ASSEMBLY INSTRUCTIONS
Floor Stand Assembly
The stringing machine uses a four leg
fl oor stand design. The legs must be assembled to the lower column before use.
Remove all parts from the shipping carton
to confi rm that contents match the list of
parts on Page 5.
Floor Stand Leg Assembly
Align the holes in the leg fl ange with
the matching holes in the lower column.
Secure the leg with one M8 FLAT HEAD
screw through the upper hole, and one
M8 SOCKET HEAD cap screw through
the bottom hole. Install one 8mm nut on
each screw. Repeat this procedure for the
three remaining legs.
Floor Stand Assembly (Continued.)
To complete the fl oor stand, screw the height adjustment locking knob (“A”) into the side of the lower
column. The locking knob should not protrude beyond
the inside surface of the lower column at this time.
6
ASSEMBLY INSTRUCTIONS
Height Adjustment
The height of the machine is adjustable
from 39” to 46” in approximate 1” increments. To change the height, remove the
socket head cap screw from its current position and place it in the appropriate hole
to set the desired height of the machine.
Be sure to thread the screw completely
into the upper column so the head of the
cap screw rests in the notch of the lower
column that is parallel to the string reel
holder.
Stand Upper Post Installation
With the height adjustment cap screw on
the upper column facing the string reel
holder, align the four holes in the upper
column fl ange with the threaded holes in
the machine base. Lift the machine base
and insert the upper post into the lower
column until the head of the cap screw
rests in the notch of the lower column and
tighten the locking knob.
Remove this Screw
Transportation Screw
The machine has been shipped with a motor
and load cell protection screw. Remove the
screw before using the machine. Retain the
screw for future shipment. Install the included
rubber grommet into the hole.

ASSEMBLY INSTRUCTIONS
Turntable and Mounting System
Installation
To install the turntable position the turntable
over the turntable pin and align the bolts,
located in the poly bag, with the holes in
the fl ange. Secure them with the included
allen wrench.
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.
String Length Meter Wire Installation
Connect the black string length meter wire
to the receptacle in the black FRP base and
to the back of the tensioner.
8
STRING REEL HOLDER INSTALLATION
The string reel holder is an 8 mm rod with
threads on both ends, and fl at surfaces
machined on one end. Thread the end of
the rod without the fl at surfaces into the
threaded boss on the side of the lower
column. Using the M6 open end wrench
positioned on the fl at 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 fi rst reel
on the rod, slide two M8 washers over the
pin and slide them to the boss on the lower
column. After the fi rst reel is placed onto
the 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 rod and attach
the threaded knob to the end of the rod.

MOUNTING THE FRAME
Adjusting the Inner Racquet Supports
The white racquet supports are adjustable to accommodate
all racquets and provide maximum support to the racquet
frame. Screw the pads up or down so they contact the frame
at a maximum height without blocking the grommet holes.
Mounting Stand Adjustment
When mounting a racquet, adjust the
Mounting Stands so that the white Racquet
Supports on top of the Mounting Stands fi t
inside the hoop of the racquet. Lower the
racquet over the Racquet Supports and adjust the Mounting Stands until the supports
just make contact with the inside surface of
the racquet at the head and throat. There is
an arrow on the face of each knob indicating the turning direction that will “Tighten”
the mounting points by moving the 2pt
Racquet Supports closer to the inside surface of the racquet at the head and throat. Turning
the knobs in the opposite direction will move the Mounting Stands closer together and will
allow the Racquet Supports to move away from the racquet frame.
Mounting Stands further apart to bring the
Racquet Hold Down Clamp Operation
With the lever in the up position, insert the racquet hold
down clamp pin into the hole in the center of the mounting stand. Lower the hold down clamp until it just makes
contact with the surface of the racquet. Using slight palm
pressure on the hold down clamp depress the racquet
hold down lever completely to secure the racquet frame
to the stand.
12
MOUNTING THE FRAME
Special Throat Mounting
For racquets with a bridge that is thinner than
the rest of the frame or are tapered from head
to throat you may need to mount the racquet
with the shafts of the racquets supported by
the white support pads as pictured.
BRIDGE
STRINGING THE FRAME
String Clamp Operation
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 string clamp, 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 to provide suffi cient pressure to secure the string when subjected to
the desired pulling tension. The diamond
coated gripper plates provide for increased
to allow for reduced clamping pressure while securing and holding the string under tension.
Note that excessive pressure can damage both the strings and String Clamp.
friction between the clamps and the string
Clamp Base Operation
To lock the string clamp base to the turntable,
rotate the clamp base locking lever clockwise.
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.
13
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.
Handy tip: The tear drop shaped holes
are handy for holding the loose end of the string while tensioning the string. Simply insert the
loose end into the tear drop shaped holes and slide the string toward the point of the hole.
Aramid fi ber and metallic strings will generally string up tighter on the machine compared
to synthetic or natural gut strings. Therefore, when stringing with Aramid (Kevlar, Technora)
hybrid strings or metallic strings, we recommend setting tension 4-5 lbs. lower than you would
normally use for synthetic or natural gut strings.
towards the back of the shoulder supports
Setting the 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 keypad or the tension index buttons.
While a tension setting is entered, the value
displayed will be temporary until the “Enter”
button is pressed to store it in one of the nine
permanent memory settings.
Applying Tension
To apply tension, wrap the string clockwise
around the gripper drum and position the
string between the gripper jaws.
The string must pass over the upper gripper
jaw before being placed between the gripper
jaws, as the tension on the string provides the
clamping force to the gripper jaws.
Before applying tension, gently pull the string
until all slack is removed.
CAUTION: NEVER TENSION A STRING WITH YOUR FINGERS BETWEEN
THE STRING AND THE UPPER GRIPPER JAW AS SERIOUS INJURY COULD
RESULT IF YOUR FINGER IS CAUGHT BETWEEN THE STRING AND THE
UPPER JAW DURING TENSIONING.
SWITCH OR ANY BUTTON IN CASE OF EMERGENCY.
PUSH GRIPPER REVERSING
14
STRINGING THE FRAME
To apply tension to a string, push the tension
switch or the foot pedal. The string gripper will
rotate and slowly apply tension to the string.
When the set tension has been attained,
the gripper will stop rotating and the display
will fl ash. As the tensioned string stretches,
the gripper will continue to pull and rotate
intermittently, maintaining the set tension.
To release the string after clamping, push the
tension switch or foot pedal. If the string gripper does not release the string, depress and
hold the return button to release the string.
Clamping the First Main String
Secure the tensioned main string using the
free fi xed clamp. Repeat the procedure for
all of the remaining main strings and tie off
following the racquet manufacturers recommendations.
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.
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.
15
STRINGING THE FRAME
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 releasing
the racquet holddowns and loosening the
mounting stands.
ADDITIONAL FEATURES
Locking the Turntable
The turntable may be locked in any position.
Rotate the lever down to lock the turntable
and up to release the turntable.
16
STRING LENGTH METER OPERATION
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 SLM function is enabled. Pressing the String 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
SLM Button
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
string guide attached to the front of the
SLM. Lift the clamp pad and insert the
string through the entry hole on the face
plate of the SLM. Continue to feed the
string into the entry hole until it exits the
SLM through the hole on the right side
and release the clamp pad. (In addition to
aligning the strings with the entry to the
SLM, the felt clamp pads apply a slight
amount of pressure to the string and wipe
down the surface of the string to prevent
debris from entering the SLM).
When the end of the string exits through
the hole on the right, press the “C” or “Enter/
Clear” button on the keypad to “Zero” the
display. The length of string will be measured from the free end to the edge of the
exit hole. Pull the free end of the string at
a slow steady rate and the SLM will begin
measuring the length of string as it is pulled
through the SLM and indicate the measurement on the LED display. When the desired
length of string is measured, cut the string
at the edge of the exit hole.
Note: When reaching the end of a string, pull the string through the SLM slowly unit
it exits the SLM to avoid inaccurate measurement.
The string length meter was designed to measure strings between 1.10 mm (18 ga) and
1.45 mm (15 ga) at an accuracy of +/- 0.3% of the indicated value and +/- 2 inches (50 mm)
absolute. When measuring strings smaller than 1.10 mm (such as badminton strings) the
error will be -2.5% of the indicated value (up to 6” short in 40 ft) and +/- 2 inches (50 mm)
absolute.
17
PATHFINDER AWL
The machine includes the Pathfi nder stringing 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.
18
MAINTENANCE & ADJUSTMENTS
Tension Calibration Procedure
Each stringing machine has been checked and
calibrated at the factory using accurate load sensing devices to ensure that the machine pulls at the
correct tension. However, if you suspect that your
machine may not be pulling at the correct tension
you can check the pulling tension with a calibrator
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 on
the opposite end of the calibrator. The tension measured by the calibrator will then display
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 button until
the 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 on
the machine, use the tension indexing buttons to match the display to the calibrator reading
and press the Enter/Clear button (4) Release the tension applied to the calibrator and 44 lbs
should appear on the display. (5) Repeat steps #2-#4 for 44, 66 & 88lbs. (6) After completing
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.
Switching the Buzzer Off and On
The stringing machine is equipped with a buzzer that sounds when any key or button is
pressed or when there is a problem with some function of the machine. The buzzer can 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 a problem and the
machine requires attention. This is meant to alert the user of a problem, and can not be
disabled.
19
MAINTENANCE & ADJUSTMENTS
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 and
a hex wrench as a lever. Tighten or loosen
the locking nut in very small increments to
provide more clamping pressure or running
clearance as needed.
Quick Action Clamp Base Removal
Quick Action clamp bases can be removed
from the turntable for maintenance or cleaning by removing clamp stop located at the
end of the slot in the turntable. To remove the
clamp stop, remove the two screws holding
the clamp stop in place from the underside of
the turntable. Lift the clamp stop out of the
slot, slide the clamp base to the end of the
slot and lift it out. Replace the clamp base
and clamp stop in reverse order.
Adjusting the String Clamp Jaw
Spacing
The string clamps will need minor adjustments according to what string type, construction, and gauge you are using.
To adjust the gap (clamping pressure)
between the clamp jaws, insert the string
Adjustment
Knob
or damages the string, it may be excessively tight and should be adjusted by turning the
Adjustment Knob counter clockwise to open the gap between the jaws.
NOTE: Due to the bearings used in the Clamp Lever the action of the Clamp Lever is
very light making it easy to apply excessive clamping pressure. Clamps that are set
too tight can damage the string as well as the string clamp jaws.
The clamp jaws should be cleaned periodically to be free from dirt, oil, and any string coating
residue to grip properly. Knife sharpening stones are excellent for removing build-up on the
diamond coated surfaces and are available.
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, tighten the clamp by squeezing
the clamp jaws together by hand while turning the Adjustment Knob, in the clockwise
direction. If the clamp leaves impressions

MAINTENANCE & ADJUSTMENTS
2pt Hold Down Clamp Adjustment
The 2pt hold down clamps have been adjusted at
the factory. However, depending on the racquet
frame thickness, the hold down clamp may require
adjustment. Use a 3 mm hex wrench and turn the
set screw clockwise to reduce the hold down clamp
pressure and counter clockwise to increase the hold
down clamp pressure.
Note: To avoid potential damage to the racquet only
make small adjustments at a time by slightly turning
the set screw by no more than 1/4 of a turn. Test
snuggly but without applying excessive force to the lever.
Periodically clean the hold down clamp pin using rubbing alcohol to remove residue or dirt,
that may build up over time.
the hold down lever to insure the racquet is held
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
Electrical system does not function - Check power source
- Check power cord connections
String tension too tight or too loose - Check tension using a tension calibrator,
adjust machine calibration if necessary
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, String Clamp
Base 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.
