Mount the motor on a ring stand or vertical lattice rod with the clamp provided.
Install the chuck assembly to the motor shaft using the allen wrench provided. Be sure
you tighten the set screw on the flat spot on the motor shaft. Insert the metal stirring shaft

and the motor speed knob is turned fully counter clockwise. Plug the power cord into a
properly grounded and polarized receptacle. Select the desired direction with the
forward/reverse switch. Turn the motor speed knob clockwise to set the motor speed.

Always use proper safety equipment when stirring, for example, gloves, glasses, etc.
Read and follow instructions that are supplied with your stirrer.
When reversing the motor direction, let the motor stop before changing direction.
