CUTTING VERTICAL BOARDS See Figures 16- 17. • Unplug the biscuit joiner. • Loosen the locking knob and set the fence angle at 0°. • Set the fence height at the desired dimension on the scale by rotating the height adjustment knob. • Retighten the locking knob. • Select the correct depth of cut setting for the biscuit size you plan to use. • Clamp the workpiece securely. • Cut each slot at the marked centerline intersection. • Place the biscuit joiner on a vertical board and align the indicator marks on the base assembly with the centerline on the vertical board. • Place a straight piece of wood on the vertical board and securely clamp it flush against the base assembly. This piece of wood is used for a fence or guide. It must be square with the sides of the vertical board and parallel with the centedine. • Align the centedine on the bottom of the base assembly with marked intersection for biscuit slot. • Plug the biscuit joiner into the power supply and prepare to cut the slot. • Depress the switch trigger to turn on the biscuit joiner, then push it down to extend the blade into the wood. • When the base assembly bottoms out against the depth of cut adjustment knob setting, pull back, releasing pressure on the spring. The blade will retract from the biscuit slot. • Repeat this procedure for cutting all required slots in vertical boards. • Once all slots have been cut, place a biscuit in each joint and dry-assemble the workpieces. Make sure each joint lines up and fits. • Finally, disassemble the workpieces and place a bead of glue in each slot. Also, spread a bead of glue over the entire surface of the joint. Reinsert the biscuits and assemble the workpieces. • Clamp the workpieces together until the glue sets up.
