ASSEMBLY INSTRUCTIONS
Base Leg Assembly
The stringing machine uses a four leg base
design. The legs must be assembled to the
lower column support before use. This is the
larger of the two posts with the GAMMA label.
Note: For illustration purposes, the support
column has been painted white for these
instructions.
Align the holes in the leg ange with the
matching holes in the lower column support
post. Secure the leg with one FLAT HEAD
cap screw through the upper hole, and one
SOCKET HEAD cap screw through the bot-
tom hole. Repeat this procedure for the three
remaining legs.
Base Foot Height Adjustment
Each foot of the Base Stand can be adjusted
to compensate for uneven surfaces.
Upper Column Support Assembly
The upper column support is shipped inside
of the lower column support. Unloosen the
two set screws at the top of the lower column
support / base leg assembly. Extend the up-
per column to the maximum height and lock
in place with the two set screws located at
the top of the lower column support.
6
Bellows Installation
The bellows assembly is supplied in two
pieces and should be assembled as follows.
Place the bellows section with the ange over
the upper support column with the ange on
the top. Place the remaining bellows over
the upper support column and mate it with
the ange on the lower bellows.
Tool Tray Installation
Lower the tool tray over the top of the upper
column support and let it rest loosely on the
bellows assembly.
Tension Track Installation
Place the tube of the tension track assembly
over the top of the upper column support and
align the tension track with the long leg of the
base. Securely tighten the two socket set
screws on the tension track assembly tube,
locking it to the upper column support. Align
the notch in the tool tray with the tension
track bar while raising the tool tray. Secure
the tray with the set screws in the side of
the tray casting.

ASSEMBLY INSTRUCTIONS
Turntable and Mounting System
Installation
To install the turntable remove the four nuts
holding the mounting bolts in place during
shipment. Position the turntable over the
turntable pin and align the bolts with the
holes in the ange. Secure them with the
included allen wrench.
Caution: If the mounting bolts are removed
or fall out during assembly be sure that the
bolts pass through the spacer inside the
turntable before securing the turntable to
the turntable pin.
Installing the Tensioner
Remove the button head screw and washer
located at the end of the tensioner bar with
the 3mm hex wrench provided. Slide the
tensioner onto the bar, being careful to align
the bar with all of the bearings and the drive
gear with the gear track. Replace the button
head screw and washer in the end of the
tensioner bar.
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
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 Stand Adjustment
Position the racquet frame over the
mounting stands and adjust the spacing
between the stands so the posts of the
frame support slides t inside the head of
the racquet. By turning one of the knobs
located at either end of the turntable
counter clockwise the stands move closer
together. Turning clockwise will increase
the separation between the stands. With
the stands positioned so the posts of the
frame support slides are completely within
the head of the racquet frame, turn one of
the knobs clockwise until they contact the inside of the racquet head at 6 and 12 o’clock.
ASSEMBLY INSTRUCTIONS
Height Adjustment
The turntable height can be adjusted to suit
the stringer. To adjust, loosen the two set
screws on the lower column support post
below the bellows assembly. Adjust the
amount of engagement between the upper
and lower column supports until the desired
height is attained. Make sure that the tension
track is still aligned with the long leg of the
base and tighten the two set screws to lock
the upper support column into place.

MOUNTING THE FRAME
Adjusting the Frame Shoulder Sup-
ports
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.
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.
Caution: Do not overtighten any of the sup-
ports as racquet damage may occur.
The supports should be tightened to the point
where the racquet frame will not move in the
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 Protec-
tion 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.

String Clamp Operation
The string clamps are a dual action design
where the string clamp and clamp base oper-
ate 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 sufcient pressure
to secure the string when subjected to the
desired pulling tension. 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.
STRINGING THE FRAME
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.
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 turn-
table when the desired tension is placed on
the string.
