PDF Calibrating Concrete Mobile Mixers

If too much concrete is being produced, the box is overfilling, or too little concrete is being produced to fill the box level, make minor adjustments in the mix settings to obtain the proper yield. Adjustments should be made in increments of 0.1 on the Stone Dial, up or down as required. Perform tests as outlined above for each change.
