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 reelis placedontothe rod,place two
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 pin and attach
the threaded knob to the end of the rod.

ASSEMBLY INSTRUCTIONS
StringClampInstallation
The post of the string clamp and tube of the
string clamp base are treated with grease to
provide protection against corrosion during
shipping and while in storage. Remove any
excessive grease with a clean cloth prior to
use.Thepost and tube may alsobe 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.
Turntable and Mounting System In-
stallation
To install the turntable remove the four nuts
underneath holding the mounting bolts in
place. Position the turntable over the turn-
table pin and align the bolts with the holes in
the flange. Secure them with the included
allen wrench.

Instructions for Power Connection and Controls

string reaches the tension setting, the LED
display will begin to flash, and the string will
be ready to clamp off. In the event that one of the keys on the control panel are accidently
pressed while tensioning a string, the tensioner will automatically reverse and release the
string being tensioned.
TENSIONER OPERATION
Settingthe String Tension
String tensions may be entered and stored
into one of nine memory storage settings
(See section on Control panel Functions
and features) by using the tension index
buttons. While tension setting is entered,
the value displayed will be temporary until
the “Enter” button is pressed to store it in

AdjustingtheFrame Support Posts
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
oftheposts in position bytighteningthe 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.

STRING CLAMPS
Clamp Base Operation
Tolockthestringclampbasetotheturntable,
rotate the clamp base locking lever clock-
wise. To release the string clamp base from
the turntable, rotate the clamp base locking
lever counter-clockwise.
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 th clamp base.
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
depress the string clamp lever to secure the
string. The clamping pressure applied to the
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

MOUNTING THE FRAME
FrameShoulderSupportAdjustment
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.
TighteningtheFrameSupports
Tightenthe Frame Support Slidesby turning
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.
12
SecuringtheFrameShoulderClamps
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
inthemounting system when the handleisgrasped and attempts are made tomove it. Should
any supports lose contact with the frame while stringing, they should be re-tightened.

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 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.
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 gradually
apply tension to the string. When the set
tension has been attained, the gripper will
stop moving. As the tensioned string re-
laxes, the gripper will continue to pull inter-
mittently, to maintain the set tension.
To release the string after clamping, press
thetensionleverswitchorfootpedalswitch.
If the string gripper does not release the string, push the gripper plates to the right to help
disengage and release the string from the gripper.

ClampingtheFirstMainString
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.

To enable the String Length Meter (SLM)
function, press the String Length button on
the keypad. When the String Length button
is pressed, one of the LED indicators above
“M” or “FT” will light up to indicate that the
SLMfunctionisenabled.Pressing theString
Length button will toggle between “M” and
“FT” to set the measurement units for either
Meters (“M”) or Feet (“FT”). Measurements
are displayed in 0.1 increments.
To measure a length of string from a reel or
set of string, insert the end of the string
through the loop from the backside of the
stringguide attached tothefront of theSLM.

MAINTENANCE &ADJUSTMENTS
Switching the Buzzer Off and On
The stringing machine is equipped with a buzzer that sounds when any key or button is
pressed,when the tensionerhaspulled a stringto the end ofits travel andis not yet attension,
or when there is a problem with the some fucntion of the machine. The buzzer can, however,
be disabled if desired for normal keypad entries.
To disable the buzzer, turn the machine on and while the display is counting down from 9 to
0, press and hold the Enter/Clear button for at least 5 seconds. The buzzer will be disabled
and will remain disabled. It can be enabled again by following the same steps listed above.
NOTE: Even when disabled, the buzzer will sound if the tensioner has pulled a string and
reached the end of the track prior to reaching the desired tension in the string, or if there is
some other problem with the machine that requires attention.This is meant to alert the user
of a problem, and can not be disabled.
AdjustingtheClampBase
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 a 17mm socket. Tighten or loosen the
locking nut in very small increments to pro-
vide more clamping pressure or running
clearance as needed.
TensionCalibrationProcedure
Each stringing machine has been checked
and calibrated at the factory using accu-
rate load sensing devices to ensure that
the machine pulls at the correct tension.
However, if you suspect that your machine
maynotbepullingatthecorrecttensionyou
cancheckthepullingtensionwithacalibra-
tor and make adjustments if needed.
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
and press the Enter/Clear button (4) Release the tension applied to the calibrator and 44 lbs
shouldappearonthe display.(5)Repeatsteps #2-#4for44,66 &88lbs. (6)Aftercompleting
the adjustment at 88lbs the display will show 00 lbs. (7) Restart the machine without holding
any buttons and the calibration adjustment will be complete.

MAINTENANCE &ADJUSTMENTS
Adjustingthe String Clamp Jaw Spacing
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
adjusted by turning the Adjustment Knob counter clock-
wise 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. Knife sharpening stones
are excellent for removing build-up on the diamond coated surfaces and 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 available.

QuickActionClamp Base Removal
Quick Action clamp bases can be removed
from the turntable for maintenance or clean-
ingbyremovingclampstoplocatedattheend
of the slot in the turntable. To remove the
clamp stop, remove the two screws holding
theclampstopinplacefromtheundersideof
the turntable. Lift the clamp stop out of the
slot,slidetheclampbasetotheendoftheslot
and lift it out. Replace the clamp base and
clamp stop in reverse order.
GripperPlateSpacingAdjustment
The parallel plates of the string gripper are
adjustable to accomodate varying string
gauges and types of string. If the string slips
through the gripper plates while pulling ten-
sion, rotate the gripper adjustment screw
counter-clockwise. If the string is damaged
while pulling tension, rotate the gripper ad-
justment screw clockwise. The gripper is
properly adjusted when there is enough
pressure to securely hold the string without
causing damage to the string. If you move
the gripper to the right hand end of the track
it is easier to access the screw.
