Section 4: Vehicle Operation
Manual Operation
Power on
: Push and release the POWER keypad button to engage power. The LED next to
the POWER button should be RED when power is on. If you attempt to extend individual
jacks by pressing the DOWN keypad button or all jacks with the AUTO-LEVEL button, you
will hear a “deny” tone from the keypad.

Planting the Jacks: Using the DOWN keypad button, extend each jack until they
contact the ground (this is referred to as “planting” the jacks).

As you extend the jacks, the LED lights on the keypad will indicate the jacks are
out of the “stowed” position. Jacks may be operated individually or in pairs.
 Do not manually overextend individual jacks. This may cause unwanted
stress on the coach or the jacks.

Leveling the Coach: Use a bubble level
in the center of the coach as a reference.
Level the vehicle by using DOWN or UP
keypad buttons until the vehicle is level.
Jacks may be operated individually or in
pairs as long as they are operated in the
same direction.
 Do not attempt to lift the vehicle off of
the tires. The keypad may be left “on”
once level has been achieved. The key-
pad will enter “sleep mode” after five
minutes of inactivity.

Retracting the Jacks: The Equalizer System provides the ability to retract the
jacks using the ALL RETRACT button or the UP button for each individual jack.
All jacks will automatically retract and return to stowed position when the ALL
RETRACT button is pressed and released. The pump will run in retract mode
until all of the jacks are fully stowed (plus an additional 5 seconds) up to a maxi-
mum of 60 seconds. You may stop the ALL RETRACT by pressing any button on
the keypad.
™
NOTE: Your coach is equipped with air suspension, and it is recommended
that you start your coach
before
pressing ALL RETRACT allowing the chas-
sis air to build. This will ensure adequate air supply to the chassis air valves.
™
NOTE: There are specific instances when manual extension of one (or more)
jack is inhibited (deny tone when DOWN is depressed). This situation is
caused by the “anti-twist” protocol in the software contained in the control
box. The “anti-twist” protocol denies jack extension if the system senses that
a specific corner of the coach is approximately 3 degrees higher than the rest.
You will be able to extend other jacks to overcome this slope. If the system
incorrectly senses excessive slope, this can be overcome by re-setting the base-
line zero point.
This will allow manual extension of all jacks
.
Remember to
re-set the baseline zero point after manually leveling the coach.
Helpful Hints

Your leveling system is a microprocessor-controlled system. Proper and adequate
battery voltage and permanent chassis ground are essential.

Your system may be equipped with a manual override option. Refer to the proce-
dure for proper operation of this option. It is better to review this procedure prior
to its actual use.

If a jack comes out of the stowed position while traveling, the system panel will
automatically activate and return the jack to the stowed position.
