1. Introduction

A balanced wheel is very important to the performance of your car. The result of an

unbalanced wheel can cause premature wear of your shock absorbers, steering and tyres. A

balanced wheel is also a major factor to road performance and the prevention of accidents

as unbalanced wheels affect road grip and steering.

This equipment is fitted with the new LSI (Large Scale Integrated circuit) which aids the

hardware system to calculate information at a high speed.

Read the manual carefully before operating the equipment to ensure safe operation.

Dismantling or replacing parts of the equipment should be avoided. Should any repairs be

necessary please contact the service department.

2. Mounting and Demounting the Wheel

The wheel must be clean, free of stones and objects, remove all the counterweights

from the rim. Check the tyre pressure. Check the rim for damage or deformation.

Mounting the wheel

Select the right sized cone for the rim. Mounting methods: A. positive positioning; B. negative positioning.

Positive (refer to figure 6-1):

Negative positioning (refer to figure 6-2):

Negative positioning is commonly used for steel rims, with possible deformation on the

outside of the wheel.

Note: do not slide the wheel across the threaded shaft.

3. The meaning of the icons

This row shows the different balancing modes, System and language adjustment.

Mode (M1): Press button 1. A yellow frame will appear which means the mode is activated.

The weight position can be seen marked red on all the icons, this mode is for clamp weights at a 12 O, clock

position.

Mode (M2): Press button 2. A yellow frame will appear which means the mode is activated.

This mode is for self adhesive weights which are applied to the inner and outer side at a 12 O’clock position

where the measuring gauge touches the rim.

Mode (M3): Press button 3 a yellow frame will appear which means the mode is activated.

This mode is for self adhesive weights, to be applied inside with the gauge and outside at 12 O, clock


This mode is for a self adhesive weight (with gauge) on the outer side and a clamp weight (at 12 O, clock) on

the inside.


This mode is for both self adhesive and clamp weights attached at 12 O, clock.


This mode is for self adhesive and clamp at 12 O, clock outer, and self adhesive weights to be applied inside

with the gauge.


This mode is for the static settings and optimal balancing. By pressing button 7 to enter the next step

Static balancing mode.

Press button 8 for the system settings. Type in the code 321

M9 is the language settings, with button 2 the language mode can be entered and adjusted with button 1- 6

Press START to confirm.

This is the information window (user instructions) it can be blended out by pressing R/0 .

This shows the wheel parameters necessary to balance wheels.

When the system is set to Gram, 100g is required for calibration.

When the system is set to ounce, 3,50oz is required for calibration.

System settings: For self calibration and gauge calibration etc.

Weight position:

1 = Scale for the inner and outer side

2 = When the wheel is turned by hand the scale fills and the indicator doubles in size (12 O, clock position).

3 = Scale for the distance setting A / A+ the scale must be full.

4 = This shows the required weight for both inner and outer

1 = Self

4. Using the keyboard

The buttons: 1 to 9 and “,” are for the values and selecting the program.etc.

Rim parameter:

A: Distance from machine to rim press button A, set the value with the numbers and then press START.

B: A+: Rim width: Press B set the value with the numbers and then press START.

D: Rim diameter: Press button D set the value with the numbers and then press START.

Other functions

START: To start the machine or to confirm a setting

STOP: To return to main menu

＜T: By pressing this button the display shows the exact gram value.

5. Parameter input methods

a) Program M1, M3, M5, M6: This is for the Parameters A / B / D

b) Program M2, M4: This if the Parameters A / A+/ D

c) Program Static or OPT: This is only for Parameter D

When working with the measuring gauge the value will automatically be saved in the machine for the balancing process

The values are saved by holding the gauge for approximately 2 seconds on the rim, a peep tone can be heard when the

machine has saved the reading.

Measuring the rim using the automatic gauge:

With the left gauge the inside rim values are measured. (Machine housing)

With the right gauge the outside rim values are measured (Wheel guard)

Mode (M1):

The left gauge measures the values A and D

The right gauge measures the value B

Mode (M2):


The right gauge measures the value A+

6. Description of the different modes

If a graphic bar appears over the weight display the weight must be applied with the gauge. If no bar is visible then the

weight must be applied at a 12 O, clock position.

Mode (M1):

1. Mount the wheel and give in the wheel dimensions A / B / D.

2. Close the wheel guard and press start (auto start can be turned on and off as required)

3. When the wheel stops lift the wheel guard. The required weight will be shown in the display.

4. Turn the wheel by hand until the red bar reaches the top of the left display. Apply the weight at 12 O, clock

5. Turn the wheel by hand until the red bar reaches the top of the right display. Apply the weight at 12 O, clock

6. Close the wheel guard and press start. When the wheel stops the reading should be 0g.

TWIN BUSCH GMBH


13

Mode (M2):

1. Mount the wheel and give in the dimensions A / A+/ D

2. Close the wheel guard and press start (auto start can be turned on and off as required)

3. When the wheel stops lift the wheel guard. The required weight will be shown in the display.

4. Turn the wheel by hand until the red bar reaches the top of the left display. Apply the weight at 12 O, clock. Pull out

the gauge until a peep tone can be heard use the gauge to apply the weight.

5. Turn the wheel by hand until the red bar reaches the top of the right display. Apply the weight at 12 O, clock. Pull out

the gauge until a peep tone can be heard use the gauge to apply the weight.

6. Close the wheel guard and press start. When the wheel stops the reading should be 0g.

Note!

When the bar appears above the weight icon the weight should be applied with the measuring guage. If no bar can be seen

then use the 12 O, clock method. This is the normal method for the modes M1 to M6.

Working with the static (M7) or dem OPT-Mode:

1. (To balance motorcycle wheels an adaptor is needed which is available as accessories.)

Press button 7 to enter the static-OPT mode, press 7 again to change between Static and OPT then start to confirm.

2. Mount the wheel and with the gauge measure the value D.

3. Close the guard and press start

4. After rotating the weight amount can be seen inner and outer.

5. Turn the wheel by hand until the red bar reaches the top of the right display. Apply the weight at 12 O, clock.

Tipp!

When the button „T“ is pressed the machine shows the exact required gram.

The machine has a factory setting of 5 g, this can be changed as necessary in the option mode.

Example: The machine shows a reading of 20g inner value and 30g outer, when T is pressed the machine shows 24g –

32g.

7. How to apply weights behind the spokes.

With this function the weights can be applied behind the spokes for a better optic from the front side of the rim.

The function can only be used with the M2 and M4 modes.

The following example is shown in the M2 mode.

Run Program M2 as decribed.

The required inner and outer weights are shown for as normal.

Now follow the steps:

1. Press button 7

2. Type in the amount of spokes then press START to confirm.

3. Turn the wheel and pull out the gauge, set the gauge in the middle of one of the spoke and press start.

4. 3 bars can now be seen on the monitor. The inner weight (first bar) can be applied as normal as in M2 with the

gauge.

5. The outer weight (second bar) is applied at 12 O, clock where the gauge touches the rim behind the spoke.

6. The second outer weight (third bar) can be applied at 12 O, clock where the gauge touches the rim behind the

second spoke.

7. The weights have been divided between the two spokes and are not visible from the front.

Second bar 15g behind

the spoke.

Third bar 25g behind the

spoke.
