Question about Black & Decker String Trimmer Cordless 12" 18V

1 Answer

ST 4000 corded

The line keeps coming out too far while I'm using the trimmer. It starts hitting the side of the trimmer head and broke some off. I checked for correct line size, and it is right. Can you tell me what the problem might be?

Could be the spring, could be not setting right in the spool causeing the spindle to think its being pushed down when its not. causeing it to spit out the line.

check that and if you have another spool kicking around please grab that as well for testing the unit. could also be the spool itself try cleaning that out as well if it looks too dirty.

Replace trimmer line


The steps for replacing line in a single line trimmer head are virtually the same for many trimmer head types, like double line trimmer heads.
1. Remove the Trimmer Head Spool
Removing the spool is the first step in replacing trimmer line in any conventional trimmer head, but trimmer head spools can disassemble in different ways.
The trimmer head pictured above and below disassembles by simply unscrewing the knob around its arbor bolt. Other trimmer heads can use press tab and other twisting styles for disassembly.
2. Insert Trimmer Line and Wind the Line
Single line trimmer heads have just one channel in their spools for winding line. The channel will have a hole in it somewhere that keeps the line in place as it is wound around the spool. Insert one end of the trimmer line in the hole.
Depending on the trimmer head, it might be helpful to bend a small portion of the cutting line at an angle before inserting it in the starter hole. Also, cutting the line at an angle can help this first step on some trimmer heads.
Of course, it is also important to make sure that the replacement line matches the diameter specification of the trimmer head before beginning. Once the line is started correctly in the channel hole, you're ready to wind. Most trimmer heads will indicated the correct winding direction right on the spool somewhere.
It's also important to wind the line carefully, keeping it in neat rows as much as possible. The line will have a much higher chance to feed incorrectly during trimmer use if it suffers from sloppy winding.
3. Snap the Line into its Retaining Notch
A conventional trimmer head will have a retainer on its spool. Snap the end of the trimmer line into the retainer after it is wound around the spool. The retainer will hold the line in place as the spool is replaced in the trimmer head assembly.
4. Replace the Trimmer Head Spool
With the cutting line held in place, the spool is ready to be replaced in the trimmer head assembly.
First feed the extra trimmer line through the trimmer head eyelet. Make sure to release the line from the retainer before completely securing the spool into position.
Replace any knobs, bolts, or other trimmer head pieces removed during disassembly.
Your single line trimmer line is now reloaded, and your trimmer should be ready to get back to work.
Although there are many steps to reloading line the conventional way, a little practice and familiarity with your trimmer will speed the process up a great deal. Once you're up to speed, reloading trimmer line this way can take less than five minutes.

How to replace trimmer line ?


1. Remove the cap on the trimmer head, it unscrews.

2. The spool comes off, and on the inside of the spool there is a small hole, this is where you will start your trimmer line. It it will hold it in place while you wrap it. There is also arrows on the spool showing the direction that you need to wrap your spool.

3. Insert the line in the hole and start to wrap the line in the directions of the arrows, try to keep the line in rows, or else the line may bind and you will have to do it all over again.

4. Feed the line through the retainer and reinstall the spool by lining up the retainer and the slot on the outside portion on the trimmer head, the screw back on the trimmer head and you will be ready to trim.

How do i replace the nylon cord on stihl fse 60 trimmer pg 19 of the manual says to consult the chapter on how to replace the cord, but no such chapter exists


* NO DISASSEMBLY REQUIRED(DON'T TAKE HEAD APART!)*
First make sure the arrows on the head are aligned and the bump head is securely tightened(clockwise). Take a minimum of 20 feet of line from the package and cut it evenly so you have two pieces of equal length. Next insert one end of each piece into the holes on the trimmer head until they are seated firmly(some minor twisting of the head may be required to get the line in more than an inch or two). Once you have gotten a couple of inches into the trimmer head you should have everything still fully assembled with a long strand of line coming from each of the holes. Now begin turning the gear shaped part of the head in the direction of the arrow indicators and the line should begin winding itself inside the 'keeper'. Once the head doesn't turn freely or starts to slip it's full and you can cut off the remaining line, if any, and get to cutting.For more visit www.CollegiateSunglasses.com for safety glasses and other items.

Remove head to replace line


turn unit upside down so you are looking @ the underside of the spool. On the side of the spool should be a hole which you insert a rod to keep the spool housing from turning on the shaft. Turn and head will come right off.
