Lubricate chains and cables. Rust can work its way into piston housings, lift columns, chains, cables, and bearings and obstruct the lift. Inspect end connections for corrosion or fatigue, excessive wear, connection hole elongation, or deformation.
Check sprockets and pulleys for wear and damage.
They must roll freely. Keep them lubricated. Examine coatings and sheaths on cables for wear. Inform your supervisor immediately of any damage you find. All worn or damaged parts must be replaced by qualified lift service personnel.
