The truss rod adjusting nut

Clockwise (green arrow) rotation corrects forward bow. Anti-clockwise (yellow arrow) rotation for correcting back bow. Note: 5mm Allen key required for adjustment (not supplied)

IMPORTANT Never make forced adjustments especially if the nut will not easily rotate. It is possible to over adjust the truss rod and cause irrepairable damage to your guitar. If you are uncertain about making any adjustments please ask your authorised Takamine retailer or a reputable guitar technician.

Once the neck is in the correct setting, further adjustments to lower action can only be made at the saddle and the nut. This is done by removal of material from the saddle and then nut string slots, in that order, if necessary. Care must be taken, as the action cannot be properly raised afterwards without replacing either of these integral parts. Again, an authorised retailer or guitar technician should be able to make adjustments. Takamine do not guarantee guitars against string or fret buzz because the action is set too low. If you wish to have a very low action set on your guitar this can usually be done but may be chargeable.
