Troubleshooting - Napa Carlyle Tools 791-6450 Operating Manual

INSPECTION
Visual inspection should be made before each use of the jack, checking for leaking hydraulic fluid and damaged, loose or missing parts.
Each jack must be inspected by a manufacturer's repair facility immediately if subjected to an abnormal load or shock. Any jack which
appears to be damaged in any way, is found to be badly worn, or operates abnormally MUST BE REMOVED FROM SERVICE until necessary
repairs are made by a manufacturer's authorized repair facility. It is recommended that an annual inspection of the jack be made by a
manufacturer's authorized repair facility and that any defective parts, decals or warning labels be replaced with manufacturer's specified
parts. A list of authorized repair facilities is available from the manufacturer.
PROPER STORAGE
It is recommended that the jack be stored in a dry location with all wheels touching the ground on a relatively level surface.
