Loosen the two X-axis table lock handles on
the front side of the table.
4.
Plug the power feed unit into a grounded
110V power source.

On the X-axis power feed to the right of the
table, make sure the directional lever is in the
center position (neutral) and turn the speed
dial to "2"—the "2" will be top center.
6.
Flip the power feed power switch up (ON)
and move the directional lever to the left to
start the table movement.

Confirm the table is moving to the left and
watch for the table limit stop to hit the limit

ment.
Note: Alternatively, you can push in the limit
switch plunger with a tool—not your finger—
to make sure table movement will stop when
the limit switch is activated.
8.
Move the directional lever on the power feed
through the center position and all the way to
the right—this should start the table moving
to the right.
9.
Confirm the table stops moving when the
right table limit stop engages the limit switch,
then move the power feed directional lever to
the center position and flip the power switch
down (OFF).
