- · Use exhaust ventilation on permanent machining jobs. - · Wear an approved respirator if there is no other way to control the dust. - · Comply with applicable rules and regulations for the work place. In the United States, use Occupational Safety and Health Administration (OSHA) requirements. These OSHA requirements can be found in '29 CFR 1910.1001'. In Japan, use the requirements found in the 'Ordinance on Prevention of Health Impairment due to Asbestos' in addition to the requirements of the Industrial Safety and Health Act. - · Obey environmental regulations for the disposal of asbestos. - · Stay away from areas that might have asbestos particles in the air. ## Dispose of Waste Properly <!-- image --> Illustration 58 g00706404 Improperly disposing of waste can threaten the environment.

Do not depend on the hydraulic cylinders to hold up the equipment. Equipment can fall if a control is moved, or if a hydraulic line breaks. Do not work beneath the cab of the machine unless the cab is properly supported. Unless you are instructed otherwise, never attempt adjustments while the machine is moving or while the engine is running. Never jump across the starter solenoid terminals in order to start the engine. Unexpected machine movement could result. Whenever there are equipment control linkages the clearance in the linkage area will change with the movement of the equipment or the machine. Stay clear of areas that may have a sudden change in clearanc…

As for installing the front guard (option), contact your KOBELCO authorized dealer. <!-- image --> ## CHECK PROTECTIVE RELATED GUARDS AND EQUIPMENT - · Check all protective related guards, covers, windows and mirrors are not damaged and secure prior to operation. If any damage or other issue is found, do not use the machine until the protective related parts and equipment has been replaced. Never attempt to repair protective related parts and equipment. - · Understand how the protective systems and the protective related equipment protects you as the operator and others around the machine. - · Never remove protective related parts and equipment from the machine. ## LIMITED PROTECTION FROM OBJECTS FALLING ON THE CAB When operating near areas where landslides may occur or where rocks or other debris may fall, be aware that the cab and the guards installed provide limited protection for the operator and may not prevent serious injury or death. - · The top guard is designed according to ISO10262 and should not allow loads up to 227 kg (500 lbs.) dropped from a height of 5.22 m (17 ft.) to penetrate the cab. During building demolition or other activities, the load, the distance of the drop, or both could produce forces that exceed the limits of the top guard and cause serious injury or death. - · Never weld, drill or modify the top guard or other protect…
