Check
1. Press and respin. Check PHASE in MACHINE SELF-TEST
“Green Screen”, if 180 deg diff., recalibrate & check piezos.
2. Check encoder adjustment and operation. (clearance .020” to .035”)
3. Check motor operation.
4. Check belt tightness.
5. Check hub nut tightness.
6. Replace the main PCB.
1. Press and respin. Check PHASE, VCO (dynamic), VCI (static) in
MACHINE SELF-TEST “Green Screen”.
2. Check the piezo pick-ups connection. (electrical & mechanical)
3. Check the balancer spindle connections.
4. Mount a wheel having a known unbalance (lower than 3.5oz or 100
grams) and check the balancer readings.
5. Replace the PC board.
A.) Follow screen instructions for “heavy side” down balancing to bring
wheel unbalance into range and then balance normally.
B.) Follow instructions 1 thru 5 above.
1. Wheel too light - not enough inertia. Use heavier wheel.
