OUCH ODE PERATION
NOTE: Due to the robust mechanical design of this unit, more downward
force is required to operate this unit in Touch Mode to mix single tubes
as compared to other models. Another option is to set your unit to the
ON mode for mixing a single tube.

PERATING IP
To ensure the stability of your vortex mixer, it is very important to start
with a smooth, clean work surface and the mixers (4) feet. If the mixer
starts to "walk", remove the power to the unit and clean the work surface
and the (4) feet with isopropyl alcohol.

1. Make sure the 3-way rocker switch is in the center, off position. Plug
the power cord into a properly grounded outlet.
2. For continuous operation, push the rocker switch to the right, on
position. For intermittent/touch operation, push the rocker switch to
the left, touch position.
3. In either case, turn the speed knob to the desired setting. In the on
position, you will see the head in motion immediately. In the touch
position, the vessel you are using must be pushed down on the head
attachment to achieve motion. To get the desired mix, vary the speed,
using the speed knob, and/or vary the angle of contact and pressure
against the head.
4. When finished with either continuous or intermittent/touch operation,
return rocker switch to the center, off position.
5. The continuous, on mode is for the accessories.
6. The intermittent, touch mode is intended for short mixing times of
one (1) minute or less at full speed.
7. To completely cut off power to the unit, disconnect the power cord
from the wall outlet.
