Normal Starting
| NOTICE |
|---|
ALWAYS KEEP THE MAINFRAME AS NEAR LEVEL AS POSSIBLE. EXTREME TILTING OF THE MAINFRAME CAN CAUSE LEG DAMAGE. |
 |
TO PREVENT HEARING DAMAGE, WEAR EAR PROTECTION WHEN WORKING CONTINUOUSLY ON OR NEAR THE MACHINE WITH THE ENGINE RUNNING. |
 |
To start the engine normally:
- 1. Check that the travel control is at "N", and the cutter, conveyor, front elevation and right rear elevation controls are at "Off".
- 2. Move the throttle lever forward to part throttle, then bring it back to the desired no-load speed.
- 3. Insert the key into the ignition switch and turn it to the "On" position. Check the voltmeter for a reading of 24 volts. If the voltage is low it is an indication of a bad battery.
|
BE SURE ALL PERSONNEL ARE CLEAR OF THE MACHINE BEFORE STARTING THE ENGINE. SOUND THE HORN FOR SEVERAL SECONDS BEFORE STARTING, TO WARN ANY UNOBSERVED PERSONNEL. |
|
- 4. Move the starter switch to "Start".
If the engine fails to start after 30 seconds of cranking, allow the starter to cool for 2 minutes before repeating the starting procedure. If the engine fails to start after four attempts, make an inspection to determine the cause.
- 5. Release the starter switch as soon as the engine starts and check for an immediate indication on the engine oil pressure gauge. STOP THE ENGINE IMMEDIATELY IF THERE IS NO ENGINE OIL PRESSURE WITHIN 10 to 15 seconds.
- 6. Check the voltmeter for a reading of about 28 volts, the alternator regulated output voltage. If the voltage does not increase from that noted in step 3, the charging system is not operating properly. The voltmeter reading should remain at about 28 volts anytime the engine is running.
- 7. Allow the engine to warm up at part throttle and no-load for about five minutes or until it and the hydraulic oil approach operating temperatures.
- 8. While the engine is warming up, open the engine cowling and make a visual inspection of the turbocharger for leaks and excessive vibration. Stop the engine immediately if there is any unusual noise in the turbocharger.

WHEN PROLONGED ENGINE IDLING IS NECESSARY, MAINTAIN AT LEAST 800 RPM. |
During long engine idling periods, the engine coolant temperature will fall below the normal operating range. The incomplete combustion of fuel in a cold engine will cause crankcase dilution, formation of lacquer or gummy deposits on the valves, pistons and rings and rapid accumulation of sludge in the engine.
