f. Propellers - CHECK feathering to 1200 RPM; return to high RPM
(Full Forward Position).
,...------/CAUTION\ - - - - - . . . ,
During propeller feathering checks, do not allow the
propeller RPM to fall below 1000 RPM as this may
damage the hub mechanism.
g. Engine Instruments - CHECK green arc.
h. Throttles - 1000 RPM.
r--------NOTE-------__.
It is important that the engine oil temperature be
within the normal operating range prior to applying
takeoff power. Even cautious power applications
with cool oil may result in momentarily exceeding
the 39.0 inches Hg. manifold pressure limit. Refer
to Section 7 if momentary overboost of manifold
pressure occurs.
Fuel Quantity - CHECK.
Fuel Selectors - RECHECK - Left Engine - LEFT MAIN (Feel For
Detent) .

Full throttle checks on the ground are not recommended unless there is
good reason to suspect that the engines are not operating properly. Do not
runup the engines over loose gravel or cinders because of possible stone
damage or abrasion to the propeller tips.
If the ignition system produces an engine speed drop in excess of 150
RPM. or if the drop in RPM between the left and right magneto differs by
more than 50 RPM, continue warm-up a minute or two longer before rechecking
the system. If there is doubt concerning operation of the ignition system,
checks at higher engine speed will usually confirm if a deficiency exists.
In general. a drop in excess of 150 RPM is not considered acceptable.
