This document describes the Aston Magnetic Levitation Wheel Balancer AWB-139ML, a device designed for balancing vehicle wheels. The manual provides comprehensive instructions for installation, operation, and maintenance, emphasizing safety precautions throughout.
Function Description
The Aston Magnetic Levitation Wheel Balancer AWB-139ML is a sophisticated machine used to measure and correct imbalances in vehicle wheels. By spinning the wheel, it detects uneven weight distribution and calculates the precise amount and location of weights needed to achieve balance. The device supports various balancing modes, including standard dynamic balance, static balance, and specialized ALU programs for alloy wheels. Its magnetic levitation system aims for high accuracy in measurements.
Important Technical Specifications
While specific numerical technical specifications like power consumption or motor speed are not detailed in the provided pages, the manual highlights several functional aspects:
- Balancing Modes: Standard Dynamic Balance, Static Balancing, ALU Programs (ALU1-ALU5), and ALU-S (Variable Plane Program).
- Weight Units: The device can display weight in grams (g) or ounces (oz), selectable by the user.
- Data Entry: Supports both manual and automatic data entry for rim distance (A), rim width (W), and rim diameter (D). Automatic data entry models feature electronic measuring arms and an optional sonar device for width measurement.
- Weight Application: The machine indicates weight positions for both clip-on and stick-on weights, depending on the selected ALU program.
- User Presets: Allows saving up to four different user data presets for wheel dimensions (A, W, D) to expedite operation for frequently balanced wheel types.
- Safety Features: Includes a protection hood that must be lowered to activate a spin cycle, and a STOP key for emergency termination of spin. The machine warns against operating without the hood or raising it before the wheel stops.
- Calibration: The device supports calibration for balancing, distance A, diameter D, and width W to ensure accuracy.
- Special Programs:
- HIDE SPLIT Weight Program: Available with ALU-S mode, this program splits a single outer weight into two hidden weights placed behind spokes for aesthetic purposes on alloy rims.
- OPT-Match Mount Program: Designed to reduce the amount of weight needed for balancing, particularly for static unbalance exceeding 30 grams (1.5 oz). This involves remounting the tire on the rim by 180 degrees to optimize weight distribution.
- Motorcycle Wheel Balancing: Supports balancing for motorcycle wheels, requiring specific adaptors.
Usage Features
- Display Overview: The device features clear display windows for inner (left) and outer (right) weights, rim distance (A), rim width (W), and rim diameter (D). Indicators show active functions (OPT, HIDE), weight units (ounce, gram), vehicle mode, and balancing mode.
- Keypad Overview: A well-defined keypad with dedicated keys for various functions, including START, STOP, USER, SPL (Smart Position Locator), HIDE, <T (fine unbalance reading), Fn (Function/Static), ALU, C (Recalculate/Exit Program), and directional keys (A+, A-, W+, W-, D+, D-) for data input.
- Mounting a Wheel: Detailed instructions are provided for mounting wheels using back centering-cone, front centering-cone, and optional universal adaptors for wheels without a center hole. Emphasis is placed on selecting the correct centering-cone size and securely tightening the hub nut.
- Data Entry: Users can manually input A, W, and D values using the measuring arm and keypad, or utilize automatic data entry features on equipped models.
- Weight Position Search: Two methods are available: manual search, where the user rotates the wheel until indication bars illuminate, and automatic search (SPL), which automatically positions the wheel for weight application.
- Laser Pointer (for ALU-1): Some models feature a laser pointer that indicates the precise location on the wheel where the correction weight should be applied.
- System Alarm Codes: The manual lists various alarm codes (Err -1 to Err -9) with corresponding definitions and troubleshooting steps, such as "Wheel hood opened when start key pressed" or "Motor is over load."
Maintenance Features
- Calibration: Regular calibration (every 3 months or after relocation/temperature changes) is crucial for maintaining the machine's accuracy. The manual provides step-by-step procedures for balancing calibration, distance A calibration, diameter D calibration, and width W calibration.
- Owner's Responsibility: The owner is responsible for ensuring proper installation, regular inspection, adherence to safety instructions, proper training of operators, and using only manufacturer-recommended accessories and replacement parts.
- Work Area: Maintaining a clean, well-lit, and dry work area is recommended.
- Warranty: The device comes with a one-year warranty on operating components, covering defects in material and workmanship. It specifies conditions for warranty claims, including freight prepaid returns and labor costs for the first 12 months. The warranty does not cover defects from ordinary wear, abuse, misuse, shipping damage, improper installation, or lack of required maintenance.
This wheel balancer is designed for professional use, offering precision and a range of features to handle various wheel types and balancing requirements efficiently and safely.
