MOUNTINGTHEFRAME
Securing the Shoulder Supports
Secure the racquet frame with the shoulder
supports by rotating the large adjustment
knobs on the outside of the support post
assemblies clockwise. Adjust the supports
untilfirmcontactismadebetweentheshoul-
der supports and the frame.
The tear drop shaped holes torwards the
back of the shoulder supports are handy
for holding the loose end of the string
while pulling the string through the
racquet. Simply insert the loose end into
the tear drop shaped holes and slide the
string into the point of the hole.
Support Slide Adjustment
Once the frame support posts are secured,
lightly tighten the support slides by turning
the knobs on the outside of the slides clock-
wise. Adjust the slides in equal increments
until slight resistance is felt.
Apply a final adjustment to all racquet sup-
port points until the racquet is firmly secured
in the mounting system.
Should the frame supports lose contact with
the frame while stringing, they should be
adjusted,asneeded,tomaintaincontactwith
the frame.

Setting Tension
TheGAMMA6002utilizesarotaryadjusting
knob along with a linear tension scale to
indicate the tension setting. The scale is
dividedinto3lbincrementsandeach1/3turn

tensioned and can be clamped in place with
the remaining fixed clamp.
Repeattheabovestepsuntilallmainstrings
are installed. Tie off ends of main strings as
per racquet manufacturers recommenda-
tions.
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.
Once the final cross string is tensioned and
clamped,tieoffattheappropriateholespeci-
fied by the racquet manufacturer.
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
excess by hand.
Secure one of the strings using a string
clamp.

PATHFINDERAWL
The GAMMA 6002 includes the new Path-
finder stringing awl which creates a pathway
between or around strings and through tight
grommets.
Insert the awl through the grommet hole in
thesame mannerasfortraditionalawls. The
Pathfinder awl must be closed before inser-
tion.
Once the awl is inserted, pull the handle of
the awl outward while holding the tip section
in place, leaving the outer sheath in the
grommethole.
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.

AAdjusting the Tensioner Brake
Step 1
After stringing many racquets, the brake of
the tensioner may need to be adjusted. To
tighten the braking mechanism, the cover of
the tensioner must be removed. To remove
the cover, remove the 2 button head screws
located on the back side of the tensioner
frame near the top of the frame, and the flat
head screw located behind the tensioner
leveronthe back side of thetensionerframe
using the 3 mm hex wrench. With the brake
lever released remove the cover.
Adjusting the Tensioner Brake
Step 2
Withthecover removed,andthe brake lever
engaged, loosen the lower hex bolt located
on the back side of the tensioner frame with
the 10 mm box wrench. Note: The hex bolt
should only be loosened until loose enough
to turned by hand and must not be removed
completely.

Adjusting the Tensioner Brake
Step 3
With the hex bolt loosened and the brake
lever engaged in the latch, insert the 6 mm
hex wrench into the set screw locted inside
thenutlocatedatthebaseofthebrakelever.
To tighten the braking mechanism, turn the
set screw counter clockwise by about 1/8
tunr. Retighten the hex bolt on the back side
of the tensioner frame and check for brake
tightness. The tensioner should move freely
alongthetrack with thebrakeleverengaged
and should hold tension with the brake lever
released. If more adjustment is needed, repeat steps above until properly adjusted. After
adjustment is complete, replace the tensioner cover by aligning the holes of the cover with the
holes in the tensioner frame and secure with the 2 button head screws and flat head screw.
