string clamp base are treated with grease to provide
protection against corrosion during shipping. Remove
any excessive grease with a clean cloth prior to use.
The post and tube may also be cleaned with isopropyl
alcohol. After this type of thorough cleaning, the post
and tube should be treated with a light coating of
machine oil to protect the surfaces against corrosion
and to ensure smooth operation.

ASSEMBLYINSTRUCTIONS
Setting the Gripper Jaw Spacing
The gripper jaws of the 6004 tensioner are
adjustable to accomodate varying string
gauges.
If the string slips through the gripper jaws
while pulling tension, rotate the gripper jaw
adjustment screw counter-clockwise.
Ifthestringisdamagedwhilepullingtension,
rotatethegripperjawadjustmentscrewclock-
wise.
The jaws will be properly adjusted when
thereisenoughpressuretosecurelygripthe
string without causing damage to the string.
TravelStop
Note: The tensioner bar is equipped with a
tensioner travel stop to limit travel of the
tensioner along the bar and prevent contact
betweenthetensionerandtheracquetmount-
ing system while stringing. The travel stop is
located about midpoint along the tensioner
bar below the gear track.
To disengage the stop, pull and hold the
knob, rotate 90 degrees and release. To
engage the stop, repeat the above proce-
dure until the travel stop pin protrudes be-
yond the opposite surface of the tensioner
bar.
MOUNTINGTHEFRAME
FrameSupport Post Adjustment
Place the racquet frame over the center
support slide. Screw the the post outward
until the center support of the racquet sup-
portslide ispositioned on theinside surface
of the racquet frame.

MOUNTINGTHEFRAME
ShoulderSupportAdjustment
The shoulder supports are adjustable to
providesupporttotheracquetframe. 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 posi-
tionoftheracquetbetweenthearmsuntilthe
shoulder supports contact the racquet be-
tween grommet holes.
Securingthe 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
untilfirmcontactis madebetweentheshoul-
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
pullingthestringthroughtheracquet.Simply
insertthelooseendintotheteardropshaped
holesand slidethe string intothe pointofthe
hole.
FrameSupportSlideAdjustment
The Frame Support Slide should only be
adjusted if the Shoulder Supports are blocking
a grommet hole. Never unscrew the Frame
Support Slide past the machined line on the
lower horizontal portion.
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.

STRINGINGTHEFRAME
SettingTension
The spring tensioner utilizes a rotary adjust-
ing knob along with a linear tension scale to
indicate the tension setting. The scale is
dividedinto3lbincrementsandeach1/3turn
of the tension knob changes tension by 1 lb.
Tosetthedesiredtension, rotatethetension
knob and align the mark on the spring guide
withthe desired tensionsetting on the scale.
Whenthe“0”markontheknobalignswiththe
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 counter-
clockwise 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.
ClampHead Operation
Cam-Lock Clamps are of a dual action
design where as 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.The clamping pressureapplied to the
string should be adjusted to provide suffi-
cient pressure to secure the string when
subjectedtothedesiredpullingtension.The
diamondcoatedgripperplatesprovideforincreasedfrictionbetweentheclampsandthestring
to allow for reduced clamping pressure while securing and holding the string under tension.
Clamp Base Operation
Rotate the Base Locking Lever clockwise to
secure the clamp base to the turntable.
Reverse the clamping procedure to unlock
thestringclamp.TheLockingLeverisspring
loaded to assist the unlocking of the clamp
base.
TheLockingLevershouldbetightenedenough
to prevent clamp base slippage on the turn-
table, when the desired tension is placed on
thestring.Togofromtheloosepositiontothe
clamped position and back, generally re-
quires the travel permitted by the clamp base. If the travel is not sufficient to allow smooth
operation of, adjust the Clamp Base as outlined on page 14.

Pulling Tension
Wrap theloosesectionofstringoncearound
the roller 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.
Repeattheabovesteps untilallmainstrings
are installed. Tie off ends of main strings as
per racquet manufacturers recommenda-
tions.
CompletingtheStringJob
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.
ClampingtheFirstMainString
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.
Pull the remaining end of the string with the
tensioner to the desired tension. Secure the
string with the remaining clamp.

The GAMMA 6004 includes the Pathfinder
stringing awl which creates a pathway be-
tween or around strings and through tight
grommets.
Insert the awl through the grommet hole in
thesamemannerasfortraditionalawls.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.
