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
