Rotate the center speed dial to "0", and use
the direction lever to select the table move-
ment direction.

Adjust the speed dial to move the table at the
required feed rate for your operation.
Note: Power feed rates are difficult to pre-
cisely adjust. We recommend that you exper-
iment with different dial settings to find the
feed rates that best work for your operation.

When you are finished using the power feed,
leave the directional lever in the center or
neutral position, and flip the ON/OFF switch
down to turn the power feed OFF.

3.
With one hand pressing against the head-
stock, apply pressure in the direction of the
desired tilt, then use a 19mm wrench to turn
the tilt bolt (see Figure 24).
Note: Turn the tilt bolt clockwise to tilt the
headstock forward and counterclockwise to
tilt the headstock back.
4.
Re-tighten the tilt locking bolts to secure the
headstock in place.
Always lock the headstock firmly in place
after adjusting the tilt or rotation. If the
headstock slips during milling operation, the
spinning cutter could bind and break apart,
causing serious personal injury or property
damage.
