9Setting TensionThe tensioner utilizes a rotary adjusting knobalong with a linear tension scale to indicatethe tension setting. The scale is divided into3 lb increments and each 1/3 turn of thetension knob changes tension by 1 lb. To setthe desired tension, rotate the tension knoband align the mark on the spring guide withthe 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 increasetension by 1 or 2 lbs turn the knob counter-clockwise until the “1” or “2” mark on the knobaligns with the line on the knob support. To decrease tension by 1 or 2 lbs, turn the knobclockwise until the “2” or “1” mark on the knob aligns with the line on the knob support.STRINGING THE FRAMETensioner Travel StopTo prevent contact between the tensionhead and the racquet and/or turntable, atravel stop is located about midpoint alongthe tensioner bar below the gear track. In theevent the tension head must be moved closerto the racquet, pull and turn the travel stop 90degrees. To re-engage the travel stop,simply pull and turn the travel stop 90 de-grees.Travel StopClamp Head OperationGAMMA “Quick Action” Clamps are of a dualaction design where as the clamp head andclamp base operate independently of oneanother.To clamp a string, lift the clamp head andplace the string between the jaws and de-press the clamp head lever to secure thestring. The clamping pressure applied to thestring should be adjusted to provide suffi-cient pressure to secure the string whensubjected to the desired pulling tension. Thediamond coated gripper plates provide forincreased friction between the clamps and the string to allow for reduced clamping pressurewhile securing and holding the string under tension.
