(1) Maximum permissible sustained torque is 1315 ft/lbs. Propeller speeds (N2) must be set so at not to exceed power limitation. (2) When gas generator speeds are above 72% N1 and oil temperatures are between 60 C and 70 C, normal oil pressures is between 80 and 100 psi. Oil pressure between 40 and 80 psi is undesirable; it should be tolerated only for the completion of the flight, and then only at a reduced power setting. Oil pressure below 40 psi is unsafe; it requires that either the engine be shut down, or that a landing be made as soon as possible, using the minimum power required to sustain flight. (3) For increased service life of engine oil, an oil temperature of between 74 C and 80 C is recommended.

9 A minimum oil temperature of 55 C. is recommended for fuel heater operation at take off power. (4) These values are time limited to two seconds. (5) High ITT at ground idle may be corrected by reducing accessory load and/or increasing N1 RPM. (6) Cruise torque values vary with altitude and temperature. (7) Reverse power operation is limited to one minute. (8) Higher generator load at low N1 speeds may cause the ITT transient temperature limit to be exceeded. This does not apply during engine start. Observe generator load limits. PROPELLER BLADE AND HUB NUMBERS. Two full-feathering, constant-speed, reversing, four-bladed propellers consisting of D9510SK blades and HC-D4N-3C hubs.

ASYMMETRY MAY OCCUR IF REVERSE IS SELECTED. PROPELLER ROTATIONAL SPEED LIMITS. CAUTION. Stabilized ground operation between 400 and 1,100 RPM is prohibited. Operation between 0 and 400 RPM is permissible only with propeller feathered. WARNING. STABILIZED GROUND OPERATION WITHIN THE PROPELLER. RESTRICTED RPM RANGE CAN GENERATE HIGH PROPELLER.
