I went to the B&D web site and downloaded the manual for this unit.

no fuse in this unit. checked first the switch terminal then the motor connetion. could be brushes.

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.

the cord release is stuck in the open position release it and use a lubricant to get it to slip easily

stick it in the center hole an wrap in the direction thats printed arrow on plastic till its almost full

Faulty switch?

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.
