The piston doesnt lock on the trigger. if trigger is adjustable set adjustment more coarse. Check also sure that trigger mechanism is in forward position and not stuck halfway. If still not hooking see if piston hooh and trigger catch not damaged. very seldom the piston will twist inside making it impossible to hook, just realign piston.

If the trigger is adjustable set it more coarse to hook the piston rod. Make sure trigger is loose and will reset to it foremost position. Check trigger spring and pin for ease op operation. Lastly check if piston rod did not turn inside cylinder so hook is turned away from trigger.

Hit the top of the barrel with your hand. Don't be afraid to give it a good whack.
