14. Maintenance
14.1 The daily maintenance of non- professionals
Before the maintenance, please switch off the power-supply.
13.1.1 Check whether the wire of electricity part connects reliably.
13.1.2 Check whether the pressed screw of the main axis is loose
13.1.2.1 Locking nut cannot fix wheel tighten on main-axis
13.1.2.2 Use hexagonal wrench to tighten the pressed screw of the main-axis.
14.2 The maintenance of professionals
The maintenance of professionals can only be carried out by the professionals from the
factory
14.2.1 If the imbalance value of tested wheel has obvious errors and does not improve
after self-calibrating, this proves the parameter in the machine has altered, so the
user should ask for professionals
14.2.2 The replacing and adjustment of pressure sensor should be operated according to
the following methods, and the operation should be carried out by
professionals
The steps are as follows:
1. Unlash the No.1, 2,3,4,5 nuts.
2. Dismantle the sensor and nut.
3. Replace No.6, 7 the sensor organ.
4. Install the sensor and the nut according to the Fig 14-1. (Pay attention to the sensor’s
direction.)
5. Tighten No.1 nut emphatically.
6. Tighten the No.2 nut to make the main axis and the flank of cabinet, and then
emphatically tighten the No.3 nut.
7. Tighten the No.4 nut (not too emphatically), then tighten No.5 nut.
14.2.3 The replacing of circuit board and the organ on it should be carried out by
professionals
Hint: check precision right method:
Input right date of wheel(a. b. d value),consult instruction do a
self-calibration, process balance operation, note down date of first
time, clamp 100 gram counterweight on the outside edge of
wheel(when outside indicator light all on is top zenith position), again
process balance operation, this data of outside display addition data
of first time, should be 100±2, manually slowly rotate the wheel, when
light of outside all on, check 100 gram counterweight whether at 6
o’clock position, if value is not 100 gram or 100 gram counterweight is
not at 6 o’clock position, balancer precision has problem, if amount is
100 gram, follow same method check inside, check inside whether
amount is 100 gram and at 6 o’clock.
