Starting the engine

Headset, Radio ....................................................................... ON if needed
Altimeter setting ........................................ Correlated with ATC information
Compass heading indication ............................................................ Verified
Strobe ..................................................................................................... ON
Fuel pump .............................................. ON, check Fuel pressure increase
Manual fuel injections .................................................................. As needed
Throttle .......... Monitor on MLI : START as required between 0% and 15 %
Rotor brake ......................................... Apply - check the light - lock forward
Mixture ................................................................................ Full rich forward
Ignitions, Magneto and Plasma ....................................... ON, check beeper
Area ..................................................................................................... Clear
Radio clearance if needed
Starter .............................................................................................. Activate
STARTER light ........... checked ON and back OFF when switch is released
After engine starts, reduce throttle to set engine speed to :
.............................................................................. Warm engine : idle
Check oil pressure light ........................... OFF within 30 seconds of starting
Collective ........................................................................... Down, friction on
Alternator ............................................................... ON, check ALT goes off
CLUTCH .................................. Engage and lock switch – check light is ON
Throttle ........................................... Adjust if necessary to avoid engine stall
Rotor and Engine indicators .................................................... Synchronized
CLUTCH light ........................................................................... Wait for OFF
Note 1: Manual fuel injections: raise the collective lever to approx. one third of
its stroke so that mechanical correlation allows large throttle strokes.
Then, roll the twist grip back and forth 2-3 times. This actuates the
carburetor mechanical acceleration pump and injects fuel in the inlet
manifold.
Note 2: Cold weather starting:
After a failed starting attempt, oil pressure red light may stay off a
while because of viscous cold oil. Pilot should crank again within 80
seconds of previous cranking. Otherwise, cranking will be inhibited
until oil pressure decreases in the red zone.
When starting an engine soaked at very cold temperature (-20 to
-10°C
throttle settings. Refer to SL10-001 for detailed recommendations.
Note 3: Depending on belt condition and temperature, the rotor may slightly
engage from engine start. In this case, engage clutch to avoid
prolonged belt slippage.
Note 4: As the rotor begins to spin, a cyclic stick rotation may occur. Center
the stick smoothly.
Note 5: ALT light may flicker at idle. Check ALT lights goes off above
1500 RPM.
