7STRINGING THE FRAMESetting TensionThe Progression ST utilizes a rotary adjust-ing knob along with a linear tension scale toindicate the tension setting. The scale isdivided into 3 lb increments and each 1/3 turnof the tension knob changes tension by 1 lb.To set the desired tension, rotate the tensionknob and align the mark on the spring guidewith the desired tension setting on the scale.When the “0” mark on the knob aligns with theline on the knob support the tension will bethat indicated on the scale. To increase ten-sion by 1 or 2 lbs turn the knob counterclock-wise until the “1” or “2” mark on the knob aligns with the line on the knob support. To decreasetension by 1 or 2 lbs, turn the knob clockwise until the “2” or “1” mark on the knob aligns withthe line on the knob support.Tensioner Travel StopTo prevent contact between the tension headand the racquet and/or turntable, a stopscrew is located about midpoint along thetensioner bar below the gear track. In theevent the tension head must be moved closerto the racquet, turn the stop screw counter-clockwise with the 5 mm hex wrench until theend of the stop screw no longer protrudesbeyond the surface of the tensioner bar. Tore-engage the stop, simply turn the stopscrew clockwise until the screw is seatedagainst the tensioner bar.Travel StopFixed Clamp Operation - Step 1The fixed clamps for the Progression ST areof a dual action design. The string clamp andthe clamp base operate independently of oneanother.To clamp a string, lift the clamp head andplace the string between the jaws. Depressthe clamp head lever to secure the string.The clamping pressure applied to the stringshould be adjusted to provide sufficient pres-sure to secure the string when subjected tothe desired pulling tension. The diamondcoated gripper plates provide for increasedfriction between the clamps and the string to allow for reduced clamping pressure while securingand holding the string under tension.
