How to Remove a Grass Trimmer Spool; The Grass Trimmer’s Mowing Head

Before beginning to change the filament, the brushcutter head should be separated from the machine and the filament spool should be inside it. This element is attached to the end of the stick of your grass trimmer and is removed by unscrewing it in the direction in which the arrow on the spool points.

After removing the mowing head with the spool, it must be opened. First of all it is necessary to find the catch mechanism on the spool. It is part of the spool and is like 2 clips, by pressing on which you can open the spool and get to the place where you want to wind the line for the trimmer.

Open the mowing head and take out the spool for winding the line

You can open it with your hands, or with screwdriver or other tools that will pry open the pawls.

Spooling the line

Filling the fishing line into the grass trimmer spool is a relatively simple procedure, provided that you follow a certain algorithm of actions. When you need to determine how many meters of consumable material is enough, wind it on the bobbin so that the coil does not exceed the diameter of the curbs. Once you have determined the length of the cord, follow these instructions:

  • Fold the consumable in half so that one end of the line is 10-15 cm longer than the other.
  • Charging should begin with the central edge, which divides the grass trimmer bobbin into 2 parts. Find the groove where you insert the cord. Bend the last end in half.
  • Determine which direction you want to wind the line for your trimmer. To do this, look closely at the bobbin, which may have an arrow or inscription on it. It indicates the side of the winding. If there are no markings on the spool, look at the arrow on the mowing head to wind it in the opposite direction.
  • Wash the consumable material carefully, coil to coil. Try to keep the thread as tight as possible.
  • When you have finished laying the cord, fasten the short end of the material first. To do this, insert it into the groove on the side of the spool, which will fit the diameter. The second end (longer), attach in the groove on the other side of the grass trimmer bobbin.
  • After securing the line to the trimmer, cut the ends. Do not forget to leave a seam allowance of about 10 cm.
  • Install the tucked spool to the mowing head of the unit. To do this, you must alternately insert and pull the thread into the output holes of the head to then place the device’s bobbin into the skin.
  • Applying the required force, pull the cord out of the fixing grooves and tighten the material. When you have finished, put on the cover and secure it with the latches.

You can also wind the cord onto the grass trimmer in another way, which charges two strips of material instead of one. Replace as follows:

Next comes the disassembly of the nozzle. There, the cover is attached by latches from the hole. So you just need to put these clips in the holes, and the cover will come off. If the nozzle has automatic / semi-automatic line feed modes, this means that there is a spring inside, which can simply fly out when you open the cover, be prepared for this. Lay out all the stripped pieces neatly in order.

Now it’s time to take the trimmer line and unscrew 5 meters of it, cut this piece. Pay attention to its thickness, do not screw on the knot of line for the trimmer of a greater thickness than indicated in the instructions for the tool. Otherwise, there will be an increased load on the engine and greater fuel consumption during operation. Bend the measured trimmer line in half to find the middle and get a loop.

There are several notches in the middle of the spool, sometimes these are not notches, but holes opposite each other. With the loop, we hook on one of the forks and wind the line for the trimmer counterclockwise. If there are 2 compartments in the spool, wind each end of the line on them separately. Leave 15 to 20 cm of free space and clamp it in the recesses of the coil.

We reassemble the device, pulling the loose ends of the fishing line into the holes on the body. Put the cover on, sliding the sliders into the grooves. Now you can remove those puffy ends of the mowing line.

It remains only to attach the working unit in place, as in the first point. Don’t forget to rotate backwards when winding.
