NOTE: For right hand operation (feed
handle on right side) turn spring counter-
clockwise to the next notch and engage
with the 4mm cap screw.
6. Finger tighten inner nut against spring
housing. Do not overtighten as this will
restrict quill movement.
7. Loosen depth scale lock and check
quill return by rotating feed handles,
lowering quill.
8. Proper tension is achieved when quill
returns gently to full up position when
released from 3/4” depth.
9. If there is not enough tension on
spring, repeat steps 5-8 moving only
one notch each time and checking
tension after each repetition.
10. After adjusting spring, replace outer
nut and tighten to inner nut. But do not
overtighten against inner nut.
11. Check quill movement to make sure it
is smooth and unrestricted. If move-
ment is too tight, loosen outer nut and
slightly loosen inner nut until unre-
stricted. Retighten outer nut.
Adjusting Belt Latch Guard
The button latch is adjusted at the factory
to be self latching when the pulley guard
lid is closed. If adjustment is needed,
loosen the two screws securing the latch
to the lid and move latch back until the lid
closes without depressing the button. The
button can also be adjusted up and down
to assure lid closes tight by loosening the
two screws in back of the latch button,
and moving the button up or down as
needed.
