EXPLANATION OF COMPONENTS OPERATION CHARGE LAMP This lamp (6) indicates malfunction of the alternator. When the starting switch is turned ON, it will light up, but it should go out when the engine speed rises. If the lamp lights up during operation, stop the engine and check the V-belt tension. If any abnormality is found, see "OTHER TROUBLE (PAGE 3-116)". ENGINE OIL PRESSURE CAUTION LAMP This lamp (7) warns that the engine lubricating oil pressure has dropped. When the starting switch is turned ON, it will light up. When the lamp goes off after the engine is started, the oil pres- sure is normal. When the lamp lights up during operation, the oil pressure is lower.
Immediately stop the engine and look for the cause. For details, see "OTHER TROUBLE (PAGE 3-116)". GLOW SIGNAL LAMP This lamp (8) indicates the electrical intake air heater is red- heated. While preheating is being carried out with the glow switch, the lamp lights up. In the case of automatic preheating, the lamp goes out when the preheating is completed. In the case of manual preheating, the lamp goes out when the glow switch is released. TRANSMISSION OIL TEMPERATURE CAUTION LAMP This lamp (9) warns the operator that the oil temperature at the transmission outlet port has risen.
If the lamp lights up, stop the machine, run the engine under no load at a midrange speed, and wait for the transmission oil temperature gauge (3) to go down to the white range. 3-8
