UsingtheM6openendwrenchpositionedon
the flat surfaces, securely tighten the rod to
the lower column.
The string reel holder can hold up to 5 reels
of string (depending on the size of the string
reel). Before placing the first reel on the rod,
slide two M8 washers over the pin and slide
them to the boss on the lower column. After
thefirst reelisplaced ontothe rod,placetwo
spacers between each reel to provide
enough space between reels and allow
them to turn freely without rubbing against
one another. (To provide a smooth feed to
the String Length Meter, place the reels on
the rod so the string spools off the reel from
the underside of the reel.)
After the last reel is installed, place the
remaining spacer(s) on the rod and attach
the threaded knob to the end of the rod.

STRING CLAMPS
StringClampOperation
The string clamps are a dual action design
where the string clamp 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 string clamp lever to secure the
string.The clampingpressure appliedtothe
string should be adjusted as needed (see
Page 18) to provide sufficient pressure to
secure the string when subjected to the
desiredpullingtension.Thediamondcoated
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.
MOUNTING THE FRAME
MountingStandAdjustment
Position the racquet frame over the mount-
ing stands and adjust the spacing between
thestands sothe postsof theframesupport
slides fit inside the head of the racquet. By
turning one of the knobs located at either
end of the turntable counter clockwise the
the stands move closer together. Turning
clockwise will increase the separation be-
tween the stands. With the stands posi-
tioned so the posts of the frame support
slides are completely within the head of the
racquet frame, turn one of the knobs clockwise until they contact the inside of the racquet
head at 6 and 12 o’clock.
Clamp Base Operation
Rotate the base locking lever clockwise to
secure the clamp base to the turntable and
counter clockwise unlock the string clamp.
The locking lever is spring loaded to assist
the unlocking of the clamp base.
The locking lever should be adjusted to
prevent clamp base slippage on the turn-
table, when the desired tension is placed on
thestring,whilepermittingtheclampbaseto
slide freely on the turntable when the lever
is disengaged.
Instructions for adjustment of the clamp base locking lever can be found on Page 17.

MOUNTING THE FRAME
ShoulderSupportAdjustment
The shoulder supports are designed to ro-
tateandcanbeadjustedtoprovidemaximum
support to the racquet frame. Rotate the
support so that the pads contact the frame
squarely when the arms are closed against
the racquet. Should the shoulder supports
block string holes, adjust the frame support

SecuringtheShoulder Supports
To secure the racquet frame with the shoul-
der supports, rotate the large adjustment
knobsonthe outsideof themounting stands
clockwise to bring the mounting arms to-
gether. Adjust until firm contact is made
between the shoulder 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 slidethestring intothepoint ofthe

FrameSupportSlideAdjustment
The Frame Support Slide need only be adjusted
if the shoulder supports are blocking a
grommet hole. Do not extend the Frame
Support Slide beyond the machined line located
on the Support Slide.
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 re-
adjusted, as needed, to maintain contact with
the racquet frame.

13
PullingTension
To apply tension, wrap the string being
tensioned clockwise around the roller guide
and position the string between the gripper
jaws.
The string must pass over the roller guide
before being placed between the gripper
jaws to ensure that the proper tension is
applied to the string.
Pullthestringuntilallslackisremovedbefore
pressing the tension lever switch.
STRINGING THE FRAME
Getting Started
To begin installing 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.
WARNING: KEEP FINGERSAWAY FROM ROLLER
GUIDE WHILE TENSIONING STRING. TO RELEASE
TENSION BEING APPLIED TO THE STRING PRESS THE
PUSH TENSION LEVER SWITCH OR ANY BUTTON ON
THE KEYPAD IN CASE OF EMERGENCY.
To apply tension to a string, press the
tension lever switch or the foot pedal
switch. The string gripper will move to the
right, away from the racquet, and gradu-
ally apply tension to the string. When the
set tension has been attained, the gripper
will stop moving. As the tensioned string
relaxes, the gripper will continue to pull
intermittently, to maintain the set tension.
Toreleasethe stringafterclamping,press
the tension lever switch or foot pedal
switch. If the string gripper does not re-
lease the string, push the gripper plates to
the right to help disengage and release the string from the gripper.

Clamping the First Main String
Secure the tensioned main string using the
remaining fixed clamp. Repeat the proce-
dureforalloftheremainingmainstringsand
tie off following the racquet manufacturers
recommendations.
Follow the manufacturer's recommended
stringing pattern for one or two piece string-
ing. This will determine the starting point for
the cross strings. If applicable, tie the first
cross string using an appropriate starting
knot.
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.
CompletingtheStringJob
Once the final cross string is tensioned and
clamped, tie off at the appropriate hole
specified by the racquet manufacturer.
Remove the frame from the mounting sys-
tem by loosening the shoulder supports and
frame supports.

TensionCalibrationProcedure
Each stringing machine has been
checked and calibrated at the factory
using accurate load sensing devices
toensurethat themachine pullsat the
correct tension. However, if you sus-
pect that your machine may not be
pulling at the correct tension you can
check the pulling tension with a cali-
bratorandmakeadjustmentsifneeded.
Most tension calibrators (such as a Gamma Tension Calibrator) function by clamping off the
string attached to one the end of the calibrator and applying tension to the string located
ontheoppositeendofthecalibrator.Thetensionmeasuredbythecalibratorwillthendisplay
the tension being applied to the calibrator by the machine. If the calibrator and tensioner
do not match then you can adjust the tensioner as follows:
(1) Turn the machine off and restart the machine while holding down the Test buttonuntil
count down is complete. 22 lbs should appear on the display. (2) Apply tension to the
calibrator. (3) If the tension reading on the calibrator does not match the tension displayed
onthemachine,usethetensionindexingbuttonstomatchthedisplaytothecalibratorreading

MAINTENANCE & ADJUSTMENTS
AdjustingtheString Clamp JawSpacing
The string 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
adjustedby turningtheAdjustment Knobcounterclockwisetoopenthegap betweenthejaws.
The clamp jaws should be cleaned periodically to be free from dirt, oil, and any string coating
for them to grip properly. Knife sharpening stones are excellent for removing build-up on the
diamond coated surfaces and are provided with the machine. Replacements are available.
Note: The string clamps supplied with your stringing machine can accomodate tight string
patternssuchasbadminton.Dependingonthestringpattern,theclampmayspreadthestrings
slightly which will not compromise the quality of the string job. String clamps designed
specifically for badminton racquets are included with the machine.
