MOUNTING THE FRAME
Tightening the Frame Supports
TightentheFrameSupportSlidesbyturning
the adjustment knob clockwise until snug
against the racquet frame and slight resis-
tance is felt.
Caution: Overtightening the Center Sup-
portswillstretchtheheadoftheracquetand
could cause racquet damage.
FrameShoulderSupportAdjustment
Being sure the shoulder supports are free to
swivel in their mountings, simultaneously
rotatetheshouldersupportadjustmentknobs
clockwise until both shoulder supports gen-
tly and squarely contact the frame.
Adjusting the Frame Support Posts
Loosen the lock bolts of the frame support
posts and space them apart with the frame
supportslidesseparatedbytheapproximate
length of the racquet head. Although it is not
required, it is good practice to center the
support posts on the turntable. Lock one of
the posts in position by tightening the lock
bolt and position the other post until the
frame support slide is positioned near the
inside surface of the racquet frame. Se-
curely tighten the lock bolt of the second
support post.
Caution: To avoid racquet damage, the center posts should not contact the racquet prior to
locking down the support posts.

6
Securing the Frame
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.
The supports should be tightened to the
point where the racquet frame will not move
inthe mounting system when the handleis grasped and attempts are madeto move it. Should
any supports lose contact with the frame while stringing, they should be re-tightened.
MOUNTING THE FRAME

STRINGING THE FRAME
The drop weight is of a two piece design.
When assembled, it will accomodate ten-
sions from 20 lbs. to 90 lbs. For tensions
from8to20lbs.,removethe5mmboltonthe
face of the drop weight, and use the smaller
portion of the weight as described above.
Note: Tensions above 77lbs. require the
removal of the drop weight bar end cap.
Setting Tension
To set the stringing tension, loosen the lock-
ingknobonthesideof thedropweight.Slide
the weight in the appropriate direction until
the face closest to the string gripper is
indexedwiththedesiredtensionmarkonthe
tension bar.
Getting Started - Clamping the First Main
String
To begin stringing the main strings, thread
the two ends of the string through the two
center holes at the appropriate end of the
frame and continue through the opposite
center holes. Thread one end of the string
through the adjacent grommet hole and pull
the excess by hand. Using a floating clamp,
secure the center and the adjacent string to
each other on the inside of the frame.

Gripping the String
While holding the tension bar slightly above
horizontal, wrap the free string clockwise
around the gripper drum once and position
between the gripper jaw.
Gently turn the gripper clockwise while
squeezing the jaws together until all slack in
the string is removed.
Note:Note:
Note:Note:
Note: For proper operation, the string grip-
per jaw must be in the position shown. The
tension in the string provides the clamping
force to the jaws.
Pulling Tension
While securely holding the string gripper
drum with your hand, lift the tension bar
above horizontal and gently lower the bar
underitsownweight.Ifthetensionbardrops
below horizontal, repeat the above action
until the bar comes to rest parallel to the
racquet.
When the correct tension is attained, the
dropweightbarwillresthorizontallyasshown.
For accurate tensioning, it must be lowered
and come to rest at horizontal without assis-
tance.Manuallyforcingthetensionbartothe
horizontal position will greatly increase the
string tension and may result in racquet
damage.
If the tension bar comes to rest above hori-
zontal, release the string by lifting the bar
and re-pull the string.
WARNING: TO AVOID INJURY, KEEP FINGERS AWAY FROM
GRIPPER JAWS WHILE TENSIONING STRING.
STRINGING THE FRAME

STRINGING THE FRAME
Clamping the String
Clamp the tensioned string to the next adja-
cent string using the second string clamp.
Releasethestringfromthegripperbyraising
the tension arm.
Repeattheprocedureforalloftheremaining
main strings and tie off following the racquet
manufacturers recommendations.
Starting the Cross Strings
Follow the manufacturer's recommended
stringing pattern for one or two piece string-
ing. This will determine the starting point for
the cross strings. If applicable, tie the first
cross string using an appropriate starting
knot.
Completing the String Job
Weave the cross strings over and under the
main strings being careful to alternate the
weave of each consecutive cross string so
as to be opposite of the previously installed
cross string.
Once the final cross string is tensioned and
clamped,tieoffattheappropriateholespeci-
fied by the racquet manufacturer.
Remove the frame from the mounting system by loosening the shoulder supports and frame
supports.

PATHFINDERAWL
The Gamma X-6 includes the Pathfinder
stringing awl which creates a pathway be-
tween or around strings to make inserting a
string through tight gromets 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.
Once the awl is inserted, pull the handle of
theawloutwardwhileholdingthe tipsection
in place, leaving the 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 the sheath out of the grommet hole to
leave the end of the string exposed.

MAINTENANCE and ADJUSTMENTS
YourGAMMAstringingmachineisadjustedforoptimumperformanceatthefactoryandneeds
nofurtheradjustmentsbeforeuse.Afterextensiveusehowever,themachinemayneedminor
adjusments as follows :
Turntable Bushing Adjustment
The turntable bushing is adjusted at the
factory for optimum performance. After time
and use, the turntable bushings may need
minor adjustment. An adjustment is indi-
cated when noticeable turntable looseness
or wobble occurs while stringing.
To adjust the fit between the turntable pin
and the bushings, tighten the set screw at
the top of the bushing using a 3mm hex
wrench. Tighten until the turntable rotates
smoothly without excessive free play.
Adjustment
Knob
Adjusting the Clamps
The clamps provided with your stringing
machine will need minor adjustments ac-
cording to string type, construction, and
gauge.
Toadjust,routethestringthroughtheracquet
as if you were beginning the main strings.
Clamp the strings and pull tension. If the
string slips through the jaws of the clamp,
tighten the clamp by turning the adjustment
knoboppositeofthehandle,intheclockwise
direction. If the clamp leaves impressions or
damages the string, it is too tight and must
be adjusted by turning the adjustment knob counterclockwise.
The clamp jaws must be clean and free from dirt, oil, and any string coating for them to grip
properly. Clean the clamp jaws with alcohol.
Note: The string clamps supplied with your stringing machine can accomodate tight string
patternssuchasbadminton.Dependingonthe string pattern, the clamp willspreadthestrings
slightly which will not compromise the quality of the string job.
