Starting requires that clean air and fuel be supplied to the combustion chambers in the proper quantities at the correct time.
Normal Starting Procedure
Warning: Before starting be sure that everyone is clear of the engine and equipment.
If the fuel system is equipped with an over speed stop, push the “Reset" button before attempting to start the engine.
1. On units equipped with an air activated prelubedevice.open the air valve to activate the piston in the prelube device which will lubricate all moving parts in the engine.
Note: On engines equipped with an oil pressure safety switch hold the fuel by-pass switch in the “start" position until the engine oil pressurereaches7 to 10psi [48 to 69 kPa]; then, move it to the “run” position.
2. Set the throttle for idle speed and disengage thedriven unit.
Caution: Protect the turbocharger during start-up by not opening the throttle or accelerating above 1000 rpm until the idle speed oil pressure registers on the gauge.
- Open the manual fuel shut-down valve,if soequipped.Fig.1-5.Electric shut-down valves operate as the switch is turned on. A manual override knob provided on the forward end of the electric shut-down valve allows the valve to be opened in case of an electric power failure. To use, turn fully clockwise; return it to the run position after an electric repair.
- Pull the compression release(if soequipped) and press the starter button or turn the switch- key to the “start” position. After three or four seconds of cranking, close the compression release (if so equipped) and continue to crank until the engine fires.
Caution: To prevent permanent cranking motor damage, do not crank the engine for more than 30 seconds continuously. If the engine does not fire within the first 30 seconds wait one to two minutes before re-cranking.
- At the initial start or after oil or filter changes andafter the engine has run for a few minutes shut it down and wait 15 minutes for the oil to drain back into the pan. Check the engine oil level again; add oil as necessary to bring the oil level to the “H” mark on the dipstick. The drop in oil level is due to absorption by the oil filters. Never operate the engine with the oil level below the low level mark or above the high level mark.
