if the wheels are coplanar (figure 109, A),
the straightedge will evenly touch the top
and bottom of both wheels.

if the wheels are not coplanar (figure 109,

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 lower wheel needs to
be adjusted (

figure 109, c) or the upper

wheel needs to be shimmed (

figure 109,

D).

Shimming upper Wheel

1. disConneCt BandsaW 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 110).

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.

6. replace the wheel, the original washers, the

securing screw, and the blade.

7. tighten 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.)

8. When the wheels are coplanar, place a mark

on each wheel where you held the straight-
edge. this assures repeated accuracy every
time you adjust your wheels.

Note: When wheels are properly coplanar,
the blade may not be centered on the crown
of the wheel, but it will be balanced.
