ASSEMBLY INSTRUCTIONS
String Clamp Installation
The post of the string clamp 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.

Note: An optional badminton frame support
for the head of the racquet is available.
STRINGING THE FRAME
The drop weight is of a two piece design.
When assembled, it will accommodate ten-
sions from 20 to 90 lbs For tensions from 8
to20lbs,removethe5mmboltonthefaceof
the drop weight, and use the smaller portion
of the weight as described above.
Note: Tensions above 77lbs require the
removal of the drop weight bar end cap.
Setting Tension
To set the stringing tension, loosen the
locking knob on the side of the drop weight.
Slide the weight in the appropriate direction
until the face closest to the string gripper
is indexed with the desired tension mark on
the tension bar.

10
STRINGING THE FRAME
Base Clamp Operation
Rotate the lever lock clockwise to secure
the clamp base to the turntable.
Reverse the clamping procedure to unlock
the string clamp.
The lever should be tightened enough to
prevent clamp base slippage on the turn-
table, when the desired tension is placed
on the string. To go from the loose position
to the clamped position and back, gener-
ally requires about 1/2 to 3/4 quarters of a
turn. Although when stringing at extremely
high tensions, additional tightness may be required.
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.
String Clamp Operation
The fixed clamps are of a dual action de-
sign. 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 should be adjusted to provide
sufficient pressure to secure the string
when subjected to the desired pulling ten-
sion. 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.
Note: If the string slips in the string clamp while tensioning, adjust the gap between the
clamp jaws as per the instructions on page 15.

11
Gripping the String
While holding the tension bar slightly above
horizontal, 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: For proper operation, the string grip-
per jaw must be in the position shown. The
tension in the string provides the clamping
force to the jaws.
Pulling Tension
Whilesecurelyholdingthestringgripperdrum
with your hand, lift the tension bar above
horizontal and gently lower the bar under its
own weight. If the tension bar drops below
horizontal, repeat the above action until the
bar comes to rest parallel to the racquet.
Whenthecorrecttensionisattained,thedrop
weightbarwillresthorizontallyasshown. For
accurate tensioning, it must be lowered and
cometorestathorizontalwithoutassistance.
Manually forcing the tension bar to the hori-
zontalpositionwillgreatlyincreasethe string
tension and may result in racquet damage.
If the tension bar comes to rest above hori-
zontal, release the string by lifting the bar
and re-pull the string.
STRINGING THE FRAME
WARNING: TO AVOID INJURY, KEEP FINGERS AWAY
FROM GRIPPER JAWS WHILE TENSIONING STRING.

12
STRINGING THE FRAME
Weaving the Cross Strings
Follow the manufacturer's recommended
stringingpatternforoneortwopiecestringing.
This will determine the starting point for the
cross strings. If applicable, tie the first cross
string using an appropriate starting knot.
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.
Completing the String Job
Once the final cross string is tensioned and
clamped,tieoffattheappropriateholespeci-
fied by the racquet manufacturer.
Removetheframefromthemountingsystem
by loosening the shoulder supports and
frame supports.
Clamping the String
Secure the tensioned main string using
the remaining fixed clamp. Release the
string from the gripper by raising the ten-
sion arm.
Repeat the procedure for all of the remain-
ing main strings and tie off following the
racquet manufacturers recommendations.

13
Storage Drawers
There is one storage drawer located in the
baseofthemachine.Thedraweropensfrom
the right side of the base and lock into the
end cap with a spring loaded latch.
To open the drawer depress the latch in the
face of the drawer and slide it to the right.
To close the drawer simply slide the drawer
back inside the base and the latch with au-
tomatically lock into place.

PATHFINDER AWL
Once the awl is inserted, pull the handle of
the awl outward while holding the tip section
in place. This leaves the outer sheath in the
grommet hole. Insert the end of the string
into the outer sheath.
Whileholdingthestring,slowlypullthesheath
outofthegrommetholetoleavethefreeend
of the string exposed.
The machine includes the pathfinder string-
ing awl which creates a pathway between
or around strings to make inserting a string
through blocked grommets easier and
quicker.
Insert the awl through the grommet hole in
thesamemannerasfortraditionalawls.The
Pathfinderawlmustbeintheclosedposition
before insertion.

15
Adjusting the Clamps
The clamps provided with your stringing
machinewillneedminoradjustmentsaccord-
ing to string type, construction, and gauge.
Toadjust,routethestringthroughtheracquet
as if you 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 turning the adjustment
knoboppositeofthehandle,intheclockwise
direction.Iftheclamp leaves impressions or
damages the string, it is too tight and must
be adjusted by turning the adjustment knob
counterclockwise.
The clamp jaws must be clean and free from dirt, oil, and any string coating for them to grip
properly. Clean the clamp jaws with alcohol.
Note: The string clamps supplied with your stringing machine can accommodate tight string
patternssuchasbadminton.Depending on the string pattern,theclampwillspreadthestrings
slightly which will not compromise the quality of the string job.
MAINTENANCE & ADJUSTMENTS
Turntable Bushing Adjustment
The turntable bushing is adjusted at the fac-
toryforoptimumperformance.Aftertimeand
use, the turntable bushings may need minor
adjustment.Anadjustmentisindicatedwhen
noticeable turntable looseness or wobble
occurs while stringing.
To adjust the fit between the turntable pin
andthebushings,tightenthesetscrewatthe
topof the bushingusing a 3mm hexwrench.
Tighten until the turntable rotates smoothly
without excessive free play.

ClampBaseLockingNutAdjustment
In the event the Locking Lever rotation is
insufficienttoensuresmoothoperationofthe
clamp base, very minor adjustments to the
Clamp Base Locking Nut can be made with
thesupplied17mmsocket. Tightenorloosen
the locking nut in very small increments to
provide more clamping pressure or running
clearance as needed.

16
CARE & CLEANING
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 String Clamps and String
Gripper is recommended. Knife sharpening stones work well for cleaning the diamond coated
stringclampingsurfaces.Cleaningwithasolventsuchasisopropylalcoholandamildabrasive
tool such as a toothbrush also works well to remove oily or greasy build up.
TROUBLESHOOTING TIPS
PROBLEM SOLUTION
