“How do I pre-stretch while stringing?”
Pre-stretch is built in. Set the amount you want, if any. At 50 pounds plus 15% you will see the digital read-out go to 57.5 pounds, pause, then return to the set point.

“Is there a way to increase the tension for knots?”
Yes. Use the pre-stretch button (see above).

“Will the 2086 work on my machine?”
Call us at 888-836-7466 with the name and model of your machine and we can tell you.

“Can I calibrate the machine?”
After every pull the machine resets its zero point and checks its electronics. If you have a scientific guage to measure tension we can tell you how to calibrate the 2086 from the front panel. A spring calibrator is usually not accurate enough. At any time the machine can be sent to Wise USA for a free re-calibration checkup. We only charge for return shipping. Or, you can verify the accuracy of the 2086 using the precision of the Tennishead™ 2090, our professional programmable calibrator.
