You can try some bee's wax on the string and/or trying to tighten it by bending some of the pulleys. More than likely the string will have to be replaced. Just about every 999 I've seen had string issues.

Bees wax is the bomb! Any Ace hardware store has it. Just put it on the shaft and string and the slipping will be gone. make sure the string is not to tight causing excess friction in some of the string pulleys.
