warnings provided in the service, operation and specification documents of the products with
which this GSP9200 is used (i.e., automobile manufacturers, tire manufacturers etc.).
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.
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
(gasoline).
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 balancer.
Keep all instructions permanently with the unit.
Keep all decals, labels, and notices clean and visible.
To prevent accidents and/or damage to the balancer, use only Hunter GSP9200 Series Vibration
Control System recommended accessories.
Use equipment only as described in this manual.
Never stand on the balancer.
Wear non-slip safety footwear when operating the balancer.
Keep hair, loose clothing, neckties, jewelry, fingers, and all parts of body away from all moving
parts.
Do not place any tools, weights, or other objects on the safety hood while operating the balancer.
ALWAYS WEAR OSHA APPROVED SAFETY GLASSES. Eyeglasses that have only impact
resistant lenses are NOT safety glasses.
Keep the safety hood and its safety interlock system in good working order.
Verify that the wheel is mounted properly and that the wing nut is firmly tightened before spinning
the wheel (or AutoClamp is engaged and secure).
The safety hood must be closed before pressing the green “START” key, located on the right
front corner of the console, to spin the wheel.
Hood Autostart will cause the balancer shaft to spin automatically upon hood closure. For the
next Autostart, the safety hood has to be lifted to the full up position and then closed.
Raise safety hood only after wheel has come to a complete stop. If safety hood is raised before
the spin is completed, the weight values will not be displayed.
Do not let cord hang over any edge or contact fan blades or hot manifolds.
The red “STOP” key, located on the right front corner of the LCD assembly, can be used for
emergency stops.
DANGER: Never reach under the hood while the balancer is performing a runout
measurement or balance spin.

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 keys are identified as:
K1 Key
K2 Key
K3 Key
K4 Key
Menu Shift Key
Start Key
Stop Key
Reset Key
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.
Using Control knob
The control knob is located to the right of the softkeys. The control knob accesses the
on-screen switches and manually inputs data. The available on-screen switches are
dependent upon the setup configuration of the balancer.

changes the setting for the selected on-screen switch.
For example, in the “Balance” primary screen, pushing in on the control knob will cycle
through the grams to ounces, the static and dynamic, and the SmartWeight®/Standard
balance screen switches. After selecting an on-screen switch, the setting may be
selected by rotating the control knob. The “selected” switch is the one showing the hand.
Primary Balancing Display
Resetting the Program
The wheel balancing program may be reset at anytime by using the key, located
on the LCD support console directly beneath the LCD. To reset the balancer, press
the reset key twice within a four-second period without pressing any other keys in-
between. This prevents a single accidental keystroke from resetting the system.
When the balancer is reset, the information collected for the wheel balance in
progress is erased and the display returns to the “Logo” screen.
