The spring’s tail is located on the perim-
eter 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 may result in per-
sonal injury.
2. Put on gloves and pull the spring cover out
until 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 (Figure 40).
Do not completely remove the cover! If
you remove the spring cover, the spring
will uncoil rapidly and create a great risk
of injury.

4. Tighten the black thumb knob.
The spring tension for automatic quill recoil has
been pre-set at the factory. It should not need
adjustment under most normal circumstances. 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 two or three turns
(Figure 39).
