Some parts are heavy. Be careful when handling them. Lifting equipment is needed when parts weigh

150 pounds (68 kg) for a three or more person lift. Do not try to handle heavy parts without lifting
equipment. Keep clear of heavy parts supported only by lifting equipment. Failure to observe this
precaution could cause serious injury or death of personnel.
