How to change blade?

Still worry about how to change your blade? That’s ok! MORI heard your voices; we’ll teach everyone how to change blade (brush cutter) in this article.

First, before change blades, we must be familiar with our structure of the nose, it can be roughly divided into five parts

1)Front head

2)Upper blade pressure block 

3)Lower blade pressure block 

4)Safety cover 

5)Nut

Since the axis of the machine head is free to rotate, Therefore, the axis must be fixed to lock the blade and other parts into front head. We can see a hole in the front head and upper blade pressure block has a groove design. The most important step is that we must insert the 4MM L-shaped wrench into the hole to fix the blade briquette and remember finish this step to continue the following installation!
