Upper Belt Guard,
loosen the cover securing the stud and pivot the belt tensioner to relax
tension on the belt.

and turn the lever down. The lever can be clearly seen on the bottom right hand corner of

FINE FEED DOWN FEED
The up and down motion of the drill press spindle is controlled just like any other drill press with a
Quill
Lever.
But unlike most drill presses, the Model B is supplied with a
Fine Down Feed Knob,
indicated by
the arrow in
Figure 29.
Figure 29.
Move the handle while depressing knob.
To activate this feature, rotate the
Quill Lever
while depressing the black knob in the middle of the centre
of the hub as in
Figure 29.
The knob will engage and the spindle will no longer move using the
Quill
Lever.
Rotating the
Fine Down Feed
knob in a clockwise direction will cause the spindle to go down. To
disengage this feature, rotate the
Fine Down Feed
knob and pull on the knob in the centre of the hub.
Rotating the handwheel will always aid in engaging and disengaging this feature.
