CONTENTS GSP9200 Series Wheel Balancer Operation Instructions...
1.1 Introduction This manual provides operation instructions and information required to operate the GSP9200 Series Balancer. Read and become familiar with the contents of this manual prior to operating the GSP9200. The owner of the GSP9200 is solely responsible for arranging technical training. The GSP9200 is to be operated only by a qualified trained technician.
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.
Decal 128-605-2-00 cautions the user that spindle rotation may occur with foot pedal ® depression and to keep clear of clamping components during Quick-Thread shaft rotation. Auto-Clamp models will have decal 128-1123-2 instead. 1. Getting Started x 3 GSP9200 Series Wheel Balancer Operation Instructions...
Decal 128-229-2 and decal 128-905-2 work in conjunction to caution the user to not remove the screw because of the risk of electrical shock. 4 x 1. Getting Started GSP9200 Series Wheel Balancer Operation Instructions...
NEMA L6-20P. This machine must be connected to a 20 amp branch circuit. Please refer all power source issues to a certified electrician. Refer to “Installation Instructions for GSP9200 Series Vibration Control System,” Form 5110T.

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. 10 x 1. Getting Started GSP9200 Series Wheel Balancer Operation Instructions...
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. 1. Getting Started x 11 GSP9200 Series Wheel Balancer Operation Instructions...
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. 2. Balancing Overview x 1 GSP9200 Series Wheel Balancer Operation Instructions...
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. 2 x 2. Balancing Overview GSP9200 Series Wheel Balancer Operation Instructions...
® NOTE: SmartWeight balancing performs this check automatically. For detailed information on adjustment and setup of modes of wheel balancing sensitivity see Chapter 4, Balancing Features and Options. 2. Balancing Overview x 3 GSP9200 Series Wheel Balancer Operation Instructions...
The SmartWeight tire graphs will display red for excessive forces and green for acceptable amounts of force. Prior to measurement the tire graphs will display no color. 4 x 2. Balancing Overview GSP9200 Series Wheel Balancer Operation Instructions...
The following example is set at the default of 75%. A 75% residual goal ® means that WeightSaver allows 75% of the maximum allowed couple force to remain. This saves more weight, saves time, and saves money. 2. Balancing Overview x 5 GSP9200 Series Wheel Balancer Operation Instructions...
If the wheel has no appreciable movement around or about the centerline of the hub, it should be considered hub centric. A hub centric wheel will have very little (0.003 – 0.004”) clearance or a slip fit to the hub. 6 x 2. Balancing Overview GSP9200 Series Wheel Balancer Operation Instructions...
To verify if the wheel is lug centric: Remove the lug nuts (or bolts) and try to move the wheel up/down and side/side on the hub. A lug centric wheel will display noticeable movement. 2. Balancing Overview x 7 GSP9200 Series Wheel Balancer Operation Instructions...
Slowly roll the wheel towards you while tightening the wing nut. This improves accurate wheel centering, since the wheel is allowed to roll up the taper of the cone as opposed to forcing it to slide up the cone. 3. Balancing Procedures x 9 GSP9200 Series Wheel Balancer Operation Instructions...
To remove the Auto-Clamp assembly, slightly tap the Spindle-Lok® foot pedal twice to release the pneumatically powered spindle. Squeeze the levers to disconnect the Auto-Clamp locks from the spindle, and slide the assembly off the spindle. 10 x 3. Balancing Procedures GSP9200 Series Wheel Balancer Operation Instructions...
