.
-Check:
.All warning and caution lights off.
.Electrical system voltage and current.
.Engine oil pressure.
-Switch on/engage all necessary systems (VHF, lights,
windshield wiper*, etc)
~ : Do not use the wiper on a dry windshield or in light rain.
-Carry out a hydraulic accumulator test:
.Check: collective pitch -locked.
.Cut off hydraulic pressure by actuating the test
push-button On console
~
.Check that the HYDR light illuminates and sounds GONG
.Move the cyclic stick 2 or 3 times along both axes
separately on ~10 % of total travel, check for hydraulic assistance by
absence of control load. .
.Press the test push-button to restore hy~raulic
pressure ~ ---On console
Check that HYDR light goes out.
-Carry out a hydraulic pressure isolation check:
.Isolate hydraulic pressure by actuating the switch on the
collective pitch lever: the HYDR light illuminates and
control load is felt immediately, except on yaw pedals, where
control load should remain low because of load-compensating
servo.
.Restore hydraulic pressure using the switch: the HYD light goes out
after 2 to 3 s.
~ : In strong wind, apply a little forward cyclic.
NOTE 2 : If the starting cycle has to be aborted, return the start switch
to the closed position, and switch off the fuel pump and the
generator.
