Operator Certification Requirements

Operators of the JLG T350 must hold a valid certification issued by an accredited training provider or the manufacturer. The certification process includes a written examination that tests knowledge of the lift’s specifications, load charts, and safety procedures, followed by a hands‑on practical assessment where the candidate demonstrates proper platform positioning, load handling, and emergency shutdown techniques. The certification record must be maintained in the operator’s logbook and updated whenever the lift’s configuration changes, such as the installation of a new load‑bearing accessory or a modification to the hydraulic system. Operators are required to complete a refresher course at least every two years to stay current with any changes in regulations, equipment upgrades, or revised operating procedures. In addition, operators must be familiar with the specific model variant they are using, as certain T350 models have different maximum reach heights or load capacities. The certification must also cover the use of personal protective equipment, the correct procedure for securing the platform, and the steps to take when encountering an obstacle or unstable footing. Failure to meet these certification requirements can result in penalties, suspension of operating privileges, or increased liability for the operator and the employer. Therefore, maintaining up‑to‑date certification and training records is essential for safe operation and compliance with industry standards. All certifications must be logged and verified annually safety.

Starting and Stopping Procedures

Before operating the JLG T350, the operator must perform a visual inspection of the lift, ensuring that all safety devices are functional and that the platform is free of debris. The operator should check the hydraulic fluid level, confirm that the battery is charged, and verify that the load chart is accessible. To start the machine, the operator presses the start button located on the control panel while the lift is in the neutral position. The system will perform a self‑check; if any fault codes appear, the operator must resolve the issue before proceeding. Once the self‑check passes, the operator selects the desired platform height using the joystick or the foot‑pedal controller. The lift will ascend until the platform reaches the set height, at which point the operator can secure the load. When stopping, the operator first lowers the platform to the ground level or to a safe height, then presses the stop button. The hydraulic system will engage the brakes, and the lift will come to a complete halt. The operator should then disengage the battery, lock the control panel, and perform a post‑operation inspection to ensure no damage or leaks are present. These procedures help maintain safe operation and prolong the life of the equipment. Before each shift, operators must check that the hydraulic reservoir is at the level, inspect hoses for leaks, ensure the seat is adjusted, and verify the emergency stop button works; only then may the lift be powered on.

Load Handling and Lifting Operations

Before lifting, the operator must verify that the load does not exceed the capacity and that the center of gravity is within the platform’s safe zone. The operator should secure the load ensuring that all fasteners are tightened and that the load is evenly distributed. The lift’s hydraulic system is designed to provide motion; the operator should use the joystick or foot‑pedal controller to raise the platforms, maintaining a speed to avoid sudden jerks. While lifting, the operator must keep the platform level and monitor the load’s balance; if the load shifts, the operator should pause, readjust, and resume. The operator should also keep the platform within the reach of 10 ft and avoid over‑extending the lift. When lowering the load, the operator should descend at a controlled rate, keeping the load stable and preventing it from swinging. The operator must also be aware of the surrounding environment, ensuring that no personnel or equipment is in the lift’s path. After the load is placed, the operator should lock the platform, disengage the hydraulic system, and secure the lift. The operator should perform a post‑operation inspection, checking for any damage, leaks, or loose components. Proper load handling reduces wear on the hydraulic system and extends the lift’s service life. All procedures must be followed in accordance with the JLG T350 manual and company’s safety policies. Failure to comply can result in equipment damage or personal injury.
