MOUNTING THE FRAME Adjusting the Inner Racquet Supports The white racquet supports are adjustable to accommodate all racquets and provide maximum support to the racquet frame. Screw the pads up or down so they contact the frame at a maximum height without blocking the grommet holes. Special Throat Mounting For racquets with a bridge that is thinner than the rest of the frame or are tapered from head...
MOUNTING THE FRAME Installing the Racquet Hold Down With the lever in the up position, insert the racquet hold down pin into the hole in the center of the mounting post. Depress the racquet hold down lever to secure the racquet frame.

STRINGING THE FRAME Getting Started 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.
Page 15
STRINGING THE FRAME To apply tension to a string, push the tension switch or the foot pedal. The string gripper will rotate and slowly apply tension to the string. When the set tension has been attained, the gripper will stop rotating. As the tensioned string stretches, the gripper will continue to pull and rotate intermittently, maintaining the set tension.
STRINGING THE FRAME Completing the String Job Once the final cross string is tensioned and clamped, tie off at the appropriate hole speci- fied by the racquet manufacturer. Remove the frame from the mounting system by loosening the mounting stands. ADDITIONAL FEATURES Turntable Brake The turntable may be locked in any position.
STRING LENGTH METER OPERATION To enable the String Length Meter (SLM) function, press the String Length button on the keypad. When the String Length but- ton is pressed, one of the LED indicators above “M” or “FT” will light up to indicate that the SLM function is enabled.
PATHFINDER AWL The machine includes the Pathfinder string- ing awl which creates a pathway between or around strings to make inserting a string through blocked grommets easier and quicker. Insert the awl through the grommet hole in the same manner as for traditional awls. The Pathfinder awl must be in the closed position before insertion.
Most tension calibrators (such as a Gamma Tension Calibrator) function by clamping off the string attached to one the end of the calibrator and applying tension to the string located on the opposite end of the calibrator.
