OPERATION

FLAT MITER JOINTS (Continued)

Depress the switch trigger and let the motor build to its maximum speed, then gradually push biscuit joiner forward 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. Blade will retract from biscuit slot.

Repeat this procedure for cutting mating slot and all required miter joint slots.

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. See Figure 16.

Clamp workpieces together until the glue sets up.

HOW TO MAKE EDGE MITER JOINTS

Unplug your detail biscuit joiner.

Place the pieces of wood to be joined on a level workbench as shown in figure 17.

Mark centerline of the joint on each board.

When making edge miter joints with workpieces that have different thicknesses, clamp securely to a workbench with the long sides up. This will assure that the outside surfaces will match. See Figure 18.

Set fence angle at 45°.

Slide the fence up or down until fence height is at desired setting.

Tighten height adjustment knobs securely.

Place your biscuit joiner on workpiece with the fence resting on the long side of workpiece as shown in figure 18. The front base should be against the mitered edge of the workpiece.

Recheck fence height setting to make sure it will not cut through the workpiece.

Align indicator mark on fence with the centerline on the workpiece. Make sure the front base is pressed flat against the mitered edge of the workpiece.

Plug your biscuit joiner into power supply and prepare to cut slot.

Depress the switch trigger and let the motor build to its maximum speed, then gradually push biscuit joiner forward to extend the blade into the wood.

When the base assembly bottoms out against the depth of cut adjustment knob setting, pull back releasing pres- sure on the spring. Blade will retract from biscuit slot.
