ATTACHING THE WORKPIECE HOLD-DOWN - ALL UNITS
1. Attach the vertical shaft (X) Fig. 15 to the fence, using the supplied wrench (H).
NOTE: Place the flat on the shaft (X) toward the rear of the drill press.
2. Position the workpiece hold-down (I) Fig. 15 over the shaft (X) and tighten the thumb screw (J) against the flat on
the shaft.
3. Insert the two guides (K) Fig. 16 into the pre-drilled holes in the fence (A) and secure them in place using the two
thumb screws (L).
NOTE: You can cut mortises in workpieces of 3/4" or thicker on the 17-900 16-1/2" drill press.
NOTE: If you are mortising to the center of a workpiece less than 3/4" thick, you can attach a wooden auxiliary fence
to the fence (A) Fig. 17 with screws through the holes (M).
INSTALLING THE CHISEL AND BIT
Disconnect the machine from the power source.
1. Position the chisel (A) Fig. 18 in the chisel holder (B) so that the upper face of the chisel (D) is approximately 1/32"
below the bottom edge of the chisel holder (B). Make sure that the chip ejection slot (E) faces toward either the left
or right of the drill press to provide efficient chip removal, eliminate excessive heat build-up, and lengthen the life
of the chisel and bit.
2. Tighten the thumb screw (C).
3. Push the bit (F) Fig. 19 up through the chisel (A) as far as it will go and tighten the drill press chuck.
4. Loosen the thumb screw (C) Fig. 19, and move the chisel (A) up against the bottom edge of the chisel holder (B).
5. Tighten the thumb screw (C).
NOTE: If the noise level increases during operation, re-center the chisel holder using the alignment pin as previously
described.
