PUMP RUN TIME
SYSTEM VARIATIONS FOR PUMP RUN TIME
Contact HWH corporation to get specific information about the system in this vehicle.
No matter what HWH system is on the vehicle, the pump should not be ran for more than four minutes
(3" motors) or six minutes (3.7" or 4.5" motors) without allowing the pump motor to cool for thirty minutes.
Continuous operation of the pump motor without allowing the motor to cool can damage the pump motor.
Some HWH systems are equipped with a lighted reset switch.
If the processor turns the pump off because the run time has
been exceeded, the light in the reset switch will turn on. The
With some systems, when the processor has turned the pump off because the run time has been exceeded, power
to the HWH system must be turned off and back on before the system will operate. With motorized vehicles, turn the
ignition off and back on. With non-motorized vehicles, turn the master power switch for the HWH system off and back

When operating some leveling systems manually or operating the room extensions, the pump will turn off and back

Some systems can be turned back on immediately after the processor turns the pump off.

pump motor to cool for thirty minutes.
The HWH systems with a computer processor monitor the pump run time and will turn the pump off if the run time exceeds a
specified time. This time can vary with different systems. Due to available electronics or system design, the pump run time
programs will also vary. Leveling systems and room extensions that are not controlled by a system processor have no pump
run time protection.

For cold weather information see "COLD WEATHER OPERATIONS" below.
COLD WEATHER OPERATIONS
HWH leveling and room extension systems are designed to function in cold weather down to 0 degrees Fahrenheit. Below
freezing (32 degrees Fahrenheit) the jacks or rooms will operate slower than usual.
For operation in temperatures dropping below -20 degrees Fahrenheit, it is necessary that the system is equipped with oil
designed for extreme cold weather application such as a synthetic oil. (Contact HWH for recommendations.)
DO NOT run the pump motor continuously.
Continuous operation of the pump with slow moving jacks or rooms in cold weather, without allowing the pump motor to
cool will cause the pump motor to burn up and damage the pump assembly.

WARNING: THE VEHICLE SHOULD BE
IMPORTANT: FOLLOW THE "SET UP" AND

WHEN USING THE AUXILIARY HAND PUMP.
AUXILIARY
HAND PUMP
HANDLE
The auxiliary hand pump is a two stage pump that will produce
enough pressure to extend the landing gear and lift the vehicle
as well as retract the landing gear. When operating the auxiliary
pump to lift the vehicle or when the jacks are fully retracted, 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, open the appropriate
solenoid valve. Insert the hand pump handle into the handle
receptacle and move the handle in an up and down motion.
The auxiliary hand pump may work easier if only one
valve is open at a time. Be careful to not twist the
vehicle if only one solenoid valve is open.
It is recommended to operate the auxiliary hand
pump occasionally to check it’s operation.
