ASSEMBLY INSTRUCTIONS
Installing the Turntable
Remove the turntable from the foam packing of the
shipping carton. Insert the center post of the turntable
into the bushing of the stringing machine base.
Engaging the Drop Weight Bar Stop
The stringing machine is shipped with the drop weight
bar in the horizontal position. To prevent racquet
damageduringstringing,thebarstopmustbeengaged.
Remove the machine base from the shipping carton
being careful to avoid lifting by the plastic cover.
Holdthedropweightbarintheverticalpositionasshown
while turning the stop screw clockwise with the supplied
5mm hex wrench.
Installing the Frame Support Posts
The Progression 602 support post assemblies are pre-
cision aligned at the factory and are marked for proper
installation on the turntable.
Install the support post with the dot on its base to an
identical dot on the turntable. Align the threaded hole in
the bottom of the frame support post with the slot in the
turntable. Screw the lever lock bolt with washer into the
bottom of the support post and tighten gently.Position
the washer the rounded side toward the turntable.
Repeat procedure on the opposite side of the turntable

MOUNTING THE FRAME
Adjusting the Frame Support Posts
Place the racquet frame over the center posts and onto
the frame support. Loosen the lever lock bolt on one
support post. Slide the post outward until the center
support of the racquet support slide is positioned near
theinsidesurfaceoftheracquetframe. Securelytighten
the lever lock bolt.
Adjust the opposite post using the same procedure.
Caution: To avoid racquet damage, the center posts
should not contact the racquet prior to fixing the support
posts.
Adjusting the Frame Shoulder Supports
Being sure the shoulder supports are free to swivel in
thier mountings, simultaneously rotate the shoulder
support adjustment knobs clockwise until both shoulder
supports gently and squarely contact the frame.
TightentheFrameSupportSlidesatthe headandthroat
of the racquet until they gently contact the frame be-
tween the two center main string grommets.
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-tightenalloftheframesupportsinthesameorderas
before.
Do not overtighten any of the supports 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
moveit. Shouldanysupports losecontactwith theframe
while stringing, they should be re-tightened.

STRINGING THE FRAME
The drop weight is of a two piece design. When
assembled, it will accomodate tensions from 20 lbs. 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:Tensionsabove77lbs.requireremovalofthedrop
weight bar endcap.
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 appro-
priate end of the frame and continue through the oppo-
site center holes. Thread one end of the string through
the adjacent grommet hole and pull excess by hand.
Using a floating clamp, secure the center and the
adjacent string to each other on the inside of the frame.

6
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:Note:
Note:Note:
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
dropsbelow horizontal, repeat the aboveactionuntil the
bar comes to rest parallel to the racquet.
Whenthe correcttensionis attained,thedropweightbar
will rest horizontally as shown. For accurate tensioning,
itmustbeloweredandcome to rest at horizontal without
assistance. Manually forcing the tension bar to the
horizontal position will greatly increase the string ten-
sion and may result in racquet damage.
Ifthetensionbarcomestorestabovehorizontal,release
the string by lifting the bar and re-pull the string.

STRINGING THE FRAME
Clamping the String
Clamp the tensioned string to the next adjacent string
using the second string 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.
Starting the Cross Strings
Follow the manufacturer's recommended stringing pat-
ternforoneortwopiecestringing.Thiswilldeterminethe
starting point for the cross strings. If applicable, tie the
first cross string using an appropriate starting knot.
Weavethecrossstringsoverandunderthemainstrings
beingcareful toalternatethe weaveofeach consecutive
cross string so as to be opposite of the previously
installed cross string.
Once the final cross string is tensioned and clamped, tie
off at the appropriate hole specified by the racquet
manufacturer.

PATHFINDER AWL
The Gamma 602 includes the new Pathfinder stringing
awl which creates a pathway between or around strings
to make inserting a string through tight gromets easier
and quicker.
Insert the awl through the grommet hole in the same
manneras for traditional awls. The Pathfinder awlmust
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, leaving
the outer sheath in the grommet hole.
Insert the end of the string into the center of the sheath.
While holding pressure on the string, slowly pull the
sheath out of the grommet hole to leave the end of the
string exposed.

Adjusting the Clamps
The clamps provided with your stringing machine will
need minor adjustments according to what string type,
construction, and gauge you are using.
To 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, tightentheclampbyturningtheadjustmentknob
opposite of the handle, in the clockwise direction. If the
clampleavesimpressionsordamagesthestring,itistoo
tight and must be adjusted by turning the adjustment
knob counterclockwise.
Theclampjawsmustbecleanandfree 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 accomodate 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.

MAINTENANCE
Your GAMMA Progression 602 stringing machine is adjusted for optimum performance at the factory and needs no
further adjustments before use. After extensive use however, the machine may need minor adjusments as follows
:
Adjusting the Turntable Bushings
There are two adjustment points on the machine base.
Oneislocatedbeneaththepolystyrenebasecoverwhile
the other is accessed from below the machine.
Using the supplied 3mm hex wrench, tighten both set
screws slightly until the turntable rotates smoothly with-
out excessive free play.
Repeat procedure until final adjustment is reached.
