How to assemble a trimmer for grass correctly. instructions photo video

Garden trimmers for grass are similar in design. Detailed instructions for one model will help to understand the intricacies of installation of analogues. Consider the main stages of the assembly of the electrimmer on the example of the model Fubag Fet 1200r.

We fasten the handle of the tool

Unscrew the screw “lamb” 2. Remove the upper fastener cover

To adjust the handle, you need to loosen the lamb and move it. Then the screw should be fixed.

Fubag electrimmers equipped with rubberized handles, which increases the convenience and safety of use. They allow you to reliably hold the tool even in wet hands.

Install a protective casing

Combine holes in the protective casing and in the mounting bar.

We fix the casing on the bar with screws with washers using the key from the kit.

In this model, the casing is attached with metal plates on both sides. This guarantees additional reliability and durability of the trimmer for grass.

The casing itself is made of dense, but elastic plastic. Such material will definitely not break off when hitting minor obstacles. We advise you to pay attention to this if you are only going to Select an electric trimmer for grass or benzotrimer.

We fix the shoulder belt

One of the simplest manipulations when assembling an electrimmer. Many will understand how the shoulder belt is attached intuitively. For those who are not sure, we decided to add several important points to the instructions:

Combine a carbine with a ring for fastening belt 2. Adjust the position of the mounting ring on the bar 3. We fix the ring with a fixing screw

Install the coil with a fishing line

First, combine the hole on the puck with the hole in the gearbox and stop a special rod.

Unscrew the mounting nut from the hub clockwise. 3. Remove the cup from the shaft and the squeeze puck

We twist the coil with a fishing line counterclockwise to the stop, holding the rod.

When choosing a trimmer for the grass, you should take into account the quality of the spool from the kit. Often it is the coil that becomes the subject of savings to reduce the total price for goods. How to identify a disadvantage? A good spool is distinguished by the quality of plastic, easily opens and allows you to season the fishing line for a trimmer without any difficulty.

How to assemble a gasoline trimmer for grass: the procedure and video instructions

As a rule, devices designed for mowing grass and similar to them are quite bulky.

The vast majority of trimmers of any type are delivered in disassembled form, packing in a cardboard box, so before starting work, such an apparatus must be assembled.

In addition, a trimmer for grass often has to collect after winter, because some of the owners disassemble this device so that during storage it takes less space.

What is the assembly of a lawn mower?

The assembly means the connection of fully functional devices and assemblies, that is:

  • motor with control and clutch elements (only gasoline);
  • drive shaft;
  • pens or handles;
  • protective casing;
  • shoulder belt or suspension system.

Tools and fasteners

The set of each apparatus, regardless of its type, includes standard fasteners and a universal tool.

The shape of the heads of all bolts, regardless of their diameter and length, corresponds to the instrument that is included in the set of the trimmer for grass.

In the case of loss of some kind of fastener element, select its full analogue, if this is not possible, then you can neglect the shape of the hat, but all other parameters, that is:

However, such an incomplete analogue will force you to use, in addition to the full.time, an additional tool is also not too convenient. If you have lost a full.time tool, then select the closest analogue or buy the same device in any store selling trimmers.

Process description

The assembly process is described in detail in the instructions for the operation of each device, and the shape and configuration of finished blocks in most cases do not allow them to connect them incorrectly.

The main condition for the correct and fast assembly is the correct arrangement of the blocks relative to each other, as well as the combination of their holes.

Devices with an upper engine is more convenient to collect on a table where all blocks can be placed in the order of their docking.

Where the details connect several bolts, act like this:

  • Place both elements as they will have to look in a collected state (when assembling a gasoline trimmer for the grass, put the motor on the table with a clutch, then install the shaft with gearboxes on it, the upper of which is the protection of the clutch bowl);
  • Combine holes;
  • Bait one bolt by twisting it at 2–5 revolutions;
  • make the following bolts;
  • Press the details to each other to make sure that they are correctly located;
  • Twist (do not tighten) all the bolts in turn the cross on the cross;
  • Make sure again that both blocks are located correctly;
  • Tighten all the bolts with the required effort (indicated in the operating instructions) in the same order, that is, the cross on the cross.


The most convenient is the installation of primarily the largest blocks, that is, the engine and the drive shaft, then the handle and the protective casing are attached to this design, and lastly the cutting tool is put.

If the device is supplied with a disassembled shaft, that is, a gearbox and clutch are not installed on it, then start the assembly with the shaft, because it is the most overall detail.

When assembling the shaft, be sure to combine the lubricants on it and gearboxes, because the lack of lubrication will quickly kill the shaft. In addition, combine the slots on the rifle rod and gearboxes, if this is not done and the details are planted through force, then you can damage them.

Be sure to check the presence of lubricant in gearboxes and a drive shaft, because despite the assurances of the manufacturer that all the elements are lubricated and ready to work, this is often wrong.

Chinese manufacturers of cheap technology sin especially often in this. If the shaft is delivered with gearboxes, then spend a little time to disassemble them to check the amount of lubricant. it is much cheaper to do this before the first launch than to change the drive shaft in a few days or buy a new trimmer for grass.

In addition, we recommend lubricating gearboxes and shaft, as well as change oil in a four.stroke motor before each season start.

Do not forget that the lower gearbox and the mounting of the handle should be properly located on the drive shaft so that the gear shaft is directed down and the handle is directed upward.

On all devices with the rear engine, the handle is the team and consists of:

First fasten the connector to the shaft, then insert both handles into it.

Some models of trimmers are equipped with handles with a connecting sleeve, in this case:

Remember. the location of the handle and the angles of inclination of the handles are adjusted to the operator, so if you experience discomfort when working with a motorcycle or benzo.cosa, then adjust these details for yourself.

The right handle is designed to install engine control elements, so for right.handed it is put on the right side. If you are left.handed, then put the right handle on the left side.

Lastly, collect a cutting tool. Use exactly those protective washers and cups that correspond to the selected tool.

If you install other protective elements of the gearbox, then strong vibrations may occur due to impaired balancing.

If it is more convenient for you to collect a trimmer for grass in some other sequence and you do not make mistakes, then do as you are used to. After all, this or that order is designed to facilitate the assembly, but is not mandatory.

How to redo a trimmer for grass from fishing line to a knife?

If your device belongs to those on which you can install a knife or disk, but you bought it only with a coil, then to remake to work with a knife, you will need to buy:

  • flange washer under the knife;
  • pressing washer;
  • gearbox;
  • nut;
  • Protective plastic casing of the corresponding size.

Remember, the flange washer needs to be purchased by detailing, in which its article is indicated. When selecting a “eye” there is a great chance to make a mistake and take a part that is not suitable for your trimmer. All other details are universal.

In this section, we prepared video videos in which it is shown how to change the coil from fishing line to a knife or disk (mill) on various trimmers.

Repair of the starter of the gas tanker, lawn mowers, trimmers for the grass with your own hands

No matter how high.quality gasoline tools you use, everything can happen to it in the process of construction, and at the most inappropriate moment for this moment. Often problems arise due to the breakdown of the starter. It happens that you will get drunk with a gasoline hole for installing the fencing pillars or mowing the grass with a trimmer, you will start starting the unit, and just have time to pull the starter handle a couple of times, as the rope breaks off, and the engine has already started, dashingly wrapping the rest of the cord to the flywheel, the spring bursts run to the new store buy. But these, of course, are extremes.

Today we will consider the most common case when the breakdown is not so serious and show how to carry out the repair of the starter with your own hands if the cord has broken without any destructive consequences or is not wound due to the fact that the spring just flew inside, went out of the cloth. At least initially I want to believe in it. But in order to find out whether it is or not, you will need to disassemble the starter.

Necessary tools and materials

The following tools and materials will be needed for the maintenance of the gearbox:

Hexagonal key for opening the reducer lubricant hole

Usually, such a key is included with a motorcycle or trimmer.

The next tool is a regular medical syringe with a volume of 10 ml. It is with the help of a syringe that the lubricant enters the gearbox.

It is recommended to use proprietary lubrication from the manufacturer Motokos. In extreme cases, you can use any lubricant to lubricate rotating mechanisms, for example, Litol 24.

We open the gearbox

In order to gain access to the gearbox, it should be opened. To do this is quite simple. you need to unscrew the gearbox with a hexagonal key. This bolt for all Motokos is in the same place. directly near the working body.

Spring refueling action

The diameter of the tube with grease does not correspond to the diameter of the gearbox

In order to easily make lubrication into the gearbox, it is necessary to use the syringe.

Then a syringe is filled with a tube of a tube.

After which the piston is again inserted into the syringe. The syringe is ready to refuel the lubricant in the gearbox.


The syringe is inserted into the gearbox hole


First, the syringe is inserted into the gearbox hole.

Squeezing in the gearbox slightly lubricant and turning it for about a quarter turnover

Then you need to squeeze a little grease in the gearbox and turn it for about a quarter of turn.

When all the lubricant is squeezed out, the process can be considered complete

Lubrication is seasoned in small portions. After each supply of lubrication, the gearbox turns on 1/3. 1/4 turnover. It is advisable to choose the amount of lubrication for each refueling so that the gearbox during the lubricant makes a full revolution.

Activation of the gearbox

After the gearbox is filled with lubrication, twist the gearbox and it is well clamped.

Review: Benzotrimmer Kustorez Parma BTK.052. Trimmer for grass gasoline Parma Practitioner BTK-052-K. Budget lawn mower.

For the assembly and subsequent operation of the unit, the manufacturer provided for a complete set with an almost complete set of keys.

To the existing electric trimmer with a capacity of 1 kW, at the insistence of the spouse, “trimmer for grass-veins of the Parma Practice” was ordered. by passport, but in the order of the Internet. store “ “he called up more prosaic” trimmer for grass gasoline Parma Practitioner BTK-052-K “, that’s why he attached the screen from the order page.

Regarding the used abbreviations: “BTK”. more or less clear. which most likely sounds like “a gasoline trimmer for grass-verter or a gas-resistant trimmer for grass-custores”, “052”. denotes the volume of the power unit in the cube. cm.,

But to decipher one more “to”, from the very edge I did not succeed, the reason seemed to me simple. I have not found the same abbreviation anywhere, namely BTK-052-K, without the last letter, t. e. “BTK-052”. There are a lot of offers on the vastness of the Internet, and with the last letter only in one store, it is probably a technical error. The selection of the store itself is due only to the desire to save the opportunity to use the accumulated bonuses. At the time of acquisition, this trimmer for the grass was distinguished by almost the most attractive price, and among the weaker versions of competitors there were no at all. The minus of this purchase can be considered not the most outstanding characteristics of the power unit at 52 cubic meters. cm. Only 2 l. With., I also remember the “in childhood” engine (for self-making) of a smaller volume for cubic centimeters such as D-5, D-6 issued about 5 liters of passport. With., True, he has a little more dimensions, among the current power units there are copies from 43 cubic meters. cm. give out 2.5 liters. With. Well, the second reason for the choice was the “tribute of memory”, as a child under the brand “Parma“. There was a production of power tools at one of the factories of Prikamye and, in particular, the electric counterpart of the famous chainsaws “Friendship” and “Ural”.

The factory delivery of the “hero” of my review consists of two “places”:

1) a box with a power unit and various accessories; 2) “bar” in cardboard packaging, a length of almost 1600 mm.The passport is quite voluminous “to match” the difficulties of a trimmer for grass.

Actually, the assembly scheme fit on the turn of the passport, it was quite enough for me. The completeness of metizes, did not check, because of the reason,

that this unit is subject to vibrations and many “metiz” can spontaneously unscrew, almost immediately in the nearest store bought a “second” set in case of possible losses.There are no lodges inside the box,

internal movement of elements is present, but it is not significant. The power unit with the controls is already delivered, there were some doubts about the need to carry out any adjustments, but this did not require.From the factory delivery to a suitable trimmer condition for the grass, the gasoline “Parma Practitioner BTK-052” is collected in leisurely mode and taking into account the time for

Conducting a passing lubrication of elements of a non.vegetable bar, refueling fuel, in total about an hour. I think this is a very good result.True, before buying, after reading the reviews on our and on sites, I decided to immediately install another “spool”, in the photo it is yellow, the standard seems to be the complaints (the type of “spray” is indicated in the first photo).Of the interesting and useful “highlights” I can pay attention to the “cutter” of the fishing line.

The necessary thing in order to remove the excess fishing line during the semi.automatic “choice” of the fishing line from the “spool”. To control the trimmer, or rather. its launch on

management elements have appropriate explanatory inscriptions.As elements of the setting, there is an adjusting screw of the “idle”.Ergonomics of the control handle is also interesting.

assemble, trimmer, grass, parma, upper, motor

The handle of a slightly anatomical shape, but only “slightly”, in principle, when “using” for a long time. The hand is a little tired, this creative approach was possible for reasons of “mowing of grass (shrubs)”, because the manufacturer declares only 80 kV in the technical characteristics of only 80 kV. m. the site on which work should be carried out, this provision can be interpreted as a time of continuous work, then in principle everything is in order.The belt mount is overruff, but the spring variety is clearly designed

not on a load of 8-10 kg (the weight of a trimmer for grass 8 kg), a springy effect designed to reduce the transmission of vibration on the operator’s shoulder belt is not observed.The fuel tank from the bottom is protected by a special plate, it is on the one hand

How to lubricate the gearbox of a trimmer for grass?

In the upper part of the case, where the gear unit is installed, there is a technological hole that, when operating the trimmer for the grass, is drowned out with a screw. This screw is twisted, and 1.5 2 ml of grease is introduced into the hole using a nose available on a tube. If the lubricant was purchased in another packaging, then a regular disposable medical syringe is suitable for this operation.

After that, the screw is installed in its former place. This procedure, regardless of the user’s recommendations, should be performed every 10 15 hours of operation of a trimmer for grass in working mode. Other reasons for updating or replacing the reducer lubrication are the independent performing of small regulatory work (for example, cleaning and washing the gear of the gearbox before the start of the summer season), repair of the node, preserving the trimmer for grass for the winter period, etc. D.

If the reducer node is disassembled, it is recommended to completely remove the remaining lubricants from the surface of the parts, even if it does not have traces of oxidation and pollution. And only then apply a new grease. After applying the lubricant, it is recommended to handle the shaft several times manually, and make sure that the grease is evenly distributed over all the details of the gearbox.

How to prepare for winter storage?

To prepare a trimmer for grass for winter storage, do the following:

  • Carefully clean the entire surface of the trimmer for grass from the remains of grass;
  • Remove the cutting tool and grease all the metal parts with a thin layer of engine oil or treat with silicone spray;
  • Disconnect the drive shaft from the engine;
  • Remove both gearboxes;
  • Lubricate all the slots of the gearboxes (including from the cutting tool) and a drive shaft rod with any engine or transmission oil, including the development of the engine of the benzotrimer, if you plan to store the device assembly, or any thick lubricant, if separately;
  • Install the gearboxes on the drive shaft (if required);
  • Connect the engine and drive shaft (if required);
  • Install and adjust the handles (if you plan to store them on a trimmer);
  • Pour all gasoline from the tank and tighten the lid of the fuel tank, then start the engine and wait for its stop;
  • After cooling the engine, unscrew the candle from the engine;
  • Pour 1-3 ml of pure motor oil into the combustion chamber, then screw the candle in place and smoothly pull the hand starter cable so that the engine will make several revolutions and evenly distribute the oil;
  • Rinse and blow, or replace the air filter;
  • Rinse the fuel filter (if it is installed on a trimmer).

How to use a gas toss correctly?

The only way to extend the service life of a trimmer for grass is its proper operation. Unfortunately, some of the manufacturers are not interested in the too long service life of their products, so part of the rules that help to more carefully spend the resource of the apparatus are not included in the instructions for the operation of the benzotrimmer.

For this reason, we recommend carefully comply with all the recommendations of this article, even if they are not in the operating manual, because we made recommendations on the basis of:

CGT S20LiDA Cordless Grass Trimmer 2021

  • the experience of operating many owners of devices that they were divided on the pages of various forums;
  • tips of those who are engaged in the repair of motorcycle;
  • Recommendations from the operating manuals of trimmers of the most expensive and high.quality brands.

Since the operation of a trimmer for grass implies not only mowing grass, but also many other actions, we divided it into the following topics:

  • The engine is running.
  • The choice of revolutions.
  • The direction of the mowing.
  • Choosing clothes and protective equipment.
  • Security measures.
  • Transportation and storage.

The engine is running

Despite the fact that the engine of the newly purchased trimmer for the grass is already driven and you can immediately proceed to the mowing of the grass, avoid maximum speed for the first 3-5 hours, because the final grinding of the parts of the cylinder piston group occurs.

If we allow the motor output at maximum speed, then there is a high probability of the appearance of stray on the walls of the cylinders, and this will lead to a sharp drop in the efficiency of the motor, and will also greatly reduce its resource.

The choice of revolutions

The maximum torque of the motor appears at revolutions corresponding to 2/3 of the maximum, and the greatest power appears at revolutions corresponding to 3/4 of the maximum. Therefore, the most effective trimmer for grass mows grass in this range.

The exit to maximum turns slightly reduces power, so during the mowing of grass, focus on the sound of a trimmer for grass and evaluate the speed according to this parameter.

If the load is too high and the rotation speed of the power unit shaft is reduced, add the gas using the corresponding key on the working handle.

As soon as the load decreases and the turns increase, press the gas key less to return the speed of rotation of the motor shaft to the optimal value.

If before you have never used a motorcycle, then until the completion of the run.up, mow only low and non.thick vegetation, which a trimmer head with a fishing line easily copes with. After completing the, the engine will cease to be afraid of maximum revolutions, and you will acquire a sufficient skill to control the motor by ear.

In addition, avoid the long operation of the motor at idle, because because of this, the lubrication of the crankshaft bearing is deteriorated, which can lead to its overheating and jamming.

The direction of the mowing

When working with a motorcycle system in the maximum capture mode, move it so that it goes against the direction of rotation of the cutting tool.

In this case, the knife or disk will repel the device from a possible obstacle, so the trimmer for the grass will not jump out of hands.

In addition, with such a movement, a knife or head is thrown back in front of you, so you will better feel the resistance of the mowing of grass, which means avoid too fast movement and caused by it:

For most trimmers, the right direction of mowing grass is movement from right to left. When moving in the opposite direction, the trimmer for grass continues the mowing of grass, so the probability of a reverse blow increases, due to which the device can be very jerking. Therefore, when moving in the opposite direction, try to capture smaller grass to reduce the load on the device and the probability of a reverse blow.

The choice of maximum maximum capture mode is especially important at:

In addition, when pruning trees, try not to raise a cutting tool very much, but also not to turn it perpendicular, because this can lead to a violation of the carburetor.

This requirement is not relevant only for trimmers-crossbars, whose carburetors work equally effectively in any position.

Choosing clothes and protective equipment

A trimmer for grass is a device of increased danger, so to work with it you need to choose the right clothes and protective equipment.

When going to mow grass, put on only clothes without any straps and fringe, which can tighten a rotating cutting tool.

If you put on shoes with laces, then take measures so that they do not untie. If you have long hair, then limit their mobility by putting on a hat or tied with something. Be sure to put on glasses or a protective mask, because it is likely that the grass cuts will not where it should and falls into the eye.
