The auxiliary hand pump is a two stage pump that
will produce enough pressure to lift the room. When
lift the trailer as well as retract the landing gear. When
operating the auxiliary pump to lift the room, the pump
handle will seem to "snap" as the pump goes to the
second stage. The pumping action will be easier at
first as the second stage starts to create more pressure.
To operate the auxiliary hand pump, move the hydraulic
switch to the desired position. Insert the hand pump
handle into the handle receptacle and move the handle
in an up and down motion.
It is recommended to operate the auxiliary hand
pump occasionally to check it’s operation.
