10.9 Spindle adaptor
1. Open side door, and place a 10mm wrench on
flat indents of motor spindle (A, Figure 10-5).
2. Insert chuck key into hole to use as leverage to
unscrew chuck (B, Figure 10-5) while holding
spindle stationary. Remove chuck from spindle.
3. Thread adaptor (C, Figure 10-5) onto motor
spindle (A, Figure 10-5). Tighten using 10mm
and 14mm wrenches respectively on flat sides
of motor spindle and adaptor.
4. Thread chuck onto adaptor. Tighten using
14mm wrench on motor spindle flats and chuck
key in chuck.

10.10 Chisel and bit adjustment
Note: Chisels and bits are available as optional
accessories. See sect. 12.0.
Chisels are extremely sharp.
Use great caution when handling to prevent
personal injury.
1. Insert chisel bushing with hole facing forward
(toward operator). See Figure 10-6. Tighten
screw just enough to hold chisel bushing in
place.
2. Insert bit into chisel, and use a block of wood
to push chisel upward as far as possible into
head. Then lower chisel approximately 1/16” to
3/16”. This may vary depending upon type of
wood. Table 2 shows general guidelines for
distance between points of chisel and bit point.
3. Tighten screw to secure chisel in place.
4. Push bit upward through chisel as far as it will
go into chuck. Lock bit in place using chuck
key.
5. Loosen screw and push chisel up against
bushing, then tighten screw. This should
provide the proper distance between the points
of chisel and bit.
6. IMPORTANT: Set the slot in side of chisel to
the left or right if 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 chisel slot is releasing chips
into the already-cut part of the workpiece (see
Figure 11-1).
