DISTRIBUTION AR 3966746 - Caterpillar

In order to obtain an accurate weight, make sure that the pins are lubricated on the lift arm linkage. The hydraulic oil is warmed up to the normal operating temperature. In order to weigh a bucket of material, lift a loaded bucket. The bucket should be racked back fully. Move the lift lever smoothly into the full detent position. The loaded bucket will be weighed as the bucket travels through the upper lifting range. As the bucket is being weighed, the top line of the display will show "WEIGH". The bottom line will show dashes.When weighing is completed, the top line will show the weight of the bucket. If the operator lifts a significantly larger load that exceeds the calibration weight by 50%, the message "MAX" will appear on the display. If this message appears, dump some material from the bucket and lift again. If the "MAX" message appears repeatedly, recalibration is required.See Operation and Maintenance Manual, "System Calibration" for information on recalibration. The weight will be displayed in the selected units. The possible units are shown below.

Lb X 1000The bottom line of the display will show the accumulated weight of the truck. This weight is from the last time "STORE" or "CLEAR" was pressed.The rpm of the engine should be kept constant through the lifting range. Avoid directional shifting or harsh turning in order to ensure accurate weighing.Note: If the lift system has been idle for more than 4 hours, the error message "LIFT BUCKET 10 TIMES" will appear on the display when the operator lifts the bucket.See Operation and Maintenance Manual, "Normal Weighing Mode" for information on the error message.
