STRINGING THE FRAME
Setting Tension
The Progression STII utilizes a rotary adjusting knob
along with a linear tension scale to indicate the tension
setting. The scale is divided into 3 lb increments and
each 1/3 turn of the tension knob changes tension by 1
lb. To set the desired tension, rotate the tension knob
and align the mark on the spring guide with the desired
tension setting on the scale. When the "0" mark on the
knob aligns with the line on the knob support the tension
will be that indicated on the scale. To increase tension by
1 or 2 lbs turn the knob counterclockwise until the "1" or
"2" mark on the knob aligns with the line on the knob
support. To decrease tension by 1 or 2 lbs, turn the knob
clockwise until the "2" or "1" mark on the knob aligns with
the line on the knob support.
Tensioner Travel Stop
The tensioner bar is equipped with a tensioner travel
stop to limit travel of the tensioner along the bar and
prevent contact between the tensioner and the racquet
mounting system while stringing. The travel stop is
located about midpoint along the tensioner bar below the
gear track.
To disengage the stop, pull and hold the knob, rotate 90
degrees and release. To engage the stop, repeat the
above procedure until the travel stop pin protrudes
beyond the opposite surface of the tensioner bar.
Travel Stop
Clamp Head Operation
Clamps are of a dual action design where
as the clamp head and clamp base operate indepen-
dently of one another.
To clamp a string, lift the clamp head and place the string
between the jaws and depress the clamp head lever to
secure the string. The clamping pressure applied to the
string should be adjusted to provide sufficient pressure
to secure the string when subjected to the desired pulling
tension. The diamond coated gripper plates provide for
increased friction between the clamps and the string to
allow for reduced clamping pressure while securing and
holding the string under tension.
Note: If the string slips in the string clamp while tensioning,
adjust the gap between the clamp jaws per the instruc-
tions on page 13.
