Align the holes in the leg flange with the
matching holes in the lower column support
post. Secure the leg with one FLAT HEAD
cap screw through the upper hole, and one
SOCKET HEAD cap screw through the bot-
tom hole. Repeat this procedure for the
three remaining legs.
Upper Column Support Assembly
Insert the upper column support into the
lower column support / base leg assembly.
Leave the upper column extended to maxi-
mumheightandlockinplacewiththetwoset
screwslocatedatthetopofthelowercolumn
support.
ASSEMBLYINSTRUCTIONS
Base Leg Assembly
TheGAMMA6004stringingmachineusesa
four leg base design. The legs must be
assembled to the support post before use.
Remove the lower column support from the
carton.

ASSEMBLYINSTRUCTIONS
Tension Track Installation
Placethetube ofthe tensiontrackassembly
over the top of the upper column support.
Alignthetensiontrackwiththelonglegofthe
base assembly. Securely tighten the two
socket set screws on the tension track as-
sembly tube, locking it to the upper column
support. Align the notch in the tool tray with
the tension track bar while raising the tool
tray. Secure the tray with the set screws in
the side of the tray casting.
Tool Tray Installation
Lower the tool tray over the top of the upper
column support and let it rest loosely on the
bellows assembly.
Bellows Installation
The bellows assembly is supplied in two
piecesand shouldbe assembledas follows.
Place the bellows section with the flange
over the upper support column with the
flange on the top. Place the remaining bel-
lows over the upper support column and
mate it with the flange on the lower bellows.

ASSEMBLYINSTRUCTIONS
TurntableInstallation
Remove the nuts from underneath of the
turntable. Position the 4 screws over the
flange of the turntable pin. Engaging the
turntable brake helps position the screws.
Attach the turntable to the turntable pin
flange using the 4 included M6 cap screws.
Tighten securely.
HeightAdjustment
The turntable height 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
heightisattained.Makesurethatthetension
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.

ASSEMBLYINSTRUCTIONS
CrankArm Installation
Remove the flat head screw located on the
crankshaftwiththe2.5mmwrenchprovided.
Slide the crank handle over the crank shaft
while aligning the holes. Replace the flat-
head screw.
Tensioner Installation
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.
ClampHeadInstallation
The post of the string clamp head and the tube of the
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.
