ASSEMBLY INSTRUCTIONS
Installing the Tensioner
Remove the button head screw and washer located at the end of the tensioner bar with the 3 mm hex wrench provided. Slide the tensioner onto the bar, being careful to align the bar with all of the bearings and the drive gear with the gear track. Replace the button head screw and washer in the end of the tensioner bar.
Installing the Crank Arm
Remove the flat head screw located on the crank shaft with the 2.5mm wrench provided. Slide thecrank handle over the crank shaft while aligning the holes. Replace the flat­head screw.
T ravel Stop
Note: The tensioner bar is equipped with a tensioner travel stop screw to limit travel of the tensioner along the bar and prevent con­tact between the tensioner and the racquet mounting system while stringing. The stop screw is located about midpoint along the tensioner bar below the gear track. To en­gage the stop, turn the stop screw clockwise until fully seated against the bar. To disen­gage the stop screw, turn it counter clock­wise until it no longer protrudes beyond the surface of the bar.

Adjusting the Frame Support Posts
Place the racquet frame over the center support slide and onto the frame support. Loosen the lever lock bolt on one support post. Slide the post outward until the center support of the racquet support slide is posi­tioned near the inside surface of the racquet frame. Securely tighten the lever lock bolt.
Adjust the opposite post using the same procedure.
Caution: To avoid racquet damage, the sup­port slide should not contact the racquet prior to fixing the support posts.
Height Adjustment
The turntable height of the GAMMA 6002 can be adjusted to suit the stringer. To adjust, loosen the two set screws on the lower col­umn support post below the bellows assem­bly. Adjust the amount of engagement be­tween the upper and lower column supports until the desired height is attained. Make sure that the tension track is still aligned with the long leg of the base and tighten the two set screws to lock the upper support column into place.
Shoulder Support Adjustment
The shoulder supports on the GAMMA 6002 are adjustable to provide support to the racquet frame. Loosen the knurled knob at the bottom of the shoulder support and swivel the support so that the pads will contact the frame squarely when the arms are closed against the racquet. Should the shoulder supports block string holes, adjust the posi­tion of the racquet between the arms until the shoulder supports contact the racquet be­tween grommet holes.
MOUNTING THE FRAME
Page 11

MOUNTING THE FRAME
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 until firm contact is made between the shoul­der 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 clock­wise. Adjust the slides in equal increments until slight resistance is felt.
Apply a final adjustment to all racquet sup­port 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, as needed, to maintain contact with the frame.

Setting Tension
The GAMMA 6002 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. When the “0” mark on the knob aligns with the line on the knob support the tension will be that indicated on the scale. To increase ten­sion by 1 or 2 lbs turn the knob counterclock-
wise until the “1” or “2” mark on the knob aligns with the line on the knob support. To decrease tension by 1 or 2 lbs, turn the knob clockwise until the “2” or “1” mark on the knob aligns with the line on the knob support.
Fixed Clamp Operation
The fixed clamps supplied with your GAMMA
6002 are of a dual action design. The string
clamp and the clamp base operate indepen-
dently of one another.
To clamp a string, lift the clamp head and
place the string between the jaws. Depress
the clamp head lever to secure the string.
Fixed Clamp Operation
Rotate the winged lock knob clockwise to
secure the clamp base to the turntable.
Reverse the clamping procedure to un-clamp
the string.
Note: If the string slips in the string clamp
while tensioning, adjust the gap between the
clamp jaws as per the instructions on page
14.
STRINGING THE FRAME
Page 13
12
STRINGING THE FRAME
Pulling Tension
Wrap the loose section of string once around
the DIABLO and insert the string between the
diamoind dust coated string gripper plates.
Pull the string perpendicular to the gripper
plates while slowly rotating the tensioner
crank clockwise until the brake lever pops out
of the latching block. The string is now
tensioned and can be clamped in place with
the remaining fixed clamp.
Repeat the above steps until all main strings
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, tie off at the appropriate hole speci-
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.

PATHFINDER AWL
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
the same manner as for traditional awls. 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
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.

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 located on
the other end of the calibrator into the string
tensioner and apply tension. If the brake
lever releases before 60 lbs. or after 60 lbs.,
the tension head should be calibrated as
follows.
Tension Calibration Procedure
Step 2
Loosen the plastic locking screw (A) located
on the side of the latching block as shown.
The plastic screw is used to hold the adjust-
ment screw in place.
Tension Calibration Procedure
Step 3
If the lever releases before 60 lbs., using the
supplied L-shaped hex wrench, turn the
adjustment screw (B) located on the left side
of the latch block counter-clockwise to in-
crease the engagement of the brake release
latch with the brake lever. Repeat step 1 and
adjust until the correct tension is indicated on
the calibrator.
If the tension indicated in step 1 is greater
than 60 lbs., turn the adjustment screw clock-
wise to reduce the engagement of the brake
release latch with the brake lever. Repeat
step 1 and adjust until the correct tension is
indicated on the calibrator.

Adjusting 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
lever on the back side of the tensioner frame
using the 3 mm hex wrench. With the brake
lever released remove the cover.
Adjusting the Tensioner Brake
Step 2
With the cover removed, and the 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
the nut located at the base of the brake lever.
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
along the track with the brake lever engaged
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.
