ASSEMBLYINSTRUCTIONS
Base Leg Assembly
The stringing machine uses a four leg base
design. The legs must be assembled to the
support post before use. Remove the lower
column support from the carton. This is the
larger of the two posts and has the GAMMA
label.
Note: For illustration purposes, the support
column has been painted white for these
instructions.
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-
tomhole.Repeatthisprocedureforthethree
remaining legs.
Base Foot Height Adjustment
Each foot of the Base Stand can be ad-
justed to compensate for uneven surfaces.
UpperColumnSupportAssembly
Insert the upper column support into the
lower column support / base leg assembly.
Leave the upper column extended to maxi-
mumheightandlockinplacewiththetwoset
screws located at the top of the lower
column support.

5
BellowsInstallation
The bellows assembly is supplied in two
pieces and should be assembled as 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.
ToolTrayInstallation
Lower the tool tray over the top of the upper
column support and let it rest loosely on the
bellows assembly.
TensionTrack Installation
Placethetube of the tension track assembly
over the top of the upper column support.

Turntable and Mounting System In-
stallation
To install the turntable remove the four nuts
underneath holding the mounting bolts in
place. Align the bolts with the holes in the
turntable pin. Secure them with the included
allen wrech.
NOTE:Applyingtheturntablebrakewillmake
it easier to align the bolts and holes.
LockingtheTurntable
The turntable may be locked in any position.
The turntable winged lock knob is packed
separately. Install the lock knob into the
threaded hole located on the side of the
tensioner bar post.
Rotate the knob clockwise to lock the turn-
table, and counter-clockwise to release the
turntable.
InstallingtheTensioner
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.

ASSEMBLYINSTRUCTIONS
Setting the Gripper Jaw Spacing
The gripper jaws of the tensioner are adjust-
able 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,
rotate the gripper jaw adjustment screw
clockwise.
The jaws will be properly adjusted when
thereisenoughpressuretosecurelygripthe
string without causing damage to the string.
MOUNTINGTHEFRAME
AdjustingtheFrameSupportPosts
Loosen the lock bolts of the frame support
posts and space them apart with the frame
support slides separated by the approxi-
mate 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
boltandpositiontheotherpostuntiltheframe
support slide is positioned near the inside
surface of the racquet frame. Securely
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.
TighteningtheFrameSupports
Tightenthe FrameSupportSlides byturning
the adjustment knob clockwise until snug
against the racquet frame and slight resis-
tance is felt.
Caution: Overtightening the Center Sup-
ports will stretch the head of the racquet and
could cause racquet damage.

MOUNTINGTHEFRAME
Adjusting the Frame Shoulder Sup-
ports
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.
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.
Thesupportsshouldbetightenedtothepoint
where the racquet frame will not move in the mounting system when the handle is grasped
and attempts are made to move it. Should any supports lose contact with the frame while
stringing, they should be re-tightened.

SettingTension
Thetensionerutilizesarotaryadjustingknob
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
tensionknob changestensionby 1lb.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.
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-
clockwiseuntilthe“1”or“2”markontheknob
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.
STRINGINGTHEFRAME
TensionerTravel Stop
To prevent contact between the tension
head and the racquet and/or turntable, a
travel stop is located about midpoint along
thetensioner barbelow thegeartrack.Inthe

degrees. To re-engage the travel stop,
simply pull and turn the travel stop 90 de-
grees.
Travel Stop
ClampHeadOperation
GAMMA“QuickAction”Clampsareofadual
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 pressure applied to the
string should be adjusted to provide suffi-
cient pressure to secure the string when
subjectedtothedesiredpulling tension. The
diamond coated gripper plates provide for
increased friction between the clamps and the string to allow for reduced clamping pressure
while securing and holding the string under tension.

10
STRINGINGTHEFRAME
PullingTension
Wrap the loose section of string once
around the roller guide and insert the string
between the diamoind dust coated string
gripper plates. Pull the string perpendicular
tothegripperplates 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.
Repeattheabovestepsuntilallmainstrings
are installed. Tie off ends of main strings as
per racquet manufacturers recommenda-
tions.
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.
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.
The Locking Lever should be tightened
enough to prevent clamp base slippage on
the turntable, when the desired tension is
placed on the string. To go from the loose
position to the clamped position and back, generally requires the rotation permitted by the slot
in the clamp base. If the rotation is not sufficient to allow smooth operation, adjust the Clamp
Base Locking Nut as outlined on pg 11.
Note: If the string slips in the string clamp while tensioning, adjust the gap between the clamp
jaws as per the following instructions.

11
STRINGINGTHEFRAME
Weaving the Cross Strings
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.
Adjusting the Clamp Base Locking
Nut
In the event the Locking Lever rotation is
insufficient to ensure smooth operation of
the clamp base, very minor adjustments to
the Clamp Base Locking Nut can be made
with the supplied 17mm socket wrench.
Tightenorloosenthelockingnutinverysmall
increments to provide more clamping pres-
sure or running clearance as needed.
Adjusting the Clamp Jaws
The GAMMA “Quick Action” Clamps will need minor
adjustments according to what string type, construction,
and gauge you are using.
Toadjustthegap(clampingpressure)betweentheclamp
jaws, insert the string through the racquet as if you were
beginning the main strings. Clamp the strings and pull
tension. If the string slips through the jaws of the clamp,
tightentheclampbycompressingtheclampjawstogether
by hand while turning the Adjustment Knob, in the clock-
wise direction. If the clamp leaves impressions or dam-
ages the string, it may be excessively tight and should be
adjusted by turning the knob counter clockwise to open
the gap between the jaws. The clamp jaws should be cleaned periodically to be free from dirt,
oil, and any string coating for them to grip properly.
Note: The string clamps supplied with your Gamma stringing machine can accomodate tight
stringpatternssuch asbadminton.Dependingon thestringpattern,the clampmayspreadthe
strings slightly which will not compromise the quality of the string job.

Step 1
After stringing many racquets, the brake of
the tensioner may need to be adjusted. The
Brake Adjustment Bolt can be accessed
through the hole in the face of the tensioner
cover, which does not need to be removed
for adjustment. The Tensioner Cover has
been removed in the pictures for illustration
purposes.
Step 2
With the brake lever engaged, loosen the
lowerhexboltlocatedonthebacksideofthe
tensioner frame with the 4 mm allen wrench.
Note: The hex bolt should only be loosened
until loose enough to turned by hand and
must not be removed completely.

PATHFINDERAWLOPERATION
The machine includes the Pathfinder string-
ing awl which creates a pathway between
or around strings and through tight grom-
mets.
Insert the awl through the grommet hole in
thesame mannerasfor traditionalawls.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.
