Reduce power to maintain limits.
During cold weather operations, 150 psig engine oil
pressure is permitted following engine start. When the
130 psig limit is exceeded, operate engine at idle RPM
until normal engine oil pressure is obtained. When
engine oil pressure is within normal limits, engine
may be operated within full range of temperature lim-
its (-54 to 107°C) without regard to engine oil tem-
