Jerry, you have the electromechanical hydralic pump. Master off, pump. gear doors open. Master on gear doors close. In earlier planes with mechanical hydraulic pumps


" OPERATION OF LANDING GEAR DOORS (AIRPLANE ON GROUND).
For inspection purposes, the landing gear doors may be opened and
closed while the airplane is on the ground with the engine stopped. Operate
the doors with the landing gear handle in the "down-neutral" position.
To open the doors, turn off the master switch and operate the hand pump
until the doors open. To close the doors, turn the master switch on and
operate the hand pump.
NOTE
The position of the master switch for gear door operation
is easily remembered by the following rule:
OPEN circuit = OPEN doors
CLOSED circuit = CLOSED doors
