Tuning Machine Tension Adjustment; Height Adjustable Locking Nut (If Applicable) - Yamaha ZV54660 Owner's Manual

TUNING MACHINE TENSION ADJUSTMENT

The tuning machines have spring-loaded mechanisms which
automatically take up wear, preventing backlash. However, it is
possible to adjust the amount of pressure required to turn the
machines. Each machine has a tension adjustment screw, as il-
lustrated.

Clockwise screw rotation tightens the machine. The tuning ma-
chines should be adjusted to the extent that they are firm, but
can turn smoothly. This adjustment is normally unnecessary, and
excessive tightening can lead to premature tuning machine wear.
