Slack is accumulated when your winch hook is stowed without tension on the cable. Slack accumulation in the wraps of the cable will cause tangling. The next time the winch is used, the top two wraps will be pulled down between the loose underlying wraps, causing pinching, flattening and fraying of the cable. Over time, this will ultimately result in cable failure and potential danger to the winch operator. Winch owners have been seriously injured and even killed due to winch line failure. Using a Winch Saver in the proper manner will prevent this from happening. Because the Winch Saver is holding tension on the cable while the winch is not in use, accumulation of slack is prevented.
