9.9 FEED DIRECTION CONTROL
The Feed Direction Control (B, Figure 12) determines
whether the power feed will move up, down, or not move
at all. The position of the knob depends upon the direction
of spindle rotation (see the Motor Switch section). The
position of the control may be changed with the system
stopped or running. If the control does not engage easily,
move the fine feed handwheel (A, Figure 12) back and
forth to aid engagement.
If the spindle is rotating clockwise, in is downfeed; out is
upfeed. If the spindle rotation is counterclockwise, out is
downfeed; in is upfeed. Neutral position is between the in
and out position.
9.10 COARSE FEED HANDLE
The Coarse Feed Handle (A, Figure 13) is located on the
right side of head. The Coarse Feed Handle is used for
non-precision drilling operations and for moving the quill
to a specific depth. A return spring will retract the spindle
automatically once the handle is released.
It is recommended that the Feed Direction Knob be
left in the neutral position when not in use.

9.11 QUILL LOCK LEVER
The Quill Lock Lever (B, Figure 13) is located on the right
side of the head. Rotate the handle clockwise to lock the
quill in a desired position. Rotate the handle counter-clock-
wise to release.
9.12 MICROMETER ADJUSTING NUT
The Micrometer Adjusting Nut (A, Figure 14) is located
on the front of the head. Use for setting specific spindle
depth.
9.13 FINE FEED HANDWHEEL
When the controls are set for the Fine feed using Hand-
wheel position (see Figure 5), the Fine Feed Handwheel
(A, Figure 12) can be used for manual fine feed control in
either upward or downward direction of the quill.
!
Remove the Manual Fine Feed Handwheel when not
in use. Failure to comply may cause serious injury.
