. OPERATION EXPLANATION OF COMPONENTS TORQUE CONVERTER OIL TEMPERATURE 3 - 16 This torque c onverter oi l temperature gauge (1) shows the torque converter oil temperatur e. ): Indicator should be in this range during normal operations f indicator enters red range during operations, oil is overheating Range (A) (white range ): Indicat normal f indica Range (B) (red range):

I ndica operation s, oil is overhe f this hap pens, caution l amp (C) inside the orque c ights u onverter oil te p, the alarm mperature gauge buzzer sounds ntermittently, the centr al warning lamp ights up , and "E02 TC OVERHEAT" displaye d on the charac If the torque converter o il temperature gauge dis plays overheating , move the machine to a s afe place, and s top the machine. Then se t the g ear shift l ever to position N, run the engine under n o load at a mid-ran ge speed and w ait until caution lamp (C) i nside the torqu e converter oil temperature gaug e goes out . ENGINE WATER TEMPERATURE This engine water temperature g auge (2) shows the engine water temperature.

Range (A) (white range ): Indicat normal f indica Range (B) (red range): I ndica I t operation s, coolant is ov f this hap pens, caution l amp (C) inside the engine w ater temperatur e gauge lights up, he alarm buzzer sounds intermittently, the central w arning lamp lig hts up, and "E02 ENGINE OVERHEAT" i r display. s displayed on the characte If th e engine wat er temperature gauge display s overheating, move the machine to a saf e place, and s top the machine. Then se t the g ear shift l ever to position N, run the engine under n o load at a mid-ran ge speed and w ait until caution lamp (C) i nside the engin e water temper ature gauge goes out.

In addition, if the ind icator enters re d range (A), t he engine output is automatically restricted .
