Pulling down on the handle can be difficult
on some woods. However, NEVER use a
cheater pipe or handle extender on the
handle. You could break the hand lever and
be seriously injured.
7.
Turn power ON. Use hand lever to feed mor-
tising chisel into test piece.
— Feed rate must be fast enough to prevent
tip of auger from burning, but slow enough
to prevent motor from stalling. This speed
will vary depending on wood type, mois-
ture content, and frequency of chip clear-
ing from mortise.
— When cutting deep mortises, make a 1"
deep cut, then back off and allow chips to
clear before cutting deeper.
Note: With some chisels, noise and smoke
are normal, but we recommend using a small
amount of lubrication on augers (not chisels)
to keep this to a minimum. See Page 28 for
more information on lubricating augers.
8.
Once desired depth is achieved, move hand
lever to return headstock to highest position.
Test piece should be held in place by hold-
down.
9.
Turn power OFF.
10. Inspect placement of mortise cut on test
piece. If necessary, adjust machine until
desired mortise placement is achieved.
11. Cut mortise in final workpiece.
NOTE: When making multiple cuts to create
a rectangular mortise cut, follow sequence of
cuts as shown in Figure 28. Position chisel
over the center of cuts 5, 6, and 7, since these
only use part of chisel.
