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 keypad 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 maximum of 60 seconds. You may stop the ALL
RETRACT by pressing any button on the keypad. Your coach is equipped with air
suspension, and it is recommended that you start your coach before pressing ALL
RETRACT allowing the chassis air to build. This will ensure adequate air supply
to the chassis air valves.
Hydraulic Control Panel
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. Simply stated, 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 incor -
rectly senses excessive slope, this can be overcome by re-setting
the baseline zero point.
This will allow manual extension of all
jacks . Remember to re-set the baseline zero point after manu-
ally leveling the coach.
