HV-3 BENCH-TYPE UNDERCUTTER
INSTRUCTIONS
INITIAL ASSEMBLY:
Turn the vertical adjustment hand wheel (30-30) over and tighten the set screw. Remove the
carriage stop screw with modified Black Tee Know from the end of the roller slide and install
the carriage assembly (30-2 etc) by inserting the carriage roller bearings into the notches of
the slides. Replace the stop screw with Knob. Three countersunk holes are provided for
screwing the base to a bench.
FOR SLOTTING HORIZONTAL COMMUTATORS:
Fasten the end of the operating handle (30-18) to the base of the carriage (30-2). Position
handle between dowel pins and thread bolt through spacer (30-21) into carriage base (30-
2).
FOR SLOTTING VERTICAL COMMUTATORS:
Fasten the end of the operating handle (30-18) to the bottom of the carriage lifting arm (30-
15).
CHANGING SAW SPINDLES:
To remove the spindle, first, remove the pulley guard (30-28). Loosen the two hollow head
set screws in the motor support bracket (30-3) that hold the spindle in position. Loosen the
tension on the drive belt and slip off the belt. Slide out the spindle housing along with the
pulley. When inserting the other spindle, push it through from the pulley side with the flats
in line with the set screw. Insert the spindle until the flats are under the set screws.
ALIGNMENT:
Fasten a 6" rule or other thin metal straight edge to the saw spindle in place of a saw
(between saw retaining screw and spindle end) with the end of the rule hanging down sev-
eral inches. Align the edge of the rule with the point of the center support and tighten the
saw spindle in this position with the 2 set screws.
