Feed direction control
The
Feed Direction Control
(B, Figure 10) determines
whether the power feed will move up, down, or not move
at all. The position of knob depends upon direction of
spindle rotation (see the
Motor Switch
section). Position
of the control may be changed with the system stopped
or running. If the control does not engage easily, move
fine feed handwheel (A, Figure 10) back and forth to aid
engagement.
If spindle is rotating clockwise,
in
is downfeed;
out
is
upfeed. If spindle rotation is counterclockwise,
out
is
downfeed;
in
is upfeed. Neutral position is between
in
and
out
position.
It is recommended that Feed
Direction
Knob be left in neutral
position when not in use.
