MAINTENANCE and ADJUSTMENTS
Clamp Base Locking Nut Adjustment
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 the supplied 17mm wrench. Tighten or
loosen the locking nut in very small incre-
ments to provide more clamping pressure or
running clearance as needed.
Turntable Bushing Adjustment
The Progression ESII+ is adjusted at the
factory 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.
Adjusting the Clamp Jaws
The
“
Quick Action
”
Clamps will need
minor adjustments according to what string
type, construction, and gauge you are using.
To adjust the gap (clamping pressure) be-
tween 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 compress-
ing the clamp jaws together by hand while
turning the Adjustment Knob, in the clock-
wise direction. If the clamp leaves impres-
sions or damages the string, it may be excessively 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.
