Direct Drive Connect to Power Three-Phase Your factory trained COATS® Service Technician should do the final check to verify the power installation before connecting the balancer to a power supply. Failure due to improper power connection will void the warranty. Connect the balancer to an appropriate electrical receptacle. Refer to Figure 8 and 9, as well as Electrical Requirements on page 1.
Direct Drive Balancer Operation Overview This machine is a two-plane, microprocessor-based computer balancer. Any imbalance in a wheel, either static or dynamic, is resolved into two correction planes (usually the inner and outer flanges of the wheel) where corrective weights can be applied. Pressing MODE and selecting the DYNAMIC, ALLOY, STATIC, or RV mode can change the location of these planes.

Wheel Measurement Display - Displays A, W, and D values. 2 3 Wheel Offset (A) - The distance between the inner rim flange and the edge of the balancer. Refer to Data Entry beginning on page 9 for detailed instructions. Wheel Width (W) - The width of the rim between the inner and outer rim flanges.
Direct Drive Mounting Wheels 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 uniformly shaped side of the hub to achieve the most accurate balance.
Direct Drive Alternate Mounting If the wheel has a protruding outer hub which will not permit the use of the pressure cup, or the cup will not permit the hub nut to engage at least four turns of the arbor, this alternate method should be used. Spring No Mar Ring 1. Place the cone spring on the arbor with the large end towards the balancer. 2. Select the cone that best fits the center hole in the wheel. Slide the cone onto the arbor with the large end towards the spring. Cone 3.
Direct Drive Wheel Data Entry Before a wheel can be balanced, the size of the wheel must be entered into the computer. The user enters the data either automatically or manually. Wheel Offset - A This is the distance between the edge of the balancer and the inner edge of the wheel. 1025 1. For Automatic Entry - Pull the distance gauge out from 1050 the side of the balancer. Rotate it until the handle end of the 1055 gauge contacts the inner wheel flange.
Direct Drive Selecting Balancing Mode Eight separate balancing modes are available on the 1050S. Select the balancing mode based on wheel type and customer request. Press the mode key to select the desired balance type. The LED will illuminate to indicate your selection. In the alloy and static modes, the balancer will automatically adjust the wheel diameter to compensate for the actual location of the weight(s). Dynamic Balancing Alloy 3 The most common mode used for passenger cars and light trucks.
Direct Drive Selecting Balancing Options Hood Start The balancer can be set to automatically start the spin cycle as soon as the hood is lowered completely and the hood safety interlock systems are engaged. Press and hold the SHIFT key and press 3. To return the balancer to normal mode, repeat the key sequence. Round Off The default weight measurement on the balancer is 0.25 ounces. The balancer can be set to a non-Round Off mode that displays weights in 0.01 ounce increments.
Direct Drive Balancing a Wheel Checking the Balance Procedure The following steps walk through the balancing procedure. Do not proceed with these instructions until you have read and understand the previous sections of this guide (mounting, balance modes, and reading the displays). 1. Turn the balancer on. The power switch is on the rear of the unit, near the top and to the operator's left.
Direct Drive Match Mount Description The Match Mount program assists the user in determining the best possible mating of the tire and wheel, thereby reducing the amount of additional weight required for balancing. This mating of tire and wheel normally allows the least amount of total runout of the assembly, resulting in better balancing, better ride conditions, and more satisfied customers. Use Match Mount when: • Excessive radial runout is noticed in the tire and wheel assembly during balancing.
Direct Drive 14. Replace the valve core and inflate the tire. Follow the tire changer manufacturer's instructions for inflation. 1025 Remember: If another operator memory has been select1050 ed, reselect the memory being used for the Match Mount 1055 procedure. The balancer will return to the point in the pro- Tire/wheel assembly rotated until valve stem is at top-deadcenter cedure where the other memory was selected. 15. Remount the wheel on the balancer. 16. Press (2) on the control panel.
Direct Drive Maintenance and Calibration Preventative Maintenance The balancer requires only minor maintenance to keep the unit operating properly. 1. Keep the display clean and clear. Use a vaporizing cleaner only. Do not use cleaners or solvents, which leave oily or filmy residues behind. 2. Keep the adapters, cones, faceplate, threaded arbor, pressure cup, and hub nut clean. Grease and dirt buildup will cause premature wear and inaccurate balancing. Clean at least once a day with a vaporizing solvent. 3.
Direct Drive 1025 1050 Distance Gauge Calibration 1055 1. Securely mount your calibration wheel. 2. Press and hold SHIFT and press 0. The display will read CDE to indicate it is ready for a code. 3. Press 1 then 0. The inner weight display will now read 0.08 to 0.22 and the outer weight display will read 0.55 to 0.70. 4. Rotate the distance gauge to its maximum rotation (towards the front of the balancer) and hold it there. 5. Press MODE. 6.
