Setting the String Tension
String tensions may be entered and stored into
one of nine memory storage settings (See sec-
tion on Control panel Functions and features) by
using the keypad or the tension index buttons.
While a tension setting is entered, the value
displayed will be temporary until the “Enter”
button is pressed to store it in one of the nine
permanent memory settings.
Aramid fi ber and metallic strings will generally string up tighter on the machine compared
to synthetic or natural gut strings. Therefore, when stringing with Aramid (Kevlar, Technora)
hybrid strings or metallic strings, we recommend setting tension 4-5 lbs. lower than you would
normally use for synthetic or natural gut strings.
STRINGING THE FRAME
Applying Tension
To apply tension, wrap the string clockwise
around the gripper drum and position the
string between the gripper jaws.
The string must pass over the upper gripper
jaw before being placed between the gripper
jaws, as the tension on the string provides the
clamping force to the gripper jaws.
Before applying tension, gently pull the string
until all slack is removed.
Getting Started
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.
Handy tip: The tear drop shaped holes
towards the back of the shoulder supports
are handy for holding the loose end of the string while tensioning the string. Simply insert the
loose end into the tear drop shaped holes and slide the string toward the point of the hole.
CAUTION: NEVER TENSION A STRING WITH YOUR FINGERS BETWEEN
THE STRING AND THE UPPER GRIPPER JAW AS SERIOUS INJURY COULD
RESULT IF YOUR FINGER IS CAUGHT BETWEEN THE STRING AND THE
UPPER JAW DURING TENSIONING.
