1.4.Operating principle
The CPU can only run the balancing operation when it receives the normal information from
each unit. In the balance process, the CPU comprehensively analyzes the unevenness detected
by the piezoelectric sensor and the Angle signal of the counting sensor, calculates the unbalance
value, which is displayed by the LED, realizes man-machine dialogue through the keyboard, and
achieves the tire balance.

3.7.Precautions in the process of use
Attention:
·When power starts, push the wheel by hands to assist starting which will extend motor’s
life.Due to balance angle error, please find out by yourself when this machine rotates wheel to
find balance point, pay attention which direction is much more accurate when wheel turns
inward or outward.
·As the balance is over, unload the tire, pay attention to handling with care , don’t strike the
main shaft.
·While assisting braking , by the time when the display board has data to show , then can step
on the pedal brake at the lower right corner of the machine , otherwise diminish the life-span of
the machine.
3.8.Balancing experiences:
1.As indicated data is less than 50g, lead lump can be struck at the same time on both sides
2.When number is greater than 50g , producer proposes to balance one side after another,
namely one side which balance number is greater is balanced to reach “00” and then another
side is balanced to reach " 00 ".
3.When there is still a small remaining part of lead lump after striking lead lump, it is because
there is a error of lead lump position,it can be solved through moving lead lump to direction
where there is space.
4.After “00”-“00” occur, 5,6,7g will occur also by accident, it is thought to normal
phenomenon.Precision of this machine is 5g namely it is zero below 4g. Allowed change scope
of this machine is 3g, 7g error will indicate by accident, it will not affect balancing effect of this
machine.
5.When appearing incorrectly or repeatedly strike but not reach 00, you can self correct the
machine (please see the next page for re-storation of standard process)
Comments: This experience is only for reference. Hope user can grasp machine
performance skillfully for better use.

4.Self -calibration（Car and truck tires need to be corrected separately）
Self correction has been finished in the factory. If you use for many years and change part or
doubt balance to be a big error, you can self correct it again.( Choose one medium-sized tire to
install on main shaft , uneventy of steel rim on both sides of wheel is relatively slight)
Warning:When going self calibration, Make sure that the wheel is required to be
plentiful air, Remove dirt or impurities from the tires, The balancer must be stable
1.Input correct number of this tire A, b ,d.
Attention: Incorrect input of size will lead to that machine can’t correctly determine caliber
so following measurement will have errors.
2.at the same time press and keys，A few seconds later，display window show CAL
CAL
3.press key show Add 0，press START key, after the machine stops running show Add
100, push the wheel, just above the outside position,(When the leaded position indicator lights
are all on), add 100g standard lead lump
4.then press START key, after the machine stops running show100 Add ,Remove the 100g
rectified lead block from the outside,directly above the inner side position（When the leaded

Two key elements to judge if self correction is accurate
1. Accurate number indication
2. Show that phase is right (namely outside indicator lamps are all on and 100g lead lump is
rightly under shaft. )
Problems that occur after self correction:
1.Number indicated is ok, but phase is inaccurate, deviation is very great.
Trouble: don’t reduce after finishing striking the lead lump, usually the store device is
damaged . Change it.
2. Showing ERR (this machine screen shows Err. -8-)
A .Problems with computer board.
B .The circuit of sensor is broken.
3.Number indicated has a big deviation, namely within 10g. (not affect using )
A. Generally use lead lump of 100g inaccurately.
B. The edge outside wheel rim is irregular, can take down the lead lump and strike lead lump
again on the opposite side and make comparation through drawing 2 times average.
4.Self correction cann’t be done because of different practices, fingers can
slightly give a push. Time difference between two fingers is half a second.
5. Number indicated deviates a lot , changed number is still very big , generally because the
board damage of the computer or the sensor is problematic.
