MAINTENANCE and ADJUSTMENTS

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 Clamp Jaws

The

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.

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 increments to provide more

clamping pressure or running clearance as needed.

Turntable Bushing Adjustment

The Progression STII is adjusted at the factory for

optimum performance. After time and use, the turn-

table bushings may need minor adjustment. An adjust-

ment is indicated when noticeable turntable looseness

or wobble occurs while stringing.

To adjust the fit between the turntable pin and the

bushings, tighten the set screws located on the back

side of the tensioner bar post using a 3mm hex wrench.

Tighten until the turntable rotates smoothly without

excessive free play.
