The slightest touch on the weigh bin should result in a change in the readout. If this is not the case, something is wrong. When the light touch is removed, the display should return to its starting point.

    You can increase this delay time if you feel additional mixing is required before release. On model GB/WSB-940, be sure the weigh bin has two baffles installed. These ensure horizontal layering (as opposed to side by side layering) of materials prior to dropping into the mix chamber.
  • Page 92 Modesl GB/WSB-GBM, 100 series, and some 200 series units use an air drive for the mix blade, instead of an electric motor. Air drives have these advantages: a) Improved mixing due to back and forth motion of the blades. b) No EMF (Electro Magnetic Force) feedback to the processor from electrical demands of the motor resulting, the results in less processor problems.
