	HANDLING AND GENERAL MAINTENANCE INSTRUCTIONS

(10) Turn the fuel selector to "REAR WING". Never turn the valve pointer through "BELLY" when a belly tank is not installed.      (11) Operate the electric booster pump to obtain 12 to 16 ps.i. fuel pressure.      (12) Prime the engine one stroke and pull the primer pump handle "OUT".      (13) Turn the ignition switch to "BOTH".      (14) After the starter has been hand cranked up to speed, and the engine begins to turn over, prime with a slow steady stroke. When the engine "catches", move the mixture control to "'AUTO-RICH".       NOTES       Do not move the mixture control out of "IDLE CUT-OFF" while the starter is engaged. Do not operate the electric booster pump with the mixture control out of "IDLE CUT-OFF" when the engine is not firing.       WARNINGS       If the engine "quits" after starting return the mixture control to "IDLE CUT-OFF" immediately. If the oil pressure is not established within 15 seconds after starting, stop the engine and investigate the oil pressure failure.      (15) Close and lock the primer.    h. ENGINE WARM-UP.      (1) Start warming up the engine at 800 to 1000 rpm until the oil pressure sta'blizies at 60 to 70 psi. When the oil pressure no longer fluctuates and the temperature begins to rise, gradually increase to approximately 1,400 rpm. The minimum oil temperature for 1400 rpm or over, is 150C. (59'F.) If known icing conditions exist, move the carburetor air control to "HOT".      (2) During warm. up the oil pressure should not exceed 120 p.s.i. and the normal oil temperature should be 60°c to 80°C. (140°F. to 176°F.) with a maximum of 851°C. (185°F.)      (3) Fuel pressure for idling should be maintained at 9 psi. and for operating 17 pounds, ±1 pound.

(4) Avoid prolonged ground running of the engine.      (5) Adjust the cockpit heating and ventilator control as desired.      (6) Set the cowl flaps as the temperature requires.      (7) Set the carburetor heat control as required. Do not operate the engine with heat to the carburetor unless icing conditions prevail.      (8) In desert or sandy areas, be sure the filter control is in the "FILTERED" position.    4.
