Manual Operation using the Equalizer Systems Auto-Level keypad
Power on: Push and release the Power keypad button to engage power. All lights should come on then most
will go out. The LED light next to the Power button should be lit RED when power is on. If you attempt to extend
jacks by pressing the Down keypad buttons or all the jacks with the Auto-Level button, you will hear a “deny”
tone from the keypad if the ignition key is in the improper position or the park brake needs to be set and if
equipped the LED lights for these will be on (see section below on panelLED’s)
Planting the jacks: Using the Down keypad buttons, extend the jacks until they contact the ground (this is
referred to as “planting” the jacks). As you extend the jacks, an LED light on the keypad will indicate the jack(s)
out of the “stowed” position. jacks may be operated individually or in pairs depending on the system supplied.
Do not manually overextend individual jacks. This may cause unwanted stress on the coach or the jacks.
Leveling the coach: Use a bubble level on a flat surface in the center of the coach. Level the vehicle by using
the Down or Up keypad buttons until the vehicle is level. Jacks may be operated individually or in pairs
depending on the system supplied as long as they are operated in the same direction. Do not attempt to lift the
vehicle’s tires off the ground. The keypad may be left on once level has been achieved. The keypad will enter
“sleep mode” after five minutes of inactivity.
Note: There maybe specific instances when manual extension of one or more jacks may inhibited (deny tone
when Down is depressed). This situation is caused by the ‘anti-twist’ protocol in the software installed in the
controller. 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 the other jacks to
overcome the slope. If the system incorrectly senses excessive slope, this can be overcome by re-setting the null.
This will allow manual extension of all jacks.
Retracting the jacks: Use the All Retract button to retract the jacks prior to travel.
The Equalizer System does provide the ability to retract the jacks using the UP buttons for jacks. However, these
buttons are not intended to be used for retracting the jacks to their stowed position prior to travel. The Up arrows
are to be used only for retracting the jacks to help level the coach. The All Retract button must be pressed to
insure the system is ready/safe for travel. All jacks (rear only) will automatically retract and return to stowed
position when the ALL RETRACT button is pressed and released. Tthe front jacks will need to be retracted using
the UP arrow(s) to the stowed position after coupling to the tow vehicle. When All retract is pressed the pump
will run in retract for approximately 5 seconds after the last (rear jack) jack has been fully retracted- or until a
time limit of 90 seconds has been reached.
*It is always the responsibility of the coach operator to visually confirm that the jacks
are fully retracted and safe for travel*
Dual Leg Switch and Harness
Your system includes a dual leg switch and harness that allows the independent operation of the front jack legs.
This is primarily so that the front legs can be extended to lift and support the trailer from the tow vehicle. This
dual leg switch control includes a key switch to disconnect it so that unauthorized operation of the front jacks can
be avoided. During travel this key switch must be turned to the off position and the key removed. To operate
insert the key turn it to the on position then the rocker switches can be used to operate the front jacks
independently or as a pair up or down. Do not attempt to operate jacks in opposite directions at the same time.

Operation

Auto-Level Operation
Power on: Push and release the Power keypad button to engage power. All lights should come on then most
will go out. The LED light next to the Power button should be lit RED when power is on. Other lights should go
out, if they do not refer to the keypad LED section. If the jacks down lights are on they must be cleared by
pressing the all retract button prior to performing Auto-Level.
Front Jacks: It is required that tow vehicle be disconnected from the trailer prior to leveling with Auto-Level.
Use the down arrow(s) on the control panel (or use the dual leg switch) to extend the front jacks to support the
trailer and lift the trailer from the tow vehicle. After the tow vehicle is removed, lower the front of the trailer so
that the trailer is level front to rear (visually level). Generally, it will work best if the front is slightly lower that
the rear. This is somewhat a trial and error/learning as all trailer units seem be slightly different.
Auto-Level: Press the Auto-Level button and release. The system will send out a continuous series of beeps and
the “Operating” LED will flash RED to let you know Auto-Level is operation the rear legs will be deployed and
then the system will use the front and the rear legs to automatically level the coach. When completed, the keypad
will signal the successful completion with a dual-stage tone. The keypad may be left on once level has been
achieved. The keypad will enter “sleep mode” after five minutes of inactivity. If the unit is not level after the
process is complete see the section on setting the Null.
Retracting the Jacks: Use the ALL RETRACT button to retract the jacks prior to travel
The Equalizer System does provide the ability to retract the jacks using the UP buttons for jacks. However, these
buttons are not intended to be used for retracting the jacks to their stowed position prior to travel. The Up arrows
are to be used only for retracting the jacks to help level the coach. The All Retract button must be pressed to
insure the system is ready/safe for travel. All jacks (rear only) will automatically retract and return to stowed
position when the ALL RETRACT button is pressed and released. The front jacks will need to be retracted using
the UP arrow(s) to the stowed position after coupling to the tow vehicle. When All retract is pressed the pump
will run in retract for approximately 5 seconds after the last (rear jack) jack has been fully retracted- or until a
time limit of 90 seconds has been reached.
*It is always the responsibility of the coach operator to visually confirm that the
jacks are fully retracted and safe for travel*
If the coach is not level following an attempt to Auto-Level, you will need to level the coach and reset the null. To
set the null, push and release the Power button on the Keypad to engage power. The LED light next to the Power
button should be lit RED when the power is on. Level the coach by deploying jacks manually, or by simply
parking the coach on a level site. You do not need to have the jacks deployed to set the null. Use a bubble level on
a flat surface in the center of the coach as a reference. Once the coach is level, turn the power off at the panel.
Depress and hold the Auto-Level button and press and release the Power button and listen for a series of beep.
After the Keypad has beeped 5 to 6 times, release the Auto-Level button (the Keypad will continue to beep as
long as the Auto-Level button is held). You should receive 2 beeps indicating that the new Null has been set the
panel will maintain this setting. Press and release the All Retract button to retract the jacks to the stowed position.
Do not allow excessive motion in the unit during the Auto-Level operation (don’t move around in the unit).
This could cause the system to level improperly.
The Auto-Level 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 procedure for proper operationof
this option. It is usually better to review this procedure prior to its actual use, rather than having to learn a
new procedure in difficult environments.
If the system has not been used (with the jacks stowed) for over 24 hours, it is recommended that youengage
the All Retract button prior to travel in order to re-pressurize the system.
A lubricant, like WD40, may be used to clean and lubricate the cylindershafts.

Setting the Null: Null is the term used to indicate the levelness of the coach
Helpful Hints

There are a total of ten (10) LED indicators on the Equalizer Keypad. The function of
these LED's is detailed below.
During typical operation, the LED's on the bottom left hand corner of the keypad should NOT be
illuminated. The only LED that should light is the “OPERATING' LED, which should flash during
operation.
'POWER’ LED...................................................ON Red when power is ON
OFF when power is OFF
FLASH every 1 sec. In Sleep Mode
'JACK' LED (4 each) .................................... ON Red when jack(s) are deployed
OFF when jack(s) are stowed
'OPERATING' LED ......................................FLASHING Red w/ Auto Level or All Retract
OFF when keypad is idle or 'sleeping'
'LOW VOLTAGE' LED ................................ON Red when voltage is below 10.5 VDC
OFF when voltage is above 10.5 VDC
'ENGAGE PARK BRAKE' LED ...................ON Red when park brake is not set
May not be present onnewer trailer OFF when park brake is set.
version units -See Step 9 (installation)
'IGNITION ON' LED ....................................ON Red when ignition is in the ON position
May not be present onnewer trailer OFF when ignition is off
version units- See Step 8 (installation)
'EXCESS SLOPE' LED .................................ON Red following an Auto-Level attempt if
system cannot overcome slope
OFF when slope is not excessive
If the LOW VOLTAGE, ENGAGE PARK BRAKE, IGNITION ON or EXCESS SLOPELED's
illuminate, you have an 'error' condition that must be corrected prior to operating thejacks.
If the jacks down status lights are on (rear lights on trailer version) AutoLevel will be denied.Press
the all retract to clear.

Panel Indicator LED's

Your hydraulic motor is equipped with a manual override output shaft. You must use a drill with
a 7/16" socket driver.
The drill must be capable of producing a minimum of 2000 r.p.m. for the pump to develop
appropriate pressure output.
Care must be taken to ensure neither the drill nor the socket contact any wires or hydraulichoses
while in use.
END VIEW OF MOTOR
To operate your jack(s) using the manual override
The individual cartridge valves are clustered together on the side of the pump manifold. Theyare
labeled 1 thru 4. Locate the screws on the appropriate cartridge valve(s). Using a small flat blade
screwdriver or 1/8” Allen wrench,(depending on valve type) turn the screw(s) clockwise until
seated in.
Remove the black plastic cap from the end of the motor. Use a small flat head screwdriver.Place
the drill with the 7/16" socket on the manual override shaft located at the end of the motor.
To retract your jack(s) run the drill in the counter-clockwisedirection.
To extend your jack(s), run the drill in the clockwise direction.
When manual override is complete, return the cartridge valve(s) to the normal position(s).
Reinstall black plastic cap on motor.
Caution: Following manual override operation, failure to return all valves to normal position may result
in one or more jack legs drifting down from their retracted (stowed) position. For cartridge valves, rotate
the center screw fully counter-clockwise.
*Note* The normal operating position of the screw in the cartridge valve is the counter-clockwise 'out'
position. The only time the valve should be shifted manually is when attempting to operate jack(s) via
manual override.
