• Clean body and cable components occasionally with a damp cloth
• Frequently check the WinLock window restrictor's body fixings by manually identifying any excessive movement of the screw fixings. Should there be excessive play, remove the plastic cover caps and screws. Access the failure of the fixings and refit appropriate screws/bolts, etc. In some instances, die tap back plates and screws may have to be used. Refit caps.
• Check the anchorage of the linkage into the lock body and fixed plate by pulling the cable manually. If there is excessive movement of the cable within the anchored body, replace the complete linkage with new.
