machines, please refer to a professional luthier for installation.

INSTALLATION

2. Insert the tuning machine though the hole in the headstock
and align to the desired position.
3. Mark position of mounting screw and drill 1.5mm pilot hole
with a 6mm-8mm depth if it does not align with existing hole.
4. Once tuning machine is in position, gently push with thumb on
the back of machine to make sure it is flush against headstock.
5. Apply washer and nut to tuning machine post and tighten by hand.
6. Further tighten nut using wrench or nut driver until secure.
DO NOT OVER TIGHTEN.
7. Place mounting screw through the tuners eyelet and tighten.
