Wheel does not spin automatically.
1. Lowering the switch guard does not activate a wheel
spin.
•
Check if the switch is mechanically activated by
lowering the guard.
2. Electrical malfunction.
•
Call the Service team.
Gauge arm input differs from rim dimension stated
on rim or tire.
1. Did you position the gauge arm correctly?
•
Refer to Chapter 5.3.1.
2. Check the offset detected by the gauge arm against
that on the gauge rod scale.
•
Refer to the scale on the gauge.
•
If not identical, proceed with step 4.
3. Check the diameter of the spot on the rim where
the diameter has been measured.
•
If not identical, proceed with step 4.
4. A calibration is required.
•
Have the gauge arm calibrated.
Balancing results are inconsistent.
1. The balancer may not be installed properly.
•
Make sure the unit rests on its 3 feet only.
•
Make sure the floor is not relaying shocks from e.g.
passing trucks to the unit.
2. The wheel may be mounted incorrectly.
•
Check the stub shaft, cones and adapters for play.
•
Use an adapter plate to eliminate play.
•
Perform a Measuring Unit calibration.
3. The electronics are faulty.
•
Call the Service team.
A mode, display segment or indicator is
continuously shown on the display.
1. A “brown out” (power dip) may have occurred.
•
Switch off the unit.
Wait for 20 seconds, switch on the unit.

Balancing results are inconsistent.
1. The balancer may not be installed properly.
•
Make sure the unit rests on its 3 feet only and is
not rocking.
•
Make sure the floor is not relaying vibrations from
outside sources. The electric pick-ups are extremely
sensitive. Any induced vibration will be detected and
may cause balancing errors.
2. The wheel may be mounted incorrectly.
•
Check the stub shaft, cones and adapters for play.
•
Use an adapter plate to eliminate play.
•
Perform a Measuring Unit calibration.
