To clamp a string, lift the clamp head and place the string between the jaws and de- press the string clamp lever to secure the string.
  • Page 10 STRINGING THE FRAME Pulling Tension To pull tension, wrap the free string clock- wise around the gripper drum and position the string between the gripper jaws.

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.

    MAINTENANCE & ADJUSTMENTS Adjusting the String Clamp Jaw Spacing The string clamps will need minor adjustments according to what string type, construction, and gauge you are using. To adjust the gap (clamping pressure) between the clamp jaws, insert the string through the racquet as if you were beginning the main strings.
  • Page 15: Calibration
