MBE 900 OPERATOR'S GUIDE NOTICE: Engine Oil and Filter Changing Correct torque on the high pressure lines is critical. Incorrect torques could result in leaks or lack of power due to restricted fuel flow. FIRE 11. Bleed the fuel system. To avoid injury from fire, keep open flames, sparks, electrical resistance heating elements, or other potential ignition sources away when draining lubrication oil. Do not smoke when draining lubricating oil. [a] Make sure that all high-pressure lines have been tightened to 25 N·m (18 lb·ft)) and all banjo bolts to 40 N·m (30 lb·ft). [b] If equipped with a hand pump on the fuel/water separator, work the hand pump 50 times. NOTE:
Select the SAE class (viscosity) on the basis of the average air temperature for the season. See Figure 43. View the temperature ranges for the various SAE classes as guidelines which can be exceeded for only a short time. [c] Crank the engine for 30 seconds at a time, but no longer. Before cranking the engine again, wait at least two minutes. The engine should start within four 30-second attempts. 12. Start the engine. Check the fuel filter for leaks.
