COCKING THE LATCH AFTER UNLOCKING (OR BEFORE LOCKING IS VERY IMPORTANT TO ASSURE PROPER FUNCTIONING. IT IS DONE BY ROTATING THE LATCH AWAY FROM THE RECEIVER AND AGAINST THE COCKING RIVET (OR THE BACK OF THE CASE/TYPE 1), UNTIL IT CANNOT BE ROTATED FURTHER (FIG. 4); FORCING IS UNNECESSARY. NOW THE HOOK OF THE SPRING IS AT THE MAXIMUM DISTANCE FROM THE HEX HOLE. THIS ENABLES THE HOOK TO 'OVER-REACH' THE RECEIVER PIN WHEN LOCKING (FIGS. 5 & 6).
 

FIG . 3B MALFUNCTION! Do Not Do This! Shown is Attempting to Lock Without Cocking First

THIS 'COCKING' ACTION FACILITATES THE 'OVER-REACH' CONDITION (FIG. 5) WHEN OPERATING LOCK, THEREBY ASSURING PROPER POSITIONING OF THE SPRING HOOK & RECEIVER PIN ELEMENTS IN THE LOCKED MODE (FIG. 6)
