MAINTENANCE & ADJUSTMENTS

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.

Adjusting the String Clamp Jaw

Spacing

The string clamps will need minor adjust-

ments according to what string type, con-

between the clamp jaws, insert the string

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. 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 cleaning

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.
