Proper maintenance not only ensures the stable performance of the Angle grinder but also significantly extends its service life and reduces the failure rate. The following are the key maintenance steps
1. Cleaning after daily use
• Remove dust and debris: Use a hard-bristled brush to clean the body and heat dissipation holes to prevent blockage and affect motor heat dissipation.
• Check the cables and plugs: Ensure there is no wear or exposed wires to prevent the risk of electric leakage.
2. Regular deep maintenance
• Lubricate bearings and gears: Every 50 to 100 hours of use, add an appropriate amount of special lubricating oil to reduce friction losses.
• Replace carbon brushes: When the tool’s power decreases or abnormal noises occur, inspect and replace worn carbon brushes (typically with a lifespan of 20 to 50 hours).
• Tighten screws and components: Regularly check whether the screws of components such as handles and protective covers are loose.
3. Storage precautions
• Dry environment: Store in a place free from moisture to prevent the motor or circuit from getting damp and rusting.
• Classified storage of accessories: Fragile accessories such as grinding wheels should be stored separately to prevent breakage due to collision.
Through scientific maintenance habits, Angle grinders can maintain an efficient and safe working state for a long time, becoming reliable operation partners for users.
