Do not operate equipment with a damaged cord or equipment that has been dropped
or damaged until a Hunter Service Representative has examined it.
Always unplug equipment from electrical outlet when not in use. Never use the cord
to pull the plug from the outlet. Grasp plug and pull to disconnect.
If an extension cord is necessary, a cord with a current rating equal to or more than
that of the equipment should be used. Cords rated for less current than the
equipment may overheat. Care should be taken to arrange the cord so that it will not
be tripped over or pulled.
Verify that the electrical supply circuit and the receptacle are properly grounded.
To reduce the risk of electrical shock, do not use on wet surfaces or expose to rain.
Never direct a hose stream at equipment when cleaning.
Verify the appropriate electrical supply circuit is the same voltage and amperage
ratings as marked on the balancer before operating.
WARNING: DO NOT ALTER THE ELECTRICAL PLUG. Plugging the
electrical plug into an unsuitable supply circuit will
damage the equipment and may result in personal
injury.
To reduce the risk of fire, do not operate equipment near open containers of
flammable liquids or sprays (gasoline, cleaners, fluids, etc.).
Read and follow all caution and warning labels affixed to your equipment and tools.
Misuse of this equipment can cause personal injury and shorten the life of the

2. BALANCING OVERVIEW
2.1 Balancing Modes
Static Balance
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 that balances the
assembly using only a single weight plane. 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.

Dynamic Imbalance
In general terms, dynamic imbalance is defined as 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.

ZERO STATIC IMBALANCE WITH LARGE
DYNAMIC (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 force and imbalance
wobble will be eliminated.

2. Balancing Overview DSP9200 Series Balancer Operation Instructions

Static and Dynamic Imbalance Sensitivity
As a general rule of thumb, to achieve the best balance on an average sized tire and
wheel assembly:
Residual static imbalance should be less than 1/2 ounce.
Residual dynamic imbalance should be less than 1/4 ounce per plane.
A small amount of residual dynamic imbalance is preferred over a similar amount of
remaining static imbalance.
In general, it takes much more residual dynamic imbalance to cause a vibration than
the same amount of static imbalance.
The larger the diameter used for weight placement, the smaller the amount of
correction weight is required.
The wider the distance between the two weight placement locations, the smaller the
amount of correction weight is required.
If static balance is the only option, always verify that the remaining dynamic residual
imbalance is within acceptable tolerance.
2.2 Identifying the Static Balance Weight Plane
In “STANDARD BALANCE” mode, using only a clip-on weight, the plane is input as
follows:
For static balancing, it is recommended that you place half of the correctional weight
value on each side of the tire to reduce residual dynamic imbalance.
In “MIXED WEIGHTS BALANCE” mode and “ADHESIVE WEIGHTS BALANCE”
mode, using an adhesive weight, the plane is input as follows:
DIAMETER
For static balancing, it is recommended that the adhesive weight be placed as close
to the center of the wheel as possible to reduce residual dynamic imbalance.

In “PATCH BALANCE” mode, using a patch weight, the plane is input as follows:
DIAMETER
For static balancing, it is recommended that the patch weight be placed as close to
the center of the tread as possible to reduce residual dynamic imbalance.
2.3 Identifying the Dynamic Balance Weight Planes
The balancer must know the location of the two weight circle planes for placement of
correction weights on the wheel assembly.
Each plane is described by a distance from the balancer and a diameter.
