MOUNTING THE FRAME Frame Shoulder Support Adjustment Being sure the shoulder supports are free to swivel in their mountings, simultaneously rotate the shoulder support adjustment knobs clock- wise until both shoulder supports gently and squarely contact the frame. Securing the Frame Shoulder Clamps Lock the shoulder supports in position by turning the knob at the base clockwise.
STRINGING THE FRAME String Clamp Operation The string c lamps are a dual action design where the string clamp and clamp base operate independently of one another. 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.

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. The string must pass over the top half of the gripper before being placed between the gripper jaws, as the tension on the string provides the clamping force to the gripper jaws.

STRINGING THE FRAME Weaving the Cross Strings Weave the cross strings over and under the main strings being careful to alternate the weave direction of each consecutive cross string so as to be opposite of the previously installed cross string. Completing the String Job Once the final cross string is tensioned and clamped, tie off at the appropriate hole speci-...
ADDITIONAL FEATURES Turntable Brake The turntable may be locked in any position. Rotate the lever to the right to lock the turntable and to the left to relase the turn- table.
PATHFINDER AWL The machine includes the Pathfinder string- ing awl which creates a pathway between or around strings to make inserting a string through tight 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.
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.
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.
TROUBLESHOOTING TIPS PROBLEM SOLUTION String slips in clamps - Adjust gap between clamp jaws - Clean clamp jaws String slips in gripper - Clean gripper jaws - Make sure string is wrapped over top jaw of gripper prior to inserting between gripper jaws String clamp base slips on turntable - Clean bottom of clamp &...
