clockwise 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.

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.

quires the travel permitted by the clamp base. If the travel is not sufficient to allow smooth

operation of, adjust the Clamp Base as outlined on page 14.

STRINGING THE FRAME

Setting Tension

The spring tensioner utilizes a rotary adjust-

ing 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 counter-

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 de-

press the clamp head 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

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 turn-

table, when the desired tension is placed on

the string. To go from the loose position to the

clamped position and back, generally re-
