My string/line cutter is not working or possibly the cutter is broken off. I can't tell, and can't find a picture of the original part. If I purchase your guard assembly #90560170N, is a string/ line cutter included in that part. In your diagram I can never see the underside of this part. Am I correct in assuming that there is no cutter only part available for this older model. TY

I can not get the old guard off, I removed the screw but no matter what I try the broken guard will not slide out/off.

asked on 2022-05-09
Hello Diane, Thank you for your inquiry. With the screw removed you will then have to use a flat blade screwdriver to push down on the 2 tabs and pull the guard off. I hope this helps and good luck with your repair.

For a Black n Decker cordless weed trimmer. The hood cover (guard assembly) over my cord reel was cracked and had to be replaced. The cap cover over the cord reel was completely worn out and had to be replaced. The hood only required a screwdriver and removing a couple of screws then pulling the old cracked cover off. Installing the new hood was as easy as sounding into position and then securing it with the screws. These inexpensive parts were easy to replace and saved me from purchasing a new weed trimmer.
