BEFORE INSTALLATION AND OPERATION
Installer: Provide these instructions to the consumer.
Consumer: Keep documents for future reference.
Atwood Levelegs™ Levelers are intended for use on recreation vehicle
motorhomes and trailers, any other use is strictly prohibited.
WARNING
VEHICLE CAN MOVE OR COLLAPSE
• Never exceed the rated capacity of the leveler as stated on its label.
• Levelers are not designed to be used as jacks. Do not use levelers to
lift the vehicle during tire changes, axle work or other servicing. The
tires must stay on the ground.
INSTALLATION
LEVELER LEG
1. Prior to installation, retract the levelers so the foot pads are within
1/2˝ to 1˝ from the end of the outer housing (FIG 1-A).
2. Position leveler vertically against frame so base of foot has 8-9˝
minimum ground clearance when vehicle is loaded to its maximum
GVWR (FIG 1-B).
3. A. For 7.5K Square Tube Levelegs™, attach the frame bracket (
to frame (FIG 12-D) using 4 sets of 1/2˝ - 13 grade 5 nuts and bolts
and 1/2˝ flat and locking washers. Fit the Leveleg bracket (FIG 12-E)
around the Leveleg, (
bracket (FIG 12-G) and the other tab below the bracket (FIG 12-H).
Attach the Leveleg bracket to the frame bracket with a 1/2˝ - 13
grade 5 bolt and 1/2˝ flat washer on the Leveleg bracket and a 1/2˝
flat washer, 1/2˝ locking washer and 1/2˝ - 13 grade 5 nut. To install
on 5th wheel trailers, refer to MPD 71125.
B. For 10K Square Tube Levelegs™, attach the leveler bracket (
to the frame bracket (FIG 13-C) using four (4) each 1/2˝-13 grade 8
bolts and 1/2˝ flat hardened washers.
C. For 15K Square Tube Levelegs™, attach the leveler bracket (
the frame bracket (FIG 14-C) using six (6) each 1/2˝-13 grade 8
bolts and 1/2˝ flat hardened washers.

OPERATION
BEFORE OPERATING THE LEVELERS
CAUTION
PERSONAL INJURY
• Stand clear of the vehicle.
Before operating the levelers, you must do the following:
1. Park the vehicle on a level site. Check for rocks, holes, or other
obstructions. Warn all persons to stand clear of vehicle.
2. For a motorhome,
• Put the vehicle transmission in
• Engage the vehicle PARKING BRAKE.
• Have the vehicle engine running.
3. Do not extend the slideouts until coach is level.
PARK.
WARNING
VEHICLE CAN TIP
Levelers must be on firm solid ground or surface prior to operation.
•
Soft/spongy ground may allow levelers to sink.
• Area below and around leveler must be clear of obstructions.
• Do not place blocks under the leveler for additional ground clearance.
LEVELERS ARE SHIPPED IN THE ERROR MODE STATE.
To take controls out of error mode state, complete a successful
ALL RETRACT (as defined in items 1-3) under TO RETRACT.
4. Put stripped yellow (+) wire end into contact pin (
crimp together. Crimp must withstand a minimum pull of 75 lbs.
5. Put stripped red (-) wire end into contact socket (FIG 15-R2) and
crimp together. Crimp must withstand a minimum pull of 75 lbs.
6. Insert the contact pin (

AUTO POSITION CONTROLS
Your keypad may have LEDs to indicate ‘EXTEND’ OR ‘RETRACT’ mode.
If the Auto position is already set or programmed,
• Press the ON button (
• Press the AUTO button (FIG 9-B).
• The levelers will extend and automatically reach the pre-set position.
• The system will check each Leveler to insure its foot is in contact
with ground. During this time, the control board “WAIT” LED will be

TO SET AUTO POSITION
1. Look at the keypad for your system. You have an automatic controller
if there is a button that says “AUTO” (FIG 9-B).
2. To set the AUTO position
a. Manually get the RV to the position you want.
b. Then press the ON (
c. Press ‘EXT’ button (FIG 9-D) 5 times.
d. Press ‘RET’ button (
e. Unit will respond by blinking all LEDS slowly.
f. Press ‘ALL’ button (FIG 9-F) 3 times.
g. Press ‘ON’ (FIG 9-A) then ‘RET’ ‘All’ to retract all Levelegs (FIG 9-E
and 9-F).
TO SET AIR DUMP MODE
1. If LEDs blink left-to-right and back again, your RV has the Air
Dump feature.
a. To enable Air Dump, press the “DRIVER” button
(3) times. The driver side LEDs (FIG 9-H) will illuminate for 3 seconds and shut off. Press “ON” (9-A), then “RET” “All” to retract
all Levelegs (
b. To disable Air Dump, press the “PASSENGER” button (FIG 9-I)
three (3) times. The passenger side LEDs (FIG 9-J) will illuminate
for 3 seconds and shut off. Press “ON” (FIG 9-A), then “RET”
“All” to retract all Levelegs (
c. If the Air Dump feature is not set or has never been configured,
the system will wait for 30 seconds. It will default to “Not
Configured” and the passenger side LEDs will illuminate for
3 seconds and shut off.
2. To change Air Dump from enabled to disabled or vice versa, have
the engine running, the park brake engaged and the transmission in
PARK.
a. Press “ON”
b. Press the “EXT” button (FIG 9-D) ten (10) times.
c. Press the “RET” button (FIG 9-E) ten (10) times.
d. The LEDs will blink left-to-right and back again. Go up to step
3 above and follow the directions to either enable (step 3-a) or
disable (step 3-b) the Air Dump feature.
e. To check the status of the Air Dump, wait 30 seconds and see
which LEDs illuminate. If the air dump is enabled, the driver
side LEDs

TO MANUALLY DUMP THE AIR BAGS
a. Engine must be running.
b. Transmission must be OUT of Park/Neutral.
c. Parking brake must NOT be engaged.
d. Atwood Levelegs keypad is NOT on. Lights inside the ON switch
are not lit.
e. Press the FRONT + REAR + ALL buttons to dump air from air
bags. (Note: Air dump feature does need to be enabled for this
feature to work.)
f. Air bags dump in approximately 20 seconds and air bags refill
60 seconds from the start of the air dump.
These controls have the following features to facilitate leveling:
• TO MAXIMIZE AVAILABLE LEVELER STROKE During the initial activation of a
pair of levelers following the
onds the first pair of levelers extend, the opposite pair of levelers will
retract for two (2) seconds. This process will repeat for the first 60 continuous seconds of extension of first pair of levelers.
• FULL EXTENSION If a leveler is fully extended, its corresponding LED will
indicate this and further operation of that pair of levelers in the extend
direction is prevented. If the switch is held on, the second leveler of the
pair will operate with its alternate pair partner leveler. (i.e., if the front
two levelers are extending and the left front leveler becomes fully
extended, the right front leveler will continue to operate and the right
rear leveler will start to extend.) This is to keep the frame from twisting.
• LOAD COMPENSATION If one leveler becomes disproportionally more
loaded than its pair partner, power will shut off to the first leveler. The
second leveler will continue to operate until the load is more balanced
between the pair of levelers. Power to the first leveler will then resume.

TO RETRACT
1. Ensure slideout rooms are fully retracted (in their inboard position).
2. Press the
3. Press the ALL button (FIG 9-F) and RETRACT button (FIG 9-E) simultaneously and release. Levelers will retract automatically to their fully
retracted position. The leveler indicator LEDs will blink red (FIG 9-H
or 9-J) during this activity.
4. Once levelers are fully retracted, level indicator LED (FIG 9-H) will be
solid green.
NOTE: After operating levelers, the position LEDS for all the levelers must be

solid green before the vehicle is to be moved. A visual examination of
all the levelers outside the motor home is recommended to insure
levelers are fully retracted.
CAUTION
PRODUCT DAMAGE
• Do not move vehicle until levelers and landing legs are fully retracted.
• Damage can occur to levelers, coach and surrounding property if the
levelers are not fully retracted prior to vehicle being moved.

SYSTEM PROTECTION FEATURES
Automatic Retract
• Anytime the engine is on, if the vehicle brake is depressed and
transmission is taken out of park, the levelers will fully retract
automatically.
• During auto retraction, an alarm will sound and all LEDs will blink on
and off.
Nine Cycle Maximum
• The controls will shut off for 15 minutes any time nine (9) full
retractions occur in less than 30 minutes.
• When this occurs, all four system status lights blink off and on.
• This sequence can be over ruled by turning the ignition off, then back on.
Low Voltage Protection
• If the voltage falls below 10.5 VDC, leveler operation will cease
and the low voltage LED will flash.
Controls will be inoperable until battery voltage climbs above 13
•
VDC, at which time leveling functions will resume.
Manual Override
• To Manually Extend or Retract Leveler, use a 1/2˝ socket on Drive
Nut on the end of the motor (FIG 10-A).
Rotate nut counter clockwise (looking from bottom end of nut
FIG 10-B]) to extend leveler.
[
NOTE: It takes 500 revolutions of nut to extend/retract leveler 1˝.
