1.4 Operating the Console
Using Softkeys
The “softkeys,” located on the LCD support console directly beneath the LCD,
provide operator control of the balancer.
The four menu labels that appear at the bottom of each video screen are referred to
as the “softkey labels.” Each label indicates the action that the program takes when
the corresponding K1, K2, K3, or K4 key is pressed.
The display between the “K2” and “K3” labels indicates how many rows of labels are
available. Most screens have only one or two rows, however more rows are possible.
The green box indicates the row that is currently displayed.
The menu row is changed by pressing the menu shift key, . When this key is
pressed, the menu labels change to the next row down. If the last row is currently
displayed, the menu labels change to the first row.
Throughout this manual, the statement press “nnnnnnn” means press the softkey
with the label “nnnnnnn.” If the required label is not on the current menu, press to
change rows until the desired label is displayed.

2. Balancing Overview
2.1 Balance Forces
Balancing Theory - Static Imbalance
As the word static implies, the tire will be balanced when at rest. For example, if an
unmoving assembly was centered on a cone and was balanced, it would be statically
balanced. A “bubble balancer” is designed to statically balance a tire/wheel
assembly.
IMBALANCE
FORCE
FRONT VIEW
STATIC IMBALANCE
CUPPING
Static imbalance is where there is one amount of weight located in the center of the
tire/wheel assembly causing an imbalance. As the weight rotates, centrifugal forces
are created causing the wheel to lift as the weight reaches top dead center. This
lifting motion causes the tire/wheel assembly to move “up and down” creating a
bounce to be felt. This static imbalance condition is evident by a “jiggle” or up-down
movement of the steering wheel. These vibrations may also be apparent in the body,
with or without steering wheel shake.
A statically imbalanced tire driven for an extended period may cause “cupping” in the
tire’s tread, create vibration, and adversely effect handling.
Static balancing alone is a seldom-recommended procedure. For example, a single
weight is commonly placed on the inner clip weight position for cosmetic purposes.
This is not a recommended practice and usually insures the assembly is not properly
dynamically balanced. The assembly may then experience side-to-side imbalance
while in motion, causing a shimmy condition and objectionable vibration.

20

2. Balancing Overview GSP9200 Series Wheel Balancer Operation Instructions
Balancing Theory - Couple Imbalance
Basically, dynamic imbalance is defined as a condition where one or more locations
of the tire/wheel assembly are heavier causing an imbalance force and/or an
imbalance wobble. Shown below is a tire/wheel assembly with two heavy spots of
equal weight which are located 180 degrees radially from each other on opposite
sides. As this assembly rotates, centrifugal forces cause a large imbalance wobble to
be created, but the imbalance force (as well as the static imbalance) will be zero. A
wheel with this condition will cause a wobble or shimmy to be felt in the steering
wheel. Excessive dynamic imbalance of this type creates a shimmy that transfers
through the suspension components to the occupants of the vehicle, especially at
higher speeds.
IMBALANCE WOBBLE
(LATERAL TWIST OR TORQUE)
FRONT VIEW
ZERO STATIC IMBALANCE WITH LARGE
COUPLE IMBALANCE
Modern “dynamic” balancers spin the wheel in order to measure both the up and
down imbalance force and the wobble or shimmy related imbalance (side-to-side).
Dynamic balancers direct the operator to place correction weights on the inside and
outside correction locations of the rim so that both imbalance shake (static) and
imbalance wobble (couple) will be eliminated.
