How to put string on my B=D grass trimmer - Black & Decker String Trimmer Cordless 12" 18V

the size of the string is critical in electric driven trimmers
it does have mass and the thicker string will over load the motor
stay with the recommended string size and keep to the recommended distance to the grass being cut
string line cutters work on the principle that the tip speed of the string is what does the cutting and that means that the first 1/2" of string cuts the grass
the rest back to the hub acts like a brake as it is dragged across the grass and slows the cutting speed and loads the motor
remember that the machine is designed to trim edges and not to cut down growth-- that is a job for heavier duty units

No, it is not heavy duty enough to drive a blade. It should have cuttting line in it and it only can use up to .065" string (factory recommended).

To lengthen the string:

- Turn the Grass Hog upside down
- Push in on the two release buttons on either side of the spool (they're orange)
- Pull the spool head off and spin it to release more string while you pull the string with your hand (make sure it is still fed out through the hole in the base)
- Pop the spool head back into place

Test the Grass Hog to make sure the string is not too long. If it is you'll hear it cracking against the plastic guard on the base.

If the string is spinning it should cut no mater which way it is turning. maybe you aren't getting the trimmer close enough to the grass.

Wind the strings in the direction of the arrow on the spool.

Take your string trimmer reel and throw it in the garbage. Go get a gater head and put it on, it will be the best thing you ever did.

Did you re-string it? If you did it is possible that you crossed the string over itself and it is stuck. Check that and good luck...Lee

No, just the part that trims.

Cut two separate pieces of string, about 7 ft. each.

Stick the end of the line in the hole on the inside of spool.

Wind clockwise onto spool, putting the line that is closest to the ground on first.

Once you have winded this piece on, lock the last 4 inches of line through the slits on spool.

Repeat process for second piece of line, locking the last 4 inches in slot opposite the other locked in piece.

Put the spool on the trimmer, feeding the end of lines through either hole on trimmer.

Before you push the spool all the way on, pull the strings out of the locked position.

first of all be carefull of what you hit with the trimmer string if you hit sidewalks and rocks or dirt it will cut it short also you might make sure the tensil strength is strong enough to withstand the abuse the trimmers being subjected to :-)
