MAINTENANCE & ADJUSTMENTS
Switching the Buzzer Off and On
The stringing machine is equipped with a buzzer that sounds when any key or button is
pressed, when the tensioner has pulled a string to the end of its travel and is not yet at tension,
or when there is a problem with the some fucntion of the machine. The buzzer can, however,
be disabled if desired for normal keypad entries.
To disable the buzzer, turn the machine on and while the display is counting down from 9 to
0, press and hold the Enter/Clear button for at least 5 seconds. The buzzer will be disabled
and will remain disabled. It can be enabled again by following the same steps listed above.
NOTE: Even when disabled, the buzzer will sound if the tensioner has pulled a string and
reached the end of the track prior to reaching the desired tension in the string, or if there is
some other problem with the machine that requires attention.This is meant to alert the user
of a problem, and can not be disabled.
Adjusting the Clamp Base
In the event the Locking Lever rotation is
insufficient to ensure smooth operation of
the clamp base, very minor adjustments to
the Clamp Base Locking Nut can be made
with a 17mm socket. Tighten or loosen the
locking nut in very small increments to pro-
vide more clamping pressure or running
clearance as needed.
Tension Calibration Procedure
Each stringing machine has been checked
and calibrated at the factory using accu-
rate load sensing devices to ensure that
the machine pulls at the correct tension.
However, if you suspect that your machine
may not be pulling at the correct tension you
can check the pulling tension with a calibra-
tor and make adjustments if needed.
Most tension calibrators (such as a Gamma Tension Calibrator) function by clamping off the
string attached to one the end of the calibrator and applying tension to the string located
on the opposite end of the calibrator. The tension measured by the calibrator will then display
the tension being applied to the calibrator by the machine. If the calibrator and tensioner
do not match then you can adjust the tensioner as follows:
(1) Turn the machine off and restart the machine while holding down the Test buttonuntil
count down is complete. 22 lbs should appear on the display. (2) Apply tension to the
calibrator. (3) If the tension reading on the calibrator does not match the tension displayed
on the machine, use the tension indexing buttons to match the display to the calibrator reading
and press the Enter/Clear button (4) Release the tension applied to the calibrator and 44 lbs
should appear on the display. (5) Repeat steps #2-#4 for 44, 66 & 88lbs. (6) After completing
the adjustment at 88lbs the display will show 00 lbs. (7) Restart the machine without holding
any buttons and the calibration adjustment will be complete.
