Model Number Note
This guide is intended for use for scales set to model number 5809.
LoadMaxx Tractor Scale Overview
LoadMaxx is a weighing system for vehicles that works by using a
hydraulic lift sensor. The sensor measures hydraulic lift pressure
changes and converts that number into weight which is displayed in
the truck cab. The scale will display the actual on-ground weight for
the hydraulic lift axle group.
Scale Display Overview
Before using your Air-Weigh Tractor
Scale, you will need to calibrate it.
Below is a denition of the use of each
button. The function and use of these
buttons remain the same throughout all
operations of the scale.

Calibration
For the best calibration results, the tractor and trailer should be:
• Parked on level ground
• Tractor brakes released
• Engine running
• Raise the 5th wheel plate 1.5” o of the stoppers for
HEAVY weight
Once the LoadMaxx Tractor Scale is calibrated, it is not necessary
to re-calibrate unless the suspension or hydraulic lift system
characteristics change.
Assigning a PIN number during the system set-up process will
protect the calibration procedure from tampering. Normally a
PIN number is not assigned until AFTER the scale has been
calibrated. Air-Weigh Trailer Scales also have a PIN lock-out to
prevent tampering when the trailer is parked, however any Air-
Weigh equipped tractor will still have access to the Trailer Scale’s
calibration function through the in-cab truck scale.
Preliminary Considerations
The accuracy of the LoadMaxx Tractor Scale depends on the
accuracy of the certied scale used to calibrate or check-weigh.
Ensure that the in-ground scale is reliable, recently certied and in
good repair. It is preferable to obtain all weight tickets from the same
certied scale. Segmented scales, those that provide individual
axle group weights, are preferred. When segmented scales are not
available, take extra precaution in calculating weights.

Calibrating The Tractor Scale Overview
The order of calibration is not important; however, both EMPTY and
HEAVY weights must be properly entered before the weight display
is accurate. When calibrating, the EMPTY weights must be entered
while the vehicle is empty, and the HEAVY weights must be entered
while the vehicle is fully loaded. Failure to calibrate scales when
vehicle is actually empty and when it has a true heavy load will result
in inaccurate weights.
Calibrating Empty Weights
Leave the 5th wheel plate at the lowest position on stoppers.
1. Press ESC one or more times until the Main Menu appears,
with VIEW WEIGHTS blinking
2. Select PRINT,SETUP
3. Select SYSTEM SETUP
4. Select CALIBRATION
5. Select MANUAL CALIBRATION
6. Select EMPTY WEIGHT
7. The screen pauses for three seconds with
the display, “ENTER EMPTY – VEHICLE
MUST BE EMPTY” before proceeding automatically to the next
menu
8. On the PICK AXL menu, select DRV (Drive) for the hydraulic lift
If PIN is needed for access, enter it at this time
9. Using the up/down arrows ▲ or ▼, enter 20lbs. for your
EMPTY weight and press ENTER. The screen will briey show
Accepted to indicate its acceptance of the Empty Weight
5
Calibrating Heavy Weights
Use a certied scale to get your drive suspension weight. Make
sure the trailer is fully loaded and that the 5th wheel plate is
1.5” o the stoppers when you enter the weight data.
1. Using the same steps you did in entering your Empty
weights, navigate to the HEAVY WEIGHT screen
2. On the PICK AXL menu, select DRV (Drive) for the
hydraulic lift
3. Using the up/down arrows ▲ or ▼ enter your fully loaded
weight obtained from a certied scale for your HEAVY
weight and press ENTER. The screen will briey show
Accepted to indicate its acceptance of the Empty Weight

Operations
Once calibrated, your Air-Weigh LoadMaxx Tractor Scale is
ready to display weights in 20lb (20kg) increments. Continued
accuracy is established by following a few simple rules before
taking weight readings:
1. Park the tractor and trailer on a level surface
2. If equipped with a trailer dump valve, release trailer brakes
and dump air in trailer suspension for 5 – 10 seconds, then
re-inate to factory-specied ride height.
3. Accurate weight is displayed when numbers stop blinking.
4. Ensure the 5th wheel plate is 1.5” above stoppers at same
position as when it was calibrated.

Large Character Display
The Air-Weigh LoadMaxx Tractor Scale can display weights on either
three lines or two lines.
Only the Weights Displays can appear as large characters on two
lines. On this display, axle group names are represented by their rst
letters:
S = STEER
D = DRIVE
T = TRAILER (if one semi trailer, or
full trailer)
F = FRONT TRAILER (full trailer)
R = REAR TRAILER (full trailer)
G = Gross Vehicle Weight (GVW)
N = Net Payload (NET)
A = TRAILER A (if two trailers)
B = TRAILER B (if two trailers)
All other screens always appear as three lines. To change between
two line and three line on the display:
1. Press ESC one or more times until the Main Menu appears,
with VIEW WEIGHTS blinking
2. Select PRINT,SETUP
3. Select SYSTEM SETUP
4. Select SYS CONFIG
5. Select DISPLY SETUP
6. Select WEIGHT SETUP
7. Select 2 OR 3 LINES, leading to the next menu. At the bottom
of the menu the current choice is shown as (Now 2 LINE) or
(Now 3 LINE). At this point you can choose between the two
line display with larger characters, or the three line display.
8. Press the ▲ or ▼ buttons to select 2 LINE DISP or 3 LINE
DISP, and press ENTER
