Inserttheturntablecenterpostintothebush-
ing assembly of the machine base.
Installing the Support posts
Slide each support post onto the end of the
turntable bar. The posts should be oriented so
astoangleawayfromtheturntablecenterpost.
Installing the Drop Weight
Remove the endcap from the tension bar
and slide the drop weight onto the bar. The
weight should be oriented with the knob end
closest to the string winder. Replace the
endcap.

ASSEMBLYINSTRUCTIONS
Clamp Adjustment
The floating clamps provided with your ma-
chinewillneedminoradjustmentsaccording
to what string type, construction, and gauge
you are using.
If the strings slip through the jaws of the
clamp, tighten the clamp by turning the
thumb knob opposite of the handle, in the
clockwise direction. If the clamps leave im-
pressions or damage the string, they are too
tight and the thumbwheel must be turned
counterclockwise.
The clamp jaws must be clean and free from
dirt, oil, and any string coating for them to
grip properly. Keep the clamp jaws clean
with alcohol.
Clamp Adjustment
Thumb Knob
Tension Bar Stop Screw
Raise the Tension Bar to an upright position.
Using the supplied 5MM wrench, securely
tighten the Stop Screw. This will prevent the
Tensionbarfromcontactingtheracquetframe.
Winder Support Stand Installation
Attach the winder support stand to the ma-
chine base using the 5MM hex key (in-
cluded) by sliding the 2 brackets into the 2
rear most grooves. Then align the right side
of the stand with the right end of the base.

MOUNTINGTHERACQUET
Installing the Racquet Support Adapters
The GAMMA X-2 is supplied with two styles
of RacquetSupportAdapters.Athickprofile
adapter for widebody racquets and a thin
profile adapter for conventional racquet
frames. The Adapters are also tapered, use
the highest side of the adapter that does not
interfere with the string grommet holes.
Adjusting the Frame Support Posts
Place the racquet frame over the center
posts and onto the frame support posts.
Loosen the locking screws on one support
post and slide the post in the appropriate
direction until the plastic adapter contacts
the frame. Securely tighten the locking
screws.Adjustthe oppositepostinthesame
manner.
It is extremely important both plastic adapt-
ers are in contact with the frame to prevent
racquet damage.
Securing the Racquet
With the frame support posts properly ad-
justed, place the frame hold down plates
overthecenterscrewsandtightentheclamp
bar knobs securely. Do not overtighten the
knobs as frame damage may occur.
Note: Inverted throat racquet frames may
require the throat clamp plate to be rotated
180 degrees to match the frame.

STRINGINGTHEFRAME
Setting Tension
The drop weight is of a two piece design.
When assembled, it will accomodate ten-
sionsfrom20lbs.to90lbs.Fortensionsfrom
8to20 lbs.,removethe5mmbolt ontheface
of the drop weight, and use the smaller
portion of the weight as described above.
Note: Tensions above 77lbs. require re-
moval of the drop weight bar endcap.
To set the stringing tension, loosen the lock-
ingknobon the sideofthedropweight.Slide
the weight in the appropriate direction until
the face closest to the string gripper is
indexedwiththedesiredtensionmarkonthe
tension bar.
Starting the Main Strings
Tobeginstringingthemainstrings,countthe
number of holes at the throat of the frame,
which will determine the starting point. For
racquets with 4 or 8 holes at the throat, the
main strings will begin at the head. For
racquets with 2 or 6 holes at the throat, the
main strings will begin at the throat.
Threadthetwoendsofthestringthroughthe
two center grommet holes at the head or
throat as determined in the previous step.
Route the strings through the opposite center holes.

6
STRINGINGTHEFRAME
Clamping the First Main String
Thread one end of the string through the
adjacent grommet hole and pull excess by
hand. Clamp both the center and the adja-
cent string to each other on the inside of the
frame.
Pulling Tension
Wrap the free string clockwise around the
gripper drum once and position between the
gripper jaw.
Gently turn the gripper clockwise while
squeezing the jaws together until all slack in
the string is removed.
Note:Forproperoperation,thestringgripper
jaw must be in the position shown. The
tension in the string provides the clamping
force to the jaws.
While holding the string gripper drum with
your hand, lift the tension bar to approx. 45
degree angle and let fall. If the tension bar
drops below horizontal, repeat the above
action until the bar comes to rest parallel to
the racquet. The set tension will be reached
when the bar rests horizontal.
If the bar comes to rest above horizontal,
release the string and re-pull tension.
Manually forcing the bar into the horizontal
position will greatly increase string tension
and may result in racquet damage.

7
STRINGINGTHEFRAME
Clamping the String
Clamp the tensioned string to the next adja-
cent string using the secong string clamp.
Release the tensioned string by raising the
tension arm.
Repeattheprocedureforalloftheremaining
main strings and tie off following the racquet
manufacturers recommendations.
Starting the Cross Strings
Follow the manufacturer's recommended
stringing pattern for one or two piece string-
ing. This will determine the starting point for
the cross strings. Weave the first two cross
strings and pull tension and clamp the cross
strings to each other.
Finishing the String Job
Weave and tension the remaining cross
strings and tie off at the specified grommet
hole.
RemovethestrungracquetfromtheGAMMA
X-2 in the reverse order of mounting.

PATHFINDERAWL
The GAMMA X-2 includes the Pathfinder
stringing awl which creates a pathway be-
tween or around strings to make inserting a
string through tight grommets easier and
quicker.
Insert the awl through the grommet hole in
the same manner as for traditional awls.
The Pathfinder awl must be in the closed
position before insertion.
Once the awl is inserted, pull the handle of
theawloutwardwhile 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.
