ASSEMBLY INSTRUCTIONS
Fixed Clamp Installation
To install the clamps, remove the winged
lock knob to separate the knob from the
lower guide bushing. Be careful not to lose
thethrustbearingcomponentslocatedinthe
center recess of the knob.
Align the clamp base with the clamp slot of
the turntable base. Insert the lower guide
bushing into the clamp from the bottom of
the turntable making sure to engage the
guide with the clamp slot.
Installing the Frame Support Posts
The GAMMA 5002 support post assemblies
are precision aligned at the factory and are
marked for proper installation on the turn-
table.
Install the support post with the dot on its
base to an identical dot on the turntable.
Align the threaded hole in the bottom of the
frame support post with the slot in the turn-
table. Screw the lever lock bolt with washer
into the bottom of the support post and
tighten gently.Position the washer with the
rounded edge toward the turntable. Repeat
procedure on the opposite side of the turntable.

ASSEMBLYINSTRUCTIONS
Locking the Turntable
The turntable may be locked in any position.
The turntable winged lock knob is packed
separately in the accessory polybag. 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.
Place the load bushing into the top of the
clamp base mating it to the lower guide
bushing. After checking that the thrust bear-
ing is positioned correctly in the base of the
winged lock knob, screw the knob into the
base bushing until fully seated.
The post of the string clamp head and tube
of the string clamp base are treated with
grease to provide protection against corro-
sion during shipping. Remove any exces-
sive 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.
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.

MOUNTING THE FRAME
Adjusting the Frame Support Posts
Place the racquet frame over the center
posts and onto the frame support. Loosen
theleverlock 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 cen-
terpostsshouldnotcontacttheracquetprior
to fixing the support posts.
Adjusting the Frame Shoulder Supports
Being sure the shoulder supports are free to
swivel in thier mountings, simultaneously
rotatetheshouldersupportadjustmentknobs
clockwiseuntilbothshouldersupportsgently
and squarely contact the frame.
Tighten the Frame Support Slides at the
head and throat of the racquet until they
gently contact the frame between 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-tighten all of the frame supports in the
same order as 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
inthe mounting system when the handle is grasped and attempts are madeto move it. Should
any supports lose contact with the frame while stringing, they should be re-tightened.

Setting Tension
TheGAMMA5002utilizesarotaryadjusting
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
withthedesired tension setting onthescale.
Whenthe“0”markontheknobalignswiththe
line on the knob support the tension will be
that indicated on the scale. To increase ten-
sionby 1or 2lbsturntheknobcounterclock-
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.
STRINGING THE FRAME
Fixed Clamp Operation - Step 1
ThefixedclampsfortheGAMMA5002areof
a dual action design. The string clamp and
the clamp base operate independently 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.
The clamping pressure applied to the string
shouldbeadjustedtoprovidesufficientpres-
sure to secure the string when subjected to
the desired pulling 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.
Tensioner Travel Stop
Topreventcontactbetweenthetensionhead
and the racquet and/or turntable, a stop
screw is located about midpoint along the
tensioner bar below the gear track. In the
eventthetensionheadmustbemovedcloser
to the racquet, turn the stop screw counter-
clockwisewiththe5mmhexwrenchuntilthe
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 clockwise until the screw is seated
against the tensioner bar.

STRINGING THE FRAME
Pulling Tension
Wrap theloosesectionofstringoncearound
theroller guideandinsertthestring 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.
Repeattheabovestepsuntilallmainstrings
are installed. Tie off ends of main strings as
per racquet manufacturers recommenda-
tions.
Fixed Clamp Operation - Step 2
Rotate the winged lock knob clockwise to
secure the clamp base to the turntable.
Reverse the clamping procedure to unlock
the string clamp.
The winged lock knob 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 about 1/2 to 3/4 quarters
of a turn. Although when stringing at ex-
tremely high tensions, additional tightness may be required. Note: If the string slips in the
string clamp while tensioning, adjust the gap between the clamp jaws as per the
instructions on page 11.
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.

10
STRINGING THE FRAME
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.

11
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
thesame mannerasfortraditionalawls. 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.

AAdjusting 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
leveronthe back side of thetensionerframe
using the 3 mm hex wrench. With the brake
lever released remove the cover.
Adjusting the Tensioner Brake
Step 2
Withthecover removed,andthe 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
thenutlocatedatthebaseofthebrakelever.
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
alongthetrack with thebrakeleverengaged
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.
