Leadscrew maintenance statement
While under optimal conditions lubrication interval is expected to occur approximately once every 1000 hours of service. Actual life will depend on application and environment. Based upon this, frequent inspections must be performed and a maintenance interval determined based on actual conditions.
Recommended lubricant: Dupont Krytox GPL 206
