tion as shown while turning the 5mm stop
screwlocatedonthebacksideof the winder
stand clockwise.
Winder Support Stand Installation
Remove the M5 bolts from the 2 brackets
locatedintherear slots of themachinebase
using the 5MM hex key. Slide the brackets
to the right end of the base and position the

of the turntable. While holding the mounting
plate against the inside top surface of the
turntable with your fingers, align the hole in
thesupportpostwiththeholeinthemounting
plate. Install the mounting bolt through the
support post and into the plate by hand and

MOUNTING THE FRAME
Tightening the Frame Supports
Tighten the Frame Support Slides by turn-
ing the adjustment knob clockwise until
snug against the racquet frame and slight
resistance is felt.
Caution: Overtightening the Center Sup-
portswill stretchtheheadoftheracquetand
could cause racquet damage.
Frame Shoulder Support Arm
Adjustment
Being sure the shoulder supports are free
to swivel in their mountings, simultaneously
rotatetheshouldersupportadjustmentknobs

and squarely contact the frame.
Adjusting the Frame Support Posts
Loosen the lock bolts of the frame support
posts and space them apart with the frame
supportslidesseparatedbytheapproximate
lengthof the racquet head.Although it is not
required,itisgoodpracticetocenterthesup-
port posts on the turntable. Lock one of the

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.

7
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.

wheretheracquetframewillnotmoveinthe
mounting system when the handle is grasped and attempts are made to move it. Should any
supports lose contact with the frame while stringing they should be re-tightened.

Note: An optional badminton frame support
for the head of the racquet is available.

and can be adjusted to provide maximum
support to the racquet frame. Rotate the
support so that the pads contact the frame
squarely when the arms are closed against
the racquet.

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.
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
the excess by hand. Using a floating clamp,
secure the center and the adjacent string to
each other on the inside of the frame.

9
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.
When the correct tension is attained, the
drop weight bar will rest horizontally as
shown. For accurate tensioning, it must
be lowered and come to rest at horizontal
without assistance. Manually forcing the
tension bar to the horizontal position will
greatly increase the 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.

STRINGING THE FRAME
Clamping the String
Clamp the tensioned string to the next ad-
jacent string using the second string clamp.
Releasethestringfromthegripperbyraising
the tension arm.
Repeattheprocedureforalloftheremaining
main strings and tie off following the racquet
manufacturers recommendations.
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 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.

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
automatically 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

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 hex wrench.
Tighten until the turntable rotates smoothly
without excessive free play.
Adjustment
Knob
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.
PROBLEM SOLUTION
String slips in clamps - Adjust gap between clamp jaws
- Clean clamp jaws
String slips in gripper - Clean gripper jaws
- Make sure string is wrapped over top gripper
prior to inserting between gripper jaws
