Your mill is also equipped with a power feed unit
for X-axis table movement. Refer to Figure 20
as you familiarize yourself with the components
of these systems and their descriptions listed
below.

Figure 20. X-axis power feed system.
A. Limit Switch. Powered table movement will
stop when either of the side plungers are
depressed by the limit stops.
B. Limit Stop. Position the limit stops along the
table (one on either end of the table) to acti-
vate the limit switch at the desired position.
C. Rapid Traverse Button. Once the directional
lever has been activated, pushing this button
will cause the power feed to move the table
at full speed.
D. Directional Lever. Moving this lever to one
side or the other will move the table in that
direction. The center position is neutral.
E. Speed Dial. Controls the speed that the table
moves—turning the dial clockwise causes
the table to move faster.
F. ON/OFF Switch. The master power switch
for the power feed.
G. Ball Handle. Use this handle to manually
position the table.
H. Travel Graduated Dial. Marked in 0.001"
increments, each complete revolution is equal
to 0.200" of table travel.

Stay clear of manual ball handles when
using power feeds to avoid entanglement
and personal injury.
To operate the X-axis power feed:
1.
Loosen the X-axis locking handles (see
Figure 21).

Figure 21. X-axis locking handles, limit stops,
and limit switch.
2. Using a 12mm wrench, position the limit
stops along the table to confine the distance
you want the table to travel.
Before running your power feed, be sure
there is enough running clearance between
the table, spindle, vise/clamps or jigs. Be
aware that all of these objects represent
potential pinch points.
3. Move the directional lever to the center or
neutral position.
4. Connect the power feed to a grounded 110V
power source.
5.
Flip the ON/OFF switch up to turn the power
feed ON.
