The JLG 400S boom lift is a vital piece of equipment for high-altitude operations, widely used in construction, maintenance, and electrical industries. Its superior performance and operational flexibility make it indispensable for aerial work. However, improper use not only reduces efficiency but also poses significant safety risks. Mastering correct operating procedures is essential.

Before operation, familiarize yourself with the machine's basic structure and functions. Learn the purpose of every button and indicator on the control panel, and master key operations such as lifting, rotating, and extending the boom. A thorough pre-operation safety inspection is mandatory to confirm the equipment is in optimal condition.

Always wear proper protective gear including hard hats and safety harnesses. Ensure the work area is clear of obstacles. During operation, select appropriate work modes based on environmental conditions and task requirements. Maintain controlled lifting speeds to avoid sudden movements, and execute boom rotations or extensions smoothly to prevent collisions.

Operators must remain vigilant about the equipment's performance. Any abnormalities should prompt immediate shutdown and professional inspection.

Regular maintenance ensures safe operation. Schedule inspections of hydraulic systems, electrical components, and mechanical parts, replacing worn elements promptly. Only through professional training and continuous practice can operators fully utilize the JLG 400S boom lift's capabilities while guaranteeing worksite safety and productivity.
