FIGURE 6
CAUTION: Do not have the chisel slot against the blind end of the mortise, as the chips
will not be able to clear the chisel. This can cause overheating and possible breakage of
chisel or bit.
When cutting deep mortises, make the cut in several stages of approximately 1" each, to allow
chips to clear. To prevent breakout at the back of the workpiece when cutting through mortises,
use a piece of scrap material under the workpiece as support.

MAINTENANCE
The Mortiser requires only minor maintenance, such as cleaning and lubrication and routine
adjustment and sharpening of the chisel and bit.
Dust the machine down after each use and, as necessary, use light applications of oil or grease
to lubricate linkages, moving parts, etc.
SHARPENING CHISEL & BIT
The chisel and bit should be kept sharp for best performance. Blunt edges will give inaccurate
mortises and can lead to overheating and breakage to chisel or bit. If chisel and bit are badly
worn and become difficult to sharpen, they should be replaced.
1. Sharpen the bit by using a small, smooth file, following the original shape of the bit. File the
inside edge of the spur, the sides of the brad point, and the cutting edge inwards toward the flute
of the bit. See Figure 7.
