BALANCER OVERVIEW
This machine is a two-plane, microprocessor-based computer
balancer. Any imbalance in a wheel, either static or dynamic,
is detected into two correction planes (the inner and outer)
where corrective weights can be applied. Pressing the
F
button selects either
DYNAMIC or STATIC modes and
pressing the
ALU button selects the ALU modes,all ofwhich
change the location of the planes.
Determining the Planes
When the distance gauge is pulled out and held against
the wheel flange, the distance measurement shown on the
pull out slide refers to the
DISTANCE OFFSET
MEASUREMENT. This measurement tells the computer
the location of the
INNER plane of the wheel for Dynamic
and/or Alloy balancing.
By using the
WHEEL CALIPERS and / or the OUTER
GAUGE-ARM, the wheel width or the WIDTH MEASUREMENT
tells the computer the location of the
OUTER plane of the wheel
for Dynamic and/or Alloy balancing.
The wheel diameter will be referred in this manual as the
DIAMETER MEASUREMENT. This is the diameter of the
wheel at the weight location. You can determine the diameter
of the wheel / tire on the tire sidewall to determine the wheel
diameter. Or you can use the calipers. This tells the computer
how far from the center of the hub the weights will be applied.
Balancing a Wheel
When a wheel is spun, the balancer detects any imbalance
present. The computer calculates the weight needed to
correct the imbalance and the location for weight application.
The weight required to correct the imbalance is displayed on
the control panel, and the weight positioning lights assist the
operator in positioning the weight application location at
top-dead-center. Weight displays and positioning lights are
provided for both inner and outer planes of the wheel.
