MOUNTING THE FRAME
Adjusting the Frame Support Posts
Place the racquet frame over the center posts 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
theinsidesurface oftheracquetframe. Securelytighten
the lever lock bolt.
Adjust the opposite post using the same procedure.
Caution: To avoid racquet damage, the center posts
should not contact the racquet prior to fixing the support
posts.
Adjusting the Frame Shoulder Supports
Being sure the shoulder supports are free to swivel in
thier mountings, simultaneously rotate the shoulder
support adjustment knobs clockwise until both shoulder
supports gently and squarely contact the frame.
TightentheFrameSupportSlidesattheheadandthroat
of the racquet until they gently contact the frame be-
tween the two center main string grommets.
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-tightenallof theframe supports inthe sameorderas
before.
Do not overtighten any of the supports as racquet
damage may occur.
The supports should be tightened to the point where the
racquet frame will not move in the mounting system
when the handle is grasped and attempts are made to
moveit.Shouldany supportslosecontactwiththeframe
while stringing, they should be re-tightened.

Setting Tension
TheGAMMA 5003 utilizes a rotary adjusting knob along
withalinear tension scaletoindicate the tensionsetting.
The scale is divided into 3 lb increments and each 1/3
turn of the tension knob changes tension by 1 lb. To set
thedesiredtension,rotatethetensionknobandalignthe
markonthespringguidewiththedesired 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 counterclockwise 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.
STRINGING THE FRAME
Tensioner Travel Stop
To prevent contact between the tension head and the
racquet and/or turntable, a stop screw is located about
midpointalongthe tensioner barbelow the geartrack. In
the event the tension head must be moved closer to the
racquet, turn the stop screw counter-clockwise with the
5 mm hex wrench until the end of the stop screw no
longer protrudes beyond the surface of the tensioner
bar. To re-engage the stop, simply turn the stop screw
clockwiseuntil the screwis seated againstthe tensioner
bar.
Travel Stop
Clamp Head Operation
GAMMA “Quick Action” Clamps are of a dual action
design where as the clamp head and clamp base
operate independently of one another.
Toclampastring,lifttheclampheadandplacethestring
between the jaws and depress the clamp head lever to
secure the string. The clamping pressure applied to the
string should be adjusted to provide sufficient pressure
tosecurethestringwhensubjectedtothedesiredpulling
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
STRINGING THE FRAME
Pulling Tension
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 perpendicu-
lartothegripperplateswhileslowlyrotatingthetensioner
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 in-
stalled. Tie off ends of main strings as per racquet
manufacturers recommendations.
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 appro-
priate end of the frame and continue through the oppo-
site 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 the string
clamp. The Locking Lever is spring loaded to assist the
unlocking of the clamp base.
The Locking Lever should be tightened enough to pre-
vent 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, gener-
allyrequirestherotationpermitted by theslotinth clamp
base. If the rotation is not sufficient to allow smooth
operation of, adjust the Clamp Base Locking Nut as
outlined below.
Note:Ifthestringslipsinthestringclampwhiletensioning,
adjust the gap between the clamp jaws as per the
following instructions.

STRINGING THE FRAME
Weaving the Cross Strings
Weavethecrossstringsoverandunderthemainstrings
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 specified by the racquet
manufacturer.
11
Adjusting the Clamp Base Locking Nut
In the event the Locking Lever rotation is innsufficient to
ensure smooth operation of the clamp base, very minor
adjustments to the Clamp Base Locking Nut can be
madewiththesupplied17mmwrench.Tightenorloosen
the locking nut in very small increments to provide more
clamping pressure 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.
To adjust the gap (clamping pressure) between the
clampjaws,insertthestringthroughtheracquetasifyou
were beginning the main strings. Clamp the strings and
pull tension. If the string slips through the jaws of the
clamp, tighten the clamp by compressing the clamp
jaws together by hand while turning the Adjustment
Knob, in the clockwise direction. If the clamp leaves
impressions or damages the string, it may be exces-
sively tight and should be adjusted by turning the hex
screw 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 string patterns such as
badminton. Depending on the string pattern, the clamp may spread the strings slightly which will not compromise the
quality of the string job.

Step 2
Loosen the 1.5 mm locking set screw (A) located on the
side of the latching block as shown. The set screw is
used to hold the adjustment screw in place.
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 increase the engagement of the brake
release latch with the brake lever. Repeat step 1 and
adjustuntilthecorrecttensionisindicatedonthecalibra-
tor.
If the tension indicated in step 1 is greater than 60 lbs.,
turn the adjustment screw clockwise 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.

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.

Step 1
Afterstringingmanyracquets, the brakeofthetensioner
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 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
looseneduntil loose enoughto turnedby hand andmust
not be removed completely.

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 turn. Re-
tighten 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.

With time and use, the clamping surfaces of your machine may become oily or dirty and result in string or clamp
slippage while stringing. Periodic cleaning of the following parts is recommended.
String Clamps
Cleanthe insidegripping surfaces of the string clamp jaws by inserting a cloth or pipe cleaner soaked with isopropyl
alcohol between the jaws and rub back and forth. If the build-up is excessive, dismantle the string clamp jaws to
expose the gripping surfaces by removing the adjustment screw. Using a small nylon brush (such as a toothbrush),
a flat sharpening stone, or an ermery board, scrub the inside surfaces until all debris is removed. Clean the jaws
with isopropyl alcohol and re-assemble.
String Clamp Base
Clean the base of the clamps and the top of the turntable with isopropyl alcohol.
String Gripper
Clean inner gripping surfaces with isopropyl acohol soaked cloth or pipe cleaner. In cases where there is a lot of
build-up, use a flat emery board and scrub the surfaces first.
