Assembly Instructions
Base Leg Assembly
The stringing machine uses a four leg base design. The
legs must be assembled to the support post before use.
Remove the lower column support, the upper column
support, four (4) legs, four (4) socket head cap screws
and four (4) flat head cap screws from the small shipping
carton.
Base Leg Assembly (Cont.)
Align the holes in the leg flange 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 bottom hole.
Repeat this procedure for the three remaining legs.
“A”
Base Leg Assembly (Cont.)
To complete the base stand, screw the height adjustment locking knob
(“A”) into the side of the support column. The locking knob should not
protrude beyond the inside of the support column at this time.

Assembly Instructions
Unpacking the Tensioner Assembly
The tensioner assembly is packed inside the inner
carton and is bolted to a sheet of wood with four (4) bolts
to prevent damage during shipment. Another sheet of
wood is bolted to the underside of the inner carton
through the first piece of wood. First locate the nuts
attached to the bolts that secure the outer piece of wood
to the inner piece of wood. Remove the nuts and with
assistance carefully lift the tensioner assembly from the
inner carton and lay it floor. To remove the inner piece of
wood from the base of the machine, raise each end and
remove the four (4) shipping bolts from the underside of
the wooden sheet. Note: Please retain the bolts, wood
and cartons for future shipment.
Foot Installation
CAUTION ! To maintain the alignment between the
fiberglass covers and the frame, it is very important
that the feet be installed before removing the four
center screws that attach the tensioner assembly to
the upper post flange.
To install the feet, tilt the tensioner back on its side and
screw the four feet into the holes at the corners of the
base.
Stand Upper Post Installation
After installing the four corner feet, remove the four (4)
button head cap screws from the base of the assembly.

Assembly Instructions
Stand Upper Post Installation (cont.)
With the height adjustment cap screw on the upper post
facing the right side of the tensioner, align the four (4)
holes in the upper post flange with the holes in the
tensioner base. Secure the flange to the base with the
four cap screws.
Height Adjustment
The height of the machine is adjustable from 39” to 46”.
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.
