GUIDELINES AND PRECAUTIONS
• To activate the stirrer, tighten the end cap about ¼ turn. This starts the motor;
the stir bar will begin to spin. To stop the motor, back off the cap until the stir bar
stops spinning.
• Replace batteries with 2 standard alkaline D-cells, – toward the end cap,
+ toward the stir bar compartment.
• When attaching to the restrictor or Cal Cup, be careful not to over-tighten.
• The stir bar guard may be removed for cleaning when necessary. Insert the
sensor removal tool into the center rings and pop the guard out.
• Inspect o-rings regularly; replace if they show evidence of wear or damage (o-
rings & lubricant available from In-Situ Inc. or your distributor).
