Before lifting, what must be verified after outriggers contact surface?

• A. Fuel level
• B. Battery status
• C. Cabin air quality
• D. Leveling must be verified

Answer: (D)

Stability is the key factor here: the base must be level before any lift begins. Once the outriggers touch the surface, leveling the chassis ensures the load and boom operate within design tolerances and keeps the platform from tipping or shifting under load. If the base isn’t level, uneven support can cause the boom to tilt, place abnormal stresses on the structure, or even lead to a tip-over. Use a level or the lift’s leveling indicators, adjust each outrigger jack or pad as needed, and recheck after any movement or surface change. Only proceed with lifting when the base is confirmed level in all directions.
