2 INSTALLATION AND OPERATION
Before installation and use of the wheel balancer, you
should carefully read this installation and operation
manual. And keep this manual in hand for reference at
any time. You should be sure that all the operators have
read this manual to guarantee the most perfect
functions of the machine and meanwhile the safety.
2.1PROTECTIVE HOOD INSTALLATION:
2.2MAIN SHAFT INSTALLATION
FIG 2
MAINSHAFT INSTALLATION：Before installation, use
the ethyl alcohol and compressed air to clean up the
center hole of the shaft and connect part. Use spanner
and screw to fix the thread shaft on the balance shaft
(Fig2)
2.3 ELECTRICAL CONNECTION & EARTHING
According to the label on the connect between
power cable and body, the power cable connect
socket must be grounded with the reliable earth wire.
All the electrical devices installation must be done by
the qualified staff. Before installation, please check
If the power system is comply with the technical
parameter marked on the nameplate of the machine.
The wiring of the machine must have the fuse and the
perfect ground protection. And install the electrical
Leakage automatic controls switch in the power source.
And recommend the application of the stabilizer
if the voltage of installation site is unstable.
Any electrical connect in the workshop is only done by
the qualified technical staffs and it should meet the
enforced regulation. .
Any electrical connect must be according to the
following:
• Power on the data plate on the machine;
• Voltage decrease can not exceed 4% of the rated
voltage on the data plate when full load (10% when
start)
-Operators must:
• Install the plug;
• install 30ma circuit breaker;
• install power cable fuse;
• provide with effective workshop electrical connect to
ground;
- prevent the authorized operation and pull out the plug
to prolong the working life when not use the machine.
- if the machine directly connected to the power source
through the power board not the plug, we should use
the qualified staffs to operate.

3．3 WORK PRINCIPLE
The micro CPU will provide the normal information if it
checks each unit in the normal situation. And the
operators can execute the balance operation. When
balancing, MCPU can control the rotation of the
balancer tester main shaft through the drive interface.
The unbalance signal sensed by balance sensor is sent
to the micro-processor port through A/D converter. CPU
will integrated analyze the unbalance signal and angle
signal to calculate the unbalance value and display the
value through the LED unit. We can realize the
man-machine talk through keyboard and LED.
