Operating Instructions
1. Self-check
When switched on, the system begins self-check and then enters standard dynamic mode measurement (Refer to Fig3).
Fig3
2. Installing Wheel
Choose the optimal cone for the center hole and mount it on the balancer. (Refer to Fig4 and 5)
The method shown in figure 5 is preferable because it approximates to installing wheel on a real car.
Fig4 Fig5
3. Wheel Parameters Input
Unlike ALU S which needs 4 parameters, other modes need 3 parameters.
Parameter values are shown in Fig6 (dynamic and static modes, ALU 1-3 mode, motorcycle mode) and Fig7 (ALU S mode).
Users can finish the parameters input manually (Refer toFig8).
Note: Motorcycle tires automatic input parameters also need to install a dedicated extension rod. (Refer to Fig 18)

Press to choose parameter, and press to modify parameter value. After inputting the parameter press to
save and enter next parameter input state. In the state of D value input, press to convert mm and inch.
4. Choose balance modes
The default mode of this equipment is standard dynamic mode. Choose other mode by pressing keys DYN/STA、ALU、MOT
(See Fig 9).
OPT mode can be operated by pressing the key OPT under dynamic and static modes.
Press STOP can stop measurement during measurement

5. Standard Dynamic Mode
This function is to test the amount of unbalance on the inside and outside of the rim while a wheel is rotating. Placing
counterweight on the tested position of both sides of the rim according to the displayed unbalance value can eliminate
unbalance.
First, choose standard dynamic mode, then install the Wheel and input parameters, after that follow the process of standard
dynamic operation in Fig10.
Or close the guard
Stop rotating measurement by opening the guard or
pressing STOP key in emergency
After correct input of
wheel parameters
Open the
guard
Measurement finished and the result is
displayed
Rotate the wheel,clamp a counterweight
of the displayed value(eg:70g)on the
outside correction position
Keep rotating,clamp a counterweight of
the displayed value (eg:40g) on the
inside correction position
Balancing finished
Fig10
The three values from left to right shown in Fig10 are unbalance value of the inside rim, static value and unbalance value of
the outside rim respectively. When the left and right unbalance values are 0 and the middle static value is more than 5g, then
by pressing FINE key the unbalance values less than 5g after standard dynamic balance will be displayed on the left and right
side of the screen. Now it is recommended to do static balance to achieve complete balance.
6. Static Mode
After dynamic mode measurement, you can select static mode directly. The balancer will automatically calculate the result of
static mode.

Or first, choose static mode, then install the Wheel and input parameters, after that follow the process below.
Fig11
7. ALU 1----ALU 3 Modes
ALU1-3 mode refers to 3 counterweight sticking modes reduced according to the shapes and sizes of most rims. (Refer to
Fig12)
A special purpose gauge can be used to assist in sticking counterweights in Fig 13.
The measurement processes of ALU1-3 are the same as that of standard dynamic mode.

8. ALU S Mode
This mode can input the precise size of the correction plane with the aid of mechanical sensor arm. It compensates for
ALU1-3 and is more accurate than the traditional ALU mode. It is easier and faster to use as well.
Fig14
1) ALU S Correction Plane choosing
ALUS has to choose two proper correction planes on both sides of rim. Clean the position to be used to get ready for being
stuck.
2) ALU S Mode Operation
Mount the wheel and collect parameters. After collecting, close the guard, press START to measure. The process is the same
as that of standard dynamic mode.
See Fig15 for the outside sticking process. After measurement, rotate the wheel to the outside correction plane position
according to the figure. The position is calculated automatically by the parameters collected by mechanical sensor arm, so the
real correction position is not necessarily at 12 o’clock, in this case, locate the position with the mechanical sensor arm
The inside sticking process is shown in Fig16.

Note: The KWB-511 mechanical sensor arm can only locate the 12 o’clock position, it will return to the measurement
interface if at any other position. So it is better to locate it at 12 o’clock and do the following operation.
9. OPT Function
OPT function is used to determine the best mating of tire and rim. When doing dynamic and static modes, if the static
mode value is greater than OPT value (implied 30g), then it’s better to start optimization.
When optimization is asked, press key to operate according to the following table. When optimization is not needed,
display “OFFOPT” and exit OPT operation.

Press OPT key to start
Step1
Rotate the gas nozzle to 12 o’clock.
Press ENTER key to memorize the point .Mark with a chalk a
reference mark on the tire
Step2
Remove the wheel from the balancer using a tire changer. Align
the nozzle and the mark by rotating the tire on the rim by 180
degrees.
Step3
Replace the wheel on the balancer and rotate the gas nozzle to 12
o’clock again. Press “ENTER” key to memorize
Step4
Press START key to start OPT measurement.
After measurement, mark with chalk again on the tire the marked
point indicated on the screen.
Using the changer to assemble until the new mark and the gas
nozzle coincide. Now the value displayed is the rest value after
optimization .On this point add 10g counterweight.
Press ENTER to end optimization
10. Motorcycle Mode
Motorcycle mode is the same as standard dynamic mode except that it needs special motorcycle fixtures and extending arms.

Error Information and Treatment
It provides the error diagnostics and prompting information of this equipment. Users can judge and deal with problems
according to the prompting information and the solutions given in the following form.
prompting information meaning of the information solutions
CCC CCC The result of measurement is beyond the
range.
OFF OFF System gives the prompt when the STOP key
is interrupted accidentally
Err 01 When the guard is set enabled, press START
key without closing it or open the guard
artificially while the wheel is in rotating
measurement. In either of these two cases,
the balancer gives the prompt
Close the guard, or turn off the
guard function option in setting
items. However, because the laws
and regulations of safety protection
in different countries are not
completely the same, we suggest
not turning off the guard function
option.
Err 02 Prompt is given and measurement is stopped
when rotating speed is too low to meet the
basic measurement needs,
Problems of the electrical motor
shaft or the transmission belts.
Check and adjust.
Too light load also results in this
phenomenon, so please adjust the
load weight.
Err 03 The measurement rotation is in wrong
direction. This usually will appear in the
three-phase motor control balancer due to
sequence errors
Adjust the sequence of the
three-phase power.
ERR 10 Gauge error Turn off the machine, return the
gauge to position 0, and then restart
it. If the error still exists, calibrate
the gauge following “Calibration
programs”
ERR CAL The machine is not calibrated. Users calibrate the machine
following “Setting programs”
ERS CAL Factory maintenance error. Contact the manufacturer.
