4. Indication and use of wheel balancer
4.1．DYN (Standard/Default) mode
4.1.1. Clean wheel, take off counterweights, check pressure of wheel.Choose the way of installation according to the
type of wheel.
Main shaft-wheel—Main shaft-suitable cone(big head towards inside)
suitable cone( small head towards inside)—quick handle nut —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.
4.1.2. Turn on machine

7
4.1.3. Input a b d value
Turn on 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
0.(The value measured in automatic mode appear on the display). Or press and and 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 and and to set manually.
● set “d” value：this value measured in automatic mode same time as “a” value setting, or press and
and to set manually.
Fig.1 Fig.2
4.1.4. Put down the guard and press to perform a measuring spin.
4.1.5. 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 may check the real unbalance value under threshold.
4.1.6.Anticlockwise moving wheel slowly, until the right LED lit up full, clip weight on 12 o’clock position (Fig.3)
Fig. 3
4.1.7．Anticlockwise moving wheel slowly, until the left LED lit up full, clip weight on 12 o’clock position (Fig.4)

Fig. 4
4.1.8．After finishing cliping the counterweights, put down the guard or press ，to perform balancing spin
again, if comes out 00 00，means balancing succeed. (Fig.5)
Fig. 5
4.2．ALU-1 mode (ALU-1,ALU2 same operation, only the position to add weights different)
4.2.1. Set “a” “d” “b” values
4.2.2. Press until ALU1 indicator lit up
4.2.3. Put down the guard and press to perform a measuring spin.
4.2.4. 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. Press may check the real unbalance value under threshold.
4.2.5. Anticlockwise moving wheel slowly, the displays with right LED’s lit up full indicate the correct angular position
where to mount the counterweights, (las=on,las=off) position outside, as Fig.6, add the counterweight.
Fig. 6
4.2.6. Anticlockwise moving wheel slowly, the displays with left LED’s lit up full indicate the correct angular position
where to mount the counterweights, (las=on,las=off) position inside, as Fig.7, add the counterweight.

Fig. 7
4.2.7. After finishing mounting the counterweights, put down the guard and press ，to perform balancing spin
again, if comes out 00 00，means balancing succeed. (Fig.8)
Fig. 8
4.3．ALU－S mode
This mode is used for special rim, ifALU1/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 and and
to change
Set “aE”: pull gauge out let the gauge head touch the position of FE for 4 seconds ，may press and and
to change
Set “dI”: read from rim, may press and and to change
Set “dE”: read from rim, may press and and to change
