Air-Weigh On-Board Scales measure the air pressure in your air-ride suspension system; they calibrate, and convert that information into on the ground weight. Then, that information is displayed in the cab of your truck. While using your on-board scales it is best to read the display on level ground, with the brakes released and the air ride suspension free from any binding. Calibration Calibration is a scientific term that simply means that you are going to carefully enter empty weight and heavy weight information into the on-board scale. Your on-board scale needs to know exactly how much air pressure is in your suspension when your truck is empty and how much pressure exists when you have a heavy load. Calibration is a 2 stage process. You need to enter the corresponding weights to complete the calibration process. Calibration is important, and it can be adjusted. Don’t get two weight tickets and enter the heavy/empty information into the scale at once. Calibration would fail because the scale needs you to enter the weight information when the status of the load matches the empty or heavy status of the truck. PIN Protection A PIN number is entered to protect the calibration information and ensure that no one can tamper with your scale. If you lose the PIN number, call Air-Weigh Customer Support. They can help you unlock the scale, provide a temporary PIN number, and help you reset the PIN protection. Tip: Always PIN protect your scale. LOADMAXX ON-BOARD SCALES 3

two individually programmable alarm outputs, Alarm 1 and Alarm 2. The alarms can be turned off by using the Alarm menu TURN ON/OFF function. Alarms appear as a bell icon shown on the tractor display. The Alarm1 and Alarm2 are available for each axle group: Steer, Drive and Trailer (or for each one of multiple trailers), as well as for Net Payload and GVW. External lights or audible alarms can be added to alert the driver and the loaders when the load is approaching the legal limit. Each alarm can be programmed in two modes: Warning mode, which slowly pulses and Alarm mode, which is on constant. The same alarm can be programmed to pulse and provide steady illumination at different weights. Example: Pulsing at 31,000 lbs. and Steady at 33,000 lbs. GVW Gross Vehicle Weight (GVW). This is the total weight of the loaded vehicle which includes the vehicle itself and the cargo that is loaded on the vehicle. Net Payload By zeroing out the Net Payload prior to loading or unloading, the cargo weight of separate loads can be determined. It’s an excellent tool for solving weight discrepancies with shippers right at the loading site, or calculating the amount of product that has been on/off loaded. 4

You may enter the weight information in any order, but it is important that you enter the axle weight information into the scale twice. Don’t get two weight tickets and enter the information from both tickets at once. The weight ticket information must be entered into the scale when the weight of the truck matches the weight on the ticket. 2 Separate trips to the certified scale are required. - 1 trip with a Heavy load and 1 trip Empty. • Get the first weight ticket • Enter the axle weight shown on the weight ticket immediately as instructed on the following pages into your LoadMaxx scale. Heavy Weight Empty Weight • When the status of your load changes, return to a certified scale. • Get another weight ticket, and immediately enter the weights shown on the ticket into your scale. • Use this guide to assist you. Accurately calibrated LoadMaxx on-board scales will perform within an accuracy rate of 300 lbs per axle group. Tip: The weight ticket information must be entered into the scale when the load on the truck matches the status on the scale. Heavy weight entered when the truck is loaded. Empty weights entered when the truck is empty. 5

calibrate the trailer scale from inside the cab. LoadMaxx Trailer Scales must be PIN protected at the trailer display. PIN Protect your Trailer Scale Air-Weigh recommends that you PIN protect all your scales once they are calibrated. To completely ensure the protection of your calibration information, PIN protect the trailer scale directly on the trailer display. Follow the directions listed on the trailer PIN protection section of this guide. Call Air-Weigh Customer Support with questions 888-459-3247. Calibration of LoadMaxx trailer scale can be completed at the tractor display. If your tractor is attached via the 7-way cord to a trailer which is equipped with LoadMaxx on-board scales, the calibration information is automatically sent to the trailer. The trailer retains the calibration information and can be used with other LoadMaxx equipped tractors without any recalibration requirements. Calibrate LoadMaxx Tractor & Trailer Scales 6

Calibration is a scientific term that simply means that you need to carefully enter an empty weight, and a heavy weight for each axle group into the on-board scale. Your on-board scale already knows exactly how much air pressure is in your suspension when your truck is empty and how much pressure exists when you have a heavy load. You need to enter the corresponding weights shown on the weight ticket to complete the calibration process. Avoid the #1 User Error • Enter EMPTY weight information into your Air-Weigh scale only when the vehicle is EMPTY. • Enter HEAVY weight information into your Air-Weigh scale only when the vehicle is HEAVY. The order that you enter the “Heavy” weight information, or “Empty” weight information, is not important. Calibration is Important - Follow Directions Carefully. Prior to Calibrating the Scale, Follow these 3 Steps. Step 1 - Drive to a reliable certified scale with your vehicle empty/heavy and get a scale ticket showing individual weights for your steer, drive, & trailer axles. Step 2 - Identify a smooth, level area to park you vehicle and roll to a stop, transmission in neutral, brakes released. Step 3 - Dump the air in the suspensions for 5-10 seconds, then re-inflate the suspension to ride height. Calibration instructions continued on the next page 7

Daily use of your on-board scales requires that you make a few adjustments to your routine. To read your scale you need to find a place to stop. 1. Identify a level, smooth area…lightly tap your breaks to slow, with the transmission in neutral...safely glide to a full stop. 2. Do not engage your brakes during the scale reading. Dump air and reinflate to ride height. 3. Wait until a steady weight reading appears on the display. Read and report your axle weight information. Live-Loading If you are live-loading, lightly tap your breaks until you can engage the clutch and safely glide to a full stop at the loading area. The loading area must be level and smooth. There are ways for you to keep the truck from rolling during loading and still get accurate weights: • You can release the clutch pedal with the engine off and the truck in gear, or • You can set either the tractor or trailer parking brake. Do not set both brakes. The idea is to allow the truck to bounce and sag while loading, without binding up the suspensions. Stop loading when the scale indicates you’re approaching the maximum load. Before leaving the load site, it’s a good idea to check your scale again. Release the brakes and briefly dump the suspension air, then allow it to inflate back to ride height. Check the weights shown on the screen...add more to your load if necessary. By using this process you can maximize every load without waiting in line to add product or waste time off-loading excess product. 16
