ASSEMBLY INSTRUCTIONS Turntable Installation To install the turntable remove the four nuts underneath holding the mounting bolts in place. Position the turntable over the turn- table pin and align the bolts with the holes in the flange. Secure them with the included allen wrench.

ASSEMBLY INSTRUCTIONS Clamp Head Installation The post of the string clamp head and tube of the string clamp base are treated with grease to provide protection against corro- sion during shipping. Remove any exces- sive grease with a clean cloth prior to use. The post and tube may also be cleaned with isopropyl alcohol.
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 approximate length of the racquet head. Although it is not required, it is good practice to center the support posts on the turntable.

MOUNTING THE FRAME Securing the Frame Shoulder Clamps Lock the shoulder supports in position by turning the knob at the base clockwise. Repeat the adjustment procedure for the remaining support post. Re-tighten all of the frame supports in the same order as before. Do not overtighten any of the supports as racquet damage may occur.
STRINGING THE FRAME Setting Tension The STII utilizes a rotary adjusting knob along with a linear tension scale to indicate the tension setting. The scale is divided into 3 lb increments and each 1/3 turn of the tension knob changes tension by 1 lb. To set the desired tension, rotate the tension knob and align the mark on the spring guide with the desired tension setting on the scale.

STRINGING THE FRAME Clamp Head Operation Quick Action Clamps are of a dual action design where the clamp head 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 clamp head lever to secure the string.

STRINGING THE FRAME Pulling Tension Wrap the loose section of string once around the roller guide and insert the string between the diamond dust coated string gripper plates. Pull the string perpendicular to the gripper plates while slowly rotating the tensioner crank clock- wise until the brake lever pops out of the latching block.
PATHFINDER AWL The machine includes the Pathfinder string- ing awl which creates a pathway between and 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 Tension Calibration Procedure Step 1 Set the tension to 60 lbs. as indicated by the linear scale and rotary knob. Place the string on one end of a tension calibrator into a string clamp and secure. Place string lo- cated on the other end of the calibrator into the string tensioner and apply tension.

MAINTENANCE & ADJUSTMENTS Adjusting the Tensioner Brake 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.

MAINTENANCE & ADJUSTMENTS Adjusting the Clamp Jaws The Quick Action 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.
