AUXILIARYHAND PUMPHANDLE
The auxiliary hand pump is a two stage pump that will produceenough pressure to extend the landing gear and lift the vehicleas well as retract the landing gear. When operating the auxiliarypump to lift the vehicle or when the jacks are fully retracted, thepump handle will seem to "snap" as the pump goes to thesecond stage. The pumping action will be easier at first as thesecond stage starts to create more pressure.
To operate the auxiliary hand pump, open the appropriate solenoid valve. Insert the hand pump handle into the handlereceptacle and move the handle in an up and down motion.
The auxiliary hand pump may work easier if only onevalve is open at a time. Be careful to not twist thevehicle if only one solenoid valve is open.
It is recommended to operate the auxiliary handpump occasionally to check it’s operation.

MAINTENANCE
In general, to insure the smooth operation of the leveling system, it is a good idea to occasionally check the individual leveling units to prevent problems. This is especially true under the unusual conditions stated in the following:
If driving conditions are unusually muddy, the units maybecome caked or clogged with mud. This condition may hamper the proper operation of the leveling system. This problem may be prevented or remedied by cleaning off each leveling unit if they become excessively muddy.
In wet or icy weather leveling units may become encrusted with ice. This may cause the leveling system to function improperly. To eliminate this problem, periodically check the leveling units and break loose any ice which may be causing
