G. Drill/Mill Fine Feed Handwheel - The handwheel controls the fine feed movement
of the quill in and out of the millhead.
H. Height Adjustment Drive - The height adjustment drive works with the millhead
crank to raise and lower the millhead. Insert the millhead crank over the stud, as in
Figure 4.4, rotate clockwise to raise the millhead and counter clockwise to lower the
millhead.
One revolution of the crank handle will move the millhead 0.25 inches.
I. Millhead Locking Studs - The locking studs secure the millhead in position. Insert
the millhead crank over the upper stud, rotate counterclockwise to unlock the stud.
Repeat the process on the lower stud. Position the millhead in the desired position and
lock BOTH locking studs before starting your machine.
J. Bellows - Bellows keep debris off of the Z-Axis column and rack.
