1.Code Balancer
(Common steel and aluminium alloy steel rings)
2. Paste Balance Block
(aluminium alloy steel ring)
Note: the weight error of the balance block can directly affect the detection effect of
this machine.
Attention to the Use of Installation Box
1. Do not the tire balancer in extreme temperature and humidity. Avoid placing beside
heating equipment, faucets, air humidifiers or stoves.
2. Don't put the balance machine in front of the window where the sun can directly
enter. In unavoidable cases, curtains, baffles or shields should be used to shield the
balancer.
3. Avoid contact with large amounts of dust, ammonia, alcohol, diluents or spray
adhesives.
4. The balancer should be fixed on a smooth ground. Avoid placement next to air
compressors or objects that may vibrate.
5. Do not approach the machine when using.
6. The specification of the power outlet of the tire balancing machine is 110 v volts
( AC) with a rated output current of at least 10 A( amperes).
7. Tire balancing machine should use a separate power outlet, do not connect other
wires to the power outlet of the balancing machine, and note that the socket must be

reliably connected to the power cord of the balancing machine to avoid human
stampede.
8. Between the back and the wall of the balancer, there should be a distance of 50
CM to ensure good ventilation and heat dissipation.
9. Contact your maintenance service personnel before moving the balance machine.

Installation debugging method
1. Switch on and display HLP
2. Press F+FINE key to display the window is lit up
3. Press ALU key to enter the setting program. The current spindle tooth position is
displayed, and the spindle can be rotated forward and backward to check the
phototelex Sensory work.
4. Go to the spindle to 114, press Start, enter the spindle distance setting (the default
value is 195, which can be skipped if it is consistent with the real boundary) and
measure to the outer edge of the spindle flange with a ruler.
Enter the measured value with B + or B -.
Press A + to exit.
5. Go to the spindle -0-, press Start key, enter the spindle zero clearance program,
(this program can clear the spindle since
Press Start key to START the spindle, automatically reset and store and exit.
6. Press C to exit.
7. Put on the tire, input the tire data and then press F+C key to calibrate.
8. Press Start to display Add 100 after starting. Rotate the tire until the outside spot
lights are all on, outside the tire
After hanging 100 grams of lead blocks above the spindle, press START to display
100 ADD. Remove the outside 100 grams of lead blocks, turn the tire to the inside
point lights are all on. After hanging 100 grams of lead blocks above the inside spindle
of the tire, press START to display END CAL.
Balancing machine debugging is over.

Aging of balancing machine
1. Press F+FINE key to display the window is lit up
2. Press ALU key to enter the setting program. The current spindle tooth position is
displayed, and the spindle can be rotated forward and backward to check the
phototelex Sensory work.
3. Turn to the spindle to 100 and press Start to enter the aging procedure for 100
times.
Press START
Key after startup and count to start 100 times after the end of the buzzer prompt.
Balancing machine self check
1. Press F+FINE key to display the window is lit up
2. Press ALU key to enter the setting program. The current spindle tooth position is
displayed, and the spindle can be rotated forward and backward to check the work of
the photoelectric sensor.
Forward loops are added from 0 to 127, and reverse loops are reduced from 127 to 0.
You can also check the red light on the photoelectric plate, slowly turn the spindle, and
the red light will flicker alternately.
3. Press ALU button again to enter the pressure sensor detection.
The values of about 60 to 70 are displayed on both sides respectively. When the
spindle is pressed by hand, the values on both sides will change, which proves that
the two sensors work normally.

4. users resolve grid
instability
Fixed the same time .
5. if the fault is
troubleshooting ,
Re place the computer
board .
6. is adjusted according to
the method .
7. is adjusted according to
the method .
8. will re - enter the three
dis\In-1\SFA parameters by
the parameter value
calibrated in the chassis ,
then adjust and check if the
machine is normal .

Method of adjusting three parameter values:
In normal use, if there is too much or uneven lead block phenomenon, first of all, if the
above phenomenon occurs under self-calibration, then adjust the parameters of the
triplet.
1. adjustment angle SFA value: after self-calibration, it is found that the position of
100g lead block is not directly below the spindle or the value is not correct, Can use
this function to see 100 grams of lead block imitation off the spindle about how many
degrees. Remove this lead and hold down the R and START start keys, About nine
seconds later, The monitor stops flashing, Press the A value corresponding to the (-)
key after pressing the corresponding (+) key display when all the (F) key at this time
the left display window appears dis symbol, On the right, Without thinking about it,
Press the (+) key corresponding to the A value again (where the key represents the
entry) to display the value on In—1 right, Press the A (+) to get into the SFA window,
The right window shows the value of the position of the 100 g lead block. When it is
necessary to change its value. You can press the (+) of the L key or (-) to adjust the
deviation of 100 grams from the spindle at self-calibration, Keep pressing A
corresponding (+) key to exit, Back to school, Sometimes it is necessary to adjust the
SFA value to 100 g lead block directly below the spindle.
2.adjust the dis value: this is used to solve the problem of inner inaccuracy, flatten the
rim, put 100g lead block on the outside, see the value on the display window should
be in the range of 104-96, take 100g lead block on the inside, if the display value is
normal in the range 104-96, If the search method is the same as the SFA value, adjust
the (+)(-) key to the L key.
3. adjust In-1 value: this can solve the problem of internal and external score, If you
put 100 grams of lead on the inside, If the inside shows 990, If the number is 10, you
need to adjust this, After self-calibration, enter I n-1, state to adjust memory value In-1
value (the (+)(-) key corresponds to the L key) if the display value exceeds 110 g,
Need to reduce this, After the completion of the retreat to the initial state of
self-calibration.
(1).CB series balancer operation panel to UP represent (+) key, DOWN represent (-)
key.
(2).CB series balancer operation panel represents (R) key SEL (F) key.
3.adjusting the values of the three parameters, be sure to unload 100 grams of lead,
each parameter must be adjusted to make the computer board remember the data
you re-enter.
