PR-750B PAVEMENT PROFILER Starting Procedure Caterpillar


Starting Procedure
`
1.1. Normal Starting
2.1. Cold Weather Starting

Normal Starting

------ WARNING! ------

ENGINE NOISE CAN CAUSE HEARING DAMAGE. WEAR EAR PROTECTION WHEN WORKING CONTINUOUSLY ON OR NEAR THE MACHINE WITH THE ENGINE RUNNING.

------WARNING!--------


NOTICE

ALWAYS KEEP THE MAINFRAME AS NEAR LEVEL AS POSSIBLE.


1. Set the main battery disconnect switch at "On" if it has been turned off.

2. Set all controls at "Off" or "N" (neutral) except the park brake control. SET THE PARK BRAKE CONTROL AT "ON".

NOTE: THE TRACK DRIVE PUMP IS EQUIPPED WITH A NEUTRAL START SWITCH WHICH WILL PREVENT THE ENGINE FROM BEING STARTED IF THE TRAVEL CONTROL IS IN ANY POSITION OTHER THAN "N".

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.

------ WARNING! ------

STARTING THE ENGINE BEFORE ALL PERSONNEL ARE CLEAR OF THE MACHINE COULD CAUSE PERSONAL INJURY. SOUND THE HORN FOR SEVERAL SECONDS BEFORE STARTING.

------WARNING!--------
4. Set the throttle lever halfway between "Off" and "Increase" (half engine speed position).
5. Press the starter switch down to "Start". If the engine fails to start in a few seconds, move the throttle lever to the "Off" position and continue to crank for 10 seconds. This will clear the cylinders of unburned fuel.

If the engine fails to start after 30 seconds of cranking allow the starter to cool for 2 minutes before repeating the starting procedure.

6. 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 5 SECONDS.
7. Check the auxiliary pressure gauge. If the pressure does not reach 2250 psi (15 514 kPa) within 5 seconds, shut the engine down immediately.
8. Check the voltmeter for a reading of about 28 volts, the alternator regulated output voltage. If the reading is less, determine and correct the cause before going further. The voltmeter should remain at about 28 volts anytime the engine is running.
9. Check the track pressure gauge for a zero (0) reading. Adjust the travel control as necessary to get the zero pressure.

------ WARNING! ------

IF THERE IS PRESSURE IN THE TRACK DRIVE SYSTEM AND THE PARK BRAKE CONTROL IS MOVED TO "OFF", THE MACHINE WILL LUNGE EITHER FORWARD OR BACKWARD. PERSONAL INJURY MAY RESULT.

ADJUST THE TRAVEL CONTROLS TO NEUTRAL ("N") BEFORE MOVING THE PARK BRAKE CONTROL TO "OFF".

------WARNING!--------
10. Allow the engine to idle until all systems reach normal operating ranges. Check all gauges during the warm-up period.

Cold Weather Starting

------ WARNING! ------

STARTING FLUID IS VOLATILE AND MUST BE STORED AWAY FROM HEAT AND DIRECT SUNLIGHT. IF AN AEROSOL CONTAINER IS USED, FOLLOW THE INSTRUCTIONS ON THE CONTAINER.

------WARNING!--------


NOTICE

SPRAY STARTING FLUID ONLY WHILE CRANKING THE ENGINE. IF STARTING FLUID IS SPRAYED INTO AN ENGINE THAT IS RUNNING, THE FLUID WILL CAUSE SEVERE PREIGNITION IN ALL CYLINDERS UNTIL THE FLUID IS CONSUMED.


When starting fluid is required to start the engine, two persons must be available; one person to perform the starting procedure and one person to spray the starting fluid into one of the engine air cleaner inlets. Follow the normal starting procedure and WHILE CRANKING THE ENGINE spray starting fluid into the air cleaner inlet for 1 second. Wait at least 2 seconds before spraying starting fluid again. If the engine does not start within 30 seconds, let the starter cool for 2 minutes, then repeat the procedure.
