Section III - SYSTEMS DESCRIPTION
RESETTING THE MAIN SYSTEM
Following use of the auxiliary system, the main system must be reset before normal operation of the
landing gear.
NOTES:
1. With the main system pressurized normally, the setting of the AUX HYD SYSTEM PULL
control lever has no effect on flaps operation.
2. If a selection is made to demonstrate or exercise the auxiliary system, operation of the
flaps will be from the main system.
To reset the system, first make sure the LANDING GEAR selector lever is in the down position, then
push the AUX HYD SYSTEM PULL lever fully in. This action opens the on/off valve to vent fluid
pressure in the auxiliary system lines to the return. The shuttle valves move back to connect the main
system to the down side of the gear jacks.
With the on/off valve open the check valve prevents normal pressure from the main system return line
draining the auxiliary reservoir and the baulk is repositioned by the spring unit to prevent movement of
the hand pump socket.
