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.

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.)

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.

Figure7-6
Move the calliper, against the calliper head to the middle of rim. As the figure 7-7.
Now the display screens whole closed. When finish measure, the machine makes a warning
voice as “Bi”and show the figure 7-3.
Figure7-7
Put the calliper back. And then the right digital tube shows the data of rim diameter.
7.5 Date input method for ALU-S balance mode
ALU-S mode is a special mode which can include two modes as below (Fig.
7-8)
Left figure is ALU-S1，right figure is ALU-S2
ALU ALU
S S
Figure7-8
7.5.1 Date input method for ALU-S1 balance mode
As the figure 7-9,move the calliper to the inside of rim (FI)，measure the inside
range (aI) and diameter (dI). When the machine displays figure 7-3，go on move calliper
to outside of rim(FE) to measure the outside ranger of rim (aE) and diameter (dE). After
that the machine displays Fig.7-11 enters into ALU-S1 mode.

Figure7-9
7.5.2 Date input method for ALU-S2 balance mode
As the figure 7-10,move the calliper to the inside of rim (FI)，measure the inside
range (aI) and diameter (dI). When the machine displays figure 7-3，go on move calliper
to outside of rim(FE) to measure the outside ranger of rim (aE) and diameter (dE). After
that the machine displays Fig.7-11 enters into ALU-S2 mode.
Figure7-11
After put back the calliper the machine shows data aI、aE and dI. The screen show
figure 7-6. Press a+、a- can adjust data aI(aI indicator light on). Press b+、b- can adjust
data aE(aE indicator on). Press d+、d- can adjust data dI(dI indicator light on). Press FINE
button digital tube shows dE data (dE indicator light on). Press button FINE in the same time
press d+、d- to adjust dE data.
8 Calibration of measure scale
The measure scale was labeled before ex-factory, but the labeled value may vary because of
transportation. Therefore, users can label it themselves before using the balancer.
After the power-on, the initialization is finished. Thus, users can label the measure scale

9 The Self-calibrating of Balancer
The self-calibrating of balancer was finished before ex-factory, but the system parameter
may vary because of long-distance transportation or long-term use, which may cause error.
Therefore, users can make self-calibrating after a period of time.
9.1 After the power-on of the machine, the initialization is finished ect figure 7-1，install a can clip
counterweight and comparatively balance middle size tyre, follow step 7 input date of rim;
9.2 Press D key and C key, ect figure 9-1, (close protect hood), press START key, going to next
step(press STOP key or C key to exit);
Figure 9-1
9.3 After axis stop, ect figure 9-2,(open protect hood)clip a 100 gram counterweight on anywhere
of outside of rim, (close protect hood)press START key, going to next step(press STOP key or
C key to exit);

Figure 9-2 9.4 After axis stop, ect figure 9-3,
calibration end. Demount tyre, now balancer ready to work.
Figure 9-3
NB：when you doing self-calibration, input date of rim must be correct,100 gram
counterweight must be correct, otherwise self-calibration result will be wrong, wrong self-
calibration will be make balancer measure precision decline.
