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 beginning
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 turn-
ing 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.
NOTE: Due to the bearings used in the Clamp Lever the action of the Clamp Lever is
very light making it easy to apply excessive clamping pressure. Clamps that are set
too tight can damage the string as well as the string clamp 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
insuffi 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 and
a hex wrench as a lever. 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.
