Important note. Please do not dismantle the pivot post assembly.
If reassembled incorrectly it will not work properly.

When fitting the tremolo arm ensure that the flat area on the post aligns with the retaining screw in the bridge bar and insert the arm.

Tighten the arm retaining screw firmly.

To adjust the height of the arm slacken the locking nut with the supplied spanner, move the arm to the desired height and tighten firmly.
(Please note the spanner supplied is different to the one in the photo.)

The pivot post assembly is preset so that the arm will not swing down when released.
If over time the resistance to rotation needs to be increased just turn the domed cap clockwise.
Sufficient tension can be achieved by hand, never use grips as this will cause damage.
