Blade guide adjustment
Overview
The blade guide assembly consists of two roller guides (bearings) po
-
sitioned on each side of the blade to provide blade stability. A third
guide (thrust bearing) is positioned behind the blade to provide blade
support.
There are two blade guide assemblies – an upper assembly (Figure 25)
and lower assembly (Figure 26).
Adjustments are performed in the same manner for each assembly.
Each assembly must be adjusted in turn using the adjustment proce-
dures outlined below
Thrust bearing adjustment
Refer to Figures 25 and 26:
Note:
Blade must already be tensioned and tracking properly. Dis
-
connect machine from power source. For the upper thrust bearing,
loosen thumb-screw (A, Figure 25). For the lower blade guide, loosen
setscrew (A, Figure 26) with the 3mm hex wrench provided. Slide the
adjustment shaft (C) so the blade is positioned in the middle of the
thrust bearing (D).

lower blade guides
The thrust bearing (D) is mounted on a concentric shaft (C). When the shaft is rotated, the relative position of the bearing to the back of the
blade can be changed. Rotate the adjustment shaft (C) so the thrust bearing (D) just clears the back of the saw blade. Tighten thumbscrew/
setscrew (A).
NOTE: If a blade is being replaced with a new one of a different size, the adjustment described above may fall out of range and further adjust
-
ment may be required as follows: Loosen the socket head screw (E, not visible) with a 10mm wrench and adjust the entire assembly back or
forth to just clear the back of the saw blade. Tighten screw (E), then fine tune the adjustment by repeating the first part of this step. Secure
the thrust bearing (D) by tightening the thumbscrew (A, upper guide) or setscrew (A, lower guide).
Guide bearing adjustment
Refer to Figures 25 and 26:

-
connect machine from power source. For upper blade guide, loosen
two thumb-screws (F). For lower blade guide, loosen two setscrews (F)
with the 3mm hex wrench provided. Slide adjustment shaft (G) to po
-
sition each guide bearing (H) approximately 1/16" behind the gullets of
the saw blade. The guide bearing (H) is mounted on a concentric shaft.
When the shaft (G) is rotated, the relative position of the guide to the
blade can be changed. Rotate each adjustment shaft (G) to position
the guide bearings (H) within 1/32" of the saw blade. Secure the guide
bearings (H) by tightening thumbscrews (F, upper guide) or setscrews
(F, lower guide).
Miter gauge adjustment
Refer to Figure 28:
To adjust angle of miter gauge, loosen handle (J) and rotate gauge
body. Tighten handle. Place miter gauge into table slot and use a
square to verify that 90-degree setting on scale is 90-degrees to slot.
Adjust pointer (K) if necessary.
