ENGINE MAINTENANCE - Maintenance Procedures Fuel Blending Valve CAUTION CAUTION 1 2 Operate priming pump at a maximum rate of 30 strokes per minute to pre- vent damage to pump. If the engine is cranked excessively Starter Protection will be triggered and starter engagement will be restricted for 10 minutes. 2 4. Check for leakage at the fuel filtercap. Tighten if necessary. WARNING NOTE Check the fuel filter for signs of leak- age. Do not smoke or allow an open flame in close proximity. Failure to do so could ignite a fire or cause an ex- plosion which could result in serious injury to you and/or bystanders.
Fail- ure to comply may result in death, per- sonal injury, equipment or property damage. Allowing the engine to idle for several minutes with the fuel blending valve in the prime postition assists in purging air from the fuel system. Valve Position 1. Run 2. Prime 6. Check the system for leakage while idling. Then turn the engine off and check the system again for leakage. 7. If the engine does not start within this time, repeat steps two and three until the engine starts. If the engine still does not start, allow the starter to cool down for at least 5 minutes before repeating the procedure. 8. If equipped with a return fuel blending valve, turn the bypass to the RUN position. NOTE 5.
Start the engine and allow it to idle for several minutes. Note that it could take up to 15 seconds of cranking for the engine to start. If the starter is engaged for longer than 20 seconds without starting, additional priming pump actuation may be necessary. Failure to return the bypass to the RUN position will prevent fuel recircu- lation and heating. Y53-1166-1G1 (08/2018) 63
