Floor Stand Base Assembly
The stringing machine uses a pedestal oor stand design that can be set up to orient the
machine perpendicular to the operator or to position the machine on an angle.
The base plate must be assembled to the lower column before use. Remove all parts from
the shipping carton to conrm that contents match the list of parts on Page 4.
Perpendicular Base Assembly
To assemble the Floor Stand Base to be PERPENDICULAR to the operator secure the base
placing the four 8mm bolts in the holes without the arrow.
ASSEMBLY INSTRUCTIONS
Angled Base Assembly
To assemble the Floor Stand Base to have ANGLED operator position secure the base placing the four 8mm bolts into the holes marked with an ARROW.

Floor Stand Upper Column Installation
With the height adjustment cap screw on the
upper column facing the brake lever & string
length meter, align the holes marked “X” in the
upper column ange with the threaded holes
in the slide brackets of the machine base.
Floor Stand 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.

ASSEMBLY INSTRUCTIONS
Floor Stand Upper Column Installation (cont.)
Secure the ange to the slide brackets in
the base of the machine with the six M6 cap
screws packed with the oor stand.
Caution: When securing the screws to
the slide brackets cross threading or over
tightening may damage the threads in the
slide bracket or cause the threads to strip out.
7
The string reel holder pin is an 8 mm rod
with threads on both ends and at surfaces
machined on one end. Thread the end of the
pin without the at surfaces into the threaded
boss on the right side of the lower column.
Using the M6 open end wrench positioned
on the at surfaces, securely tighten the pin
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 rst reel on the rod,
slide two M8 washers over the pin and slide
them to the boss on the lower column. After
the 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 pin and attach the
threaded knob to the end of the rod.

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 and while in storage. 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.
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.
