Adjusting Lower Wheel
Only do this procedure if you cannot make the wheels
coplanar with the tracking knob or by shimming the upper
wheel. Make sure the upper wheel is adjusted as close as
possible to being coplanar with the lower wheel before
beginning. Do this procedure with the blade fully ten-
sioned.
To adjust the lower wheel, do these steps:
1. DISCONNECT BANDSAW FROM POWER!
2. Loosen the jam nuts on the lower wheel adjustment
hub (see Figure 77).
3. Loosen one tilt adjustment bolt, then tighten the
opposing bolt approximately an equal amount.
4. Check the wheels with the coplanarity gauge, then
adjust the lower wheel at the hub as needed until it
is parallel and coplanar with the top wheel.
5. Tighten the jam nuts to lock the tilt adjustment
bolts in position.
