The feed shaft return spring is adjusted at the fac-
tory; however, during the life of the drill press you
may want to adjust the feed shaft return spring at
a stronger return pressure.
To adjust the feed shaft spring tension, do
these steps:
1. UNPLUG THE DRILL PRESS!
2. Wipe off any oil on the spring lock cover so
it will not slip in your fingers when you hold
the cover from spinning. See Figure 18.
3. Make sure the quill shaft is completely seat-
ed and the depth stop reads “0”. See Figure
19.
4. Put on thick leather gloves and hold the
spring cover against the side of the head-
stock so the cover stays splined with the
locking lug; remove the jam nut and loosen
the cover nut approximately
1
⁄4" (6.4mm).
See Figure 19.
5. Pull the cover outward just enough to dis-
engage the spring-cover lock slot from the
locking lug. See Figure 20.
6. Rotate the cover counter clockwise to
increase spring tension, or let the cover
slowly unwind in the clockwise direction to
reduce spring tension. See Figure 20.
MAKE SURE your machine is
unplugged during all
assembly, adjustments, or
maintenance procedures.
Otherwise serious personal
injury may occur!
WEAR safety glasses
when adjusting springs.
Serious injury may occur
if this warning is ignored!
