4. Tire Balance operation
4.1 After the power is turned on and the device code is displayed, the
display window displays "8.0 5.7 14.0", which proves that the
machine is normal.
4.2 Installation of Wheels
(1) preparation before the test: check and remove the dust, soil and
tread of the tire whether there are metal, stone and other foreign
bodies; Check whether the tire pressure is in line with the specified
value; Check whether the positioning surface and mounting hole of
the rim are deformed, check whether there are foreign bodies in the
tire; Remove the original balance block.
(2) There are three types of wheel installation, including positive
positioning, reverse positioning and additional flanges for large and
medium tires. A positioning method can be selected arbitrarily
according to the actual situation.
4.2.1 forward positioning
Spindle - Wheels (rim mounting face
inwards)- Fit cone (small head
inwards)- Wheels - Quick nut
forward positioning is a common positioning
method, the operation is simple and fast, mainly suitable for
ordinary steel ring and thin aluminum alloy ring, this
positioning is suitable for the steel ring deformation is
small。

4.2.2 Reverse p o s i ti o n i n g
Spindle - spring - fit cone (big head inward)- wheel - quick nut
4.2.3 Special flange positioning
Fix the large flange to the matcher - wheel - large cone - quick nut
4.3 Size of the input
4.3.1 Input steps:
ⅠFirst enter the size "a"
This positioning method is suitable for the
wheel center hole Φ148 below the tire
installation.
Note: the choice of cone should be adapted to the center hole of the rim, and pay
attention to its direction, otherwise it will cause inaccurate measurement.
When the wheel outside deformation is large,
the reverse positioning is used to ensure the
accurate positioning of the inner hole and spindle
of the steel ring. It is suitable for steel ring,
especially for measuring thick aluminum alloy
ring.
The distance measuring ruler of the machine itself is used to
measure the distance between the body of the balancing machine
and the rim of the inner edge "A" value
