HARNESS AS 2595233 - Caterpillar

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 Relief" 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 (if equipped).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 turned off before the lamp has shut off, the DEF system will not purge. DEF could freeze and damage the pump and lines.Remove the disconnect switch key if you do not operate the machine for an extended period. This will prevent drainage of the battery. A battery short circuit, any current draw from certain components, and vandalism can cause drainage of the battery.Install barriers or lighting as required to prevent interference in road traffic.Select places free of danger by flooding and other water damage.
