Atwood Levelegs™ Levelers are intended for use on recreational vehi-
cles, motorhomes and trailers.
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-F).
2. Position Leveler leg frame bracket (FIG 1-C & 4-C) vertically on frame
so that there is 8-9˝ minimum of ground clearance (4A-B) for a fully
retracted leg when the RV is loaded to its maximum GVWR. Leveler
legs may be mounted on inside or outside of frame and require cor-
responding Cross Brace Kit.
3. Weld frame bracket using two (2) 5/16˝ welds as shown (FIG 5-A).
Place leveler leg into mounting bracket with tabs up against bottom
edge of mounting strap (FIG 6-A) and bolt into place using 2 sets of
3/8˝ carriage bolts, 3/8˝ washers and 3/8˝ nuts (FIG 6-B). Torque both
bolts to 20 ft. lbs.
4. Repeat steps 1-3 for opposite leveler leg keeping the mounting positions
approximately the same distance behind axle.
5. Cross brace attachment - Attach top cross brace brackets (FIG 6-C) to
each jack under the tab on the jack using 3/8˝carriage bolts and 3/8˝
nuts and torque to 20 ft-lbs. Have top cross brace bracket openings fac-
ing opposite directions, one forward and one rearward. Attach each
cross brace tube to each attached bracket using the 5/16˝-18 bolts and
nuts (FIG 6-D). Do not tighten the bolts and nuts. Let the other ends of
the tubes rest on the foot of the opposite jack. Put 5/16˝-18 bolt through
center of cross brace tubes and put the nut on the bolt, but do not tight-
en. Place lower cross brace bracket (FIG 6-E) on jack facing the opposite
direction as the top cross brace bracket that is on the jack. Slide the
lower bracket up and attach the cross brace tube end (FIG 6-F) to the
cross brace bracket with 5/16-18 bolts and nuts. Put 3/8˝carriage bolts
and nuts on cross brace brackets and tighten to 20 ft-lbs. Insure lower
brackets do not prevent jack from fully retracting. Tighten all 5/16˝-18
nuts to 12 ft-lbs.

Hooking Up to Tow Vehicle to insure proper operation.
3. Check that the Activation Switch is in the OFF position (FIG 8-A).
This will keep the system from draining the battery.
OPERATION
CAUTION
PERSONAL INJURY
•Stand clear of the vehicle.
WARNING
VEHICLE CAN TIP
•Soft/spongy ground may allow levelers to sink. Levelers must be on
firm solid and resonably level ground or surface prior to operation.
•Insure area below and around leveler is clear of obstructions.
•Do not place blocks under the leveler for additional ground clearance.
Unhooking From Tow Vehicle and Leveling RV
1. Park RV on a reasonably level site with solid ground. Check for
rocks, holes or other obstructions at leveler positions. Chock RV
wheels and warn all persons to stand clear of RV and Tow Vehicle.
2. Do not extend the slideouts until RV is leveled.
3. Switch Activation Switch to ON (FIG 8-A)
4. Press ON to turn key pad on (FIG 8-B). LED will light ON button.
5. Press EXT/ALL/FRONT (FIG 8-J,G,C) to auto extend landing gear to
ground. LED’s for front levelers will be blinking green to indicate
landing gear is down.
6. Press and hold EXT/FRONT (FIG 8-J,C) or RET/FRONT (FIG 8-H,C) to
get King-pin/Gooseneck into preferred hitch detachment position.
7. Detach trailer lights, harness and hitch using manufacturer’s sug-
gested procedure. Move tow vehicle to safe position clear of RV.
8. Press AUTO (FIG 8-K) to extend rear levelers and auto-position RV.
Process will take 2-3 minutes and wait LED will be lit. All leveler
LED’s will blink green when process complete.
9. Press the ON (FIG 8-B) button to turn key pad off and switch the
Activation Switch OFF (FIG 8-A) to minimize battery usage.
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 ALL extend activation, for every six (6)
seconds 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 lev-
eler 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 bal-
anced between the pair of levelers. Power to the first leveler will then
resume.
Hooking Up to Tow Vehicle / Retraction of Levelers
1. Have all slideout rooms retracted (in their inboard position) and
warn all persons to stand clear of RV.
2. Switch Activation Switch to ON (FIG 8-A).
3. Press ON to turn key pad on (FIG 8-B). LED will light ON button.
4. Press RET/REAR (FIG 8-H,F) to auto retract the rear levelers. LED’s
for rear levelers will go to solid green to indicate levelers are fully
retracted. A quick visual inspection should be done to check leveler
ground clearance is proper for safe towing.
5. Press and hold EXT/FRONT or RET/FRONT (FIG 8-J,H,C) to position
king-pin/gooseneck to proper hitch connection height.
6. Follow hitch manufacturer’s hook-up procedure to tow vehicle and
connect trailer lights harness.
7. Once RV is safely connected to tow vehicle, press RET/FRONT (FIG
7-A,C) to auto retract landing gear. LED’s will go to solid green to
indicate landing gear is fully retracted. A quick visual check of land-
ing gear ground clearance should be done to insure safe towing.
8. Press ON button to turn power off and switch Activation Switch to
OFF (FIG 8-A).
9. Remove Chocks before towing.
Emergency Stop
Leveler extension or retraction in any auto function mode can be
stopped by pressing any button on the key pad. The controller will re-
enter most functions after an emergency stop. If not, retract all level-
ers and begin function from that point.
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
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 overruled by turning the ignition off, then back on.
Low Voltage Protection
•If the voltage falls below 11.5 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.
Front Too Low
• Should the angle of front of the RV drop below level the system
will stop the Landing Gear from retracting and possibly setting
the front of the RV on the ground.
Manual Override
• To Manually Extend or Retract Leveler, use a 1/2˝ socket on Drive
Nut on end of motor (FIG 11).
Rotate nut counter clock-wise (looking from bottom end of nut
[FIG 11) to extend leveler.
NOTE: It takes 500 revolutions of nut to extend/retract leveler 1˝.
CAUTION
PERSONAL INJURY/PRODUCT DAMAGE
•Battery operated drills, 9.6V to 18V, are powerful. Hold drill with both
hands to protect your wrist. Keep loose clothing and body parts away
from drill as the reaction torque from the drill may cause it to kick back.
•Refer to your drill manufacturer’s operation manual.
•Do not over-extend or over-retract levelers. Each leveler has built-in
stops. Excessive force applied against the stops will cause damage.
•When manually overriding the leveler do not use pneumatic tools to
operate any leveler. They can over-extend or over-retract the leveler.
•If the motor will not extend/retract the leveler and the motor is making
a ratcheting sound (clutch slipping), do not use the manual override.
Immediately contact an Atwood Service Center and have leveler
replaced. Do not use the leveler until replaced.
MAINTENANCE
1. Internal parts of leveler are permanently lubricated at the factory
and do not require any further lubrication.
2. If it is not possible to get levelers to operate freely, replace
leveler.
