Atwood Levelegs™ Levelers are intended for use on recreational vehicles, 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 corresponding 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 facing 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 tighten. 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.

2.Run through Unhooking From Tow Vehicle and Leveling RV and
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 suggested 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 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.
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 landing 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 reenter most functions after an emergency stop. If not, retract all levelers and begin function from that point.
CAUTION
PRODUCT DAMAGE
•Do not move vehicle until levelers and landing legs are fully retracted.
