MAINTENANCE Air Bleeding Procedures IMPORTANT: Air in the fuel system may make the engine hard to start or make it run irregularly. After draining water and sediment from the water separator, replacing the fuel filter, cleaning the fuel solenoid pump strainer or running the fuel tank dry, be sure to bleed the air from the fuel system. 3 This machine is equipped with a fuel solenoid pump.

Turn the key switch ON and hold it in that position for ap- prox. 3 minutes. Thereby, the electrical fuel pump oper- ates, starting to bleed air. 3.
While holding the key switch in the ON position, recip- rocate fuel main filter priming pump (6). After air is bled from the main filter, return priming pump (6) to the origi- nal position. 4. After the main filter is filled with fuel, hold the key switch in the ON position for 30 seconds. M1GR-07-002 5. Start the engine. Check the fuel supply system for fuel leaks. CAUTION: Even if air is not thoroughly bled, do not hold the key switch in the ON position for more than 5 minutes. In case air is not thoroughly bled, first return the key switch to the OFF position. Then, after waiting for more than 30 seconds, turn the key switch ON again.
Failure to do so may cause damage to the electrical pump and/or discharging the batteries. 7-57
