Adjusting the String Clamp Jaw 
Spacing

The string clamps will need minor adjust-
ments according to what string type, con-
struction, 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 begin-
ning the main strings. Clamp the strings 
and pull tension. If the string slips through 
the jaws of the clamp,  tighten the clamp 
by squeezing 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 excessively tight and should be adjusted by 
turning the Adjustment Knob 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 residue 
to grip properly. Knife sharpening stones are excellent for removing build-up on the diamond 
coated surfaces and are available.

MAINTENANCE  &  ADJUSTMENTS

Clamp Base Locking Nut Adjustment

In the event the Locking Lever rotation is 
insuf

fi

 cient to ensure smooth operation of the 

clamp base, very minor adjustments to the 
Clamp Base Locking Nut can be made with 
the supplied 17mm socket. Tighten or loosen 
the locking nut in very small increments to 
provide more clamping pressure or running 
clearance as needed.

Quick Action Clamp Base Removal

Quick Action clamp bases can be removed 
from the turntable for maintenance or clean-
ing by removing clamp stop located at the 
end of the slot in the turntable. To remove the 
clamp stop, remove the two screws holding 
the clamp stop in place from the underside of 
the turntable.  Lift the clamp stop out of the 
slot, slide the clamp base to the end of the 
slot and lift it out. Replace the clamp base and 
clamp stop in reverse order.
