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 corrosion during shipping. Remove any excessive 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.
MOUNTING THE FRAME
Adjusting the Frame Support Posts
Loosen the lock bolts of the frame support
posts and space them apart with the frame
support slides separated by the approximate
length of the racquet head. Although it is not
required, it is good practice to center the support posts on the turntable. Lock one of the
posts in position by tightening the lock bolt and
position the other post until the frame support
slide is positioned near the inside surface of
the racquet frame. Securely tighten the lock
bolt of the second support post.
center posts should not contact the racquet prior to locking down the support posts.
Caution: To avoid racquet damage, the
Tightening the Frame Supports
Tighten the Frame Support Slides by turning the adjustment knob clockwise until
snug against the racquet frame and slight
resistance is felt.
Caution: Overtightening the Center Supports will stretch the head of the racquet and
could cause racquet damage.

MOUNTING THE FRAME
Frame Shoulder Support Arm
Adjustment
Being sure the shoulder supports are free
to swivel in their mountings, simultaneously
rotate the shoulder support adjustment knobs
clockwise until both shoulder supports gently
and squarely contact the frame.
Frame Shoulder Support Adjustment
The shoulder supports are designed to rotate
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.
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.
The supports should be tightened to the point
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.

Badminton Shoulder Support Protection Pad Installation
Slide the badminton shoulder support cover
over the shoulder supports. There is no need
to remove the tennis shoulder supports.
Note: An optional badminton frame support
for the head of the racquet is available.
STRINGING THE FRAME
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.
The drop weight is of a two piece design.
When assembled, it will accommodate tensions from 20 to 90 lbs For tensions from 8
to 20 lbs, remove the 5mm bolt on the face of
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.

STRINGING THE FRAME
String Clamp Operation
The fi xed 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
suffi cient pressure to secure the string
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.
high tensions, additional tightness may be required.
when subjected to the desired pulling ten-
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 turntable, when the desired tension is placed
on the string. To go from the loose position
to the clamped position and back, generally requires about 1/2 to 3/4 quarters of a
turn. Although when stringing at extremely
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.
10
STRINGING THE FRAME
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 gripper jaw must be in the position shown. The
tension in the string provides the clamping
force to the jaws.
Pulling Tension
While securely holding the string gripper drum
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.
WARNING: TO AVOID INJURY, KEEP FINGERS AWAY
FROM GRIPPER JAWS WHILE TENSIONING STRING.
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 horizontal, release the string by lifting the bar
and re-pull the string.
11
STRINGING THE FRAME
Clamping the String
Secure the tensioned main string using
the remaining fi xed clamp. Release the
string from the gripper by raising the tension arm.
Repeat the procedure for all of the remaining main strings and tie off following the
racquet manufacturers recommendations.
Weaving the Cross Strings
Follow the manufacturer's recommended
stringing pattern for one or two piece stringing.
This will determine the starting point for the
cross strings. If applicable, tie the fi rst 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 fi nal cross string is tensioned and
clamped, tie off at the appropriate hole specifi ed by the racquet manufacturer.
Remove the frame from the mounting system
by loosening the shoulder supports and
frame supports.

ADDITIONAL FEATURES
Storage Drawers
There is one storage drawer located in the
base of the machine. The drawer opens from
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.
13
P ATHFINDER A WL
The machine includes the pathfi nder 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
the same manner as for traditional awls. The
Pathfi nder awl must be in the closed position
before insertion.
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.
While holding the string, slowly pull the sheath
out of the grommet hole to leave the free end
of the string exposed.

MAINTENANCE & ADJUSTMENTS
Turntable Bushing Adjustment
The turntable bushing is adjusted at the factory for optimum performance. After time and
use, the turntable bushings may need minor
adjustment. An adjustment is indicated when
noticeable turntable looseness or wobble
occurs while stringing.
To adjust the fi t between the turntable pin
and the bushings, tighten the set screw at the
top of the bushing using a 3mm hex wrench.
Tighten until the turntable rotates smoothly
without excessive free play.
Adjusting the Clamps
The clamps provided with your stringing
machine will need minor adjustments according to string type, construction, and gauge.
T o adjust, route 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,
Adjustment
Knob
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.
tighten the clamp by turning the adjustment
knob opposite of the handle, in the clockwise
direction. If the clamp leaves impressions or
damages the string, it is too tight and must
be adjusted by turning the adjustment knob
counterclockwise.
Note: The string clamps supplied with your stringing machine can accommodate tight string
patterns such as badminton. Depending on the string pattern, the clamp will spread the strings
slightly which will not compromise the quality of the string job.
Clamp Base Locking Nut Adjustment
In the event the Locking Lever rotation is
insuffi cient to ensure smooth operation of the
clamp base, very minor adjustments to the
Clamp Base Locking Nut can be made with
the supplied 17mm socket. Tighten or loosen
the locking nut in very small increments to
provide more clamping pressure or running
clearance as needed.

TROUBLESHOOTING TIPS
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
String clamp base slips on turntable - Clean bottom of clamp & top of turntable with
alcohol
- Adjust clamp base locking nut
With time and use, the clamping surfaces of your machine may become oily or dirty and result
CARE & CLEANING
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
string clamping surfaces. Cleaning with a solvent such as isopropyl alcohol and a mild abrasive
tool such as a toothbrush also works well to remove oily or greasy build up.
