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 illustrated. Loosen HEIGHT ADJUSTABLE LOCKING NUT 1) Remove 3 pcs. of hexagonal screws fixing the Lock Pads. (illustration - A) 2) Loosen 4 pcs. of screws fixing the Nut Base. (illustration - B) 3) Adjust the height by the Height Adjustment Screw. The Nut Base gets higher by clockwise rotation, and lower by counterclockwise rotation. (illustration - C) A C Tighten Clockwise screw rotation tightens the machine. The tuning machines 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. 3 B NOTE: As the height has been adjusted in the best condition in the factory, please avoid the adjustment unless you have suitable experience. We suggest that you entrust this adjustment to your dealer. @F@H@PN@FOJOEE
