Depth Stop

The depth stop limits the downward movement of the cutting tool. With the use of the depth pointer adjustment knob (see D in Figure 12), it can be adjusted anywhere within 0"–5". This is useful when performing repeat operations.

Headstock

Movement

The headstock travels up and down the column, and tilts 90° left and right relative to the table.

Raising/Lowering Headstock

Loosen the lock handles shown in Figure 13, then use the Elevation (Z-Axis) Switch (see Figure 14) on the control panel to raise/lower the headstock.

The Z-axis crank will rotate rapidly and may cause impact injuries if left attached during powered Z-axis operation. Always remove Z-axis crank before using the switch on the control panel.

The limit stops shown in Figure 15 stop head- stock travel when contacted by the limit block.
