String Gripper Operation
To insert a string into the linear string gripper, wrap the
free end of the string clockwise around the roller guide
and insert the string between the diamond dust coated
string gripper plates. Excessive slack in the string
should be removed before applying tension. Pull the
string perpendicular to the gripper plates and begin
tensioning. As tension is applied, the grippers will
engage to hold the string. For adjustment of the parallel
plates, see "Setting the Gripper Plate Spacing" on page
18.

MITTED TO OPERATE THIS MACHINE WITHOUT
ADULT SUPERVISION.
Tensioning a String
After the string in inserted into the parallel plate
grippers, press the tensioning button switch on the
front panel of the machine, or press the foot pedal
switch to activate the tensioner. The using the fast
pulling speed (see section on Control Panel Functions
and features) the tensioner will start pulling at full
speed and then slow down as the tension in the string
approaches the tension setting. When the tension in
the string reaches the tension setting, the LED display
will begin to flash, and the string will be ready to clamp
off. In the event that the tensioner reaches the end of
its travel and the string is not yet at tension, the buzzer
will sound. Clamp off the string and repeat the tensioning
process. If one of the keys on the control panel are
accidently pressed while tensioning a string, the
tensioner will automatically reverse and release the
string being tensioned.
