Personal injury or death can result from improperly checking for a leak.Always use a board or cardboard when checking for a leak. Escaping air or fluid under pressure, even a pin-hole size leak, can penetrate body tissue causing serious injury, and possible death.If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.
Personal injury or death can result from sudden work tool movement.Sudden movement of the work tool can cause injury to persons near the work tool.To prevent injury or death, make sure that the area around the work tool is clear of personnel and obstructions before operating the work tool.
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
Personal injury can result from flame cutting or welding on painted areas.The effect of gasses from burned paint is a hazard to the person doing the cutting or welding.Do not flame cut or weld on painted areas.
Before carrying out arc welding on the machine or on any equipment attached to the machine, disconnect all power and ground leads from the batteries in order to avoid possible damage to electronic components.

Updating ECM Settings: Reference the following description for selecting the proper "Quick Coupler Configuration". There are either one or two parameters to update, depending on the machine software and system installed.
Parameter: "Quick Coupler Installation Status" (ET) "Quick Coupler" (Monitor)
Not Installed: "Quick Coupler" control system is not installed on the machine.
Installed without Coupler Accelerator: This setting is the traditional North American setting that only applies voltage to the coupler valve when the switch is flipped. This setting is used with the "Center Lock" pin grabber, and new ISO CAT pin grabber couplers. This setting can also be used on the machines with the universal coupler.
Installed with Coupler Accelerator: This setting is used on machines with universal coupler control circuit, traditionally EAME machines. Except for ACS machines 336E H, 336FXE, 374F, 390F, the machine must have the added hardware for this feature. In addition to applying voltage to the "Quick Coupler" valve, the added hardware also energizes another solenoid that causes pump pressure to rise. This is often done through shifting the boom 2 spool in the reverse direction to block the NFC open center passage, causing NFC pressure to drop the pump to stroke up. Because the universal coupler control valve is plumbed to the pump discharge pressure tap, it will immediately receive pressure to start unlocking the coupler before the operator has moved the joystick. This setting is not to be used with the center lock or old pin grabber and
