FASTENING MACHINE TO SUPPORTING SURFACE
If during operation there is any tendency for the mortiser
to tip over, slide or walk on the supporting surface, the
base must be secured to the supporting surface with
fasteners (not supplied), through the two holes (A) Fig.
16, located in the mortiser base.

the right or left, never to the front or rear. The opening
allows chips to escape during operation.

3. Loosen screw (D) Fig. 21, and push chisel (B) up
through hole in head as far as possible. Then lower chisel
(B) 1/16" to 3/16" and tighten set screw (D).
IMPORTANT:
When inserting chisel (B) Fig. 22 into head, there must
be a space of 1/16" to 3/16" clearance (F) between the
bushing (E) and shoulder of chisel (B) as shown. This
assures having proper clearance between the cutting
lips of the bit and points of the chisel after the bit is
inserted into the chuck.
