Atlas Copco PHE 16 RL-N - User Manual

This document provides repair instructions for the Atlas Copco PHE 16 RL-N and PHE 20 N electric power tools. It details the disassembly, maintenance, and assembly procedures for various components of the device.

Function Description

The Atlas Copco PHE 16 RL-N and PHE 20 N are electric power tools, likely hammer drills or rotary hammers, given the references to "hammer mechanism," "drill spindle," and "percussion body." These tools are designed for drilling and potentially hammering applications, indicated by the presence of a "hammer switch lever" and components related to a percussion mechanism. The "drill spindle" is the part that holds the drill bit, and the "wobble gear drive" and "reduction gear" suggest a robust transmission system for delivering power and torque. The "carbon brushes" and "armature" are typical components of an electric motor, indicating that these are electrically powered tools. The "gear box" houses the gears responsible for transmitting power and converting rotational motion.

Important Technical Specifications

While specific numerical technical specifications like power output, RPM, or impact rate are not explicitly stated in this repair manual, the document provides insights into the internal mechanics and precision required for the tool's operation. For instance, the "end play" of the wobble gear drive must be precisely 0.05 + 0.03 mm, highlighting the importance of tight tolerances for optimal performance and longevity. The "locating distance" for the sealing ring on the drill spindle is specified as 3.5 ± 0.2 mm, further emphasizing the need for accurate assembly. The document also mentions specific grease types and quantities for lubrication, such as "6 g Tivela" and "15 g Darina," which are critical for the smooth operation and wear prevention of moving parts. The drill bit size for removing the sealing ring is specified as 3 - 3.5 mm, indicating the scale of some internal components. The repair instructions are dated November 1995, suggesting the vintage of these particular models.

Usage Features

Based on the disassembly and assembly steps, the tool likely features a mechanism for easy drill bit changes, as indicated by the "nosepiece" and "sleeve" components on the drill spindle. The "hammer switch lever" suggests the ability to switch between different operating modes, such as drilling and hammer drilling, offering versatility for various tasks. The presence of a "housing" and "handle shells" indicates a design that encloses the internal components and provides a grip for the user. The "power supply lead" confirms it's a corded electric tool, requiring a connection to a power outlet. The "mounting cone" for the gear box and the various springs and discs suggest a robust and potentially adjustable mechanism for power delivery and impact. The "pillow block" and "cylinder" are integral to the percussion mechanism, implying effective impact delivery for demanding applications.

Maintenance Features

The manual is entirely dedicated to maintenance, emphasizing its importance for the tool's lifespan and performance. Key maintenance features include:

• Regular Maintenance Schedule: It is recommended to submit the tool for maintenance regularly, or as soon as the hammer mechanism weakens or carbon brushes switch off. This proactive approach helps prevent major failures.
• Comprehensive Disassembly and Assembly Instructions: The document provides detailed, step-by-step instructions with accompanying diagrams for disassembling, cleaning, and reassembling various sections of the tool, including the drill spindle, gear box, pillow block, wobble gear drive, bearing end plate, and handle shells.
• Component Replacement: During maintenance, all parts of the "maintenance set" must be exchanged, ensuring that worn components are replaced with new ones for optimal performance.
• Cleaning Procedures: Specific instructions are given for cleaning parts, including the use of "cold cleaning agent" for mechanical parts and a "dry brush" for electrical parts. A crucial caution is provided against cleaning agents penetrating bearings.
• Wear Inspection: Users are instructed to "check the disassembled parts for wear (visual inspection) and replace worn parts," highlighting the importance of thorough inspection.
• Lubrication Plan: A detailed lubrication plan is provided, specifying the types and quantities of grease (Tivela and Darina) and their application points (A, B, C) on various components. This is critical for reducing friction and extending the life of moving parts.
• Electrical and Mechanical Testing: Before reassembly and after maintenance, electrical tests are required on all relevant parts, and a "high voltage test" is specified according to VDE standards. A "Test Run" is also recommended to check the direction of rotation and let the machine run-in.
• Safety Precautions: The manual explicitly states, "Before all repair work, pull the power plug from the socket!" This emphasizes user safety during maintenance.
• Special Tools: The requirement for an "Assembly cone" is mentioned, indicating that specialized tools may be needed for certain maintenance tasks.

Overall, this manual provides a comprehensive guide for maintaining the Atlas Copco PHE 16 RL-N and PHE 20 N, ensuring their longevity and reliable operation through detailed repair and lubrication procedures.
