Maintenance Tips 

• Clean the Grinding Head: After each use, clean the grinding head to remove concrete dust, slurry, or debris. Inspect the grinding discs for wear and replace them when they no longer provide effective grinding.
• Check Engine Oil (Gas Version): For the gas-powered model, regularly check the engine oil level and condition. Change the oil as recommended in the user manual to maintain optimal engine performance.
• Inspect Electric Components (Electric Version): For the electric version, inspect the motor and power cords for signs of wear or damage. Replace any frayed or exposed wires to ensure safety and proper function.
• Lubricate Moving Parts: Lubricate the gearbox, bearings, and other moving parts to reduce friction and wear. Ensure smooth operation by applying grease to these components regularly.
• Inspect and Replace Drive Belts: Check the drive belts for cracks or wear. Replace them as needed to prevent disruptions in operation and maintain consistent grinding speed.
• Check Safety Features: Ensure that all safety features, such as emergency stop switches and safety guards, are functioning properly. Inspect the handle and base for stability and secure any loose parts.
• Monitor Fuel or Power Supply: For gas models, ensure the fuel tank is filled with fresh fuel and the system is free of any leaks. For electric models, ensure the power source and extension cords are properly rated and in good condition.
• Examine Dust Collection System: Check and clean the dust collection system regularly. Replace filters if they are clogged to ensure proper dust extraction and a cleaner work environment.
• Inspect the Base and Wheels: Check the base and wheels for signs of damage, wear, or misalignment. Ensure they are properly aligned and secure to maintain stability during operation.
• Store Properly: When not in use, store the grinder in a dry, safe location to prevent rust or damage from exposure to moisture and other environmental elements.
• Annual Professional Inspection: Schedule an annual inspection by a professional technician to ensure the engine (gas model), motor (electric model), and mechanical components are in good working condition
