INSTALLING AND FITTING YOUR INSERT
- Remove riving knife (RK) and lower the blade completely.
- Place insert in throat opening with finger hole towards operator and starter pocket located over blade. Back end of insert must be placed in first, allowing anti-lift lug to slide under the cast iron ledge. Insert should be resting on TOP of the 4 leveling screws, just like the original factory insert is designed to do.
- Adjust leveling screws (through access holes provided) until insert is table and flush with table top.
- Back out the adjusting screw to achieve a fit which is snug, yet removable. Note: This insert does NOT utilize the magnet located in the front of your throat opening. This insert is held in place by lateral friction once the adjusting screw has been backed out.
CUTTING THE BLADE SLOT (KERF)
- Check that insert is fitted properly and that the blade is clear.
- Fully cover the insert with a board, and clamp at each end to the table saw top.
- Reconnect power to saw. Switch on, slowly and cautiously raise blade up, to cut its way through the insert. KEEP HANDS OFF OF TABLE TOP, STAY CLEAR AND WEAR GOGGLES.
- Raise blade to maximum desired height at this time.
- Lower blade, turn off saw, and remove board.
- RIVING KNIFE (RK): To accommodate the RK, you will need to finish cutting out the optional pre-routed RK slot, using a saw or router. This becomes simple and extension of the blade slot.
IMPORTANT TIPS FOR USE
- Only recommended for use with carbide tipped cutters.
- DADO BLADE - Use same procedures outlined above, but use additional caution due to excessive material being machined from insert during the slotting procedure.
- Under certain condtiions, an undesirable scraping noise may be generated by your saw blade. Planer type blades and/or excessive arbor run-out, and/or blade distortion, may be causing intermittent contact with the insert slot. To remedy this, remove the insert and slightly widen the slot using a file or sanding paddle.
- Ideally, a separate insert should be used with each blade, dado stack, or angle setup. This will insure a true "zero-clearance" effect and give you maximum benefit from your inserts.
