)
1.Verify that the EDP1 (6) (EDP2 (2) ) FAULT light
located on Hydraulic/Smoke Detection Control Panel
(204VE) (1) is illuminated (low pressure due to engine
not running).
2.Ensure that the quantity indicator pointer SYS 1 (SYS
2) in the Hydraulic Fluid Quantity Indicator (4), located
on the main instrument panel (right side) indicates
about "Full".
3.Start the ACMP 1 (ACMP 2), by setting the ACMP 1
(5) (ACMP 2 (3) ) switch to ON position.
4.Check that the EDP1 (6) (EDP2 (2) ) fault light is still
illuminated.
5.Manually rotate the propeller 1(2) counter clockwise
so that it performs half turn (looking the propeller from
the front of the aircraft).
6.Check that the EDP1 (6) (EDP2 (2) ) fault light
extinguishes (due to high pressure).
7.Switch off the ACMP 1 (ACMP 2), by setting the
ACMP 1 (5) (ACMP 2 (3) ) switch to OFF position.
