are disengaged before starting the lathe/
mill! Thoroughly familiarize yourself with all
the controls and their functions before using

The purpose of the test run is to make sure the
lathe/mill and safety features operate correctly
before proceeding with additional setup.
To begin the test run & break-in procedure:
1. Make sure the lathe/mill is lubricated and the
headstock oil level is full. Refer to Page 36 if
required.

position, the range lever to the red-dot posi-
tion, and the lead screw lever to the neutral
position as shown in Figure 7.
