ENGINE
CONTROLS
The engine controls are centrally located, between the pilotand cc-pilot, on
the engine control console The throttle knob regulates manifold pressure.
Pushing the knob forward increases the setting; pulling the knob
aft
decreases the setting.
The propeller control, with its crowned blue
knob, controls engine RPM
through the propeller governor. Pushing
the
knob forward increases engine
RPM; pulling the knob aft decreases RPM.
The mixture control, with its red
flcrled knob, establishes the fuel-air ratio (mix-
ture). Pushing the knob full folward sets the mixture to full-rich, pulling the
knob aft leans the mixture, and
pulling the knob to its maximum aft travel
position closes the idle cutoff valve, shutting down the engine. Precise mix-
ture settings can be established by observing the EGT gauge on the pilot's
right hand instrument panel while adjusting the mixture control.
The propeller and mixture controls are vernier type and fine adjustments can
be made by turning the knobs clockwise or counter-clockwise. The vernier
controls should not be turned closer
than
118"
to the panel nut face. The
thrc)ltle has an integral friction device.
The cowl flaps are electrically actuated and may be positioned in any location
from FULL
OPEN
to FULL CLOSED in order to maintain oil and cylinder head
temperatures within their normal operating ranges. This may be ac-
complished by placing the cowl flap switch, located under the mixture con-
trol, in the
UP
or DOWN position. Observe the position indicator, located on
center console below the flap switch, until the desired position is obtained
-
and then return the switch to the
CENTER
or OFF position.
