I having trouble getting the Claymore thrower to work properly. It charges but the release pedal does nothing. It’s hard to tell but it might be cause by a lack of tension on the arm that translates the release pedal movement to get out of the way of the release arm.
Two things to check. First, make sure the linkage to the spring is not binding and the spring is cranked up pretty stiff. Second, make sure the safety pin is not engaged. - DK
