MAINTENANCE and ADJUSTMENTS
adjusted by turning the hex screw counterclockwise. The clamp jaws must be clean and free
from dirt, oil, and any string coating for them to grip properly.
Note: The string clamps supplied with your Gamma stringing machine can accomodate tight
string patterns such as badminton. Depending on the string pattern, the clamp may spread the
strings slightly which will not compromise the quality of the string job.

from the L.E.D. display cover plate cover. Rotate screw ("L") in small increments until the
displayed tension matches the tension indicated on the calibrator. Set the machine tension
to 75 lbs. and apply tension to the calibrator. If the measured tension is innacurate, rotate
screw ("H") in small increments until the displayed tension matches the tension indicated on
the calibrator. Replace the 2 caps in the L.E.D. display cover plate.

Adjusting the String Clamps
The clamps provided with your stringing ma-
chine will need minor adjustments according
to what string type, construction, and gauge
you are using.
To adjust, route the string through the racquet
as if you were beginning the main strings.
Clamp the strings and pull tension. If the
string slips through the jaws of the clamp,
tighten the clamp by turning the hex screw
opposite of the handle, in the clockwise di-
rection. If the clamp leaves impressions or
damages the string, it is too tight and must be
Turntable Bushing Adjustment
The GAMMA 600ES is adjusted at the fac-
tory for optimum performance. After time
and use, the turntable bushings may need
minor adjustment. An adjustment is indi-
cated when noticeable turntable looseness
or wobble occurs while stringing.
To adjust the fit between the turntable pin
and the bushings, tighten the set screw at
the top of the bushing using a 3mm hex
wrench. Tighten until the turntable rotates
smoothly without excessive free play.
Tension Calibration Procedure
If you suspect that your 600ES is not pulling
the correct tension, you should check the
tension with a Gamma Tension Calibrator
which provides a measurement of the actual
pulling tension being applied by the ma-
chine.
With the 600ES machine tension set at 20
lbs., place one end of a calibrator equipped
with synthetic string into a string clamp.
Place the opposite end into the string grip-
per and apply tension. If the measured ten-
sion is inaccurate, remove the 2 small caps
