But given that there are many copies of less well-known brands in our markets, the described procedure may be suitable for owners of other portable garden equipment for lawn and grass care.

How to replace, remove the BlackDecker GL716 trimmer head

No matter how well the electric trimmer we purchased works in a summer cottage or a country house, sooner or later the time will come when we need to remove the trimmer head for replacement or prevention. I will make a reservation right away that you do not need to completely remove the trimmer head to replace the fishing line. As part of this article, I will tell you how to completely remove or replace the cutting head using the example of the BlackDecker GL716 electric trimmer.

How to remove the head on the trimmer BlackDecker GL716.

The trimmer has an overhead engine and curved boom. For convenience, we turn it over with the engine down or lay it horizontally. We disassemble the mowing head. To do this, simultaneously press on the side latches and remove the top cover. Disconnecting the line reel.

A slightly recessed dark screw is visible in the middle of the head body. We fix the head body with one hand and use an asterisk nozzle to unscrew the screw counterclockwise. If you don’t have a sprocket at hand, you can do this with a wide flat screwdriver.

Now, to remove the trimmer head, just pull it towards you. If it is sour and firmly in place, then add light swaying movements to the efforts, periodically changing the places of their application. Do not use force or shock. The case is plastic and it is easy enough to damage it.

Installing the mowing head to the trimmer is carried out in the reverse order. When installing the screw in place, it is tightened with medium force.

I wish you a successful summer cottage season and that the gardening equipment does not let you down. I hope my advice on how to remove the cutting head on the BlackDecker GL716 trimmer has saved you time and hassle.

Everything about changing the line on the trimmer head. How to change the line on a lawn mower: detailed instructions

In 1971, American entrepreneur George Bollas invented a lawn mower that used a line as a cutting knife. Much time has passed since then, the drive has become more powerful, a modern trimmer can easily damage the bark, so the idea itself has transformed into mowing grass around obstacles without damaging the mower cutterbar itself. For a neat cut around obstacles, a smaller line head can be used and is easy to change from large areas to delicate mows. However, the cutting tool itself needs to be replaced periodically. We will tell you how to disassemble the head of a lawn mower (trimmer) and reel in a new line.

Choosing a line for the trimmer head

There are many types of heads available to suit different types of line. The latter is also available in several diameters: from 1.0 mm to 3.2 mm. over, its cross-section is round (including with a special groove to reduce the noise level), square, twisted and in the shape of a star.

There are no clear preferences, this explains the wide variety of shapes and diameters on the market. The round shape is usually stronger, but has the worst cutting ability and also produces a characteristic sound when rotated. Therefore, sometimes an acoustic groove is made on it, however, the use of this line only makes sense on battery trimmers, in cars with a gasoline engine and a network drive, the sound level of the drive itself practically drowns out the sound from the line. The square has a good cutting ability, and despite the fact that such a line is less strong than a round line, on average it is consumed less. Square fishing line quite easily cuts off the growth of the same willow up to 1 cm in diameter. The star has the maximum number of cutting edges, mows the best and is consumed the fastest.

The next nuance when choosing is rigidity. The fact is that during the production of nylon, a modifier (often maleic anhydride) is added to it, which improves its strength and prevents tearing. However, modifiers are not the cheapest component, they are trying to save on it. Therefore, a seemingly good line, which remained for the winter, unexpectedly behaves in a completely different way in the spring. it breaks, stops coming out of the reel normally. There is a recommendation to soak the fishing line in water before work, but I do not see much point in this, maleic anhydride interacts with water, but if it is not enough in nylon, then there will be nothing to interact with. Therefore, it makes no sense to stock up on fishing line for a long period of time, a breaking or constantly breaking line, which, moreover, does not want to leave the reel itself, can significantly complicate the work.

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need to change the cutting tool or line in the reel. Very often, when trying to unscrew the mowing head, users simply render it unusable, not suspecting that it is unscrewing in the opposite direction. To prevent this from happening, if you need to replace the tool, we recommend that you read the step-by-step instructions below.

  • Stop the mowers engine or power off the trimmer before placing the line into the spool to avoid injury from accidentally starting the cutting tool.
  • Unscrew the nozzle attached to the gearbox shaft. To do this, the shaft must be fixed by aligning the holes on the washer and on the axle, and inserting a metal rod or screwdriver into them.
  • Unscrew the nozzle. You should be aware that the thread on the shaft is left-hand. Therefore, turn the trimmer coil to the right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the clips. To remove it, you will need to sink these latches into the case, squeezing the edges of the cover. If your trimmer has a semi-automatic mowing head with a button on the bottom, then the disassembly of the attachment should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
  • Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine stress and higher gas mileage.
  • Find the midpoint of the line by folding it in half. You will have a loop.
  • Special grooves are cut inside the coil (there may be holes). Insert a loop of line into this groove.
  • Wind the line around the spool by turning it counterclockwise. It is necessary to fill in the cord as evenly as possible, the turns should lie down without overlap and with good tension. When winding is finished, leave free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
  • Assemble the mowing head. Be sure to insert the spring and washer (if applicable) before final assembly of the accessory. Place the spool in the body and thread the ends of the cord through the holes or eyelets.
  • Put on the cover and secure it with the snaps.
  • Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (against the arrows).

Classification by filling method

The trimmer head can have several methods for threading the line:

  • Quick Chargers. The new cord is wound without disassembling the coil, in other words, it is not necessary to remove it from the device. The end of the new element is pushed into the coil and then wound a certain number of times. When a certain value is reached, the cord is cut. This type of trimmer head is made by Shindaiwa and Speed-Freed.
  • Collapsible. Here the title itself speaks for itself. To replace a new cord, you need to remove the reel from the equipment, then unwind the old fishing line and wind the newest.

Disassembly and repair of the lower gear of lawn mowers, trimmers


One of the common devices designed for cutting grass is the trimmer. It is very easy to operate and maintain. That is why he became popular among the population. Its significant advantage is its low weight. Even a child can handle such equipment.

One of the common devices created for cutting grass is the trimmer. It is very easy to operate and maintain. That is why he became popular among the population. Its significant advantage is its low weight. Even a child can handle such equipment.

Design features

It should be emphasized that the trimmer cutter head contains special arrows. They allow you to make rotational movements of the coil in different directions. If it becomes necessary to wind the line in the direction of rotation of the shaft, it turns to a specific position. A huge amount of wound cord can damage the equipment. Two arrows are contained only on models brought from other countries. Currently on the market there are heads with one arrow.

If, after the impact of the automatic head, the cord is not wound, then its previous winding was performed incorrectly. In other words, after the trimmer head was installed, the user did not pull the ends of the line out of the grooves. Another nasty moment when mowing grass can be the sintering of the coil turns.

Why is this happening? This happens when the cord meets a solid object. With all this, it slows down sharply and with the next movement the line begins to enter the inside of the device. Thus, it falls on the spool and sticks together. Because of this, the employee has to take a break and correct the situation. But this can be really avoided. Before installing the reel, you need to treat the line with a special silicone substance.

For different models of trimmers, an automatic head is used, consisting of 2 parts. a body and a spool. Both elements contain springs. The second part can be produced in several versions:

  • Single-section. both parts of the line are wound together;
  • Two-piece. each end is wound on a specific part; this type is more effective, because the line does not get tangled or sintered.

There is a common and cheap method to transform a one-piece spool into a two-piece spool. A strong plate is useful for this. It is necessary to cut a circle from it, the diameter of which should be equal to the thickness of the spool. With all this, the thickness is taken near the place where the fishing line is wound. This circle moves freely. Further, a cut is made on the ring, put on a spool and connected with glue or tape. As a result, you can wind the line on the desired section. The head for the universal trimmer can have from 2 to four holes, which are located opposite each other. Mowing ends come out of them. In addition to the reels presented, there are heads where a certain size of fishing line is inserted. In this case, the number of whiskers increases to 12. Many users believe that such a device is quite comfortable. But, not all people adhere to this idea. They believe that in this situation, the line will have to be spent more. In addition, to replace it, you need to stop the workflow. The trimmer head is available in various sizes and is suitable for cutting grass, shrubs and trees. Before you buy a trimmer, you need to study the area, as well as the features of the equipment. So, we learned why the universal trimmer head serves and how to fill it correctly.

In this I show you how to disassemble the coil at a gasoline trimmer, as well as how to properly wind the EFCO STARK 25 replacement trimmer head HD OLEO-MAC replacement trimmer head Gasoline trimmer Efco Stark 25 Light and reliable gasoline. In this I show how to disassemble the coil from a gasoline trimmer, as well as how to properly wind the fishing line on it. This will be useful for beginners and those who have just started getting acquainted with trimmers / lawn mowers, etc. I show this tutorial on my trimmer. In this I show how to disassemble the coil from a gasoline trimmer, as well as how to wind it correctly How to choose the right coil with fishing line for lawn mowers or lawn mowers in Ukraine. Mowing trimmer head.


The main technical features of the trimmer are:

  • Power;
  • Equipment weight;
  • Type of power supply (from the network or using a battery);
  • Placement of the motor (top or bottom);
  • Cutting element type;
  • Rod type.

All this must be taken into account, take this or that device.

Noise inside the coil

The noise inside the mechanism case can indicate both minor and serious malfunctions. Having heard extraneous sounds in the form of creaks or rattling, it is worth stopping the operation of the device until the essence of the problems is clarified. In any case, you will need to disassemble the spinning reel and visually inspect the transmission mechanism. The reason may lie in the penetration of dirt into the housing, when sand and solid dust fractions get on the surface of gear wheels and shafts, as well as in the working parts of the bearings.

The problem is solved by mechanical cleaning and flushing of the unit, followed by filling with fresh lubricants. If deformation of parts and bearings is detected, which is most likely, they will need to be completely replaced with new parts.

The most popular problems and their repair

In the continuation of the article, we will consider a number of the most common problems with non-inertia systems. These malfunctions, which are not critical for the complete failure of the mechanism, can be associated with both defects in the materials of the product, and with incorrect operation of the device. After all, the unfavorable conditions under which the units of the grinder work, and this is high humidity, abrasive sand particles and elementary dirt, of course only have a negative effect on the operation of the unit as a whole, despite the scrupulousness and careful attitude towards it.

But often, in the practice of fishing, even with the observance of the minimum rules for the use of inertialess and regular maintenance of gears and bearings, these troubles occur due to the worked time and resources that exceed the maximum capabilities of the units and parts of the product. The presented breakdowns of the coils should not embarrass and unsettle the angler, because he must be able to put the device in order on his own, which is quite a doable job.

Self-tightening clutch

The self-tightening of the friction clutch, to the great regret of the angler, should be classified as a malfunction in which it is not possible to repair the spinning reel. The malfunction often causes the line to break, especially if fishing is carried out on delicate tackle with small diameters of cords, unexpectedly manifesting itself at the moments of the thread blowing off. When fishing on heavy tackle with thick cords, spontaneous clamping of the friction clutch can result in a breakdown of the transmission mechanism itself. An irreparable defect is the lot of a poor-quality assembly of a cheap product, which, if possible, must be returned under the manufacturer’s warranty and a new product must be purchased.

Dismantling the line roller

After manipulating the parts and the body of the mechanism, we proceed to disassembling the line. It is not possible to build an unambiguous algorithm for dismantling the parts of this element, due to significant differences in the design of the device in each version of the device. For the reliability of the work, it is recommended to make a step-by-step photographic recording of each operation being carried out, which today is an event quite accessible to a common man in the street, using a smartphone for these purposes.

Having fixed the disassembly process in photographs, after diagnosing and repairing the spinning reel, the angler can easily cope with its reassembly, without errors, bringing the product back to its original and workable form.

How to Remove the Coil From an Electric Trimmer

How to tuck the line into the trimmer?

So that the area near the house always looks well-groomed and careful, it needs to be cut often. Fortunately, modern technology allows you to solve this problem without unnecessary physical effort. Electric trimmers are so simple to operate and maintain that even a child can mow with them. The main thing is to figure out in advance how to fill the line in the trimmer.

Line breaks under the clutch nut

The problem under consideration threatens the loss of baits and is inherent in new, only acquired mechanisms with a front location of the friction brake adjustment knob, during the so-called running of the reel on the first fishing trips. In devices of these designs, the fixing nut is raised above the edge of the spool to a height of 1–2 mm. When the angler reels in the rig, the line will often snag on the nut and pull under the edge of the spool, further entangling, warping and breaking the line. To eliminate incorrectness during winding, it is necessary to disassemble the spinning reel with the spool line, unscrew the clamping nut with washers of the friction brake device and replace the factory felt pad with exactly the same size, only cut from thin plastic.

Important! Particular attention is paid to the problem by purchasing inexpensive mechanisms, in which manufacturers most often sin by installing low-quality gaskets in this unit.
