STRINGING THE FRAME
Pulling Tension
Wrap the loose section of string once around
the roller guide and insert the string between
the diamoind dust coated string gripper
plates. Pull the string perpendicular to the
gripper plates while slowly rotating the
tensioner crank clockwise until the brake
lever pops out of the latching block. The
string is now tensioned and can be clamped
in place with the remaining fixed clamp.
Repeat the above steps until all main strings
are installed. Tie off ends of main strings as
per racquet manufacturers recommenda-
tions.
Fixed Clamp Operation - Step 2
Rotate the winged lock knob clockwise to
secure the clamp base to the turntable.
Reverse the clamping procedure to unlock
the string clamp.
The winged lock knob should be tightened
enough to prevent clamp base slippage on
the turntable, when the desired tension is
placed on the string. To go from the loose
position to the clamped position and back,
generally requires about 1/2 to 3/4 quarters
of a turn. Although when stringing at ex-
tremely high tensions, additional tightness may be required. Note: If the string slips in the
string clamp while tensioning, adjust the gap between the clamp jaws as per the
instructions on page 11.
Clamping the First Main String
To begin stringing the main strings, thread
the two ends of the string through the two
center holes at the appropriate end of the
frame and continue through the opposite
center holes. Thread one end of the string
through the adjacent grommet hole and pull
excess by hand.
Secure one of the strings using a string
clamp.
