MAINTENANCE
Your GAMMA 600FC stringing machine is adjusted for optimum performance at the factory and needs no further
adjustments before use. After extensive use however, the machine may need minor adjusments as follows :
Adjusting the Clamp Pressure
The clamps provided with your stringing machine will
need minor adjustments according to what string type,
construction, and gauge you are using.
To adjust the gap (clamping pressure) between the
clamp jaws, insert 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 compressing the clamp
jaws together by hand while turning the Adjustment
Knob, in the clockwise direction. If the clamp leaves
impressions or damages the string, it may be exces-
sively tight and should be adjusted by turning the hex
screw counter clockwise to open the gap between the
jaws. The clamp jaws should be cleaned periodically to
be free from dirt, oil, and any string coating for them to
grip properly.
Note: The string clamps supplied with your 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.
Adjusting the Turntable Bushings
There are two adjustment points on the machine base.
One is located beneath the polystyrene base cover while
the other is accessed from below the machine.
Using the supplied 3mm hex wrench, tighten both set
screws slightly until the turntable rotates smoothly with-
out excessive free play.
Repeat procedure until final adjustment is reached.
