STRINGING THE FRAME
String Clamp Operation
The string clamps are a dual action design
where the string clamp and clamp base oper-
ate independently of one another.
To clamp a string, lift the string clamp, place
the string between the jaws and depress the
string clamp lever to secure the string. The
clamping pressure applied to the string should
be adjusted to provide suffi cient pressure
to secure the string when subjected to the
desired pulling tension. The diamond coated
gripper plates provide for increased friction
between the clamps and the string to allow
for reduced clamping pressure while securing and holding the string under tension.
Note that excessive pressure can damage both the strings and String Clamp.
Clamp Base Operation
To lock the string clamp base to the turntable,
rotate the clamp base locking lever clockwise.
To release the string clamp base from the
turntable, rotate the clamp base locking lever
counter-clockwise.
The locking lever should be tightened enough
to prevent clamp base slippage on the turn-
table when the desired tension is placed on
the string.
Setting Tension
The tensioner utilizes a rotary adjusting knob
along with a linear tension scale to indicate
the tension setting. The scale is divided into
3 lb. increments and each 1/3 turn of the ten-
sion knob changes tension by 1 lb. To set the
desired tension, rotate the tension knob and
align the mark on the spring guide with the
desired tension setting on the scale. When
the “0” mark on the knob aligns with the line
on the knob support the tension will be that
indicated on the scale. To increase tension
by 1 or 2 lbs turn the knob counterclockwise
until the “1” or “2” mark on the knob aligns with the line on the knob support. To decrease
tension by 1 or 2 lbs, turn the knob clockwise until the “2” or “1” mark on the knob aligns with
the line on the knob support.
