Product description Color: gold 30 replacement blades Application instructions 1. Please note that the blades are extremely sharp during assembly. 2. If the cut looks uneven and dirty, it's time to change the blades. Please always exchange any used knives for a new replacement blade! 3. We recommend replacing the screws directly when changing the blade. 4. Turning the blade does not make sense, because the direction of rotation of your robotic lawnmower usually changes. Feature: 1. [SMOOTH CUT]: Due to the thickness of 0.75mm and weight of 3g, the automatic trimmer replacement blades produce a smooth and even cut. Axle load is NOT affected by the slightly higher weight! 2. [LONG SERVICE LIFE]: The knife set is made of stainless steel, which ensures a long service life. The screws provided are also STAINLESS STEEL! 3. [HIGH SAFETY]: Auto motor robot replacement blades cannot break using high quality materials. Even if the blade encounters resistance (stones or similar) - ideal for the safety of animals and children! Sold by Briday Store
