Balancing Your First Tire 1. Turn the machine OFF then ON (resets machine). Note: The machine wakes up using standard clip-on wheel weight locations (c1 & c2) and wheel dimensions. 2. Mount a tire/wheel on the balancer that will use standard clip-on wheel weights. Use the most appropriate mounting method. 3. Always remove any weights already attached to the wheel. 4. Enter A & D wheel dimensions using offset arm.
Principle Operating Parts Know Your Unit Compare this illustration with the unit before placing it into service. Maximum performance and safety will be obtained only when all persons using the unit are fully trained in its parts and operation. Each user should learn the function and location, of all controls. Prevent accidents and injuries by ensuring the unit is properly installed, operated and maintained.
Operating the Balancer Wheel Mounting Select the most appropriate mounting method for the wheel you are balancing. Using the proper method ensures secure mounting and safe balancer operation, and prevents damage to the wheel. On most wheels, the inner side of the wheel hub usually has the most uniform surface for wheel balancing. Always center the wheel by the most uniform shaped side of the hub to achieve the most accurate balance. 4. Thread the hub nut onto the shaft, and tighten it against the wheel.

Pos B For clip-on weights, use gauge in the top position A. For adhesive weights, use the gauge as preferred in top position A or bottom position B. Note: Always use the round part of the striker plate resting on the rim. Indication of dimensions acquired Return the gauge to rest position.
Exact Positioning of the Adhesive Weight by Means of the Gauge with Clips - press Result of Measurement After performing a balancing spin, the amounts of unbalance are shown on the digital readouts. The illuminated LEDs 3 and 4 indicate the correct angular position of the wheel to mount the counterweights (12 o’clock). Correction of inner side - Fit the correction weight in the specific gauge seat with the adhesive part facing upwards.
Behind Spoke (Hidden Weight) The SPLIT function is used to position the adhesive weights behind the wheel spokes so that they are not visible. This function should be used only in the case of static unbalance or where the hidden adhesive weight is to be applied on the outside. Input the wheel dimensions and do a spin. 15 30 - Correction position 1 (indicator 1) Start the SPLIT function as follows: 30 15 - Place the wheel in the outside unbalance correction position.
Match Mount - This function serves to reduce the amount of weight to be added in order to balance the wheel - It is suitable for static unbalance exceeding 1.5oz (30g). TIRE IN POSITION INDICATION - Mark the rim (12 o’clock position). Turn the tire on the rim until the marks correspond to obtain the optimization shown on the display. No previous unbalance measurement Unbalance already measured CANCEL OPTIMIZATION IN ANY PHASE. Unbalance measured - It improves the residual eccentricity of the tire.
Correction Modes To check the type of correction selected, hold the but- From the measurement screen, press or button to select the type required. If a spin has already been performed, the processor automatically recalculates, for each change of mode, the amounts of unbalance according to the new calculation. ton , while on the matrix display the rim symbol appears with the correction weights flashing in the right application position.
Manual Dimension Presetting (Use only in particular cases or for test) c1-c2/STATIC/t1-t3/c1-t3 Wheel Rims (use for setting dimensions in AUTO CALIBRATION) - Preset using distance “A” for the inside of the wheel from the machine. Note: This setting is also valid for the correction modes STATIC/t1-t3/c1-t3. t1-t2 Rims W dt1 dt2 A At1 At2 D To go to these functions: - Setting: Press - Setting: or - press one of the two buttons for more than 2 seconds.

Note: when dt2 is not set, dt2 = dc1 + 2” is automatic. 12 • Important: Always read and follow the instructions.
Self-Calibration For machine self-calibration proceed as follows: - Fit a wheel with steel rim of average dimensions on the shaft. Example 6" x 14" (± 1") - Preset the exact dimensions of the wheel mounted. Display Saver A display saver function can be enabled which allows temporarily replacing the information on the display with moving symbols.
Maintenance Instructions Diagnostic Procedures The balancer requires only minor maintenance to keep the unit operating properly. 1. Keep the display clean and clear. Use a damp cloth. Do not use cleaners or solvents which leave oily or filmy residues behind. After Balance Vibration Problems If vibration is still present after balancing the wheels and driving the vehicle on smooth pavement, remove the wheels and recheck the balance. If a wheel is out of balance the cause maybe: 2.
Installation Instructions Features A factory trained COATS® Service Technician must perform the install, setup, and initial test procedures on your wheel balancer. Do not attempt to install and setup the unit yourself. Accurate and reliable operation of your unit depends on proper installation. Please contact COATS® directly at 1-800-688-9240 for the Certified Service Partner nearest you.
Floor and Space Requirements Unpacking the Unit The balancer must be located on a flat floor of solid construction, preferably concrete. The balancer must sit solidly on its three feet. If the balancer is not level, does not sit solidly on its three feet, or is placed on an unstable floor, the balancer will not function properly and may produce inaccurate balance readings. Do not operate the balancer while it is on the pallet.
Hood Installation 1. Install plastic bushing on end of hood tube. 2. Insert hood tube through hole and slide through hood mounting bracket. The bushing will only fit one way due to its molding. 3. Install second plastic bushing on the end of the hood tube protruding from the bracket. 4. Slide on the stop ring. The set screws may need to be loosened to install slide ring. Adjust the stop ring so the notch is parallel to the floor when the hood is in the down position. 5.
