1 - Description of the wheel balancer

1.1 - General

It is an electronic wheel balancer with microprocessor designed for balancing wheels up to 200 kg in weight.
The controls and indicator devices are all mounted on the front panel.
The push button calibration system allows a sufciently wide range of adjustment to cater for wheels other than the
ordinary ones (motor cycles and racing cars).
Certain functions are available for wheels of unusual shape and for setting the optional functions of the wheel
balancer. The machine is equipped with a built-in pneumatic lift to facilitate mounting of large size wheels. The lift is
complete with a carriage running on castors with side bar having a dual function: ensuring operator safety and easier

axial displacement of the wheel.

1.4 - Recommendations

- Before starting to use the balancing machine, carefully read the operating instruction manual.

- Keep the manual in a safe place for future reference.

- Refrain from removing or modifying machine parts as this would impair correct operation. Please get in
touch with the Technical Service when needing repairs.

- Do not use 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 not wear clothes with apping edges. Make sure that unauthorized personnel
do not approach the balancing machine during the work cycle.

- Avoid placing counterweights or other objects in the base which could impair the correct operation of the
balancing machine.

- The balancing machine should not be used for purposes other than those described in the instruction

manual.

1.5 - Standard safety devices

- Low rotation speed.

- Stop push button for stopping the wheel under emergency conditions.

- The safety guard of high impact plastic is with shape and size designed to prevent risk of counterweights
from ying out in any direction except towards the oor. A microswitch prevents starting the machine if the
guard is not lowered and stops the wheel whenever the guard is raised.

- Protection system on LIFT control.

2 - Hoisting and installation

To hoist the machine, lever only on the base where the 3 support points are located. Never, under any circu­mstance, apply force to other points such as the spindle, head, side guard or accessory shelf.

Check that the balancing machine touches the oor at the three support points.
The machine does not require anchoring to the oor for correct operation.

N.B.: The model without LIFT with protection must always be secured to the ground to ensure stability. The standard
model with LIFT offers alternative options:

- Front wheel translation KIT

- Ground securing plate KIT

3 - Commissioning

3.1 - Electrical power supply

WARNING: The electrical connection must be made by specialized personnel. Connection to the single

phase mains must be made between phase and neutral, and never, under any circumstances,
between phase and earth (ground). Efcient earthing (grounding) is essential. The Manufacturer
declines all responsibility and warranty in the event of incorrect connection.

Before connecting the machine to the mains through relative cable, check that the mains voltage matches the one
shown on the nameplate at the back of the balancing machine. Rating of the electrical connection should be on the
basis of the machine electrical power consumption (see nameplate).

- The machine mains supply cable should be tted with a plug conforming to current regulations.

- It is recommended to provide the machine with its own electrical connection through a slow acting safety switch
rated at 4 A (230 V) or 10 A (115 V).

- When connection is made directly to the main control panel without using any plug, it is advisable to padlock the
main switch of the balancing machine in order to limit its use to authorized personnel only.

3.2 - Pneumatic connection

Connect the machine to the compressed air main. Do not use the machine if there is no pressure. Max. permissible
inlet pressure is 10 kg/cm2 (approx. 10 bar or 145 PSI or 1Mpa). Make the connection to the pressure limiting unit at
the back of balancing machine. The pneumatic circuit is designed to give the Lift considerable “exibility” of move­ment in any position of its stroke; thanks to this the wheel position can be adjusted according to requirements with
minimum manual effort.

3.2.1 - Pressure adjustment for spin and braking device

Use relative knob on the compressed air preparation unit to adjust the pressure. Average pressure setting is 4 to 5
kg/cm2 (approx. 4 to 5 BAR or 60 to 75 PSI or 0.4 to 0.5MPa).
N.B. An excessively high pressure could led to rapid wear on the rubber on the driving pulley.
Lubrication is essential for correct machine operation. Oil ow rate is adjustable via relative screw on the oil tank.
Tighten or loosen the screw until a drop of oil falls per every 10 consecutive spins.

CAUTION! Only use mineral oil with average viscosity (30 cST at 40°C - WAIRSOL, LXOL grade).

4 - Assembly

4.1 - Adapter mounting

3

The wheel balancer is supplied complete with cone
type adapter for fastening wheels with central bore.
Other optional adapters can be mounted:
a) Remove threaded end piece A after backing off
screw
b) Mount the new adapter (see enclosed
brochures).

4.2 - Wheel mounting

The wheels should be fastened with one of the numerous adapters builded by The Manufacturer (see enclosed
brochures). N.B.: Incorrect centering inevitably causes unbalance.

4.3 - Guard mounting and adjustment (option)

a) Fasten the components to the base as illustrated in specical exploded drawing.
b) The positions of these guards can be adjusted using the special screws accessed from inside the main support.
c) Check that the microswitch is held down when the guard is closed.
d) Adjust the angular position of microswitch control.

6.1 - Automatic measurement

Two types of measurements are provided, namely:

- STANDARD WHEELS, valid also for correction modes ALU - 1-2

- ALU - S, very useful for alloy rims of special shape where ALU 2 does not guarantee sufcient approximation.

6.1.1 - Standard wheels

- Move the gauge into measuring position as shown in g. 4. While the gauge is being displaced, the symbol shown in

g. 5 appears on the display in movement thus indicating that the gauge is not in a steady position.

- Hold the gauge still in position for approx. 2 sec.

6

- Indication of successful memorization is displayed as shown in g. 6.

- Return the gauge to position 0.

- Manually preset the diameter and width dimensions as described in section MANUAL PRESETTING.

N.B.: If the symbol of g. 5 or 6 appears on the displays, the gauge is not in position 0. It is not possible to use the

control panel, not even for making a balancing spin. Check the position.

N.B.: dE by default = 0.8 dI

(keep ALU pressed)

N.B. When dI is reselected, the system automatically sets dE = 0.8 dI.
The system automatically calculates the distance between the centres of gravity of the weights by
considering them approx. 14 mm wide. To display the unbalance regarding the preset dimensions, press

button ; if a spin has already been made, the system automatically recalculates the unbalance;

otherwise press the push button for a new spin.

6.3 - Presetting with gauge extension

The extension increases the distance measuring range of the gauge by 10 cm (g. 12).
Proceed as follows:

- Insert the extension on the distance gauge.

- Measure the distance as already described in the above procedures.

- After reading value “a” on the scale, return the gauge to 0 and preset the value “a + 10” in manual mode.

- Preset the diameter and width in manual mode as illustrated in g. 10:

6.4 - Double operator program

This program allows memorizes the dimensions of two types of wheels.
Thus two operators can work simultaneously on two different vehicles using the same balancing machine.
The system always memorizes two programs regarding the last two spins carried out with the various preset
dimensions.
When the machine is switched on, the programs are the same.

To change the program, press

Display, Program 1:

DIMENSIONS: as shown in g. 10a/b/c
UNBALANCE: as shown in g. 13-14

Display, Program 2:

unit of measurement = grams unit

of measurement = ounces

N.B.

- Each time the dimensions are changed and a spin is performed subsequently, the system saves Program 1 in Pro­gram 2 while the current dimensions are saved in Program 1. In this way, the programs regarding the last two types
of wheels balanced are always available.

- This mode of operating is also valid for dimensions regarding the special “ALU-S” function.

7.3 - Minimization of static unbalance

INTERNAL LIMIT, COUNTERWEIGHT

- When using the normal commercially available weights, with pitch of 5 in every 5 g, there could be a residual static
unbalance of up to 4 g. The damage of such approximation is emphasized by the fact that static unbalance is
cause of most of the disturbances on the vehicle. The computer automatically indicates the optimum entity of the
weights to be applied by approximating them in an “intelligent” way according to their position. (Pitch 5 grams/0.25
ounce for cars, 50 grams/1 ounce for trucks).

- Press to display the actual unbalance (Pitch 1 gram/0.1 ounce).

- The instruments indicate “0” for unbalance less than 5 grams/=.4 for cars and 50 grams/2 ounces for trucks; to

display the residual unbalance press .

) of the unbalance compared to the actual wheel

situation.

- LH display: actual static unbalance which can be
reduced by wheel-rim rotation.

- This function serves to reduce the amount of weight to be added in order to balance the wheel.

- It is suitable for static unbalance exceeding 30 g.

- In many cases it is also possible to improve the residual eccentricity of the tyre.

- The operations described below should be carried out with great care in order to obtain the best results.

Press:

(Press if it is wished to cancel the
function).

- The display prompts the operator to rotate
the rim-tyre. Mark with chalk a reference sign on the
adapter and rim in order to ret the rim in the same posi­tion of the machine.
(Use scale on the spindle).

- With the aid of a tyre remover, turn the tyre on the rim
by 180°.

- Ret the rim on the adapter in the previous position.

RH display: possible percentage reduction (symbol

Turn the wheel under the outer LED’s light up:
mark the tyre in the 12 o’clock position.

In the same way, mark the rim corresponding to the
position indicated by the innermost LED’s.

- Make the two points to coincide.

- In this example, an 80% reduction of the static unbalance of 45 grams is achieved with a residual of approx. 9
grams.

8.1 - Visual wheel examination

In certain cases, it is considered appropriate to rotate the wheel with the guard open in order to check the
state of the tread.

- Press and with the other hand press .

- One complete measuring spin is performed. The function is disabled automatically at the end of the cycle.

WARNING! The use of this function is at the operator’s own risk and peril.

9 - Self-calibration

9.1 - Wheel balancer

For self-calibration of the machine, proceed as follows:

- Fit a medium-sized wheel with steel rim on the shaft. Example: 6" x 14" (± 1")

- Preset the exact dimensions of the wheel mounted.

CAUTION!! Presetting of incorrect dimensions would mean that the machine is not correctly calibrated, therefore

all subsequent measurements will be incorrect until a new self-calibration is performed with the correct
dimensions!

- Hold down keys

- Press

- Press

until the positioning LED’s
change from ashing into
steady.

- It is highly important to
avoid the wheel from
being knocked during
this spin.

- Add a 100 gram weight
(3.5 oz) on the outside in
any angular position.

- MACHINE CALIBRATED

- Remove the reference
weight and balance the
wheel as described pre­viously.

The values derived by the machine from the self-calibration cycle are automatically memorized in a special memory
which retains them even when the machine is switched off. Hence each time the machine is switched on again, it is
ready for correct operation. However, the self-calibration operation can be repeated whenever required or if there is

some doubt as to the correct operation of the machine.

9.2 - Automatic rim distance gauge

Press:

Shift the distance gauge to position “0” and keeping it quite still, press:

Shift the distance gauge to position “15” and keeping it quite still, press:

CORRECT CALIBRATION

- Return the gauge to rest position

- The wheel balancer is ready for operation

N.B. In the event of errors or faulty operation, the writing CAL P.O appears on the display: shift the gauge
to position 0 and repeat the calibration operation exactly as described above. If the error persists, contact
the Technical Service Department. In the event of incorrect input in the rim distance gauge calibration
function, press to cancel it.

10.1 - Inconsistent unbalance readings

Sometimes after balancing a wheel and removing it from the balancing machine, it is found that,
upon mounting it on the machine again, the wheel is not balanced.
This does not depend on incorrect indication of the machine, but only on faulty mounting of the
wheel on the adapter; i.e. in the two mountings, the wheel has assumed a different position with
respect to the balancing machine shaft centre line.
If the wheel has been mounted on the adapter with screws, it could be possible that the screws have not been cor­rectly tightened, i.e. crosswise one by one, or else (as often occurs) holes have been drilled on the wheel with too wide
tolerances.
Small errors, up to 10 grams (0.4 oz) are to be considered normal in wheels locked by a cone; the
error is normally greater for wheels fastened with screws or studs.
If, after balancing, the wheel is found to be still out-of-balance when retted on the vehicle, this
could be due to the unbalance of the car brake drum or very often due to the holes for the screws on
the rim and drum sometimes drilled with too wide tolerances. In such case a readjustment could be
advisable using the balancing machine with the wheel mounted (For example, see our models L36,

L38/2).

11 - Self-diagnostics

When +

are pressed together, a test is enabled for the correct operation of the displays and LED’s of the

PC board after the end of which the wording

appears on the left display. At this point, correct operation of the

position sensor can be checked by looking at the positioning LED’s regarding the outside:

- When the wheel is moved slowly in the direction of rotation of the machine, the AUTO LED should start ashing
while the ALU-S LED should remain steady.

- When the wheel is moved slowly in the opposite direction, the AUTO LED should start ashing while the ALU1 LED
should remain steady.

- When switching from reset, the wording “ ” should appear on the right display..

- Press .

- A number appears on the RIGHT display, which is useful for calibrating the rim distance gauge (only for specialized
personnel).

- Press .

12 - Routine maintenance (see exploded drawings)

Before carrying out any operation, disconnect the machine from the mains.

12.1 - To replace the driving pulley

- Remove the head and the weight shelf being careful not to pull away the electrical cables.

- Unscrew the pulley mounting screw in order to replace the pulley.

- Check supply pressure of the spinner device (see PRESSURE ADJUSTMENT FOR SPIN AND BRAKING DEVICE).

- Excessive pressure will cause premature damage of the rubber.

12.2 - To replace the brake pad

Back-off the two screws fastening the worn brake pad to the motor mounting brake. Securely x the new brake pad
by tightening the screws.

12.3 - To replace the fuses

Remove the weight shelf in order to gain access to the power supply board on which two fuses are installed. If the
fuses need replacement, use ones of the same current rating. If the fault persists, contact the Technical Service De­partment.

12.4 - Maintenance of the special pneumatic circuit

It is important to periodically clean the compressed air lter and check that there be sufcient lubricating
oil The bowl should be lled 3/4; to top up, use mineral oil of medium viscosity (30 cSt at 20° C) (WAIR­SOL, LXOL grade). Normal oil ow rate is one drop every 10 operations.

N.B.: DRAIN FREQUENTLY ANY CONDENSATE BUILT UP IN THE FILTER BOWL VIA RELATIVE
