OPERATION
WARNING: To prevent serious injury, make sure all the warnings and instructions have been read and
understood before operating this tool.
OPERATING THE MORTISER
1. Draw cutting guides on the surface of your workpiece. With
the mortiser switched OFF, pull down the handle to lower
the chisel. Adjust the position of the workpiece so the chisel is
aligned with the cutting guide.
2. Adjust the fence so it is right against the back of the work-
piece. Set the depth stop to your desired cutting depth (see
page 14).
3. Install the hold-down clamp (Fig. 16 - 1) to prevent the work-
piece from lifting off the table; make sure you can still slide the
workpiece below the hold-down clamp. Tighten the hold-down
knob (Fig. 16 - 2) to lock the hold-down clamp in place.
TIP: You can place a block of wood between the top of the headstock and the top plate above the guide columns
to shorten the spindle travel distance for more efficient cutting.
4. Turn ON the mortiser. Wait a few seconds to let the motor reach full speed before feeding the bit into the
workpiece.
5. Make the first plunge cut. Go slow and give the chisel plenty of time to cut in and extract the chips. You may
want to plunge in several passes.
6. To make a long rectangular mortise, move the workpiece slightly more than a chisel width along the fence and
make the second cut. Spacing out the cuts allows the chisel to be supported by the wood equally on all four sides.
If the chisel is only support on three sides, it may want to wander in the direction of the open end and create a
bend.
7. After the spaced cuts have been made along the width of the rectangle, go back for a second round of cutting
to clear out the spaces between cuts. The resistance will be lower this time, as there is only wood on the front and
back of the chisel.
8. Finally, make a third pass to clear out all waste and achieve a clean cut.
9. Turn off and unplug the machine. Wait for all moving parts to stop completely before cleaning, making adjust-
ments or leaving the work area.
