1- GENERAL
1.1 - General safety recommendations
▪ The wheel balancing machine should only be used by duly authorized and trained personnel.
▪ The wheel balancing machine should not be used for purposes other than those described in the instruction
manual.
▪ Under no way should the wheel balancing machine be modifi ed except for those modifi cations made explici-
tly by the manufacturer.
▪ Never remove the safety devices. Any work on the machine should only be carried out by specialist person-
nel.
▪ Avoid using strong jets of compressed air for cleaning.
▪ Use alcohol to clean plastic panels or shelves (AVOID LIQUIDS CONTAINING SOLVENTS).
▪ Before starting the wheel balancing cycle, make sure that the wheel is securely locked on the adapter.
▪ The machine operator should avoid wearing clothes with fl apping edges. Make sure that unauthorized per-
sonnel do not approach the machine during the work cycle.
▪ Avoid placing objects inside the base as they could impair the correct operation of the machine.
▪ Correct head disassembly (also see exploded drawings): the weight-holder head is anchored to the bed on
the front side with snap-fi tting clips; on the rear side, it is secured by a safety screw accessed by removing
the control panel.
1.1.1 - Standard safety devices
▪ Stop push button for stopping the wheel under emergency conditions.
▪ The wheel guard is not compulsory since the balancing speed is less than 100 min
1.2 - Field of application
The machine is designed for balancing wheels of car, light commercial vehicles or motorcycle, weighing less than 75
Kg. It can be operated in the temperature range of 0° to + 45° C.
The following functions are provided: Double operator; ALUS; SPLIT; Unbalance optimization; Self diagnostics;
Self-calibration.

NOTE: DO NOT HOIST THE MACHINE USING DIFFERENT GRIPS
(See “Correct head disassembly” - paragraph: GENERAL SAFETY REGULATIONS)
3 - COMMISSIONING
3.1 - Anchoring
The machine can operate on any fl at non resilient fl oor.
Make sure that the machine rests solely on the three support points provided (fi g. 2a).
3.2 - Electrical connection
The machine is supplied with a single phase mains cable plus earth (ground).
The supply voltage (and mains frequency) is given on the machine nameplate. It cannot be changed.
Connection to the mains should always be made by expert personnel.
The machine should not be started up without proper earthing.
Connection to the mains should be through a slow acting safety switch rated at 3 A (230V) or 8 A (115V). See enclosed layout.

3.3 - Adapter mounting
3
A
B
The wheel balancing machine is supplied complete
with cone adapter for fastening wheels with central
bore. Other optional adapters can be mounted:
a) Remove threaded end piece A after backing off
screw B.
b) Mount the new adapter (see enclosed brochures).
NOTE: CAREFULLY CLEAN THE COUPLING
SURFACES BEFORE PERFORMING ANY
OPERATION.
3.4 - Wheel guard assembly and adjustment (optional)
a) Fasten the components to the base as illustrated in the specifi c exploded drawing.
b) The position of the wheel guard when closed can be adjusted with relative screw accessible at the back. Cor-
rect position is the one which keeps the tube exactly horizontal with the wheel guard closed.
c) Check that the microswitch is held down when the guard is closed.
Note: Do not lean on the guard during the wheel balancing cycle.
3.5 - Spacer WD
When balancing very wide wheels (9”), there is not enough space to turn the distance gauge. To withdraw the
wheel from the machine side, fi t spacer WD on the adapter body and secure it with the standard issue nuts.
When centring the wheel with the cone on the inside, fi t the DC spacer to obtain spring thrust.
