The machine also includes an integrated centering spring on the balancing shaft and storage pegs for accessories.

Detailed Description

The balancer uses a rotating shaft and electronic measurement system to detect where a wheel assembly is out of balance. After the operator enters the wheel distance, rim width, and rim diameter, the machine calculates the correction weight for each balancing plane.

Major components include the power cable and plug, side panel, hood return spring, magnetic hood switch, measurement scale, control panel, weight tray, protective hood, quick nut, balance shaft, machine body, power switch, and cone-storage handle.

The control panel contains separate displays for inner and outer imbalance values, position indicators, balancing-mode lamps, measurement keys, unit conversion, high-accuracy display, function and confirmation controls, an emergency stop, and the start button.

Safety

• Use the ATD-WB Wheel Balancer only for wheel balancing and only by authorized, trained personnel.
• Do not modify, bypass, remove, or tamper with any safety device. The machine includes a rotation-stop control and a protective hood system.
• Keep the work area visible, clear of hazards, and restricted to authorized personnel.
• Install the balancer on a level, load-bearing floor, preferably concrete. Avoid ceramic tile, gravel, explosive atmospheres, and fire hazards.
• Electrical connections and work on internal electrical components must be completed by qualified personnel.
• Verify the supply voltage, wiring condition, grounding conductor, and dedicated 30 A circuit before use.
• Disconnect the plug before moving the machine, performing repairs, or working on the motor, wiring, or internal electrical parts.
• Keep warning and instruction labels legible.
• Before balancing, remove old wheel weights and inspect the tire, tread, rim surface, and mounting holes. Remove embedded dirt, mud, and debris and confirm that tire inflation meets the applicable specification.
• Confirm that the quick nut is tight before starting a spin.
• Never strike the main shaft heavily when installing or trimming weights because impact can damage the sensor.
• Keep weight-attachment surfaces clean and dry.

Setup and Installation

Unpacking and placement

After removing the packaging, inspect the machine and accessories for visible damage. Check the accessory box carefully before discarding packing materials. Keep plastic, foam, nails, screws, and wood away from children and dispose of them through suitable collection services.

Leave at least 24 inches of working clearance on each side. Place the machine where the operator can see both the balancer and the surrounding work area. The floor must be horizontal and strong enough to carry operating loads.

Installing the threaded shaft

1. Clean the shaft center hole and connector with ethyl alcohol and compressed air.
2. Attach the threaded shaft to the balance shaft with the supplied screw and a hex wrench.
3. Ensure the shaft and connector are seated correctly before mounting a wheel.

Electrical connection

The standard machine requires a 110 V, 60 Hz, single-phase supply. Install the supplied plug on the power cable as required by applicable electrical regulations. The circuit should be dedicated and protected by a 30 A breaker, and the machine must be electrically grounded.

Disconnect the power plug whenever the balancer will remain unused for an extended period. If the machine is wired directly to a panel without a plug, a keyed switch must be installed so use is limited to qualified personnel.

Mounting the Wheel

Three mounting arrangements are available. Select the method that best matches the rim design and condition.

Positive positioning

This is the common method for standard steel rims and aluminum-alloy rims with minor imperfections. Place the wheel on the main shaft, select the correct cone, and secure the assembly with the quick nut.

Negative positioning

Use this arrangement when the outside of the wheel has imperfections or when more accurate location through the inner hole is required. It is suitable for steel rims and thicker aluminum rims and uses the appropriate cone, wheel bowl, and quick nut arrangement.

Flange-disc positioning

This optional method is intended for tire assemblies with large center holes. The flange disc is fixed to the main shaft before the wheel, cone, and quick nut are installed. Choose the cone according to the rim center hole and orient it correctly; an incorrectly oriented cone can produce inaccurate measurements.

Operating Procedure

Enter the three wheel measurements

1. Distance: Pull the built-in scale to the inner balancing position, read the distance, press the distance input key, and adjust the displayed value with the up or down controls. The default distance unit is millimeters.
2. Rim breadth: Measure the rim width with the supplied caliper, press the breadth input key, and enter the value. The default breadth unit is inches.
3. Diameter: Confirm the rim diameter, press the diameter input key, and enter the value. The default diameter unit is millimeters.

The unit conversion control changes displayed rim breadth and diameter values between inches and millimeters and changes imbalance readings between grams and ounces. The machine returns to its normal inch setting for the applicable rim dimensions after being switched off.

Start a balancing cycle

1. Confirm the tire dimensions and choose the appropriate balancing program.
2. Make sure the wheel is correctly centered and the quick nut is tight.
3. Press the start button, or lower the protective hood if automatic hood-start operation has been enabled.
4. For large tires, gently help the wheel begin turning by hand to reduce motor strain.
5. Wait for the automatic spin to finish and read the inner and outer imbalance values.

Locate and install correction weights

Rotate the wheel by hand after the spin. When all lamps on the applicable position indicator illuminate, the highest point identifies where the corresponding weight belongs. The left indicator identifies the inner correction position, while the right indicator identifies the outer correction position.

Install the displayed weight at the indicated location, then run another test. Repeat the process until the tire assembly reaches the desired balance. Use the supplied hammer gently when securing clip-on weights, and keep the attachment area free of grease and moisture.

Balancing Modes

• Dynamic: Applies clip-on weights to both sides of the rim.
• Static: Applies a single weight at the center plane of the rim.
• MOT: Motorcycle wheel mode. The optional MJ-II motorcycle adapter is required, and the extension scale is used to measure distance, breadth, and diameter.
• ALU1: For light aluminum-alloy rims, with adhesive weights placed on the rim shoulders.
• ALU2: For aluminum rims where the correction weight is hidden on the inside.
• ALU3: Clips the inner weight while placing the outer correction at the same position used by ALU2.

If no mode lamps are illuminated, the machine is operating in dynamic mode.

High-Accuracy and Residual Imbalance Display

When the display reads zero, press the high-accuracy balance key to view imbalance values below 0.25 oz. The standard weight resolution is 5 g, so values below 5 g normally appear as zero. Press the residual-value control when a more detailed reading is needed; the maximum residual imbalance shown by this function is 4 g.

Configuration Functions

Changing weight resolution

The function menu allows the operator to change ounce resolution from 0.1 oz to 0.25 oz or gram resolution from 1 g to 5 g. Use the Home key to enter the function area, select the setup option with the distance controls, choose the desired resolution, and confirm the selection through the Home key.

Factory reset

A factory reset is available through the setup sequence. The procedure requires entering setup, selecting the position and code values shown by the machine, matching the displayed distance value to the physical distance-gauge reading, setting the specified electronic value to 007, and confirming through the Home key until the machine beeps. Switch the machine off and back on after the reset is complete.

Factory calibration

1. Enter the setup area with the Home key and distance-plus control.
2. Use the Home key to reach the position display.
3. Rotate the wheel slowly by hand until the display reaches position 110, then press the high-accuracy key.
4. Continue rotating to position 120 and press the high-accuracy key again.
5. Start the machine with the start key or protective hood. When the display calls for the calibration weight, rotate the wheel until the outer indicators illuminate.
6. Attach the supplied 100 g (3.5 oz) calibration weight to the outside rim at the 12 o’clock position and run the machine.
7. Remove the weight, rotate the wheel until the inner indicators illuminate, and attach the same weight to the inside rim at the 12 o’clock position.
8. Run the machine again. Three beeps indicate that factory calibration is complete.

Cleaning and Maintenance

• Cleaning and routine maintenance must be performed by authorized personnel.
• Keep the flanges clean and dry. Do not lubricate them, and avoid damaging their surfaces during handling.
• Clean the machine and weight tray with a soft cloth lightly moistened with ethyl alcohol.
• Do not use water, other liquids, or compressed air to clean the machine.
• Disconnect the power cable before repairs or maintenance.
