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 three 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

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

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.
It is important that any time the pump runs for more than three minutes

OIL LEVEL
The oil level should be checked when the vehicle is first
purchased and then once every two years. More often if
there is an oil leak in the system.
All jacks and any HWH room extension cylinders should be
completely retracted before checking the oil level. The oil
reservoir is part of the pump/manifold assembly. The oil level
Most breather caps have a dipstick.
NOTE: Overfilling the tank can cause leakage of oil
through the breather cap.
ELECTRICAL SYSTEM
The batteries should be in good condition and fully charged.
Weak batteries can cause erratic operation. Battery cable
terminals and battery posts and connections should be kept
All electrical connections, especially ground connections,
should be clean, tight, free from corrosion and protected
JACKS
There are very few user serviceable parts on the jacks
The jacks require very little maintenance. If the jacks are
VISUAL INSPECTION
Periodically inspect the system for oil leaks and
damaged or missing parts, such as pivot bolts or springs.
Check the hydraulic lines and wiring for damage and wear.
Check that the jacks do not interfere with any parts of the
vehicle when they are in the "STORE" position.
The system will operate better if kept clean and free
from caked on mud or ice.
OPERATIONAL CHECK
Check that all lights work according to the "INDICATOR
LIGHT" Section. Correct function of the red "WARNING"
Review the OPERATOR MANUAL. Run the system
according to the SYSTEM OPERATION Section.
Note any abnormal operation.

Any visible mechanism can be kept clean by washing
with water. Refer to the vehicle manufacturer for
correct maintenance of the room seals.

The following is a list of problems, and possible solutions, which might occur to the leveling system.

MANUAL LEVELING SYSTEMS
A MASTER WARNING INDICATOR SHOULD ALWAYS BE USED. WHEN THE LEVELING SYSTEM HAS STRAIGHT-
ACTING JACKS A WARNING BUZZER MUST BE USED.
WHEN ONLY A RED MASTER WARNING LIGHT IS USED THE 12+ POWER FOR THE LIGHT COMES THROUGH THE
CONTROL PANEL. (SEE FIGURE 1 BELOW.) WHEN BOTH A RED LIGHT AND WARNING BUZZER ARE USED THE
+12 POWER FOR BOTH INDICATORS IS SUPPLIED BY THE IGNITION SWITCH. THE POWER MUST COME FROM
THE "ON" SIDE OF THE IGNITION SWITCH, NOT THE "ACC" SIDE. (SEE FIGURE 2 BELOW)
BY SUPPLYING IGNITION POWER TO THE WARNING BUZZER AND LIGHT, AND "ACC" POWER TO THE CONTROL
PANEL, THE SYSTEM MAY BE OPERATED IN ACCESSORY WITHOUT THE BUZZER SOUNDING. THE NEGATIVE SIGNAL
FOR THE WARNING INDICATORS MUST ALWAYS COME FROM THE CONTROL PANEL.
CAUTION: THE PURPLE WIRE IN THE MASTER WARNING LIGHT HARNESS IS HOT WHENEVER THE IGNITION
