Installing Chisel and Auger
Referring to Figure 6:
1. Open
door
(A).
2. Swing
two
bushing spacers
(B) away from the
head
(C).
3. Loosen
the
lock screw
(D).
4. Insert the chisel
bushing*
(E) into the
head
(C),
lining up the
hole
(F) with the
lock screw
(D).
5. Set the
lock screw
(D) so the
threaded end
extends into the
hole
(F) of the
bushing
(E),
holding it in place. The bushing should still
have about 1/4" of vertical travel margin.
The
chisel to auger clearance (see Figure 5)
is the
vertical clearance between the auger and chisel.
When assembled, the proper
chisel to auger
clearance
is dependant on the chisel size and the
position of the chisel (adjustable) with respect to
the auger (which is fixed). The position of the
chisel is set with spacers described in the following
steps.
6. Position
spacers
(B) so they rest against the
bushing above the
lip
(J).
Number of spacers to use:
For chisels 1/2" or less – use the
upper spacer only
For chisels greater than 1/2" – use
both spacers
Chisels are extremely sharp.
Use extreme care when handling to prevent
personal injury.
7. Insert
the
auger
(K) into the
chisel
(L). Then
insert the assembly through the bushing (E).
Using gloves or a block of wood, press up on
the auger as far as it will go. The shank should
slide into the opening in the bottom of the
chuck (M).
8. Using the chuck key, tighten the
chuck
(M) to
secure the
auger
(K).
9. Move the
spacers
(B) away from the
bushing
(E), push the chisel
and
bushing
up
against the
head
(C); then tighten the
lock
screw
(D).
Hint:
Set the
slot
in the side of the
chisel
to the
left
or
right
if the workpiece is to be moved laterally
and
front
or
back
if it is to be moved from front to
back. The workpiece should be moved so that the
slot
in the chisel is releasing chips into the
already
cut
part of the workpiece (see Figure 13).
*
Only if changing bushings. The 701 Mortiser comes with the
5/8" bushing already installed.
Figure 6
Note:
This would be a good time to make sure that
the chisel is parallel to the workpiece. See the
Chisel Parallel to Workpiece
section.
