 (please read and understand all instructions before proceeding)


1) If installing tuning rollers with the strings still on the instrument, detune the instrument to remove all tension from the machine head.


2) Using a small screw driver ( use proper screwdriver head + or - ) carefully remove existing button screw.

3) Gently pull button from button post while being careful NOT TO remove any existing plastic and/or metal washers.


4) Line up the flats on button post with flats inside roller. DO NOT FORCE! HOLD BUTTON POST END WHILE PUSHING ROLLER ONTO BUTTON POST. MAKE SURE PARTS ARE PROPERLY ALIGNED
BEFORE APPLYING ANY PRESSURE!!


5) While using a finger or thumb to secure the gear mechanism, return screw and tighten.

6) Roller shouldn’t feel loose. Roller should be snug and smooth in both directions.
DO NOT OVER TIGHTEN!! TUNE UP AND ENJOY!!



(Tuning rollers are designed to fit on most existing machine heads or tuning gears or straps that have
a removable button screw. Some buttons may require a longer screw (i.e. Sperzels™). Alternate
screws and/or washers that may be necessary for a correct installation not included)
