PREPARING THE MACHINE START 11 - CHECK SAFETY BELT Danger of injury! A damaged safety belt or a safety belt that has been stretched in an accident does no longer protect you! Have the safety belt replaced by an expert, if it is damaged or if the machine has been involved in an ac- cident. The belt must not be twisted or caught between parts, nor must it chafe at sharp edges. The socket for the lock tongue must not be blocked by paper or the like, since this will make engaging of the lock tongue impos- sible. Keep the belt clean and check that the belt fixings are tightly fastened. Replace the safety belt, if the belt or the belt fixings are damaged or deformed.
12 - CHECK ROPS Check whether screws are loose or damaged. Have loose screws tightened and damaged screws replaced by a Komatsu dealer. Loose screws must only be tightened with the specified tightening torque. Damaged screws must only be replaced by original parts. 13 - CHECK CAB WINDOWS Prior to start of work, clean the cab windows. 14 - PERFORM THE OPERATIONS INDICATED IN CHAPTER "24. Maintenance Prior to Start". (See also "23. Maintenance Schedule"). 76
