— If the wheels are coplanar (Figure 116,
A), the straightedge will evenly touch the
top and bottom of both wheels.
— If the wheels are not coplanar (Figure
116, B), place the straightedge on the
lower wheel first (ensuring that it touches
both the top and bottom rim), then adjust
the upper wheel tracking knob to make the
upper wheel coplanar and parallel with the
lower wheel.
— If the straightedge does not touch both
wheels evenly, the upper wheel needs to
be shimmed (Figure 116, D) or the lower
wheel needs to be adjusted (Figure 116,
C).
Shimming Upper Wheel
1. DISCONNECT MACHINE FROM POWER!
2. Make sure the top wheel is adjusted parallel
with the bottom wheel.
3. With a straightedge touching both points of
the wheel that does not need to be adjusted,
measure the distance away from the wheel
that is out of adjustment (see Figure 115).

Figure 115 Determining distance needed to
shim upper wheel.
4. Remove the blade from the saw, then remove
the wheel that needs to be shimmed.
5. Determine how many shim washers you need
to compensate for the distance measured in
Step 3 and place them on the wheel shaft.

Install the wheel, the original washers, the
securing screw, and the blade.
7.
Tension the blade, then check the wheels
with the coplanarity gauge. Wheel coplanarity
changes as the blade is tightened, so it is
best to check the wheel alignment when the
blade is tensioned as it would be for normal
operations.
