Upper Bearing Guides
Refer to Figures 47, 48, 49.
1. Disconnect machine from power source.
2. Blade must already be tensioned and
tr ac k ing properly.
3. Loosen thumb screw (A, Figure 47) and
move guide block by turning knob (B) so
that the front of the guide wheels (C) are
just behind the gullet (curved area at base
of tooth) of the blade, as shown in Figure
48. T his distance i s usuall y about 0.016” (or
1/64”).
4. Tighten thumb screw (A, Figure 47) .
5. Loosen the socket screw (D) and turn the
screw (E) on each guide wheel to m ov e the
guide wheels about 0.004” from the blade.
(A quick way to set this distance is to place
a crisp dollar bill, which is approximately
.004” thi ck, bet ween guide wheel and bl ade,
and m ov e the guide unt il it just contacts the
bill.)
6. Tighten socket screw (D) when adjustment
is satisfactory.
Thrust Bearing
The thrust bearing (F, Figure 49) supports the

(or 1/64”) behind the blade. You can use a
feeler gauge to set this distance, or simply
place a crisp dollar bill folded twice (four
thicknesses) between t he thrust bear ing and
the blade. (A dollar bill is approximately
0.004” thick, so four thicknesses provides
the nec essary distanc e.)
8. Tighten thumb screw (G, Figur e 50) .
