Product Overview
The FLEX SE 125 18.0-EC is a high-performance cordless power tool designed for professional applications. This document provides a detailed exploded view of the internal components, facilitating accurate identification for repairs, maintenance, and part replacements. Understanding the assembly structure is essential for ensuring the longevity and optimal performance of the device.

Maintenance and Lubrication
Proper lubrication is critical for the smooth operation of the internal gear systems. The device features two primary gear assemblies that require specific maintenance attention:
- Planetary Gear: Requires 5g of specialized grease to ensure efficient power transmission and reduce wear on the planetary gear set.
- Angle Gear: Requires 20g of specialized grease to maintain the integrity of the angle gear mechanism under load.
Using the correct type and quantity of grease as specified is vital to prevent overheating and mechanical failure. Ensure that the housing is properly sealed after maintenance to prevent debris ingress.
Component Identification
The exploded view illustrates the precise arrangement of the motor housing, gear assemblies, and external casing components. Key parts include the main motor unit, the planetary gear carrier, the angle gear housing, and the protective covers. When performing repairs, ensure that all screws and seals are tightened to the manufacturer's specifications to maintain the tool's structural integrity and safety standards.
Safety and Handling
Always remove the battery pack before performing any maintenance, inspection, or part replacement to prevent accidental activation. Ensure the work area is clean and that all components are free from dust and debris before reassembly. If any parts show signs of excessive wear, deformation, or damage, they must be replaced with genuine FLEX spare parts to ensure safe operation.
Disposal
When the tool or its components reach the end of their service life, they should be disposed of in accordance with local environmental regulations. Do not dispose of electronic components or batteries in household waste. Utilize designated recycling centers for power tools and lithium-ion batteries to minimize environmental impact.
