1 - General
1.1 - General safety regulations
-The wheel balancer may only be used by duly authorized and trained personnel.
- The wheel balancer must not be used for purposes other than those described in the instruction manual.
- The wheel balancer must not be modifi ed in any way except for those modifi cations made
explicitly by the manufacturer.
- Do not remove the safety devices. Any work on the machine must be carried out by specialised personnel
only.
- 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 fl ange.
- The machine operator must not wear clothes with fl apping parts. Do not allow unauthorized personnel to
approach the wheel balancer when the cycle is running.
- Avoid placing objects in the base which could impair the correct operation of the wheel balancing machine.
- Before disassembling the weight shelf, remove the guard (see specifi c instructions)
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 cars, light commercial vehicles or motorcycles weighing less than 75 kg.
It can be operated in a temperature range of 0° to + 45° C.
The following functions are provided: ALU-S; SPLIT; Unbalance optimisation; Autodiagnostics; Autocalibration.

3 - Startup
3.1 - Anchoring
The machine can operate on any at non resilient oor.
Make sure that the machine rests solely on the three support points provided (Fig.2a).
It is advisable to secure the system to the ground using the speci c feet (Fig. 2a). if the machine is
continually used with wheels weighing over 35 kg.
3.2 - Electrical connection
The machine is supplied with a single-phase mains cable plus earth (ground).
The power supply voltage (and mains frequency) is indicated on the machine identi cation plate and cannot be
changed.
Connection to the mains must always be made by expert personnel.
The machine must not be set up without proper earthing.
Connection to the mains should be through a slow acting safety switch rated at 3 A (230V) or 8 A(115 V).
See enclosed diagram.
3.3 - Flange mounting
3
The wheel balancer is supplied complete with cone
anges
for xing wheels with a central hole. Other optional
anges can be mounted:
a) Remove the threaded end-piece A after unscrewing
the screw B.
b) Mount the new ange (see attached sheets).
Note: CAREFULLY CLEAN THE COUPLING
SURFACES BEFORE PERFORMING ANY
OPERATION.
3.4 - Wheel guard assembly and adjustment (optional)
Fix the components to the base as described in the attachment “WHEEL GUARD ASSEMBLY SEQUENCE” at
the end of the manual.
N.B.: Do not lean on the guard during the wheel balancing cycle.
3.5 - WD spacer (option)
When balancing very wide wheels (9”), there is not enough space to turn the distance gauge. To move the wheel
away from the machine side, t the WD spacer on the ange body and secure it with the standard issue nuts. When
centring the wheel with cone from the inside, mount the DC spacer to obtain spring thrust.
