STRINGING THE FRAME

Setting Tension

The GAMMA 6004 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 tension 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.

Clamp Head Operation

Cam-Lock Clamps are of a dual action design where

as the clamp head and clamp base operate

independently of one another.

To clamp a string, lift the clamp head and place the

string between the jaws and depress the clamp head

lever to secure the string. The clamping pressure ap-

plied 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.

Clamp Base Operation

Rotate the Base Locking Lever clockwise to secure the

clamp base to the turntable.

Reverse the clamping procedure to unlock the string

clamp. The Locking Lever is spring loaded to assist the

unlocking of the clamp base.

The Locking Lever should be tightened enough to

prevent clamp base slippage on the turntable, when the

desired tension is placed on the string. To go from the

loose position to the clamped position and back, gener-

ally requires the travel permitted by the clamp base. If

the travel is not sufficient to allow smooth operation of,

adjust the Clamp Base Locking Nut as outlined on page

16.

Note: If the string slips in the string clamp while

tensioning, adjust the gap between the clamp jaws as
