Excuse me, but who is this understood by professionals?
Professionals without quotes are people who have undergone training and competently operate the equipment.
Summer resident I wrote.
Discharge gas is necessary only when moving from one mowing area to another. When MAKING, it is not necessary, why does the engine change loads?

the need to change speed when the trimmer moves. What for?
To these questions, at one time, there was a detailed answer from Husqvarna:
1) Gas discharge is useful, firstly, because the engine is slightly cooled, and secondly, the cylinder-piston group is better lubricated (this is especially true for mowing the disk, since the disk continues to rotate and rotate the engine by inertia). the throttle valve closes, enriched fuel flows through the idle channel, and more oil enters the parts of the cylinder-piston group.
2) Gas discharge is necessary if you have an idle passage. for example, when folding grass in rolls: to the left. mow, throw grass, dropping gas, lead to the right, increase gas, start mowing to the left.
3) In principle, you can mow without ever dropping gas (if there are no idle runs and the mower is constantly under load), but watch out for the following things. a) the fishing line can wear out, two short stumps will not give resistance to the engine, it will work at maximum speed and overheat; b) any engine can overheat if kept at maximum speed (Husqvarna designers did not set themselves the task of getting into the Guinness Book of Records for the maximum time before killing the lawn mower at maximum speed), so it is better to dump gas.
mows and fishing line and disc
What I quickly found on the Internet (for example, =.)) Is drawn with fishing line. I did not see anything about the disc.
spin at full power in reverse
And why just give full speed at any move? When you start to really work, the engine will clearly understand whether you need to add speed or not. Why do you need full speed when you have three blades of grass in front of you?
about variable loads, how much is not good for the engine
Remember how 2T motorcycle engines work. They do not work constantly at full speed. There will be nothing with a 2T engine from the change in speed.
the reverse motion doesn’t seem to be very convenient to mow, the grass scatters in different directions
When working with fishing line (this is exactly what I described), chopped pieces of grass scatter in all directions (including your trousers and shoes) in any direction of movement. That is why fishing line can be well aligned lawn. If you have a disk formed by a turning line, passes at the same distance from the ground, then with your duck forward movement over the treated area of the line, it passes 2, or even 3 times. This allows you to remove the stairs, other flaws. No need to hurry.
How to change the fishing line in the trimmer and which is better to choose
Since the choice of trimmer, we examined in a previous article. then today we will tell you how to properly trim the trimmer with fishing line, and which is better to choose based on the working conditions.
After you bought a trimmer and began to use it actively, sooner or later the question will arise about replacing the fishing line, since this is the most wearing element in the tool, then intensive use of the trimmer will lead to frequent replacement of consumables.
What types of woods are
The most common type of fishing line that fits almost all types of reels # 8212; cord of round section. This is an ordinary fishing line suitable for mowing juicy grass, but it will be much more difficult to mow dead wood with it, and even more so it can’t cope with the bush.
As a rule, the diameter by which young grass can be mowed does not exceed 1.6 mm. The thicker the thread, the more coarse grass it can overcome.
Important! Choosing a fishing line for the trimmer must be guided by the instructions for your tool, since a thin thread will increase the wear of the twisting mechanism, and a thick one will overload the engine.
There are fishing lines with sharp edges in the form of an asterisk or square, this option is more suitable for mowing dry grass just due to the existing sharp edges, but its drawback is more wear and tear and is inferior in strength to round cord.
There are fishing lines with improved aerodynamics with characteristic dents, scales and notches, such a product produces less noise, but they are used only on lawn mowers, since the exit of such a thread from the reel is difficult, it is used most often with discs in which segments are inserted. The disadvantage of this product is its fragility.
Most often in gas trimmers with an engine power of more than 1.5 hp apply cords with a metal cable inside. This thread is ideal for mowing dry grass and small bushes. The presence of a core positively affects the wear resistance of this material. The disadvantage of such a cord is its price, which is significantly higher than the listed opponents.
How to Fill a Fishing Line into a Trimmer Coil
It takes about 10-15 minutes to wind the line. What is a trimmer coil? Plastic case with a cassette inside, on which there is a special hook for convenient winding of fishing line. Almost all the coils of the trimmers have a similar principle of fastening, this is the central screw-button, when pressed, it becomes possible to pull the fishing line of the required length. The photo below shows some examples of different coils for trimmers.

The bobbins of trimmers, the motor of which is located near the ground, have a different mount to the axis of rotation, they have two buttons on the spool located on the sides that need to be pressed, otherwise the replacement of the thread is no different from other cassettes.
The principle of proper winding of the fishing line is similar in all of the above cases, so for example, consider the standard version with two antennae.
To remove the reel with fishing line, it is necessary to unscrew the screw located in the center, but note that the thread there is left, so you have to turn it clockwise, this is done specially so that during operation it does not open under the influence of centrifugal force.
Next, using a screwdriver, disassemble the head and take out the reel, on which the fishing line is directly wound. Having measured the necessary length and folded in half, you need to fill the fishing line into the reel, removing, in the end, its ends opposite each other (for this there are special slots for fixing).
After that, it is necessary to assemble the head in the reverse order by threading the ends of the cord into two corresponding holes.
If you have doubts or it’s not entirely clear how to charge the fishing line to the trimmer, we recommend watching the video: how to wind the fishing line into the lawn mowing properly. In this video, the instructor will open the trimmer head in steps, measure out the required amount of fishing line, usually from two to four meters, and demonstrate assembly and installation on the trimmer.

How to refill a fishing line in a trimmer so that working with it does not tire
Many summer residents use a trimmer. a scythe with an electric or gas engine to control weeds. It is convenient when working in places inaccessible to the lawn mower: at fences, flower beds, houses, in the garden on narrow aisles, and can cut small branches. The main element of this wonderful technique is an ordinary fishing line wound on a reel. The device is simple, but the cutting part wears out quickly, requires replacement. And the question of how to fill the line in the trimmer worries many owners of cottages.
Briefly about the fishing line
Depending on the models of the tool, the thickness of the fishing line is 1.2-4 mm. There are such configurations:
- round. the most durable;
- curly. for soft grass;
- twisted or notched. for thin grass;
- professional, not suitable for all instrument models.
When replacing the cutting thread, you need to choose the one that suits your type of trimmer. Preference should be given to specialized. Before filling the fishing line into the trimmer coil, it is better to soak it for half an hour in water. Then it will become more elastic and stronger.
How to quickly remove a coil from a tool
Before the thread is wound on a bobbin, it must be removed. over, the removal methods depend on the features of the tool. On trimmers with a motor near the ground, the spool has two side buttons, when pressed, a part of the housing is separated along with a thread winder.
On instruments with a bent rod, the lamb on the fixture is moved counterclockwise; having disconnected it, they remove both the bobbin and the spring inside it. On trimmers with a direct bar, fix it with a screwdriver, rotate clockwise and remove. Then the device is disassembled either using latches, or by moving its parts in different directions. The spring is taken out of the coil.
Refueling the fishing line with a trimmer
The main question is how to wrap the fishing line on the trimmer coil, fixing it securely there?
In the case of a device with one antennae, up to four meters of fishing line is unwound, inserted into the hole inside it, fixing the fishing line, one of its ends and moved in the direction indicated by the arrow. The edge of the thread is fixed in the groove inside the bobbin so that when it is assembled, it does not unwind. If there is no groove, then this free end is fixed with a finger. Then the coil is assembled.
How to refill the trimmer coil if it has two antennae? In this case, check how many grooves are on it. one or two. In the first case, both antennae are sent to the common groove, if there are two, then each of them. in its own. 2-4 meters of thread are passed through the hole so that the free edges of the thread are the same length, and twist the bobbin in the direction of the arrow. The ends of the thread are inserted into the grooves or held with a finger, assemble the device and attach to the trimmer.
In a spool with two grooves, the same piece of thread is folded in the form of a loop, sent to the groove between them and the ends are wound at the same time. Then repeat the previous assembly. With semi-automatic winding, the bobbins act as follows. The fishing line is passed through the hole inside, its ends are fixed in the holes on the body, collect it and press the button. In this case, the thread is easily wound in the right direction.
It is important to remember that the cutting surface must be protected from solid objects so that it does not wear out. Otherwise, it will be necessary to constantly stop and, having removed the bobbin, replace the spent fishing line. Let your work be not tiring and bring joy!
