Quill Lock; Depth Stop - Grizzly WOOD MILL G9959 Instruction Manual

To operate the fine down feed handwheel:
1. Tighten the knurled locking knob located on
the left side of the headstock and just
behind the fine down feed handwheel.
2. Rotate the handwheel to adjust the spindle
height.
Please note that tightening the knurled locking
knob prevents use of the adjusting handle. When
the knurled locking knob is loose, the fine down
feed handwheel no longer functions.

Quill Lock

The quill can be locked in place by tightening the
handle shown in Figure 8. This will help maintain
the depth setting while performing a milling oper-
ation. It also stabilizes the spindle and should be
used even when the quill is positioned at the
highest point.

Depth Stop

To calibrate the depth stop:
1. Roll the quill down using the lever handle
until you reach the desired depth shown on
the scale. Lock the quill with the lever lock
handle. Turn the depth stop nut until it
meets the bottom of the depth stop block.
Tighten the jam nut against the bottom of
the stop nut.
2. Roll the spindle up into the head. Place a
piece of paper on the workpiece. Loosen
the knee lock handle and raise the knee
until the drill bit or cutter just touches the
paper. Tighten the knee lock.
3. Begin drilling or milling. Note for precision
depth: set the depth stop shallow of the
desired depth by
measure. Finish to depth using the fine
downfeed handwheel with its graduated
dial and use the procedure laid out in the
previous section titled: "Graduated Dials".
