To tilt the headstock to the left or right:

1.DISCONNECT MILL/DRILL FROM POWER.

During the following steps, be aware that the headstock is top-heavy and will swing if it is not well supported once the center bolt and lock nut are loosened. Always support the headstock with one hand when loosening these fasteners. Failure to do so may result in unexpected movement of the headstock, causing damage to the machine and per- sonal injury.

2.Support the headstock with one hand, then using the included 17/19mm combo wrench, loosen the headstock center bolt and angle lock nut (Figure 30).
