Machine assembly

Unpack

Unpack the carton, check if missing any spare part

Install

The equipment should be installed on the stable ground, not wooden pallet, otherwise not accurate.
Keep the back panel 0.6M away from the wall for good ventilation. Enough room should bele ft on both sides for convenient operation.

Fix balancer to floor with screws on the bottom.

Install adaptor

The wheel balancer is supplied complete with cone type adaptor for fastening wheel with central bore. (seebelow picture)
Install adaptor

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.

Indication and use of wheel balancer

DYN (Standard/Default) mode

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.

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 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 gauges tillin position for approx. 4 seconds, successful memorization is given, then return the gauge to position 60.(The value measured in automatic mode appear on the display). Or press and to setman ually.
set “b” value: set nominal diameter “b” marked on the wheel or use the width gauge tomea sure the value of ”b” as Fig.2, then press and.
set “d” value: this value measured in automatic mode same time as “a” value setting, or press and to set manually.

Anticlockwise moving wheel slowly, until the left LED lit up full, clip weight on 12 o’clock position (Fig.4)

After finishing cliping the counterweights, put down the guard or press to perform balancings pinagain, 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)

Set “a” “d” “b” values Press until ALU1 indicator lit up 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 valueunderthres hold. 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, 12 o’clock position (9H=Off) or 9 o’clock (9H=On) position outside, asFig.6, addthe counterweight.

Anticlockwise moving wheel slowly, the displays with left LED’s lit up full indicate the correct angular positionwhere to mount the counterweights, 12 o’clock position (9H=Off) or 9 o’clock (9H=On) position inside, as Fig.7, addthe counterweight.

After finishing mounting the counterweights, put down the guard and press to perform balan cings pinagain, 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 and to change
Set “aE”: pull gauge out let the gauge head touch the position of FE for 4 seconds ，may press and.to change
Set “d”: read from rim, press and to input

Put down the guard and press to perform a measuring spin. 4.3.1. 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 to perform balan cings pinagain ,if

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 to start spin, comes Fig. 22 means the wheel is balanced.

Self-calibration of wheel balancer

Self-calibration of wheel balancer

Do the self-calibration whenever you think the balancer is not accurate. The 100g weight must be accurate.

Rim diameter gauge calibration

Set “d” by press Icon and Icon ,(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 stopope ration, find the reason and the solution according, if the error persists, consult the supplier
