Pulling Tension
To pull tension, wrap the free string clockwise around the gripper
drum and position the string between the gripper jaws.
The string must pass over the top half of the gripper before being
placed between the gripper jaws, as the tension on the string
provides the clamping force to the gripper jaws.
Gently pull the string until all slack is removed.
STRINGING THE FRAME
Clamping the First Main String
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.
Push the Tension Switch toward the right side of the machine.
The string gripper will rotate and slowly apply tension to the
string. When the set tension has been attained, the gripper will
stop rotating. As the tensioned string stretches, the gripper may
rotate intermittently, maintaining the set tension.
To release the string after clamping, push the tension switch
toward the left side of the machine. If the string gripper does not
release the string, depress and hold the Gripper Reversing
Switch once to release the string.
WARNING:
KEEP FINGERS AWAY FROM GRIPPER DRUM WHILE TENSIONING
STRING. PUSH GRIPPER REVERSING SWITCH IN CASE OF EMERGENCY.
