ASSEMBLY INSTRUCTIONS
Installing the Base Legs
A
The PRO 100 is shipped with the legs separate from the base and requires assembly
before use.
Hole (A) in the machine base is the attaching
point for the base leg.
Place one screw onto the end of the 4mm
hex wrench. Carefully insert the screw
through the large hole in the bottom of the leg
and continue through the small hole at the
top of the leg.
While holding the leg, screw and wrench as
one unit, place the exposed end of the screw
through hole (A) in the machine base.
Place one washer over the exposed screw
end inside of the machine base. Thread one
locking nut onto the screw end.

ASSEMBLY INSTRUCTIONS
Installing the Base Legs ( cont. )
Using the included 10mm box wrench, securely tighten the locking nut.
The completed leg / base assembly.
Replace the base endcap making sure the
notched side of the endcap is aligned with
the leg attachment screw.
3
ASSEMBLY INSTRUCTIONS
Installing the Turntable
Insert the turntable center post into the bushing assembly of the machine base.
Installing the Support posts
Slide each support post onto the end of the
turntable bar. The posts should be oriented
so as to angle away from the turntable center
post.
Installing the Drop Weight
Remove the endcap from the tension bar
and slide the drop weight onto the bar. The
weight should be oriented with the knob end
closest to the string winder. Replace the
endcap.

MOUNTING THE RACQUET
Installing the Racquet Support Adapters
The PRO 100 is supplied with two styles of
Racquet Support Adapters. A thick profile
adapter for widebody racquets and a thin
profile adapter for conventional racquet
frames. The Adapters are also tapered, use
the highest side of the adapter that does not
interfere with the string grommet holes.
Adjusting the Frame Support Posts
Place the racquet frame over the center
posts and onto the frame support posts.
Loosen the locking screws on one support
post and slide the post in the appropriate
direction until the plastic adapter contacts
the frame. Securely tighten the locking
screws. Adjust the opposite post in the same
manner.
It is extremely important both plastic adapters are in contact with the frame to prevent
racquet damage.
Securing the Racquet
With the frame support posts properly adjusted, place the frame hold down plates
over the center screws and tighten the clamp
bar knobs securely. Do not overtighten the
knobs as frame damage may occur.
Note: Inverted throat racquet frames may
require the throat clamp plate to be rotated
180 degrees to match the frame.
5
STRINGING THE FRAME
Starting the Main Strings
To begin stringing the main strings, count
the number of holes at the throat of the
frame, which will determine the starting point.
For racquets with 4 or 8 holes at the throat,
the main strings will begin at the head. For
racquets with 2 or 6 holes at the throat, the
main strings will begin at the throat.
Thread the two ends of the string through the
two center grommet holes at the head or
throat as determined in the previous step.
Route the strings through the opposite center
holes.
Clamping the First Main String
Thread one end of the string through the
adjacent grommet hole and pull excess by
hand. Clamp both the center and the adjacent string to each other on the inside of the
frame.
Pulling Tension
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.
6
STRINGING THE FRAME
Pulling Tension
While holding the string gripper drum with
your hand, lift the tension bar to approx. 45
degree angle and let fall. If the tension bar
drops below horizontal, repeat the above
action until the bar comes to rest parallel to
the racquet. The set tension will be reached
when the bar rests horizontal.
If the bar comes to rest above horizontal,
release the string and re-pull tension.
Manually forcing the bar into the horizontal
position will greatly increase string tension
and may result in racquet damage.
Clamping the String
Clamp the tensioned string to the next adjacent string using the secong string clamp.
Release the tensioned string 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 pattern for one or two piece stringing. This will determine the starting point for
the cross strings. Weave the first two cross
strings and pull tension as per Step 3. Clamp
the cross strings as per Step 4.
7
STRINGING THE FRAME
Finishing the String Job
Weave and tension the remaining cross
strings and tie off at the specified grommet
hole.
Remove the strung racquet from the Super
Stringer in the reverse order of mounting.
