TROUBLESHOOTING TIPS
CARE & CLEANING
With time and use, the clamping surfaces of your machine may become oily or dirty and result
in string or clamp slippage while stringing. Periodic cleaning of the String Clamps, String Clamp
Base and String Gripper is recommended. Knife sharpening stones work well for cleaning the
diamond coated string clamping surfaces. Cleaning with a solvent such as isopropyl alcohol
and a mild abrasive tool such as a toothbrush also works well to remove oily or greasy build up.

Instructions for Power Connection and Controls
CAUTION ! Before connecting to the power supply, check the voltage source that the
machine is being connected to.
The acceptable range of input voltages for this ma-
chine is between 100 V and 240 V @ 50 to 60 Hz. If you have any questions regarding
the input voltage supply for your area, please ask your electric utility company.
To install the power cord, insert the female end of the power cord into the AC Adapter and
then insert the female end of the cord from the AC Adapter into the A/C Power Cord Socket
“C” located on the back panel of the tensioner. Plug the male end of the power cord into a
grounded power outlet. When using extension cords, use grounded heavy duty extension
cords rated for 15 AMP service.
To connect the foot pedal switch, insert the male pin at the end of the foot pedal switch cord
into the Foot Pedal Switch Receptacle “B” located on the back panel of the tensioner.
Switch on the machine by pressing the Lighted On-Off Power Switch on the back panel. At
start-up, the LED will display a countdown from “9.0” to “0.0” while the machine performs a
