q. PRIMARY ROTARY PUMP.
The primary rotary pump is located in the APU compartment underneath the APU on the lower right-hand side as you face
the outside of the vehicle. The primary rotary pump is activated by the APU when the check valve located near the inflating-
deflating pump is in the IN position. The primary rotary pump is powered by a direct drive from the APU and provides
hydraulic pressure to the hydraulic actuator and to the hydraulic motor.
