The electronic controller is located inside the front access door on the left side of the machine.If a machine or a tool malfunctions, the operator may need to report the information that is stored in the electronic controller.Turn the engine start switch to the ON position in order to activate the electronic controller.

The illustration shows an electronic controller (typical example).When you activate the electronic controller, read the digital display from left to right. The second digit and the third digit display the version of software. The fourth digit and the fifth digit indicate the number of programmed changes that have been saved for the active mode. (The active mode is determined by the position of the ball valve and of the switch for the hydraulic attachment.)The electronic controller can display the number of hours that have elapsed in each of the four flow modes. Likewise, the electronic controller can display the settings for the engine speed of the four flow modes and for the hydraulic oil flow of the four flow modes.Push switch (1) in order to scroll through the digital readouts that pertain to the different flow modes. The first number that is displayed indicates the amount of hours that have elapsed in the active flow mode. The first digit of this number indicates the number that is assigned to the flow mode. The second digit displays an "h". The "h" means hours. The last four digits indicate the number of hours of machine operation.Push switch (1) again in order to display the engine speed setting. The first digit that is displayed indicates the number that is assigned to the flow mode. The second digit displays an "E". The "E" means engine speed. The third digit and the fourth digit indicate the engine speed setting. The engine speed setting determines the speed of the engine. The engine speed will be equal to one of the ten positions of the engine speed dial. This occurs when the hydraulic attachment circuit is activated. If the setting of the electronic controller for the active mode is at "5", the engine will run at a speed that is equal to the setting at the fifth position of the engine speed dial.Note: There are two speeds that are set by the electronic controller and by the engine speed dial. During operation of the hydraulic attachment circuit, the engine will operate at the lower speed. The operator should always set the engine speed dial to at least the engine speed setting that is indicated on the electronic controller for the active mode.The fifth digit shows either an "H" (high flow) or an "L" (low flow). If the "rabbit" side of the switch for the hydraulic attachment is depressed, an "H" is displayed. If the "tortoise" side of the switch for the hydraulic attachment is depressed, an "L" is displayed.The sixth digit shows a "1" (one-way flow) or a "2" (two-way flow). If the ball valve is positioned parallel to the hydraulic
