Return Spring Tension; Table Leadscrews - Grizzly G1006 Instruction Manual

Return Spring Tension

The spring's tail is located on the perimeter
of the spring housing. This part may be
sharp! Use leather gloves or a heavy shop
towel to cover the tail while loading or
unloading return spring pressure. Failure
to use such precautions will results in per-
sonal injury.
The spring tension for automatic quill recoil
has been pre-set at the factory. It should not
need adjustment under most normal circum-
stances. If it does need adjustment, the spring
housing is located on the left side of the head.
To adjust the spring tension:
1. Loosen black thumb knob, located in the
center of the spring housing, by only two or
three turns.
Do not completely remove the cover! If you
remove the spring cover, the spring will
uncoil rapidly, probably cause injury, and
be nearly impossible to put back together.
2. Pull the spring cover out a little bit so the
notches just clear the roll pin. Hold the
spring cover tightly or the force of the
spring will make it spin out of control.
3. Rotate the cover to adjust the tension.
Push the cover back in to engage the roll
pin in one of the notches.
4. Tighten the black thumb knob.

Table Leadscrews

When you turn the handwheels to adjust the posi-
tion of the table, you will notice slight play in the
handwheel before the table begins to move. If
this play exceeds 0.010" (measured with the dial
at the base of each handwheel), then you will
need to adjust the leadscrews.
To adjust the Y-plane leadscrew:
1. Access the underside of the base through
the hole in the bench under the base.
2. Locate the adjuster midway along the lead-
screw, inside the base.
3. Tighten the Allen
adjuster.
4. Test the adjustment by turning the front
handwheel. You should detect less than
0.010" of play.
To adjust the X-plane leadscrew:
1. Locate the longitudinal leadscrew adjuster
under the middle of the table. The Allen
head on the adjustment screw faces to the
right.
2. Tighten the adjustment screw with a long
Allen ® wrench.
3. Test the adjustment by turning one of the
side handwheels. You should detect less
than 0.010" of play.
These adjusters may require you to fabricate
extensions for your hex wrenches. Make adjust-
ments in small increments. Over-tightening can
add unnecessary wear to both the leadscrews
and the adjusters.
