There is a hazard of damage to the work equipment, or a hazard of serious personal injury being caused by flying pieces of broken materials, or of the machine tipping over due to reaction from the impact. q Generally speaking, the machine is more liable to overturn when the work equipment is at the side than when it is at the front or rear. q When using a breaker or other heavy work equipment, there is a hazard of the machine losing its balance and tipping over. When operating on flat ground as well as on slopes. q Do not suddenly lower, swing, or stop the work equipment. q Do not suddenly extend or retract the boom cylinder. There is a hazard that impact will cause the machine to tip over.
