Wheel balancer MM-WB1024
User’s manual
007935017275 007935017280
1. Introduction
An imbalanced wheel will make the wheel jump and steering wheel wobble while driving. It
can baffle the driver to drive, aggrandize the cleft of combine area of steering system, damage the
vibration damper and steering parts, and increase the probability of the traffic accidents. A
balanced wheel will avoid all these problems.
This equipment adopts the new LSI (Large Scale Integrated circuit) to constitute the hardware
system that acquires processes and calculates information at a high speed.
Read the manual carefully before operating the equipment to ensure normal and safe
operation. Dismantling or replacing the parts of equipment should be avoided. When it needs
repairing, please contact with technique service department. Before balancing, ensure the wheel
fixed on the flange tightly. Operator should wear closefitting smock to prevent from hanging up.
Non-operator does not start the equipment. No use while beyond the stated function range of
manual.

3 The Constitution of Dynamic Balancer
Two major components of the dynamic balancer are: machine and electricity:
3.1 Machine
The part of machine consists of support, swing support and main shaft; they are
together fixed on the frame.
3.2 Electricity system
1. The microcomputer system is made up of the LSI such as new high speed MCU CPU system and
keyboard.
2. Automatic measure scale.
3. Testing speed and positioning system consists of gear and opto-electronic coupler.
4. Two-phase asynchronous motor supplies and control circuit.
5. Horizontal and vertical pressure sensor.
4 Installation of Dynamic Balancer
4.1 Opening and Checking
Open the package and check whether there are damaged parts. If there are some problems,
please do not use the equipment and contact with the supplier. Standard accessories with
equipment are shown as follow:
Screw stud of drive shaft 1
Balancing pliers 1
Allen wrench 1
Measure caliper 1
. Hood protection.

4.2 Installing machine
4.2.1 The balancer must be installed on the solid cement or similar ground, unsolidified
ground can bring measuring errors.
4.2.2 There should be 50cm around the balancer in order to operate conveniently.
4.2.3 Nail anchor bolts on the base’s mounting hole of balancer to fix the balancer.
4.3 Installing hood
Install the frame of hood on the equipment (optional): plug the pipe of protection hood into
the hood shift (behind the cabinet), then fix with M10×65 screws.
4.4 Installing screw stud of drive shaft
Install screw stud of drive shaft on the main shaft with M10 × 150 socket bolt, then screw
down the bolt. (Refer to figure 4-1)
Figure 4-1
(Notice: a wheel can be installed on the main shaft before screwing down, then hold the
wheel by hands in order to prevent the main shaft revolving together with the bolt.)

N.B. Only use the fingers to press push buttons. Never use the counterweight pincers or other
pointed objects.
6 Installation and Demounting of the Wheel
6.1 Checking the wheel
The wheel must be clean, none sand or dust on it, and remove all the primal counterweights
of the wheel. Check the tyre pressure whether up to the rated value. Check positioning plane of
rim and mounting holes whether deformed.
6.2 Installing the wheel
6.2.1 Select the optimal cone for the center hole when there is center hole on the rim.
6.2.2 Two ways of installing the wheel: A. positive positioning; B. negative positioning.
6.2.2.1 Positive positioning (refer to figure 6-1):
Positive positioning is commonly used. It operates easily, and it is applicable for
various rims of common steel structure and thin duralumin structure.
6.2.2.2 Negative positioning (refer to figure 6-2):
Negative positioning is used to ensure the inner hole of steel rim and main shaft is
positioning accurately when the outside of wheel deforming. Apply for all the steel rims,
thick steel rims especially.
Figure 6-1 Figure 6-2
6.2.3 Install wheel and cone on main shaft. Ensure the cone can clamp the wheel before
screwing handle. Wheel can rotate after screwing down.
6.3 Demounting the Wheel
6.3.1 Demount the handle and cone.
6.3.2 Put the wheel up, and then take it down from main shaft.
Note: do not slip wheel on main shaft to prevent main shaft from scuffing while installation and
demounting the Wheel
7 The input methods of date of rim
7.1 The power-on state of the machine
After the power-on of the machine, it starts initialization automatically. The initialization will
be finished after two seconds. The machine enter natural dynamic
(clamp counterweights on the correction plane of the both edged sides of rim) mode
automatically
Figure 7-1
7.2 Date input method for normally dynamic balance mode
7.2.1 After the power-on of the machine, it enter the normal balance mode 7.2.2 Input
date of rim:
Figure 7-2
Rotate the measure scale, pull the scale head to inside concave on the edge of the rim, etc
figure 7-2, first LED all off, then display ect figure 7-3,waiting put back scale.
Figure 7-3
When scale back to zero position, LED display value is date of rim.
7.2.3 When measure values with fact value of rim differ, you need selfcalibration of scales
then measure again or manual input date of rim.
7.2.4 Input date of rim width
7.2.4.1 Put width scale head on rim outside edge, ect figure 7-4. First LED all off, then
display ect figure 7-5, waiting put back scale.
Figure 7-5
When width scale back to zero position, LED will be display ect figure 7-1.
7.2.4.2 When measure values with fact value of rim differ, you need selfcalibration of
width scale then measure again or manual input date of rim.
7.3 Date input method for ALU-1 to ALU-5
When you use function keys form ALU-1 to ALU-5, input data accord 7.2, and then
press ALU key directly to choose relevant ALU function. No need input tyre data again.
7.4 Date input method for Static balance mode
After turn on the machine, press the F4 button to show 7-6 diagram. The right figure
show the tyre diameter.
