    MOUNTING THE FRAME Adjusting the Frame Support Posts Loosen the lock bolts of the frame support posts and space them apart with the frame support slides separated by the approxi- mate length of the racquet head.

  • Page 14 MAINTENANCE & ADJUSTMENTS Adjusting the Tensioner Brake Step 1 After stringing many racquets, the brake of the tensioner may need to be adjusted. With the brake lever engaged, loosen the lock bolt located on the back side of the tensioner frame with the 4mm hex wrench. Note: The lock bolt should only be loosened enough to be turned by hand and must not be removed completely.
  • Page 15 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.
