Do not stick your hand or head out of the window during crane operation. Serious injury or death can result from this practice.
Boom Elevating Control Pedal This pedal is for raising and lowering the boom. It is linked with the boom elevating control lever in motion.
WARNING Moving the control levers abruptly is dangerous because it causes the load to bounce and swing. Be sure to operate the levers slowly and carefully. The machine is not automatically stopped even if the boom is elevated to raise a dangerously heavy load clear of the ground. An overloaded machine could overturn or be damaged. Use only the hoist-up operation to raise the load clear of the ground. When the boom is lowered, the load radius increases. Be alert to any sign of overloading when lowering the boom. Do not try to pull the load inward by raising the boom. This practice can damage the crane, leading to an accident.
