Atlas Copco PHE 6 H - User Manual

This document provides repair instructions for the Atlas Copco PHE 6 H and PHE 6 S electric power tools. It details the disassembly, maintenance, and assembly procedures for various components of these devices.

Function Description:

The Atlas Copco PHE 6 H and PHE 6 S appear to be rotary hammer drills, designed for heavy-duty drilling and chiseling applications. The presence of components like a spindle sleeve, anvil, piston, connecting rod, bevel gear, and a rotary stop indicates their capability for both rotary and impact functions. The "tool reception" sections suggest a system for quickly attaching and detaching various drill bits or chisels. The "carbon brushes" and "armature" sections point to an electric motor as the power source, typical for professional-grade power tools. The "crankshaft" and "reduction gear shaft" are integral to converting the motor's rotational energy into the necessary force for drilling and hammering.

Important Technical Specifications:

While specific numerical specifications like motor power or impact energy are not explicitly listed in the provided pages, the detailed repair instructions imply a robust and complex mechanical design. The mention of specific Torx screwdriver sizes (TX 30), socket wrench sizes (SW 50), and torque values (e.g., 120.0 Nm for the nut PHE 6 S, 30.0 Nm for the driver PHE 6 H, 2.5 Nm for screws in plastic, 4.0 Nm for screws in metal, and 3 Nm for the clutch) highlight the precision required for assembly and maintenance, suggesting a high-performance tool. The lubrication plan specifies "Red grease (80 g) Mobil SHC 007" and "Blue grease (80 g) Mobil HP 22," indicating the types and quantities of lubricants essential for optimal operation and longevity. The instruction to use a 32 mm nut for the clutch (6) further specifies a tool requirement.

Usage Features:

The design suggests features for user convenience and safety. The "auxiliary handle" (G/C) indicates a two-handed operation for better control and stability during use. The "dust guard cap" (3) on the PHE 6 H and "rubber cover" (2) on the PHE 6 S suggest protection against dust and debris, which is crucial in construction environments. The "switch lever" (C) and "retaining strap" (A) for tool reception imply a quick-change system for accessories. The "rotary stop" feature, detailed in the disassembly and mounting sections for PHE 6 S, suggests the ability to switch between rotary drilling and hammer-only modes, enhancing versatility. The "damping element" (2) in the handgrip implies vibration reduction for user comfort during prolonged operation.

Maintenance Features:

The manual is primarily a maintenance guide, offering comprehensive instructions for servicing the tool.

• Special Tools Required: A list of specific tools, including a Torx screwdriver TX 30, forcing disks, an adjustment tool for carbon brushes, a pulling-off device, and a tool for dis-/assembly of the spindle, is provided, emphasizing the need for specialized equipment for proper maintenance.
• Pre-Maintenance Checks: Before any repair, an initial check with a high voltage test according to VDE standards and a connection to the RTR-READER (maintenance measuring instrument) are required to assess the maintenance interval and electrical safety.
• Safety Precautions: The critical instruction to "pull the power plug from the socket" before any repair work highlights safety as a top priority.
• Cleaning: Detailed cleaning instructions specify using a "cold cleaning agent" for mechanical parts (excluding electrical components) and a "dry brush" for electrical parts, with a caution against cleaning agents penetrating bearings.
• Wear Check: Users are instructed to "check the disassembled parts for wear (visual inspection) and replace worn parts," indicating a proactive approach to prevent failures.
• Electrical Tests: Before reassembly, an "electrical test on all relevant parts" is mandated, ensuring the electrical integrity of the tool.
• Lubrication Plan: A thorough lubrication plan is provided, specifying where to "generously" apply, "fill," or apply a "small amount" of specific greases (Mobil SHC 007 and Mobil HP 22) to various components after complete disassembly and removal of old grease. This is crucial for the tool's performance and lifespan.
• Torque Specifications: Precise torque values for screws and nuts are given, ensuring correct assembly and preventing damage or loosening of components.
• Run-in Procedure: After assembly, a "test run" is recommended to check for noises, followed by a "run-in" period, which is important for the proper seating and functioning of newly assembled parts.
• Component-Specific Instructions: The manual provides step-by-step instructions for detaching and mounting various parts, such as carbon brushes, handgrip, armature, spindle sleeve, bevel gear, pinion shaft, crankshaft, piston, and connecting rod, ensuring a systematic approach to repair. This includes warnings about left-handed threads (e.g., nosepiece PHE 6 S) and specific orientations for parts (e.g., locking ring relief, cup spring bulging).
