locked position).
4. Holding Trigger (20) firmly against lugs of Trigger Lock (25), tighten
Trigger Guide (17) against back surface of Trigger (20).
5. Turn Trigger Guide (17) one-half turn away from the Trigger (20) and
securely tighten Stem Nut (23) against Trigger Guide (17) while using a
1/2" open end wrench to keep Trigger Guide (17) from turning.
