AUTOMATIC JACK RETRACTION
Start the engine and press the “Auto Store” button. The
store indicator light will flash. The vehicle should start to
return to proper ride height. The front jacks will retract for
5 seconds before the rear jacks will begin to retract. As
each jack retracts, its red “Warning” light will go out. The
system will automatically shut down 1 minute after the four
individual red “Warning” lights are out.
The vehicle can be moved as soon as the red warning
lights are out, the jacks are in the Store/Travel position
and the green “Travel” light is on, if the vehicle is at the
proper ride height for traveling.
Do not move the vehicle while the leveling jacks
are still in contact with the ground or in the extend
position. This vehicle is equipped with straight-
acting jacks. Moving the vehicle with the leveling
jacks extended can cause severe damage to the
jacks and/or the vehicle and create a driving hazard.
Do not rely solely upon warning lights. It is the
operator’s responsibility to check that all jacks are
fully retracted into the store/travel position and the
vehicle is at the proper ride height for traveling.
WARNING
!
If a red warning light and buzzer come on while
traveling, the jacks should be checked as soon as a
safe parking location is found.
IMPORTANT
! Manual Hydraulic Operation
Place transmission in the recommended position for
parking the vehicle, and set the parking brake. Turn the
ignition to the “Accessory” position.
Place pads under the jack feet if the ground will not
support the vehicle on the jacks.
Push the “Dump” button. Wait until all air is exhausted
from the vehicle suspension.
The vehicle may be leveled using the manual Extend (up
arrow) buttons on the right half of the panel. If a yellow
Level Sensing light is on, that side, end or corner of the
vehicle is low. It is best to level the vehicle side to side
first, if needed, before front to rear.
When leveling is completed, turn the ignition switch to the
“O ff ” position.

Jacks will extend (or retract) in pairs to raise (or
lower) a side or end of the vehicle. Any jack not
used for leveling can be extended to the ground.
This provides additional stability against wind and
activity in the vehicle. Jacks used to stabilize the
vehicle after leveling is complete should lift the
vehicle slightly after touching the ground.
NOTICE
!
Do not continue to push an Extend button for more
than ten (10) seconds after that pair of jacks are fully
extended.
IMPORTANT
!
Fluid Level Maintenance
The hydraulic leveling system was filled with Dexron/
Mercon transmission fluid during production. Periodically
check the fluid levels in the leveling system when using
the breather cap/dipstick. Remove any debris from
the dipstick before reinserting it into the reservoir. The
reservoir level should remain between the oil level
grooves when the jacks are retracted. Add fluid as
needed. Change the fluid if it becomes contaminated.
HWH Hydraulic System Troubleshooting Tips
PROBLEM
This article provides troubleshooting tips for the
following components:
•
HWH hydraulic slideouts
•
HWH hydraulic generator slideouts
•
HWH hydraulic entrance steps
•
HWH hydraulic leveling jacks
If any, or all, of these HWH hydraulic components are
not functioning, follow the troubleshooting steps before
contacting Newmar or HWH.
SOLUTION
If the pump runs for an accumulative time of
approximately three minutes while operating the HWH
jacks, slideout(s), generator slideout, or the step, the
system will turn o ff and the pump will stop running. This
only applies to coaches equipped with an HWH step.
If for some reason the pump doesn’t run for any HWH
equipment, it might be necessary to reset the HWH
system. If this time lockout occurs, power for the HWH
control system must be removed before any system
components will function.
