20 Most Recent Black & Decker String Trimmer Cordless 12" 18V Questions & Answers

These are the steps to open the clamshell/motor housing for the Black and Decker 18V Cordless Trimmer Model NST2018. The orange clamshell has two plastic clips that engage two recesses inside the black plastic ring. You use two screwdrivers to disengage the clips and seperate the black plastic ring from the orange clamshell. Follow these steps: Wrap tube assembly in a small towel and mount in a large bench vice securely. You will notice two small openings at the top of the black plastic ring at the top of the orange clamshell. The next steps require two people. Person one inserts a flat-bladed screwdriver into into each of the small openings at the top of the black plastic ring (two screwdrivers). Using the tube assembly for leverage, pry the black plastic ring from the orange clamshell with enough force to disengage the orange plastic clips from the black plastic ring. Person two pulls the orange clamshell/motor housing away from the black plastic ring/tube assembly along a straight line (same axis as the tube assembly). After you've separated the motor/clamshell housing from the black plastic ring, remove the six screws and open the clamshells.

Did you ever get an answer to this problem? I'd like to know because I have the same problem with my cordless 14" Black N Decker Gass Hog. I rethread it, but the line continually feeds and is out in about 2 minutes.

battery is probably dead... it may read fully charged but it cannot support the "load"... if you're only going to use something of that nature once. you really don't need it.

Sorry, but I haven't solved any problem. I'm still waiting on the experts to solve my problem from June 16 on my trimmer not operating even with new fully charged battery. As for your replacement, I would suggest retail stores that sell trimmers, such as Home Depot, Lowes, Ace hardware stores or maybe B&D website.

If you're talking about the line reel, Grip it with water pump pliers and pull. The springs are strong. Just push the new reel back on.

This could be a lot of things. One thing to check is the vents on the head. IF they are clogged then it over heats. Another thing is the battery connections and temperature. When it fails take the battery out if you can and see if it is hot.
