Operation

Switch on the main switch

Display window shows equipment code, afterward“A-8.0”, which approves that the machine runs normally.

Wheel mounting

test preparation：Check and clean all dust and dirt, and metal or stone clipped between on tread。Check whether the tire pressure conform to specified value. Check there is any deformation on rim locating surface and mounting hole, check if any foreign body inside tire, remove all counterweight.
there are 3 kinds of methods about wheel installation: A. front cone mounting B. back cone mounting C. special made flange mounting. You can select the methods according to different conditions.

A：Front cone mounting

The front cone mounting is the normal method. It is featured with simple and quick operation. It is mainly suitable to common steel rim and aluminum alloy rim with small deformation。

Main shaft―wheel (direction of the rim installation surface is inside) ―suitable cone (small side inside) ―wheel―quick nut

B: back cone mounting

When the deformation of the outside of the wheel is heavy, adopt this method to grantee the accurate positioning of the steel rim inner hole and main shaft. It is suitable to all steel rim, especially the thick ALU。

Main shaft――tower spring――suitable cone (big side inside) ――wheel――quick nut

C: special made flange mounting

Wheel mounting

Fixed flange disk on the main shaft――wheel――big cone――quick nut

Note : The choice on the cone should be adapted to the rim center hole and pay attention to its direction. Or it will cause the inaccurate measurement.

Wheel parameter input

First input distance “A”

Pull the scale to the inner position on the rim, read this value “A”
Press “+”to increase the value
Press “-”to decrease the value
Until you get correct value.
Input width “B”

Use the Br. measurement caliper to measure the Br. of the rim “L”
Press “+”to increase the value
Press “-”to decrease the value
Until you get your measured value L
Input diameter “D”

Find diameter “D” marked on tire
Press “+”to increase the value
Press “-”to decrease the value
Until you get correct value.

Select balance mode

Choose different balancing modes according to the position and mode of adding balance lead. First, press the “F” key, select the window to light up, and continuously press the “ALU” key to display the following different balancing modes in the “balance mode display window” (such as the control panel diagram).The default balance mode is dynamic balance,t he display window does not show.

Select balance mode

Dynamic balancing – the balancing lead is inserted on both sides of the rim to adjust the steel rim and the aluminum rim balance.

Static balancing – use static balancing when the sides of the motorcycle or rim cannot be inserted in the balance lead.

ALU1—- The light alloy rim adopts this method to balance. Attaching balance lead on both sides of rim.

ALU2— The alloy rim adopts this method to balance. Internal adhesion of the balance lead.

ALU3—- The inner ring clamps the balance lead, and the outer side adheres to the balance lead (the position of the outer side balance lead is like ALU2).

Balance wheel

press START key,8 seconds later, the automatic brake display is shown in the figure:

40 is the inner side error data of the tire 10 is the outside error data of the tire.
Turn the tire slowly. When the inside light is on, insert 40g lead directly above the vertical shaft on the inside of the rim. Shown as in figure:
Turn the tire slowly. When the outside light is on, insert 10g lead directly above the vertical shaft on the outside of the rim. As shown in figure:
Press START key to rotate the tire. After automatic braking, the display window displays 0-0. The balance is finished and then unloaded the tire.If you do not disply 0-0, repeat the above steps until shown as 0-0.

NOTE

When the power equipment starts, push the tire by hand to assist the operation and extend the motor life.
Check whether the input size is wrong, press C key to automatically detect A, B, D data.
if the balancing mode is consistent with rim structure. (see 4.4 balance selection)
Check if the lock nut is tightened.
When the balance is over and the tire is unloaded, take care not to hit the shaft.
When using the balanced lead with clamp, use the balance hammer to gently nail it on the rim edge. It is better not to shake it off. When the balance is over, put the tire on the ground and knock it tight, do not hit it hard on the shaft to avoid damaging the sensor. The position of adhesive balance lead must be free of oil and dry

OPT Unbalance optimization

It is recommended to perform this program when the unbalance data exceeds 30g to reduce the number of added balance lead.
The following programs should be operated with great care for optimum results.
Press OPT key, shown as: [OPT][ ] (press＜STOP＞key to stop the program) press＜START＞key, the tire will rotate, when the rotation is over.
Display [︱→︱][ 180 ] the display screen shows “180” that means the rims and tires should rotate 180 degrees each other and be reloaded back into the balancer.
Shown as：[45] [80 ]right show screen：Displays percentage of unbalance data that can be reduced by the current wheel position (display with %).
Left show screen：the unbalance data. Shows the unbalance data that can be reduced by rotating the tire around the rim.
Shown as：[45] [80 ] Rotate the tire so that the outside unbalance light is all on, marking at the top of the tire (at 12 o ‘clock position)
[45] [80 ] Rotate the tire again so that the inside unbalance light is all on, marking at the top of the rim (at 12 o ‘clock position).Demount the tire, Use the tyre changer to overlap the tire and rim marks.
In the above example, 80 percent of 45g static unbalance data can be reduced, and the remaining unbalance data is 9g.

Maintenance and repair of balancer

self-calibration

Self-calibration is completed before be released. When the machine has been used for many years or the parts are replaced or the balance error is too large, it can be re-calibration. Choose a tire (13 inches or 14 inches of steel ring) and mount on the main shaft then enter the correct values of A, L, D for this tire.
Note : select standard tires for self-calibration and enter dimensions correctly, otherwise it will lead to inaccurate measurements later. Used the standard tire for self-calibration

Maintenance and repair of balancer

press F key，After half a second, hold down the C key at the same time, and the display screen shows “CAL” – “CAL” indicator light is all on and flashing, then release hands when the indicator light is off.
press START key，The wheel turns to brake automatically after a few seconds, and the display panel shows “ADD” – “100”, add 100g lead to the outer edge of the wheel. If no 100g lead, it can be replaced by two pieces of lead with a sum of 100 grams.
Press START key，the wheel is rotation and then brake automatically，display panel shows as “END”-“CAL” that means the self-calibration is over.
Press START key，Stop and display data after 8 seconds. This step is to visually demonstrate whether theself-correction is successful and accurate.
Two factors to determine whether self-calibration is accurate
The display data is accurate (” 00 “-” 100 “allows for± 4g error).
Display accurate phase ( the outside indicator light is all on, 100g lead is at underface in the shaft, allowing for ±4g error). If the unbalanced tire is used as self-calibration, the lack should be found before self-calibration, and 100g lead should be placed at the location of the lack , so that the phase is accurate. Examples are as follows.
The unbalanced tire should find the lack points on the outside side before the self-calibration, as shown in the figure: turn to the outside indicator light is all on and make a mark on the front of the tire.
When self-calibration is carried out according to 5.1 steps “1” to “2”, 100g lead are added on the marked points, and finally pls see the self-calibration results .As shown in figure:

100g lead is added on underface, the indicator light will be on
