Daily Inspection & Maintenance
1. Cleanliness: Cables, Columns, Runways and other lift parts should be kept free of corrosive agents, sol
vents, and road salts. If such agents are spilled or splashed on any lift component, immediately
rinse thoroughly with water and wipe down with a clean rag. Spray wire rope cables as required
with Penetrating Oil and wipe down.
Failure to keep lift free of corrosive agents and solvents will lead to reduced component service life, cable
failure, etc., which could result in property damage and/or personal injury.
2. Fasteners: Check all the attaching bolts and nuts for tightness.
