Shut down the machine until damaged or nonfunctioning visibility aid(s) is repaired (if applicable) or until appropriate job site organization is used to minimize hazards that are caused by any resulting restricted visibility. ## Machine Operation when the Machine is not Completely Assembled Illustration 66 <!-- image --> g02202544 Attach the tag to the controls of the machine. When the tag is attached to the controls, operate the machine as described below. If the machine needs to be operated without the boom, stick, and/or counterweight being installed, the machine should be operated slowly on flat, stable ground or pavement by qualified operators. Avoid any machine operations which could affect machine stability, including the swing function. The ROPS structural certification depends on the support of the boom, stick, and counterweight in the event of a machine tip over or a machine rollover incident. i06299648 ## Engine Stopping SMCS Code: 1000; 7000 Do not stop the engine immediately after the machine has been operated under load. Stopping the engine immediately can cause overheating and accelerated wear of engine components. After the machine is parked and the parking brake is engaged, allow the engine to run at low idle for 5 minutes before shutdown. Running the engine allows hot areas of the engine to cool gradually. i06589158 ## Lifting Objects SMCS Code: 7000 There may be local regulations and/or government regulations that govern the use of machines which lift heavy objects. Obey all local and government regulations. If this machine is used to lift objects within an area that is controlled by the European Directive '2006/42/ EC', the machine must be equipped with a boom lowering control valve, a stick lowering control valve, and an overload warning device. If this machine is used to lift objects within Japan , Japanese regulations require the machine to be equipped with a shovel crane configuration. Consult your Cat dealer for addition…

Demolition applications may generate flying debris. Ensure that there are no personnel in the area around the machine where flying debris may travel. Demolition applications may generate airborne dust that can be hazardous to your health. If you operate the machine in a dust generating applications, use appropriate safeguarding or adequate ventilation to minimize risk. i07393520 ## Parking SMCS Code: 7000 The hydraulic system controls remain pressurized if the accumulator is charged. This condition is true even when the engine is not running. The hydraulic control system pressure should decrease in a short time (approximately 1 minute). While the hydraulic controls maintain a charge, the hydraulic work tools and machine controls remain functional. There can be residual pressure within the hydraulic system even when the accumulator is empty. Refer to this Operation and Maintenance Manual, 'System Pressure Release' before any service is performed to the hydraulic system. Machine movement that is sudden and unexpected will occur if any of the controls are moved. Machine movement that is sudden and unexpected, can cause personal injury or death. Always move the hydraulic lockout control to the LOCKED position before you shut off the engine or immediately after the engine stops running. Park the machine on a hard, level surface. If you must park the machine on a grade, chock the tracks of the machine. Illustration 67 <!-- image --> g02280104 Place the machine in the servicing position. Note: Make sure that all work tools are in the recommended servicing position before servicing the machine. Move the hydraulic lockout control to the LOCKED position. Stop the engine. Turn the engine start switch to the OFF position and remove the engine start switch key. Turn the battery disconnect switch to the OFF position. Note: Do not turn the battery disconnect switch OFF until the ' Wait to Disconnect Lamp ' has turned off. If the battery disconnect switch is turn…
