Test Run & Break-In

NOTICE

Failure to follow start up and spindle break- in procedures will cause rapid deterioration of spindle and other related parts, and never shift gears while lathe or mill is running.

It is essential to closely follow the proper break-in procedures to ensure trouble free performance. Complete this process once you have familiarized yourself with all instructions in this manual.

To begin the start up procedure:

1.Make sure the mill has been properly lubri- cated.

2.Make sure there are no obstructions around or underneath the spindle.

3.Set the spindle speed to 240 RPM.

4. Turn the mill ON (Figure 39).
