How To Put The Knife On The Trimmer

Filling the line into the trimmer The line feed system from the trimmer can be manual, semi-automatic and automatic. Here is an example of how to thread the line into the trimmer (Trimmer BOSCH Art 30).

Spare coil storage space

It is very simple to install such a fishing line into the reel according to the internal scheme inside the reel. We insert the center of the line with a metal mount in the upper part of the reel, and draw the ends of the line along the grooves and bring it out.

Thick line

It is stored at the top of the trimmer body.

In addition to the standard lawn line, my trimmer has a thick line for cutting rough weeds. It has the shape of a pigtail, i.E. Three lines are tightly intertwined. This line has its own spool. Material you can see

A little advice. Try not to let the line come into contact with hard objects when cutting. With this contact, the line will be cut. And since in this trimmer the line is not fed automatically, then every time you have to stop work, remove the reel and release the line again.

We fill the line in the trimmer.

I want to devote today’s article to the sore subject of summer residents and gardeners of the entire post-Soviet space How to fill the line in the trimmer. Not many trimmer manufacturers answer this question in their instruction manuals. Therefore, it is difficult for ordinary gardeners to figure out how to do it correctly.

I want to start with a brief description of the technical characteristics of the trimmers.

So, trimmers are electric and gasoline. The cutting element for trimmers can be a line and a knife. The line is ordinary, four. Pentahedral and intertwined (in the form of a pigtail). Knives come in 2, 3 and 4 bladed knives. There are also plastic and metal knives.

The line feed system from the trimmer is manual, semi-automatic and automatic.

The development engineers who create new models of trimmers clearly calculate the diameter (thickness) of the line and the number of knife blades, according to the power of the trimmers. Otherwise, the motor is overloaded, resulting in damage. And these are additional and significant costs.

Trimmers on the market today:

With one nozzle only with a line.
With two line nozzles and three-four-blade knife.
With one nozzle only three-four-bladed knife.

Our Kulibins have long ago learned to improve any mechanisms. So, for example, some gardeners make successful, in their opinion, replacement of fishing line with a metal cable, or fishing line. But at the same time, they do not think about the safety of their own and their loved ones, because, like a cable with the power of a working trimmer, it can easily break out and not only injure the mower and others, but leave him crippled for life. Using a fishing line can and gives a better effect, I have never personally tried it than a trimmer line, but such work has a number of inconveniences: when it comes into contact with hard objects, it loosens or can simply be pulled out of the reel without limit.

So, what is called closer to the topic. Here is an example of how to thread the line into the trimmer (Trimmer BOSCH Art 30). Everything is very simple. We started.

After you have chosen the line for refueling, you need to cut off the required amount of line, because all the line in the skein will not be wound into the reel.

Cut off and start winding.

Remove the coil and the protective cover from the coil.

They took it off. We fasten one end of the line into the gap and carefully and evenly wind the line.

The amount of line should be such that the protective cover of the reel closes and the line on the reel unwinds a little by itself.

We put the other end of the line into the hole in the protective casing.

Next, we take the coil and the protective cover of the coil. We squirt the end of the line from the reel into the metal hole on the reel’s protective cover. We tighten the line a little.

We put it all on the trimmer. Turn the coil clockwise until it clicks.

They fixed it. Now we connect the trimmer to the network. We put the trimmer in the starting position for work. We turn on the trimmer. Excessive line length will be cut on the trimming blade.

Coil in trimmer

That’s all we start working on.

How to put the knife on the trimmer

With the arrival of summer, many owners of personal plots are worried about the question of how to put the knife on the trimmer. No less relevant are the questions of why and when it is advisable to replace the line on the brushcutter with a more durable cutting element. In our article we will try to disassemble all this and give useful recommendations to summer residents.

What knives to put on an electric and gas cutter

Before buying and putting a knife on the brushcutter, we will find out what they are and in what cases they are used. Today manufacturers offer the consumer a large number of types of these consumables. In general, all cutting tools designed for mowing grass can be classified:

  • By the type of material from which it is made;
  • According to the shape of its cutting blades.

The main material for making trimmer knives can be plastic or metal. The use of such consumables largely depends on two parameters:

  • Type of brushcutters;
  • Mowing areas.

For safety reasons, manufacturers do not recommend putting steel knives on electric trimmers. Almost all brushcutters powered by an electric network and a battery are equipped with plastic blades. Depending on the manufacturer, they can be of a solid disc-shaped design, with several blades or in the form of a special mowing head providing for the installation of removable plastic blades.

How To Put The Knife On The Trimmer

Straight bar for petrol trimmer and curved for electric

To put a metal knife on an electric trimmer is not allowed by its design features.

  1. The curved bar of the machine reduces the distance from its working part to the mower’s feet. In the event of a collision of the blades with a stone or other solid object, the scythe is thrown to the feet.
  2. The high torque we mentioned above, in the event of a metal blade hitting a hard object, transfers a heavy load to the trimmer flex shaft and its motor. What causes them to fail prematurely.
  3. The handle of the electric scythe most often does not have a limiting bar acting as a stop. That does not exclude injury to the legs.

It is these features that make it possible to use only plastic knives on trimmers with electric motors. Upon collision with an obstacle, the blades are destroyed, thereby protecting the mower’s legs from possible injury.

The use of metal knives only on gasoline trimmers is also due to design features.

  1. The straight bar design increases leg clearance for complete safety.
  2. Comfortable U-shaped and J-shaped handles for a firm grip. The D-shaped handles of the brushcutter are equipped with a limiter resting on the leg of the mower, which does not allow the head to come close to the feet when the cutting disc meets a solid obstacle.
  3. The clutch of the gasoline engine allows smooth acceleration to the optimum level. And when the blade hits a hard surface, it can absorb part of the impact.

Thus, petrol trimmers with a metal blade installed are best used in large areas. They will successfully cope not only with high coarse grass, weeds, burdocks and nettles, but also shrubs, as well as young trees.

The shape of the blades of the disc supplied to the trimmer does not in any way affect the quality of the work performed. Speed ​​does not depend on them either. Triangular, trapezoidal, rectangular shapes are all the marketing ploy of manufacturers.

Why you need to put the knife on the trimmer

A trimmer with a knife installed on it is most convenient to use for more comfortable mowing of tall and coarse grass in the country. The line on the brushcutter cannot cope in such cases. Thin tears very quickly. Using 2.3mm thick cord or homemade rods with cables causes the vegetation to wrap around the spool. This increases the load on the engine. As a result, the piston group and other moving parts of the unit wear out very quickly.

If the weeds are mowed with an electric trimmer without a knife, only a fishing line, even a thick one with a curly section, will not solve the problem. There is always a risk of overheating the motor and damaging the flexible shaft. And it’s all about the large torque of the electric motor. Grass wrapped around the spindle creates strong resistance to the shaft, which resembles a speedometer cable, which does not withstand and twists.

In order to protect equipment from premature wear, manufacturers have provided for the possibility of installing special knives on trimmers. The design and shape of the existing cutting elements allows you to easily cope not only with coarse and overgrown grass, but also to successfully deal with young shrub growth.

How to put a knife on the trimmer correctly

Putting the knife on the trimmer is not that difficult. The manufacturer completes its tools with a special pin that allows you to block the gearbox and a wrench with which the spool and fishing line are unscrewed. The most important thing is to observe safety precautions and the sequence of assembly and disassembly when changing cutting elements.

The algorithm for setting the knife to the trimmer is as follows:

  1. Remove the protective cover;
  2. We block the drive. To do this, it is necessary to align the two holes in the shaft hub and in the gearbox cup. After combining them, insert a pin into the holes;
  3. We unscrew the spool with line or the attachment nut holding the boot (if the trimmer has not been used yet) from the hub clockwise;
  4. Next, we install the cutting knife, so that the slots on the hub washer coincide with the recesses in the hole of the cutting disc;
  5. Install the boot;
  6. We tighten the fastening nut (counterclockwise) while holding the locking pin;
  7. We tighten it using a tubular wrench;
  8. We return the protective cover to its place.

As you can see, there is nothing complicated. Now you can safely start mowing weeds on the site.

Types of fishing line

The trimmer thread can be divided into types according to its diameter. It can start from the smallest 1.2 millimeters and go up to 4 millimeters. The most commonly used is the 2 millimeter diameter. But it must be selected strictly individually, based on the specific model of the device. Often the required product diameter is indicated in the product passport. Generally, the more powerful the trimmer, the larger the line diameter should be. For example, it is best to wind a thread with a diameter of 2.4 millimeters on a reel of a brushcutter, and for a product with a weak motor, a thread diameter of 1.6 millimeters is suitable.

Fishing lines also differ in the type of section. It can be round (for mowing ordinary grass), square (for soft and often mown grass), with sharp edges (for tall grass), with notches (for thin grass), and also complex (see). The latter can not be refueled in all types of devices. It should be noted that the line is intended exclusively for mowing grass. To cope with other types of plants, it is necessary to use a brushcutter with a sharp knife. The length of the threads that can be tucked into the trimmer can range from 10 to 100 meters.

Step-by-step instructions on how to wind the line on the trimmer spool

With the arrival of spring, you often spend your time at the cottage or in your garden. The trimmer will protect you from problems such as grass and weeds. This tool easily trims and mows grass in difficult terrain, where a conventional lawnmower cannot do it. Trimmer. A very effective and convenient tool for cutting grass along fences, flower beds, houses and garden aisles. Several types of garden trimmer have been invented (petrol, electric and battery). It would seem that everything is fine, you have such a wonderful assistant in your arsenal, but over time, the cutting element wears out and it becomes necessary to replace the finished line. And not everyone knows how to fill the line in the trimmer. We suggest using step-by-step instructions with attached graphs.

Instructions on how to wind the line on the trimmer spool

  1. 1. First you need to disassemble the trimmer head. Press the latch on the product body and turn the cover clockwise. We take out the bobbin.
  2. Now we have to figure out how to wind the line on the trimmer reel. We measure about 6-7m of fishing line and insert its end into the hole in the bobbin.
  3. We reel the fishing line from both sides. The winding direction is always indicated by an arrow on the bobbin.
  4. Leave the ends of the 15 cm cutter free. Do not wind too much line. Leave 6mm between the outer edge of the bobbin and the line.
  5. Insert the remaining two ends of the line into opposite holes in the bobbin.
  6. We fix both ends in the grooves on the head body.
  7. Place the spring carefully back into the bobbin guides and into the head body.
  8. In order to thread the line into the trimmer correctly, the bobbin must go back into the head body (press it slightly). Pull the loose ends of the line out if necessary. Pull the ends of the cutting element sharply one by one until they come out of the slots in the bobbin and pass freely through the holes in the head.
  9. So, we figured out how to wind the line on the trimmer reel. It remains only to align all the grooves on the head body and close the cover. Then we press on the bobbin and begin to rotate it counterclockwise until it stops. While holding the bobbin, turn it slightly clockwise and release it. If there was a clicking sound, then it snapped into the head. If this did not happen, then you need to repeat the action again.
  10. Pull out the free ends of the line until they stop.

How to wind the line onto the trimmer spool

Product spools can have different yarn feeding systems. It can be manual, semi-automatic or automatic feeding. Depending on this, it is necessary to wind the fishing line. So how do you thread the bobbin? To begin with, the cap is unscrewed on the coil (see). If the thread on it is left-handed, then you need to turn it clockwise, and not as usual.

Such a thread is made so that during the operation of the product, the trimmer head cannot unwind. To thread the thread, you need about 5 meters of material (see). It must be folded strictly in half, the center must be inserted into a place specially designated on the device and wound in the direction of the arrow, which should be drawn on the coil, as in. After that, you just need to tighten the cap.

We wind the line on the trimmer spool

Owners who have their own backyard plots often face the problem of lawn maintenance, namely, the need for high-quality mowing of grass. For these purposes, either a manual or a scythe powered by electricity trimmer is used (see). It is clear that working with the electric model is much easier and faster. The grass is mowed with a line rotating at high speeds. But during operation, the thread wears out over time and requires a change. So how do you wind the line around the trimmer reel with your own hands?

How to put the spool on the trimmer How to properly wind the line on the trimmer spool

Many, having worked out the factory line on a recently purchased trimmer, try to wind a new one, but cannot, because they do not know how to properly wind the line on the trimmer spool (bobbin). It seems that there is an instruction, but it still does not work. Let’s try to deal with this issue in this article.

So, to wind the line, you first need to remove the spool from the trimmer. The method of removal will depend on the type of trimmer.

On small, bottom motor electric trimmers (when operating near the ground), the reel usually has two buttons on the sides. Click on them and disconnect one half of the coil body from the second, which remains on the trimmer. Together with the first half, the inner part is also taken out, on which the fishing line is directly wound. When disassembling, be careful: there is a spring inside that can fly out and get lost.

On electric and gasoline trimmers with a curved bar (on such trimmers it is not yet possible to put a knife), you need to grab the coil body with one hand, and with the other hand you need to start rotating the lamb on it counterclockwise. It is he who attaches the coil to the trimmer bar. Having unscrewed the lamb, carefully remove the entire coil, trying not to lose the spring inside.

On electric and gasoline trimmers with a straight bar and a gearbox at its end (on such trimmers, in addition to the fishing line, you can also install a knife), we look for a hole under the coil, insert, for example, a screwdriver into it, quietly rotate the coil until the screwdriver crawls even deeper, and the coil will lock. Now we turn the whole coil clockwise (since the thread is left-handed) and remove it from the trimmer. Then we disassemble the coil. It can be assembled using latches or twisted with a lamb. If the coil is on latches, then press on the sides on the base of the latches so that they bend and release one half of the coil body from the other. We just unscrew the lamb. There may also be a third type of connection of two halves of such a coil: with it, you need to grab the lower part with one hand, and # 8212 with the other; top, and start turning them in opposite directions. When disassembling such a coil, you must also make sure that the spring inside is not lost.

Now, having removed and disassembled the coil, we proceed, in fact, to the main question # 8212; how to properly wind the fishing line.

If your coil is designed to work with only one tendril, then it’s simple. You need to rewind 2-4 m of fishing line (depending on the size of the reel), find a fixing hole for the line on the inside of the reel, insert one end of the line there and start winding the line in the direction opposite to the direction of rotation of the reel on the trimmer. On the inside of the reel, they usually indicate with an arrow in which direction to wind the line. Having reeled up the fishing line, we leave a small piece of it unwound to expose it. We fix this piece in a special groove located on the inside of the reel and designed so that at the time of collecting the reel the line does not unwind. If there is no such groove, then you will have to hold the fishing line with your finger to prevent it from unwinding during the further collection of the coil. Next, we take the outer part of the coil and thread the outer piece of fishing line into the existing hole, assemble and put the coil back on the trimmer.

If the coil is designed to work with two antennae, then do the following. On the inside of the reel, we look at how many grooves there are for winding the fishing line. There may be one or two of them. If there is one groove, then both tendrils are wound along this one groove. If there are two grooves # 8212; then each antenna is wound along its own groove. A reel with one groove must have a through hole through which the line is threaded. We unwind 2-4 m of fishing line, thread it through this hole so that it sticks out equally on each side of the fishing line. And we simultaneously wind both antennae of the fishing line in the same direction, opposite to the direction of rotation of the coil on the trimmer and coinciding with the direction indicated by the arrow on the inside of the coil. We leave a little fishing line unwound, fix the resulting ends in special grooves, and if they are not there # 8212; hold with your fingers. We pass both ends into the existing holes on the outer casing of the coil. We collect the coil and attach it to the trimmer.

If there are two grooves, fold a piece of fishing line 2-4 m long in half, insert the loop obtained at the place of the bend into the groove between the two grooves, and simultaneously wind both ends of the fishing line, each along its own groove. Further actions are similar to the previous option.

There are also spools in which the line is passed through a through hole on the inner part, the ends of the line, without winding, are passed completely through the holes on the outer body of the reel, collect the coil and begin to rotate the button, which is usually pressed, in order to release the line along as it wears out. Rotate the button # 8212; the fishing line itself is wound inside. At the same time, twist it to # 171; wrong # 187; direction will not work, since it can only rotate in one direction.

That’s all on this issue. Now you know how to properly wind the line around the trimmer spool.

Features of discs for brushcutters

Knife discs are produced in plastic and metal, as well as in various shapes to perform various tasks.

  1. Two-, three- and four-bladed knives with pronounced blades are used for mowing grass and tree growth. However, they are not suitable for making hay, as they grind the shoots by chopping them several times.
  2. Massive four-blade discs are designed not only for clearing the ground from grass, but also for mowing hay. They prevent the shoots from being cut over and over again, making them suitable for winter harvesting.
  3. Discs with cutting edges around the perimeter are relevant for beveling reeds and reeds. These knives are very heavy, a necessary quality to cut through thick stems.
  4. Professional saw blades for hedge trimmers and brushcutters allow you to cut small trees and bushes.

Plastic knives are used as an alternative to metal discs. They do not need to be firmly fixed in the head, but they rotate as a result of the action of centrifugal force. The strength of plastic knives is high, so the service life is quite long.

When is the use of knives relevant?

When using brushcutters in summer cottages, the most popular attachment is the fishing line. It has a low price, is suitable for different trim heads, and is safe to use. The disadvantage of using a fishing line is that it is convenient only for mowing low growth. In other situations, the string will kick in immediately, regardless of whether a petrol or electric trimmer is used. In addition, vegetation is wound around the spindle, which creates significant resistance on the shaft and leads to its breakage. This can also provoke failure of the piston system in petrol cutters or engine burnout in electric trimmers.

Therefore, for mowing tall or hard vegetation, various attachments are used. So, for harvesting high and coarse grass, thin shoots of trees and shrubs, it is better to install and use a disc. This nozzle clogs much less often, which contributes to the greater wear resistance of the equipment.

Blades

The number of blades is important when solving diverse tasks. So, for grinding grass, two or three pieces are enough. To harvest hay, it is necessary that there are four to eight blades on the disc. To destroy small shoots of trees and shrubs, instead of blades, the discs must have a large number of small teeth.

Rules for replacing knives on the grass trimmer

If the trimmer disc is used regularly, it will need to be removed and sharpened or replaced from time to time. This part can be made of metal or plastic, have a different number of blades, but the replacement process remains the same. Over, this procedure is similar for equipment from different manufacturers, be it Carver or Huter, but slight differences are possible. It is quite simple to change the knife on the trimmer if you follow the safety precautions and know the correct procedure, the description of which can be found in the user manual. The entire replacement process step by step, as well as the method of self-sharpening knives, will be described in this material.

Material

It is not recommended to put metal knives on electric scythes, since the design features make their use dangerous for the user. This is due to the curved shape of the rod, the absence of stops on the handles, as well as the high rotation speed.

Plastic knives should be used on gooseneck trimmers for safety reasons. Their purpose is mowing soft grasses, dead wood. Whereas metal discs do an excellent job with tall, dense, hard shoots, bushes, as well as tree shoots.

Trimmer disc installation procedure

Attaching the blade to the trimmer is easy. To do this, use a complete wrench that disconnects the cutting attachment and a pin that blocks the gearbox. The procedure is as follows.

  1. First of all, you should disconnect the electric trimmer from the mains, just turn off the gasoline trimmer. Disconnect protective cover and move to one side.
  2. Next, you need to align the holes on the gearbox and the shaft in order to insert the pin into them and block the drive.
  3. If a spool with line was used, it must be unscrewed clockwise.
  4. Then you need to find a nut to twist the knife.
  5. The next step is to install the knives. Trimmer owners often wonder which side to put the disc on. This must be done so that the marking with numbers and letters is on top.
  6. Then you need to put a boot on top, and above it a fixing nut, which must be tightened tightly with a wrench.
  7. The last step is to install the protective cover.

As you can see, the procedure is very simple and the same for many brands, be it Stihl or Husqvarna equipment.
