crusher Whenever a jaw crusher is off and at rest (stopped), it will remain in the open position at its open-side setting (OSS). However, the adjustment of your crusher is performed at its closed-side setting (CSS). OSS is measured while the crusher is stopped. CSS is calculated by deducting a certain amount (the average stroke) from the OSS.
