INSTALLING THE THREADED MAIN SHAFT 4. Slide the Hood Arm over the Hood Axle, align the holes in the Axle with the Allen bolts then secure in place using the two allen set screws. 1. Locate the Face Plate / Threaded Main Shaft and mounting bolt in the accessory box and install as shown. 5. Raise the hood and hold it up. Use help to hold the hood while attaching the hood to the Hood Arm. 6.
BALANCER OVERVIEW The wheel diameter will be referred as the DIAMETER MEASUREMENT. This is the diameter of the wheel at the weight location. You can determine the diameter of the wheel / tire on the tire sidewall to determine the wheel diameter. Or you can use the calipers. This tells the computer how far from the center of the hub the weights will be applied. This machine is a two-plane, microprocessor-based computer balancer.
SELECTING WEIGHT POSITIONS FOR DIFFERENT WHEEL TYPES GRAM / OUNCE SELECTION This machine is capable of registering GRAM or OUNCE readings. To select either GRAM or OUNCE settings, follow the procedures below. Prior to balancing, a specific FUNCTION must be chosen for each particular wheel. The function settings automatically compensate weight location requirements for a particular wheel type. These settings can be selected by depressing the F button. 1. First press the “STOP” button.
MOUNTING WHEELS Front Cone Mounting Select the most appropriate mounting method for the wheel you are balancing. Using the proper method ensures secure mounting, accurate displays and safe balancer operation. It also 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.
Dual Cone Mounting Some aftermarket or OEM performance wheels have a center hole that is deep enough to allow the use of two cones to mount it to the threaded shaft. The factory recommends that dual cone mounting is used in this situation. The cones must not contact each other and a correct cone combination is critical to correctly mount a tire using this method. (Extra centering cones are available though Ranger Products) 1. Slide the Spring onto the Arbor. 2.
BALANCING INSTRUCTIONS 1. First determine which mounting method you will use for the wheel. 2. Select a centering / mounting cone that best fits the center hole of the wheel. Inputting Wheel Data Prior to balancing any wheel, specific data relating to that particular wheel must be entered into the computer. If the data displayed on the screen does not match that of the wheel you are attempting to balance then the wheel will not be accurately balanced.
“dia” - Wheel Diameter 4. Pull the index arm out from the side of the machine until the tip touches the inner edge of the wheel. This is the diameter of the wheel at the rim flanges. This measurement can be read on the tire sidewall. Or measured. To enter Wheel Diameter data, refer to the instructions below. 1. Read the diameter of the wheel as shown on the tire sidewall. Or use the Calipers to measure the wheel diameter. (Use the proper scale for Wheel Diameter) 5.
2. After the hood is lowered, or the START button is depressed, the wheel will spin for approximately six seconds then stop automatically. 3. After the wheel stops, weight readings for each side of the wheel (INNER and OUTER) will appear in the center display screen. 6. After the INNER weight is properly installed, turn the wheel by hand until the weight position indicator lights on the side marked OUTER are fully illuminated.
STOP BUTTON Spin Mode / STATIC This function is used if weights can only be mounted on a single plane of the wheel. 1. Once the correct wheel data has been programmed, lower the hood to begin the spin mode. 2. After the hood is lowered, or the START button is depressed, the wheel will spin for approximately six seconds then stop automatically. 3. After the wheel stops, a weight reading will appear in both center display screens. The weight reading will appear the same in both screens. 4.
TROUBLE SHOOTING GUIDE. Perform the following checks if you are experiencing balancing problems. PROPER INSTALLATION / ASSEMBLY Confirm that the balancer is bolted down. Confirm the location and alignment of the witness marks on the Face Plate and Shaft Assembly. (See Page 7.) CALIBRATION It is recommended to perform the Weight Location Verification on a monthly basis following procedure that can be found on page 17 in the manual. The calibration MUST be performed with a 14” or 15” steel wheel with a tire.
WEIGHT LOCATION VERIFICATION PROCEDURE SELF-CALIBRATION PROCEDURE NOTE: Before performing the self-calibration procedure, make sure the balancer is bolted down and/or rigid to the floor and that the shaft and centering cones are clean and undamaged. Even the slightest dirt or damage can cause inaccurate readings. PAY CLOSE ATTENTION to the following procedure. If not followed correctly, the balancer will not perform accurately. This balancer should be checked every 30 days.
PROCEDURES FOR CHANGING PARAMETER SETTINGS 3. Using an Allen Wrench, remove the Distance Arm from the Distance Arm Assembly. The Distance Arm Shaft will retract into the Balancer Cabinet. NOTE: It is only necessary to modify the Parameter Settings if the computer/display board was replaced or if the calibration procedure does not resolve balancer problems. NOTE: These settings must match the Parameter Setting Sticker located inside of the balancer.
6. Carefully support the Weight Tray while noting the Parameter Setting Values located on the Parameter Settings Sticker located on the inside wall of the front panel of the machine. 7. Note the Parameter Setting Values before reassembly, they will be needed after cover is closed. 8. Reassemble the Weight Tray and Distance Arm and proceed to resetting the Parameter Settings.
RESETTING PARAMETER SETTINGS 7. When checking/modifying the “dIS” setting is complete, press Distance + button below move on to the next parameter setting. 1. Press and hold the R button and the NOTE: Once you move on to the next parameter setting, you must restart this procedure if you would like to edit the dIS value again. at the same time until the Start button 8. The Screen should now display “In.” on the Inner and a 3 digit number on the Outer. weight position indicators stop flashing. 2.
14. Press the + or - button below to modify the values to match the values shown on the Parameter Settings Sticker. 15. When checking/modifying the SFA setting is complete, press Distance + button below the next parameter setting. to move on to 16. Once you are done checking/modifying the SFA setting, press Distance + to move save the changes. NOTE: Once you move on to the next parameter setting, you must restart this procedure if you would like to edit the SFA value again.
1. Balancer Shaft Does Not Rotate. 1. A wheel is not installed on the balancer. 2. A wheel is installed on the balancer but there is no tire. 3. The quick nut is not tight and/or the wheel is not correctly installed on the balancer. 4. The Electrical Motor belt tension is not correct. 1. The wheel/tire combination has to large of an unbalance. 1. The wheel is rotating counter clockwise. 2. The wheel is rotating clockwise and the Encoder Board is malfunctioning. 1. The protective Hood is Open. NA 1.
