Operating Instructions

Follow these steps to safely and effectively sharpen your lawnmower blades:

1. Blade Preparation: Before sharpening, clean the mower blade thoroughly to remove any dried grass, dirt, or debris. This prevents imbalance and ensures a clean sharpening surface.
2. Safety Gear: Put on your safety glasses and ear protection.
3. Power On: Turn on the sharpener using the power switch. The grinding stone will begin to rotate.
4. Blade Positioning: Hold the mower blade firmly and carefully insert it into the sharpening slot, resting it against the blade guides. The guides are designed to maintain the correct sharpening angle.
5. Sharpening: Apply gentle, consistent pressure, moving the blade slowly across the grinding stone. Sharpen one side of the blade until a new, sharp edge is achieved. Use the reversible switch to sharpen in both directions as needed.
6. Repeat for Other Side: Flip the blade and repeat the sharpening process on the other cutting edge.
7. Blade Balancing: After sharpening, it is crucial to balance the blade. An unbalanced blade can cause excessive vibration in your mower, leading to premature wear and potential damage. Use a blade balancer (not included) to check and correct the balance. Remove small amounts of metal from the heavier side until the blade is perfectly balanced.
8. Power Off: Once sharpening and balancing are complete, turn off the sharpener and unplug it.
