ASSEMBLY INSTRUCTIONS

Installing the Turntable

Remove the turntable from the foam packing of theshipping carton. Insert the center post of the turntableinto the bushing of the stringing machine base.

Engaging the Drop Weight Bar Stop

The stringing machine is shipped with the drop weightbar in the horizontal position. To prevent racquetdamage during stringing, the bar stop must be engaged.

Remove the machine base from the shipping cartonbeing careful to avoid lifting by the plastic cover.

Hold the drop weight bar in the vertical position as shownwhile turning the stop screw clockwise with the supplied5mm hex wrench.

Installing the Frame Support Posts

The Progression 602 support post assemblies are pre-cision aligned at the factory and are marked for properinstallation on the turntable.

Install the support post with the dot on its base to anidentical dot on the turntable. Align the threaded hole inthe bottom of the frame support post with the slot in theturntable. Screw the lever lock bolt with washer into thebottom of the support post and tighten gently.Positionthe washer the rounded side toward the turntable.

Repeat procedure on the opposite side of the turntable

MOUNTING THE FRAME

Adjusting the Frame Support Posts

Place the racquet frame over the center posts and ontothe frame support. Loosen the lever lock bolt on onesupport post. Slide the post outward until the centersupport of the racquet support slide is positioned nearthe inside surface of the racquet frame. Securely tightenthe lever lock bolt.

Adjust the opposite post using the same procedure.

Caution: To avoid racquet damage, the center postsshould not contact the racquet prior to fixing the supportposts.

Adjusting the Frame Shoulder Supports

Being sure the shoulder supports are free to swivel inthier mountings, simultaneously rotate the shouldersupport adjustment knobs clockwise until both shouldersupports gently and squarely contact the frame.

Tighten the Frame Support Slides at the head and throatof the racquet until they gently contact the frame be-tween the two center main string grommets.

Securing the Frame

Lock the shoulder supports in position by turning theknob at the base clockwise.

Repeat the adjustment procedure for the remainingsupport post.

Re-tighten all of the frame supports in the same order asbefore.

Do not overtighten any of the supports as racquetdamage may occur.

The supports should be tightened to the point where theracquet frame will not move in the mounting systemwhen the handle is grasped and attempts are made tomove it. Should any supports lose contact with the framewhile stringing, they should be re-tightened.

STRINGING THE FRAME

The drop weight is of a two piece design. Whenassembled, it will accomodate tensions from 20 lbs. to90 lbs. For tensions from 8 to 20 lbs., remove the 5mmbolt on the face of the drop weight, and use the smallerportion of the weight as described above.

Note: Tensions above 77lbs. require removal of the dropweight bar endcap.

Setting Tension

To set the stringing tension, loosen the locking knob onthe side of the drop weight. Slide the weight in theappropriate direction until the face closest to the stringgripper is indexed with the desired tension mark on thetension bar.

Clamping the First Main String

To begin stringing the main strings, thread the two endsof the string through the two center holes at the appro-priate end of the frame and continue through the oppo-site center holes. Thread one end of the string throughthe adjacent grommet hole and pull excess by hand.Using a floating clamp, secure the center and theadjacent string to each other on the inside of the frame.

STRINGING THE FRAME

Gripping the String

While holding the tension bar slightly above horizontal,wrap the free string clockwise around the gripper drumonce and position between the gripper jaw.

Gently turn the gripper clockwise while squeezing thejaws together until all slack in the string is removed.

Note:Note:Note:Note:Note: For proper operation, the string gripper jaw mustbe in the position shown. The tension in the stringprovides the clamping force to the jaws.

Pulling Tension

While securely holding the string gripper drum with yourhand, lift the tension bar above horizontal and gentlylower the bar under its own weight. If the tension bardrops below horizontal, repeat the above action until thebar comes to rest parallel to the racquet.

When the correct tension is attained, the drop weight barwill rest horizontally as shown. For accurate tensioning,it must be lowered and come to rest at horizontal withoutassistance. Manually forcing the tension bar to thehorizontal position will greatly increase the string ten-sion and may result in racquet damage.If the tension bar comes to rest above horizontal, releasethe string by lifting the bar and re-pull the string.

7

STRINGING THE FRAME

Clamping the String

Clamp the tensioned string to the next adjacent stringusing the second string clamp. Release the string fromthe gripper by raising the tension arm.

Repeat the procedure for all of the remaining mainstrings and tie off following the racquet manufacturersrecommendations.

Starting the Cross Strings

Follow the manufacturer's recommended stringing pat-tern for one or two piece stringing. This will determine thestarting point for the cross strings. If applicable, tie thefirst cross string using an appropriate starting knot.

Weave the cross strings over and under the main stringsbeing careful to alternate the weave of each consecutivecross string so as to be opposite of the previouslyinstalled cross string.

Once the final cross string is tensioned and clamped, tieoff at the appropriate hole specified by the racquetmanufacturer.

8

PATHFINDER AWL

The Gamma 602 includes the new Pathfinder stringingawl which creates a pathway between or around stringsto make inserting a string through tight gromets easierand quicker.

Insert the awl through the grommet hole in the samemanner as for traditional awls. The Pathfinder awl mustbe in the closed position before insertion.

Once the awl is inserted, pull the handle of the awloutward while holding the tip section in place, leavingthe outer sheath in the grommet hole.

Insert the end of the string into the center of the sheath.

While holding pressure on the string, slowly pull thesheath out of the grommet hole to leave the end of thestring exposed.

Adjusting the Clamps

The clamps provided with your stringing machine willneed minor adjustments according to what string type,construction, and gauge you are using.

To adjust, route the string through the racquet as if youwere beginning the main strings. Clamp the strings andpull tension. If the string slips through the jaws of theclamp, tighten the clamp by turning the adjustment knobopposite of the handle, in the clockwise direction. If theclamp leaves impressions or damages the string, it is tootight and must be adjusted by turning the adjustmentknob counterclockwise.

The clamp jaws must be clean and free from dirt, oil, andany string coating for them to grip properly. Clean theclamp jaws with alcohol.

Note: The string clamps supplied with your stringing machine can accomodate tight string patterns such asbadminton. Depending on the string pattern, the clamp will spread the strings slightly which will not compromise thequality of the string job.

MAINTENANCE

Your GAMMA Progression 602 stringing machine is adjusted for optimum performance at the factory and needs nofurther adjustments before use. After extensive use however, the machine may need minor adjusments as follows:

Adjusting the Turntable Bushings

There are two adjustment points on the machine base.One is located beneath the polystyrene base cover whilethe other is accessed from below the machine.

Using the supplied 3mm hex wrench, tighten both setscrews slightly until the turntable rotates smoothly with-out excessive free play.

Repeat procedure until final adjustment is reached.
