Product Maintenance Tips:

1. Routine Inspection and Cleaning

• Periodically disassemble and clean the hammer after use. Use specialized tools to lightly tap during disassembly to avoid deformation of internal parts.

• Avoid forceful hammering, welding, or heating methods, as these can render the hammer unusable.

• Recommended tools include chain wrenches, small disassembly spanners, and tools that allow precise and gentle vibrations.

2. Internal Component Cleaning and Lubrication

• Use a cleaning agent to clean all internal parts thoroughly. Blow them dry with high-pressure air, apply an even coat of machine oil, and reassemble.

3. Part Inspection and Replacement

• Replace parts immediately if cracks, scoring, or damage occur, or if the splines on the front connector are worn by more than 60%.

4. Wear Measurement and Component Replacement

• If performance declines due to wear on the outer casing or internal components, use professional measuring tools to determine whether repairs or replacements are required.
