Centering your sample and even weight distribution on the tray helps with balance and
stability. As a safety feature, a built-in program will shut power off to the motor if the
tray is prevented from rotating, or the unit is overloaded beyond its recommended
weight capacity. To reset the unit, press the rocker switch to standby and then press
the rocker switch to the on position. The shaker will automatically restart after a power
interruption. Built-in memory maintains the last used speed and time settings during
a power interruption.
To prevent the rubber mat from sliding, remove backing from adhesive on the under-
side of mat, reposition in tray, and firmly press.
