DRILL HOLES IN THE ½” BLACK SUB‐PLATE FOR THREADED INSERTS

1. Disconnect power. Remove the chip extractor and raise head.

2.  N‐FEED SIDE ‐ Using (1) PPG‐12‐FIN Brackets as a guide, place the bracket on the sub‐plate evenly spaced 1‐1/2” away from the infeed side of head casting, with the edge of the bracket lined up with the post‐side of the guide plate.
   NOTE: The yellow dotted line represents PPG Bracket Position, this is important if using an alternave sized sub‐plate. Align the in‐feed & out‐feed PPG Brackets with the pressure screws on the post side of the molder.

3. Use a metallic marker (or any pen that can make visible marks on a black sur‐face) to create a guide mark in the center of the each hole on the bracket.

4.  OUT‐FEED SIDE – Repeat Step #2 & #3 for the out‐feed bracket.

5. Remove the sub‐plate from the molder and place on an even, flat surface to allow  space  to  drill  the  holes.  Use  a  transfer  punch  and  hammer  to  make  a prick punch on each guide mark (4).

6. Using an 11/32” drill bit, drill all (4) holes through the sub‐plate, making sure to drill straight through to the other side.

7. Use a medium chamfer drill bit to chamfer the holes.

8. Using  a  6mm  Allen  Wrench  or  6mm  Hex  Head  Insert  drill  bit,  screw  in  the  PPG‐24 threaded inserts until they are flush with the surface of the sub‐plate. Attach sub‐plate to molder base.

ATTACH PPG BRACKETS & ROLLER ASSEMBLY

1.  With the machine off, bolt knives to arbor, set your guides to your sized stock, ghten adjusting handles.
2. Attach (1) PPG Bracket to the in‐feed side sub‐plate using the PPG‐23 screws.
3. Repeat Step #2 on the out‐feed side of the sub‐plate.
4. Attach the Roller Assembly to the bracket by feeding the bolt with weld nut already applied up through the opening of the bracket. Weld nut should be held tight to the inside‐top of the bracket, then screw on the knob.

NOTE: Height adjustments will be made in the next step.
