5 OPERATING THE ENGINE ENGLISH 4. Insert the key into the key switch and turn it to the "OPERATION" position. 8. Warm up the engine at medium speed without load. A If the glow lamp should redden too quickly or too slowly, immediately ask your KUBOTA dealer to check and repair it. A If the engine does not catch or start at 10 seconds after the starter switch is set at "STARTING" position, wait for another 30 seconds and then begin the engine starting sequence again. Do not allow the starter motor to run continuously for more than 20 seconds. COLD WEATHER STARTING If the ambient temperature is below -5 C(23 F)* and the engine is very cold, start it in the following manner:
Take steps (1) through (4) above. (A) "OFF" SWITCHED OFF (B) "ON" OPERATION (C) "GL" PREHEATING (D) "ST" STARTING (A) "GL" PREHEATING (B) "OFF" SWITCHED OFF (C) "ON" OPERATION (D) "ST" STARTING 5. Turn the key to the "PREHEATING" position and keep it there for a certain period mentioned below. 5. Turn the starter switch to the "PREHEATING" position to allow the glow lamp to redden. A Shown below are the standard preheating times for various temperatures. This operation, however, is not required, when the engine is warmed up. (with lamp timer in use) A The glow lamp goes out in about 5 seconds when the lamp timer is up. Refer to this for pre-heating.
Even with the glow lamp off, the glow plug can be pre- heated by turning the starter switch to the "PREHEATING" position. 6. Turn the key to the "STARTING" position and the engine should start. Release the key immediately when the engine starts. 7. Check to see that the oil pressure lamp and charge lamp are off. If the lamps are still on, immediately stop the engine, and determine the cause. (See "CHECKS DURING OPERATION" in "OPERATING THE ENGINE" section.) 6. Turn the key to the "STARTING" position and the engine should start. (If the engine fails to start after 10 seconds, turn off the key for 5 to 30 seconds.
Then repeat steps (5) and (6).) A Do not allow the starter motor to run continuously for more than 20 seconds. A Be sure to warm up the engine, not only in winter, but also in warmer seasons. An insufficiently warmed-up engine can shorten its service life. A When there is fear of temperature dropping below -15 C (5 F) detach the battery from the machine, and keep it indoors in a safe area, to be reinstalled just before the next operation. A If the oil pressure lamp should be still on, immediately stop the engine and check; - if there is enough engine oil. - if the engine oil has dirt in it. - if the wiring is faulty.
