How To Change Your String On A Stihl String Trimmer Bump Feed

Threading the line into the trimmer spool

STIHL AutoCut 25-2 mowing head step-by-step

Open the mowing head by pressing on the side of the recesses in it. First press one side inward enough to disengage the catch, and then press the other. Then remove the cover of the mowing head.

It is worth a little torment, and the power of Hercules will not help you. Only with time do you understand how to quickly disassemble it.
If you have a Chinese head, it will be a little easier to disassemble (plastic is thin).
There are also the words “Push and twist” in translation “press and turn”

After you remove the top cover, you need to get the cord holder, while doing this, be careful not to lose the spring.

Take two strings (about 2 meters each). Insert the end of one string into one of the spool ears and wind the string in the direction shown. Make sure that the string is evenly distributed and wound tightly. Thread the end of the string into one of the holes in the reel.

In case of a Chinese head Measure the required amount of line (4-5 meters) and fold it in half.
Place the folded line in the middle over the holder (there is a special slot in it) and start winding the cord so that each mustache of the two falls into its own compartment of the holder.

Insert the spool into the mowing head. Pull the ends of the string out of the holes of the reel and thread them into the special groove of the mowing head

And here you perfectly understand that buying a fishing line with a diameter of 3 mm was your mistake. Generally the recommended STIHL reel diameter is 2.4 mm

But if you have a Chinese head. This rule doesn’t concern you. Some buyers said that they even managed to shove 4 mm. True coil breaks fast.

Pull the whiskers out through the eyes and install the top head cover, aligning the side latches.

In the course for STIHL equipment sellers, we were told that in order to increase efficiency, it is necessary to throw the reel of line into the water for 20 minutes. I haven’t tried it myself, but I think these guys won’t cheat.

Coil with two working tendrils

In this type of spool, you should determine the number of grooves for winding the line, lying on the inside of the spool:

  • one groove. both antennae are wound together in one groove;
  • two grooves. each antenna is wound on an individual groove.

For both cases, a line with a length of 2-3 m is taken.In single-groove reels, the line is pulled into a through hole, its ends (antennae) are folded together and aligned, after which they are wound in the opposite direction of rotation of the bobbin on the rod side. inside the arrow usually indicates the correct direction of winding. If there are fixing grooves, the ends of the fishing line are threaded through them or held with the fingers of the free hand, they are threaded into the through hole of the outer half of the bobbin, the spool is closed and attached to the trimmer bar.

The difference in line winding in double-groove spools is that initially a 2-5 m long line segment is folded in half (to determine the middle fold), and the fold loop is inserted into a special groove between the grooves. Both antennae of the fishing line are wound each along its own groove, fixing the antennae and assembling the coil is similar to the above option with one groove.

The first execution of this procedure, perhaps, will seem long and rather laborious, but with time and experience this task will be solved much faster and easier.

The video below will clearly show how to thread the line into the trimmer spool and wind it correctly. this operation is not difficult and with some patience it will certainly be crowned with success:

After the cutting thread has worn out as a result of the work, turn off the scythe and remove the cover on the mowing head. Pull the wood out of the slot by pulling it to the desired length, and reinsert it into the slots. The amount of material wound on a reel is enough for 5-10 work cycles, depending on the model of the device. When you put the cover back in place, carefully look if the grooves where the latches are inserted are not clogged, if they are clogged, then thoroughly clean them.

When the line is worn out, you need to disassemble the mowing head again, remove the spool and rewind the line on it.

The trimmer is the most common machine used for cutting grass and small bushes. This device is distinguished by its simplicity in service, simple operation during operation, and due to its low weight, even women can cope with it. It is no secret that for high-quality performance of work on mowing grass, the correct selection of cutting tools is required. As the latter, special cutting attachments (discs, knives) or trimmer heads with a fishing line inside are used in trimmers. Nozzles and fishing line are consumable tools, but if the knives can be sharpened, then when the line is used up, it must be replaced. In this article, we will tell you in as much detail as possible how to properly replace the fishing line.

Preparation. remove and disassemble the spool

On most electric and petrol trims, you will need to remove the spool to replace the line. The FUBAG tool lets you skip this step. To make the instruction universal, we will still consider it in detail:

Lock the shaft. Insert the locking element into the corresponding hole. It can be a thin screwdriver or a metal rod.

Unscrew the bobbin case. In our example. strictly in the clockwise direction.

Unscrew the cap according to the direction indicated on the body.

Take out the coil for winding.

The preparatory stage has been passed. You can proceed to winding the fishing line.

Coil with one working tendril

The simplest option and uncomplicated sequence of actions:

screw, line, stihl, trimmer
  • The dimensions of the reel and the length of the original factory winding determine the recommended length of the line for winding. 2. 5 m.
  • One end of the line is inserted into the fixing technological hole located inside the spool.
  • The fishing line is wound on the drum in the opposite direction of the spool rotation on the trimmer product. as a rule, on the inside of the reel, an arrow indicates in which direction the winding is carried out.
  • A small section of the line is left free to bring it out. it is fixed in a specialized groove on the inner side of the bobbin, designed to hold the winding when assembling the bobbin into working condition.
  • The left end of the line is passed through the hole in the outer part of the reel.
  • The bobbin halves are assembled and put on the trimmer bar.

How to choose a fishing line. length, diameter, restrictions

Any electric or petrol trimmer can be used with different brands of line. However, the best option is a consumable of the same brand as the tool. It is believed that in this case it will benefit the durability of the work and even reduce the cost.

screw, line, stihl, trimmer

IMPORTANT TO REMEMBER! Do not use fishing line or metal cables for the trimmer. This replacement is ineffective and dangerous. The rope can injure not only the mower himself, but also those around him.

As for the length, you should rely on the estimated frequency of use of the trimmer. The more often, the more it costs to stock up expenses.
See the trimmer reel body for the possible line diameter. Most likely, the range will be indicated there. The thickness varies from 1.2 to 4 mm. Choose the appropriate option, taking into account the characteristics of the cultivated area. The larger the diameter, the easier it is to mow tough grass.

How to tuck the line into the trimmer reel calm

How to wind the line onto the trimmer spool

First, determine the length of the consumable for your spool. Twist the line onto the bobbin until it steps over the sides. We got 4 meters. How much you get depends on the diameter of the line for the spool and the design features.

What is needed to replace the cord

With regular use of the grass trimmer, the discs become dull, but they can be sharpened and continued to operate. The line in the reel tends to end, so it becomes necessary to refuel a new one, for which it is necessary to determine the type of head and prepare the cord of the required thickness and length.

So, the mowing head is a cylindrical body in which a bobbin with a fishing line is placed. Such a detail is present both on electric trimmers and on gasoline scythes of any brands, be it Bosch, Makita, Stihl or another brand. There are three types of heads depending on the method of threading and feeding the line.

  • The principle of operation of the heads of the automatic group is that they independently feed the line when the mower reduces the engine speed. Such designs are convenient when working on large areas, but they have a drawback. high cord consumption.
  • The heads of the semi-automatic group are easy to operate. automatic line feed is performed at maximum engine speed. To release the lanyard blockage, gently tap the tool on the ground and the unlocked thread is pulled out of the spool. Cutting to the required length is made with a knife attached to the protective cover.
  • Trimmers with manual cord feed must first be turned off, then pull out the line yourself.

On a note! The most convenient and optimal for the price are semi-automatic reels with cord.

Reels for electric and gasoline braids can be with one or two line tendrils. The former are used for trimming low grass growth, the latter for mowing tall grass and small shrubs.

ATTENTION! Typical line problems

No wonder they say: “Forewarned is forearmed
“. Knowing about possible problems and the causes of their occurrence, you can prevent them in time. We recommend to remember or leave a memo.

Problem Cause Decision
Line break Stones, branches and solid objects in the grass Avoid collision
Poor cord quality Replace with a quality analogue
Head outlet wear Complete replacement of part required
The line is unwound The spring in the coil is weakened Check spring and replace if damaged
The line is sticking Poor line quality, due to which it can melt under the influence of temperature from the heating head Reel in less line or replace with a better line

Learning to properly wind the line on the trimmer reel and petrol cutters installation instructions

A gasoline or electric trimmer is an indispensable tool in the arsenal of a modern summer resident or owner of his own home.

Thanks to these garden tools, even a large garden plot can be mowed with ease. After purchasing this tool and performing several mows, many people think about how to properly wind the line on the trimmer reel. For an inexperienced user, the first operation to replace it will seem problematic and time-consuming, since the developers often do not fully reflect the instructions for replacing the fishing line in the operating manual.

Spool Trimmer Heads

The main elements of the trigger is the mowing head, which is a cylindrical body with a bobbin inserted inside. The fishing line (cord) is tucked into it. The heads differ from each other in the way of feeding and threading the cord. There are three types of heads in total:

  • Automatic. The line is then fed as the user decreases the engine speed. Automatic cord feeding is very convenient when there is a lot of work to be done. The disadvantage of such a head is the high thread consumption.
  • Semi-automatic. The use of such a head does not require the user to perform any complex manipulations. The principle of its operation is designed in such a way that the line begins to automatically lengthen while the trimmer is operating at full speed. You just need to lightly bang the head of the machine on the ground (this will remove the blocking of the line), and the cord will be pulled out of the bobbin due to centrifugal force. Then the line is cut to the required length with a knife, which is located on the protective cover.
  • Manual. To lengthen the cord, it is necessary to stop the apparatus. After that, the line will need to be pulled out manually.

Instructions with a step-by-step description of how to wind the trimmer coil and petrol cutters

In order not to be mistaken with the choice of a suitable fishing line for your tool, you should first disassemble the head and look at the side wall of the reel. This information is usually presented on a tip, which will not allow you to make mistakes with the use of the appropriate equipment.

If there is information on the reel about the diameter of the line you can fill in, then this information can be clarified in the instructions. Having decided on the thickness or diameter of the rig, it remains to figure out how to charge it. There are two ways to do this, but not all of them are applicable. We will consider both methods in detail, and depending on which models of brushcutters and trimmers you use, you decide on your own which option is suitable.

It is interesting!
The principle of how to wind the line to guide brushcutters is appropriate not only for autonomous gasoline units, but also for electric trimmers.

Method 2. how to properly put the line on the reel of the brushcutter with photo description and video

The second method differs from the first in that it is not a single piece of equipment that is charged into the coil, but segments from two parts. This method is used by manufacturers, and it is also suitable for those who have leftover material. The principle of how to insert two lengths of line into the brushcutter is the same as with the first method, and to make sure of this, below are detailed instructions:

    There are two equal length pieces of material that you can use.

One piece is taken, and the edge is bent in the form of a clamping bracket or hook, with which the fishing line will be fixed

Inside the coil there are holes in the form of a bracket for fixing, which are there for a reason. If they are not there, then the second option will not work. The appearance of these brackets is shown in the photo below. Each bracket is in its own half

The brace of the fishing line should be hooked on the bracket, and wind it in observing the direction of the arrow

  • The rig is wound until a 10-15 cm segment remains, which is fixed in the corresponding hole on the side of the guide
  • Manipulations with the second end of the fishing line are carried out in the same way.
  • The protrusions are inserted into the holes of the head, and then, removing the equipment from the temporary fasteners in the reel, a cover with latches is installed
  • Stihl Trimmer Line Replacement

    The above instructions on how to install a fishing line in a brushcutter will help not only correctly, but also quickly make the replacement procedure. Assembling the trimmer coil, as mentioned above, can be done without removing the head, but in this case, you will need to conveniently fix the tool. Video instruction is presented below.

    What you need to know about trimmer line

    A fishing line is a consumable that is made of nylon and serves as a cutting device. By means of this equipment, the grass is cut, which is ensured by rotating the tool head at a high frequency. This material has a different thickness, which depends on its use on the corresponding tools, electric low-power (from 1 to 1.6 mm), electric from 500 W (2-2.4 mm) and gasoline trimmers with brushcutters (from 2.4 to 3. 2 mm).

    The more powerful the tool, the correspondingly thicker the cutting equipment should be. This affects not only the quality of the grass cut, but also the service life of the material. If you are wondering how to wind the trimmer coil, then it is time to change and recharge the tool. With the onset of spring, this question is becoming more and more popular, so it’s time to figure out the step-by-step instructions for replacing the line in the trimmer reel.

    How does the head with a fishing line work on a brushcutter why you need to know the principle of operation

    Depending on the manufacturer, the heads differ structurally not only externally, but also internally. Most drums have a pressure spring inside (semi-automatic and automatic). Above is an instruction on how to disassemble the trimmer head without a spring, i.e. on the head of the manual type. The principle of dismantling a semi-automatic head with a spring inside is almost identical to the instructions described above.

    The principle of operation of the semi-automatic trimmer coil is as follows:

    • Inside the head there is a coil, which is fitted on the slots, which prevent its free movement.
    • A spring acts on the coil, which presses it against the splines in the cover structure
    • A fishing line is wound on the tip, the length of which depends on the tool itself. Typically this length is between 1 and 4 meters.
    • During the performance of work, if it is necessary to increase the length of the line, the protruding part of the drum is pressed, whereby it disengages from the splines. In this case, the line is unwound from the drum, increasing in length
    • After releasing the required amount of fishing line, release the pressure and continue cutting the grass

    The advantage of a tool with a line is that this consumable does not require sharpening, compared to metal discs. In addition, if a stone or a tree comes across on the way, the line simply breaks off, without negatively affecting the gearbox and engine of the tool, as is the case with metal cutting discs.

    Knowing the design and device of the types of mowing or trimmer heads, it is necessary to go on to consider the process of threading the line into the trimmer spool. After all, it is this very moment that causes difficulties for most owners of special tools.

    Which line to choose to refuel the lawn mower

    The thickness of the polyethylene thread depends on the model of equipment and varies from 1.2 to 4 mm. She may be:

    • with a round cross section. this is the most durable material for mowing grassy plants;
    • with a curly section. used for mowing soft plants;
    • twisted. used for thin grass;
    • professional type, not suitable for all models of equipment.

    To change the line on a lawn mower, you need to purchase a cutting thread that will be ideal for the type of mower.

    Criterias of choice

    You can soak the thread in a bowl of water for a few minutes to increase elasticity and strength.
