This document is a service manual for the Panasonic AC/Rechargeable Shaver, Model No. ES4853, intended for the Asia market. It provides comprehensive information for experienced repair technicians, covering the device's function, technical specifications, usage, and maintenance.
Function Description:
The Panasonic ES4853 is an AC/Rechargeable Shaver designed for personal grooming. It operates as a cordless device, powered by a rechargeable battery, but can also function while connected to an AC power source via its charging adaptor. The shaver features a motor that drives the inner blades, which work in conjunction with an outer foil to cut hair. A switch controls the motor's operation, and an LED indicates charging status. The device is designed for wet/dry use, indicated by the "WASHABLE" marking on its body, suggesting it can be cleaned with water. It also includes a trimmer for more precise grooming.
Important Technical Specifications:
- Power Source: AC 100-240V, 50-60Hz (Automatic voltage conversion). This wide voltage range makes the shaver suitable for international travel without needing a voltage converter.
- Power Consumption: Approximately 7W.
- Charging Time: 8 Hours for a full charge.
- Shaves per Charge: Approximately 7 times (based on 3 minutes per shave). This indicates a decent battery life for regular use.
- Measurement (H x W x D): 12.4 x 5.7 x 3.5 cm. This compact size suggests portability and ease of handling.
- Weight: 140g. This lightweight design further enhances its portability and comfort during use.
- Battery Type: NI-CD (Nickel-Cadmium) rechargeable battery (WES4853L2508).
- Motor: DC Motor (WES4853L1007).
Usage Features:
The shaver is designed for ease of use with a straightforward operation. It features a simple ON/OFF switch for controlling the motor. The "WASHABLE" designation implies that the shaver head and possibly the entire unit can be rinsed under water for cleaning, enhancing hygiene and convenience. The inclusion of a trimmer (WES4853K1507/S1508) allows for versatile grooming, enabling users to trim longer hairs before shaving or to style sideburns and moustaches. The automatic voltage conversion feature (AC 100-240V) is a significant convenience for users who travel internationally, eliminating the need for separate voltage converters. The device comes with a soft case (WES7025K7007) for storage and travel, and a cleaning brush (WES861B7056) for maintenance. Different charging adaptors are available depending on the region (C-2 PLUG, KS PLUG, A-2 PLUG), ensuring compatibility with local power outlets.
Maintenance Features:
The manual provides detailed instructions for disassembly and assembly, crucial for servicing and replacing parts. Key maintenance aspects include:
- Cleaning: The "WASHABLE" feature suggests the shaver can be easily cleaned by rinsing. A cleaning brush is also supplied for dry cleaning of hair clippings.
- Troubleshooting: A dedicated section helps diagnose common issues such as the motor not rotating, failure to charge, or excessive noise. It guides technicians through checks for the charging adaptor, rechargeable battery, module, and motor.
- Part Replacement: The manual includes an exploded view and a comprehensive replacement parts list, identifying critical components marked with a triangle (A) that are important for safety and must be replaced with manufacturer's specified parts. These include the protective cap, outer foil, inner blade, foil frame, trimmer driving bar, screws, O-rings, waterproof rubber, housing components, driving heads, DC motor, motor mounting base, module, bottom cover, tapping screws, trimmer, foil frame release buttons, rechargeable battery, switch cam, and body block.
- Solder Type: A warning is issued regarding Pb-free solder, noting its higher melting point and the need for temperature-controlled soldering irons (750 ± 20°F / 400 ± 10°C) to prevent damage or splashing.
- Specific Checks: The troubleshooting guide details checks for battery voltage (should be >1.2V DC), charging current (approximately 1000±150mA), and physical deformations of the outer foil or trimmer driving bar. It also emphasizes confirming the tightness of screws to prevent motor tremble.
- Waterproof Seal: During assembly, it's crucial to ensure no foreign substance sticks around parts covered with the waterproof seal to maintain the device's water resistance.
- O-ring Attachment: Proper attachment of the O-ring to the terminals is highlighted during module assembly to ensure a secure and waterproof connection.
Overall, the Panasonic ES4853 is a user-friendly and maintainable AC/rechargeable shaver, designed for convenience and durability, with comprehensive service information provided for professional repair.
