the head is lowered so the chisel rests on the
workpiece. The depth stop rod is
adjusted
using a measuring tape, to the desired
depth.
Figure 32
shows the chisel being
lowered until the chisel is even with a depth
line on the workpiece. The fence is adjusted
before and after the depth stop is locked.
4.
Carefully mark the outline of the mortise
on the workpiece. Align the fence and
workpiece so the chisel aligns with the mark-
ings.
See section on Fence Adjustments.
A
sacrificial board should be used under the
workpiece whenever through-holes are pro-
duced to minimize tear out and protect the
work table.
5.
Test the positioning setup with a piece of
scrap lumber of the same dimensions as the
workpiece. Position the hold down on top of
the workpiece and secure with cap screw.
Do Not mortise without a hold down.
6.
Turn the power ON.
7.
Lower the head by pulling the hand lever
down with your right hand. Be sure not to
feed the chisel too fast or too slow. Feeding
too fast can cause the drill bit to clog with
chips causing the motor to slow down and
overheat. Feeding too slow may cause exces-
sive heat, ruining the chisel. However, it is
normal for some discoloring of the chisel to
occur due to heat generated during use.
8.
When desired depth is achieved, move the
hand lever back to its original position. The
workpiece should remain in place as this is
done.
9.
Check the placement of hole on the test piece
and adjust the fence if necessary. Continue
with the actual workpiece when the desired
accuracy of placement is achieved.
10.
When making rectangular mortises, we rec-
ommend you follow the sequence of cuts
shown in
Figure 33.
Please note that cuts 5,
6 and 7 will only use a portion of the chisel
and so the chisel should be positioned over
the center of each space.
The chisel will become
hot during operation. Use
gloves or wait until chisel
has cooled before remov-
ing. Serious personal inju-
ry may occur.
