NOTE: The belt tension is pre-set at the factory and should only require adjusting if the belt stretches over time or is replaced.

1.Open pulley cover (X) Fig. 14 and side door (AA) Fig. 16.

2.Pull down belt tensioning lever (Y) Fig. 15 to release belt tension. Do not lock it below the tab (Z).

3.Turn thumbwheel (DD) Fig. 19 clockwise to increase tension, or counterclockwise to decrease tension.

NOTE: A properly tensioned belt should deflect approximately 1/4" (6.4 mm) with moderate finger pressure.

4.Lift lever (Y) Fig. 15 and snap into place.

5.Close lower side door (AA) Fig. 16 and pulley cover

(X) Fig. 14 securely.

ELECTRONIC VARIABLE SPEED CONTROL (46-460 ONLY)

Once you select a speed range (as described above in Changing Pulleys section), use the speed control knob (EE) Fig. 20 to vary the speed within that range. As you face the lathe, turn knob forwards (towards you) to increase speed, turn it backwards (or away from you) to decrease speed.

To reduce the risk of injury, always set the speed control knob to its lowest setting before starting the lathe. Never start a workpiece at maximum speed.

INDEXING PIN

The lathe is equipped with an indexing pin (FF) Fig. 21. The pin allows the spindle (GG) to be locked in 24 positions—as labeled on indexing wheel (HH)—for use in various operations. To use:

1.Rotate idexing wheel (HH) so spindle (GG) is in desired location.

2.Pull back index pin (FF) slightly from retaining groove.

3.Rotate indexing pin 90 degrees so the crosspin (II) lines up with recess, as shown in Fig. 21a.

4.Release indexing pin (FF) so that it engages numbered indexing wheel (HH) Fig. 21 and locks spindle (GG) in place.

Do not turn on lathe with index pin engaged. Doing so could damage the lathe.

Do not use the index pin (FF) to lock spindle when removing faceplate because this can damage the pin. To remove faceplate, follow directions under Removing Faceplate section.
