OPERATION

ROUGH CUTTING A DADO

See Figures 42 - 43.

Using a wood chisel and the depth guide, it is possible to make a rough dado cut. The marks on the depth guide are to be used for reference only. Always make a practice cut on scrap wood.

To make the cut:

Unlock the slide lock knob.

Raise the saw arm to its full height.

Using the marks on the depth guide, set the blade to the correct cutting depth.

With the saw off, pull the saw arm forward. Turn the saw on (let blade reach maximum speed), then push the blade down on top of the workpiece then back toward the rear of the saw to make a cut.

Cut two outside grooves in the workpiece.

Using a wood chisel, remove the material between the two outside grooves.

USING AN AUXILIARY FENCE

See Figure 44.

Certain unusual cuts may benefit from a thicker miter fence (auxiliary fence) due to the size and position of the workpiece. The holes provided in the miter fence are there for just this purpose. The miter fence holes are used to secure the auxiliary fence which requires a piece of wood 1/2 in. thick, 4-1/4 in. high, and 23 in. long to make.

NOTE: The auxiliary fence can only be used when the bevel is set at 0˚. When making a bevel cut, the auxiliary fence MUST be removed.

To attach the auxiliary fence to the saw:

Place the wood against the miter fence and mark the hole location from behind the fence using a pencil.

Drill holes through the wood then countersink the holes on the front of the wood.

Secure the wood to the miter fence using flat head screws.

With the miter table set at 0˚, make a complete cut through the auxiliary fence to create the blade slot.

NOTE: Check for interference between the auxiliary fence and the lower blade guard. Correct any interference before proceeding.
