9. Make further adjustments as needed, with
the saw disconnected from power.
Upper Blade Guides
The bearing guides should be set so that
contact between blade and guides will occur
only when the blade is under pressure from a
workpiece. To adjust the upper bearing guides
for proper blade control, proceed as follows.
Refer to Figures 28 through 31.
1. Disconnect machine from power source.
2. Blade must already be tensioned and
tracking correctly. Place quick tension lever
in “Full Tension” position.
3. Lower the guide post until the upper guide
bearings are a few inches off the table. (The
reason for this will be shown later under
“Guide Post Parallelism.”)
4. Loosen the locking screw (A, Figure 28).
5. Move the entire guide bracket by rotating
the knurled knob (B) until the front of the
guide bearings are about 0.015” (1/64”)
behind the blade’s gullet (curved area at the
base of the tooth). See Figure 30.
6. Tighten the locking screw (A) to secure this
position.
7. Loosen the locking screw (C) for one of the
guide bearings.
8. The guide bearing rotates on an eccentric
shaft. Adjust the guide bearing by rotating
the knurled knob (D) until the guide bearing
is approximately 0.004” from the blade. A
quick way to achieve this spacing is by
placing a single thickness of a crisp dollar
bill (a dollar bill is approximately 0.004”
thick) between blade and guide bearing.
See Figure 31. Adjust the guide bearing
until it just lightly grips the dollar bill.
NOTE: Do not force the guide bearing
against the side of the blade. It should only
make contact with the blade when there is
pressure from the cutting operation.
9. Tighten locking screw (C) and remove dollar
bill.
10. Repeat process for opposite guide bearing.
Upper Thrust Bearing
Refer to Figures 29 and 32:
The thrust bearing prevents backward deflection
of the blade during cutting. The thrust bearing
has three options for stabilizing the back of the
blade (see Figure 32).
