New software is available for the direct replacement of former software on the models that are listed. The new software and the former software are listed in Table 1. The new software prevents damage to the work tool from an excessive flow of hydraulic fluid.

If 3 is selected for the tool control system and Hammer is selected for the tool parameter, the former software for the auxiliary hydraulic controller generated a signal for a double volume of hydraulic oil flow to the hammer. The double volume of hydraulic oil flow to the hammer could damage the work tool.

Install the new software in the field before configuring the machine to the tool parameter for a hammer.
