2.1. Unpack

Unpack the carton, check if missing any spare parts.

2.2. 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 be left
on both sides for convenient operation.

2.3. Fix balancer to floor with screws on the bottom.

2.4. Install adaptor

The wheel balancer is supplied complete with cone type adaptor
for fastening wheel with central bore.

2.5. 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–
• 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.

Product Usage Instructions

1. Turn on the machine.
2. Input a, b, d value.
3. Start spin, after spin stop.
4. To add weights, clip on weights on both sides of rim edge or
   add adhesive weights on the rim shoulder both sides or clip on
   weight on inside rim edge, add adhesive weight on outside rim
   shoulder or add adhesive weight on inside rim shoulder, clip on
   weight on outside rim edge or add adhesive weights on the two
   positions gauge head touch.

Note: The equipment can only be operated by
qualified personnel with special training. Modification to any
components or parts, or use the machine for other purpose without

AttentionMay 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

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

5

0.(The value measured in automatic mode appear on the display). Or press

and

to set

manually. set “b” valueset nominal diameter “b” marked on the wheel or use the width gauge to measure the

value of “b” as Fig.2, then press

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)
