Personal injury could result from the sudden movement of the blade when the centershift lockpin is released.Before releasing the centershift lockpin be sure that all personnel are clear of the blade area, the circle and blade are centered under the machine and the blade has been lowered to the ground.
Personal injury or death can occur from not following the proper procedure or the recommended tooling.To prevent the possibility of injury or death, follow the established procedure using the recommended tooling.
Bring the machine to a safety state by stopping the machine on a flat and stable surface, applying the parking brake, grounding all implements, and stopping the engine. Take precautions to prevent unintended motion.
