thumb pressure at its center.
2. Tighten belt tension lock handles.
NOTE: Over tensioning belt may cause

belt are aligned with grooves in the pul-
ley.
Installing Feed Handles

loose parts.

Installing the Drill Chuck
1. Clean the tapered surfaces on the
chuck and spindle with a clean cloth.
Make sure there are no foreign parti-
cles sticking to these surfaces. The
slightest piece of dirt on these surfaces
will prevent the arbor from seating
properly. This will cause the drill to
“wobble”.
2. Slide chuck into spindle of drill press.
3. Push up on chuck assembly as you
rotate it.
