Maintenance Tips

For the Mower:

• Clean After Each Use: After mowing, clean the deck, blade, and wheels to remove grass clippings, dirt, and debris. Use a damp cloth or a soft brush, but avoid spraying water directly onto the motor or electrical components.
• Battery Care: Charge both the 4.0Ah and 2.0Ah batteries fully before storing them. Avoid exposing the batteries to extreme temperatures and store them in a cool, dry place. Recharge batteries periodically during extended periods of non-use.
• Inspect & Sharpen Blade: Regularly check the blade for wear, dullness, or damage. If necessary, sharpen the blade or replace it to maintain efficient cutting.
• Tighten Fasteners: Periodically check all screws, nuts, and bolts on the mower, particularly around the blade, wheels, and handle. Tighten any loose components to ensure the mower stays secure and stable during operation.
• Lubricate Moving Parts: Apply a silicone-based lubricant to the wheels and other moving parts to prevent rust and ensure smooth movement, especially on the self-propelled system.
• Clean Air Vents: Inspect and clear any grass or debris from the motor vents to prevent overheating and to maintain optimal performance.
• Height Adjustment: Ensure the height adjustment lever operates smoothly, and clean it regularly to avoid debris buildup that can affect its function.

For the Battery & Charger:

• Battery Storage: Always remove the batteries when storing the mower. Keep them in a cool, dry place away from extreme temperatures.
• Charging: Use the rapid charger to charge both the 4.0Ah and 2.0Ah batteries. Never leave batteries charging unattended, and unplug the charger once charging is complete.
• Battery Inspections: Periodically inspect the batteries for damage such as cracks, bulging, or corrosion. If any issues are found, replace the battery to prevent malfunction.
