Err.18 Unbalance measurement error. 1. Verify phase pick-up board function.
2. Check detection unit connections.
3. Verify machine earth/ground connection.
4. Mount a wheel with more or less known unbalance (less than 100
grammes) and verify the response of the machine.
5. Replace the computer board.
Err. 20 The wheel comes to a halt before comple-
ting positioning correctly. 1. Make sure that the wheel to be balanced is at least 10” in diame-
ter.
2. Verify the correct setting of wheel dimensions on screen.
3. Verify belt tautness.
4. For wheels less than 12” in diameter wheels: disenable the
eccentricity measurement procedure

plotting procedure error. Perform a new eccentricity measurement.
9 - ROUTINE MAINTENANCE (see exploded drawings) (For non specialized personnel only)
Always disconnect the machine from the mains before carrying out any operation.
9.1 - Adjusting belt tautness
Remove the weight shelf
Slightly slacken the motor locking screws
Move the motor by acting on the rear and front thrust screws, keeping the motor axis parallel to the spindle axis
Lock the motor screws and make sure that the belt does not oscillate in movement (especially from side to side)
when braking.
9.2 - Replacing fuses
Remove the weight holder shelf to gain access to the power supply board where the 4 fuses are located (
Exploded Drawings). If fuses require replacement, use ones of the same current rating. A fuse is also fi tted to the
braking transformer cable. If the fault persists, contact Technical Service.
9.3 - Air circuit maintenance
It is important to clean the compressed air fi lter regularly and make sure that there is suffi cient lubrication oil. The oil
bath must be 3/4 full; to top-up, use average viscosity mineral oil (30° cST to 40° WAIRSOL type LXOL). Normal oil
fl ow is one drop every 10 operations.
N.B. DRAIN FREQUENTLY ANY CONDENSATE BUILT UP IN THE FILTER BOWL VIA RELATIVE
VALVE.
NONE OF THE OTHER MACHINE PARTS REQUIRE MAINTENANCE.
