Setting up the

SMARTractor

Step 1

The SMARTractor is already pre-assembled

with the "2-lines" Spindle Adatper (for 7.15 mm

diameter) sitting in the center of the

SMARTractor.

Remove the black Spindle Adaptor from the

20mm hole in the base of the SMARTractor by

simply pressing it out onto your hand. Place it

onto your turntable's spindle to determine if it has

a snug fit w/o any play.

If not, please select the Spindle Adapter that best

fits on your turntable's spindle WITHOUT play.

Important: the selection of the 3 different Spindle

Adapters ensures that SMARTractor is accurately

mounted onto your turntable without any play at

the spindle. This is an essential starting point for

getting really precise results.

Step 2

Now insert the selected tt-Spindle Adapter in the

center 20mm hole of the SMARTractor. It will

need a small amount of force to insert it, but this

tolerance provides a firm and tight. This is wanted

to ensure absolute precision. The Spindle Adapter

centers the SMARTractor assembly of the sliding

center block and the clear acrylic positioning arm

to be used with the glass magnifier.

Step 3

Remove the thumbscrew on the back of the

central POM block and rotate the complete central

assembly to the desired tangential curve.

If you want to measure the arm mounting distance

or P2S, rotate the central block to the "UNI-P2S"

position; loosen the locking screw fixing the

positioning arm in the black POM block.

Now carefully pull the positioning arm towards

the pivot of the tonearm and place Locator Pin or

reticule right on the pivot of your tonearm. Many

tonearms have a small indentation indicating

where the exact pivot point is located.

This is ideal for precise positioning of the Locator

Pin on the pivot point.

You can now read out the exact value on the

Vernier scale.

If unsure, please see page 6 for a short tutorial

how to read the Vernier scale correctly.
