5-1. Feed Shaft Spring Tension:
The feed shaft return spring is adjusted at the factory;
however, during the life of the drill press you may want to
adjust the feed shaft return spring so the feed shaft
return pressure suits your operating needs.
To adjust the feed shaft spring tension:
1. UNPLUG THE DRIL PRESS!
2. Wipe off any oil on the spring lock cover so it does
not slip in your fingers when you hold the cover from
spinning (see Figure 16).
3. While holding the spring lock cover against the side
of the head stock so the cover stays splined with the
locking lug; loosen the jam nut and loosen the cover
nut approximately 1.4" (see Figure 18).
4. Put on heavy leather gloves to protect your hands
from possible lacerations if the spring uncoils during
the next step.
5. Pull the cover outward just enough to disengage the
spring-cover lock slot from the locking lug. Note: It is
important to keep a good grip during this step. Letting
go of the cover will cause the spring to rapidly uncoil.
6. Rotate the cover counterclockwise to increase spring
tension, or let the cover slowly unwind in the
clockwise direction to reduce spring tension.
7. Engage the next available spring-cover lock slot with
the locking lug and hold the spring lock cover tightly
against the side of the headstock.
8. Snug the cover nut against the spring cover just until
