Install wheel

• Clean wheel, take off counterweights, check pressure of wheel.
• Choose the way of installation according to the type of wheel.
• Main shaft-wheel— suitable cone( small head towards inside)—quick handle nut
• Main shaft-suitable cone(big head towards inside) —wheel—quick handle nut

Indication and use of wheel balancer

DYN (Standard/Default) mode
Clean wheel, take off the counterweights, check the pressure of the wheel.Choose the way of installation according to the type of wheel.

• Main shaft-wheel— suitable cone( small head towards inside)—quick handle nut
• Main shaft-suitable cone(big head towards inside) —wheel—quick handle nut

Attention：May add a wheel, and hold the wheel to help install the thread hub. When installing or taking off wheel, do not let wheel move on the shaft, to avoid scratching shaft.

Turn on machine
Input a b d value
Turn on the machine, choose right way to install wheel according to the type of wheel. Set “a” “b” “d” values:

• set “a” value ： move the gauge to measuring position as illustrated as Fig.1, hold the gauge still in position for approx. 4 seconds, successful memorization is given, then return the gauge to position
• (The value measured in automatic mode appear on the display). Or press a+ and a- to set manually.
• set “b” value：set nominal diameter “b” marked on the wheel or use the width gauge to measure the value of ”b” as Fig.2, then press  b+ and b- .
• set “d” value：this value measured in automatic mode same time as “a” value setting, or d+ press d- and to set manually.

1. Put down the guard and press start to perform a measuring spin.
2. In a few seconds the wheel is brought to operating speed and begin measuring unbalance, the unbalance values remain on instruments 1 and 3 when the wheel stopped. Press fine may check the real unbalance value under threshold.
3. Anticlockwise moving wheel slowly, until the right LED lit up full, clip weight on 12 o’clock position (Fig.3)
4. Anticlockwise moving wheel slowly, until the left LED lit up full, clip weight on 12 o’clock position (Fig.4)
5. After finishing cliping the counterweights, put down the guard or press start ，to perform balancing spin again, if comes out 00 00，means balancing succeed. (Fig.5)

ALU-1 mode (ALU-1, ALU2 same operation, only the position to add weights different)

1. Set “a” “d” “b” values
2. Press ALU until ALU1 indicator lit up
3. Put down the guard and press START to perform a measuring spin.
4. In a few seconds the wheel is brought to operating speed and begin measuring unbalance, the unbalance values remain on instruments 1 and 3 when the wheel stopped. The press FINE may check the real unbalance value under threshold.
5. Anticlockwise moving wheel slowly, the displays with right LED’s lit up full indicate the correct angular position where to mount the counterweights, 12 o’clock position (9H=Off) or 9 o’clock (9H=On) position outside, as Fig.6, add the counterweight.
6. Anticlockwise moving wheel slowly, the displays with left LED’s lit up full indicate the correct angular position where to mount the counterweights, 12 o’clock position (9H=Off) or 9 o’clock (9H=On) position inside, as Fig.7, add the counterweight.
7. After finishing mounting the counterweights, put down the guard and press START ，to perform balancing spin again, if comes out 00 00，means balancing succeed. (Fig.8)

ALU－S mode
This mode is used for special rim, if ALU1/ALU2 can not be used, you should choose ALUS mode. Input aI, aE, d value

• Set “aI”: pull gauge out let the gauge head touch the position of FI for 4 seconds, may press a+ and a- to change
• Set “aE”: pull gauge out let the gauge head touch the position of FE for 4 seconds ，may press b+ and b- . to change
• Set “d”: read from rim, press d+ and d- to input

Put down the guard and press start to perform a measuring spin.
12 o’clock position to add weight
Set SLC as OFF according to 8.1 Anticlockwise moving wheel slowly, until the right LED lit up full, add weight on 12 o’clock position (Fig.10)

Anticlockwise moving wheel slowly, until the left LED lit up full, add weight on 12 o’clock position (Fig.11)

After finishing mounting the counterweights, put down the guard and press start ，to perform balancing spin again, if comes out 00 00，means balancing succeed. (Fig.12)

• Use gauge head to add weight Set SLC as ON according to 8.1
• Anticlockwise moving wheel slowly, until the right LED lit up full (Fig.14)
• Take off proper counterweight to be hold by the gauge head as Fig. 16.
• Pull out gauge until there is a square comes in the middle window (Fig. 17)
• Release the counterweight and let it stick on rim (Fig. 18)
• Anticlockwise moving wheel slowly, until the left LED lit up full (Fig.19)
• Take off proper counterweight to be hold by the gauge head as Fig. 16
• Pull out gauge until there is a square comes in the middle window (Fig. 20)
• Release the counterweight and let it stick on rim (Fig. 21)
• Then turn down safe guard and press start to start spin, comes Fig. 22 means the wheel is balanced.

ALUS split function

Note: Only ALU-S mode can use this function. And Operator must be experienced.

Self-calibration of wheel balancer

Self-calibration of wheel balancer
5.2.Turn on balancer, install a medium size wheel (14″-18″)which can use clip- on weight, set “a b d” value, then Do the self-calibration whenever you think the balancer is not accurate. The 100g weight must be accurate.

Rim distance gauge calibration

Rim diameter gauge calibration

• Set “d” by press d+ and d- , （for example if it is 14 inch, make it 14）

Errors

Various abnormal conditions can arise during machined operation by the microprocessor, if comes the errors, must stop operation, find the reason and the solution according, if the error persists, consult the supplier.

Self- diagnoses

Setting machine

Machine setting

• Press stop and hold, then press C goes to set machine, press b+ and b- to change，press a+ to next

Safe guard setting

OPT function

Note: When unbalance value is too much, choose OPT, and the operator must be experienced.

Install wheel, input a b d value
