      According to Servy statistics, the main faults* when working with trimmers MTD are:

      1. The MTD gas trimmer does not start, there is no spark-formation of reasons: the spark plug is faulty, the ignition coil (magneto) is faulty, the parts of the manual starter are damaged, the fuel system is clogged, the cylinder-piston group is worn out;
      2. The MTD petrol trimmer stalls, possible reasons: blockage of the fuel system (no fuel supply), wear of the cylinder-piston group, misaligned carburetor, blockage of the air filter;
      3. The cutting attachment of the MTD gas trimmer does not rotate, the main reasons: wear of clutch parts (cams, springs, clutch cup), wear of the drive shaft, gearbox is faulty.
      1. The MTD electric trimmer does not turn on: the power button is faulty, the power supply cable is faulty, the graphite brushes are worn out, the engine is burnt out (either the entire stator or the rotor separately);
      2. Electric trimmer MTD does not rotate the cutting attachment, possible reasons: wear of the shaft adapter (bushing connecting the engine shaft and the trimmer shaft), the gearbox is out of order, the trimmer shaft is out of order;
      3. The engine sparks at the MTD trimmer, the main reasons: the engine has completely burned out, or the stator or rotor have burned out separately.

      

      These defects are typical of MTD trimmers (benzo and electric trimmers): some are more common, others less common. And not infrequently, they occur due to the simplest reasons: improper operation (no maintenance is carried out), the use of poor-quality gasoline mixture (oil and gasoline) or power surges and surges, many hours of uninterrupted operation of the trimmer, mowing of the grass that is not appropriate technical capacities of the trimmer.However, with the correct and professional approach, all breakdowns can be easily repaired by the specialists of the Servy service center in Moscow.

      Mtd700. Everything suits. Only now you have to work in the 2nd mode (half-closed damper), as in the 3rd mode (fully open) it seems to choke, mostly at full speed. Some kind of misfire. Maybe someone will tell you. It is not necessary to stick to this model - all two-strokes have the same principle of operation. Thanks in advance.

      There was the same bullshit on the Mtd-790. He took off, cleaned the carburetor - not completely solved the problem.
      It turned out that air was leaking (the crankcase from the cylinder was unscrewed). Tightened the screws - and everything worked like a new one.

      In addition to Denisov Sergey I can add that on my MTD the head of the bolt is attracted by a star-shaped key.

      2os TORX is called, usually 25.

      Cleaning and adjustment of the carburetor is required.

      By the way, working in the second position of the air damper leads to the formation of carbon deposits on the spark plug, piston and, most sadly, rings.

      looks like a clogged water-reflective mesh in the carburetor (located on the right side of the carburetor under the cap screwed with one large screw)

      I have Ryobi700 in hard labor at the dacha worked since 1998 all its motor resource. This Saturday it did not start at all, an autopsy showed that the ring on the piston had been in place for a long time, the piston and head were ejected. the mixture was done 1k30. On the carburetor there are two plastic pipettes, red and white, these are screws of quality and quantity, they are in the shape of a comma and they are very well regulated and you cannot screw up too much. And now I'm looking for a place where you can buy a piston and a head with a set of gaskets. All the services that repair Mtd-ryobi begin to whine “bring it, we'll see if it can be repaired,” but I don't need it, I’ll collect everything in an hour and they will do it until the end of summer until the grass withers.

      Starts up with a closed damper easily. Then at idle for any and after a dozen seconds it stalls. During this time of operation, it practically does not react to gas. I consider the suction through the toe of the crankshaft and the worn out oil seal. IMHO, of course.
      The oil seal is visually worn: the width of the contact of the lip of the oil seal with the shaft is almost 1.5 mm. The oil seal was removed without destruction by complete disassembly of the bearing assembly. They asked for repairs for him, for the oil seal, 250r. To know for sure, but at random - a toad. In general, I pasted an oil seal from the machine on the sealant (an eight-shaft oil seal, either a stem, or a distributor). The inner D is the same, and the outer D is minus 2mm.
      Dries up.
      This weekend - tests.

      Speaking of soot. Pouring oil into gasoline is beneficial in itself, because it preserves better the most worn-out unit - the piston unit. However, if you do not remove it in a timely manner, then you can spoil the same piston with solid carbon particles. Conclusion - in the position "the candle is almost down" pour periodically and not for a long time into the cylinder through the plug hole, for example, acetone.

      To store the scythe, it is rented, should be in the “rod down” position - while the remaining fuel in the crankcase should, in theory, reach the oil seal through the crankshaft bearing separators and lubricate it. With long-term storage, Dumamitsa, an additional spit of oil into the crankcase is more likely to lubricate that oil seal.

      Post-warranty branded repair of the 700 is not advisable - during this period (personally, mine spent two full seasons in full), it completely beats its price, because in the workshop there is a carburetor, magneto for 2000 (50% of the price) and with a one-month warranty. It's easier to buy a new one.

      The benzokos is one of the main tools of the summer resident, used to quickly put the land in order. Owners of private houses also purchase this tool for mowing grass in the backyard. The period of active use of petrol cutters and electric trimmers is in the summer. Before starting operation, the tool is put into working condition: rubbing parts are lubricated, the cutting attachment is changed, a fuel mixture is poured into the tank. If the engine does not start at all or stalls quickly, without gaining a sufficient number of revolutions, then you have to look for the causes of the malfunctions and eliminate the identified malfunctions. To repair a petrol brush with your own hands, you need to understand its structure and the principle of operation of the main units. This information can be found in the instructions for use, which the manufacturer applies to the garden equipment without fail. Check for such a guide when purchasing your chainsaw. The imported tool must be accompanied by instructions written in Russian.

      A long tubular rod is attached to the gearbox of a two-stroke internal combustion engine. A shaft passes inside the rod, which transfers torque from the gasoline engine to the cutting mechanism. The line or knives rotate at 10,000 to 13,000 rpm. There are holes in the protective housing of the gearbox, into which grease is injected with a syringe. For the convenience of using the tool, the manufacturer equips it with a special adjustable shoulder strap.

      A cutting attachment is attached to the brushcutters:

      • The line, which varies in thickness from 1.6 to 3 mm, is located in the trimmer head. The line is subject to wear during mowing. Changing the line is quick and easy in two ways: by winding a line of the same diameter onto a bobbin or by installing a new spool with line already wound.
      • Steel knives with double-sided sharpening for the benzokos for clearing the area from weeds, small bushes, hard grass. Knives differ in shape and the number of cutting surfaces.

      On the U-shaped, D-shaped or T-shaped handle, which is attached to the boom, there are the petrol cutter control levers. The cutting mechanism is protected by a special casing. Household brushcutters are filled with a mixture prepared from gasoline and oil, which is poured into the fuel tank. The device of semi-professional and domestic brushcutters, equipped with a four-time gasoline engine, is slightly different. The filling scheme is also different: oil is poured into the crankcase, and gasoline is poured into the tank.

      The measured piece of fishing line is folded so that one end is 15 cm longer than the second.We put the loop into the slot on the spool and start winding in the direction indicated by the arrow

      If you cannot start the petrol cutter, then the first step is to check the presence of fuel in the tank and its quality. For refueling the tool, it is recommended to use high-quality gasoline purchased at gas stations, the grade of which should not be lower than AI-92. Saving on cheap fuel can lead to a breakdown of the cylinder-piston group, the repair of which can take a third of the cost of the brushcutter itself. It is equally important and correct to prepare the fuel mixture from gasoline and oil. The proportional ratio of these components of the mixture is indicated by the manufacturer in the manual. It is not necessary to prepare the fuel mixture in large volumes, since its properties are lost during long-term storage. Better to use a freshly prepared mixture.

      When preparing the fuel mixture, pour oil into gasoline using a medical syringe, which allows you to accurately observe the required proportion of components

      A dirty fuel filter in the tank can also prevent the brushcutter from operating. Therefore, if problems arise with starting the motor, check the condition of the filter. Replace the filter if necessary. Do not leave the inlet pipe without a fuel filter.

      The air filter also needs to be checked. When contaminated, the part is removed, washed in gasoline in the field and put in place. In the country or at home, the filter can be washed in water using detergents. After that, the filter is rinsed, wrung out and dried. The dried filter is moistened with a small amount of oil used to prepare the fuel mixture. Excess oil is removed by squeezing the filter with your hands. Then the part is installed in place. The removed cover is put back and secured with screws.

      The air filter, washed in a fuel mixture, wrung out and dried, is installed in place in a plastic case and closed with a lid.

      You can see how this procedure is done in more detail in the video:

      If all of the above procedures are carried out, and the engine does not start, then adjust its idle speed by tightening the carburetor screw. In the video posted at the beginning of the article, attention is paid to this issue.

      1. Place the tool on its side with the air filter at the top. This arrangement of the chainsaw ensures that the fuel mixture hits the bottom of the carburetor. The engine will start on the first attempt if you remove the air filter and pour a few drops of the mixture into the carburetor before starting, then reinstall the dismantled parts. The method has been tested in practice.
      2. If the first tip doesn't work, then the problem is most likely in the spark plug. In this case, unscrew the plug and check its functionality, and also dry the combustion chamber. Replace the candle that does not show signs of life with a new one.
      3. If the spark plug is in good working order, the filters are clean and the fuel mixture is fresh, then you can use the universal method of starting the engine. Close the carburetor choke and pull the starter handle once. Then open the throttle and jerk the starter 2-3 more times. Repeat the procedure three to five times. The engine will definitely start.

      Some pull the handle with such force that they have to repair the starter of the petrol cutter with their own hands. This is only possible if the cable breaks or the cable handle breaks. In other cases, it is recommended to replace the starter. This unit is sold assembled.

      • Stop the engine and wait for it to cool down.
      • Disconnect the high voltage wire from the spark plug.
      • Unscrew the part using a special wrench.
      • Inspect the spark plug for replacement. The part changes if it is faulty, heavily soiled, has a crack on the case.
      • Check the electrode gap. Its size should be 0.6 mm.
      • Tighten the new spark plug inserted into the engine with a wrench.
      • Install the high-voltage wire to the center electrode of the spark plug.

      As you can see, there is nothing super complicated in this procedure.

      A new spark plug for a two-stroke internal combustion engine of a gasoline streamer is installed to replace the old part that is out of order

      After starting, the engine may stall if the carburetor is incorrectly tuned or misaligned. What are the signs that you can understand that the reason really lies in this? It is very simple, by the vibrations that will be clearly felt when the mower is running. You can adjust the fuel supply with your own hands by following everything that is written in the operating instructions for the tool.

      The engine may stall due to a clogged fuel valve. The cause is eliminated by cleaning it. If the brushcutter starts up and then suddenly stalls, it means that the fuel supply to the carburetor is difficult. Loosen the carburetor valves to ensure that the correct amount of fuel can flow to it.

      Excessive air intake can also stall the engine. Increase engine revs to allow air bubbles to escape faster from the unit's fuel system. Also, be sure to check the integrity of the fuel intake hose. If you find mechanical damage (cracks, punctures, etc.), replace the part.

      During the period of operation of petrol cutters, monitor the condition of the engine cooling system. The channels in the starter housing and the cylinder fins must always be clean. If you ignore this requirement and continue to operate the brushcutter, you can damage the engine due to overheating.

      Competent care of the gasoline scythe during operation allows you to use it for several seasons in a row without major repairs

      Allow engine to cool before cleaning. Take a soft bristled brush and clean the outside of the dirt. Cleaning of plastic parts is carried out with solvents, including kerosene, or special detergents.

      At the end of the summer season, the brushcutter must be prepared for long-term storage. For this, the fuel mixture is drained from the tank. The engine is then started to use up fuel residues in the carburetor. The entire tool is well cleaned of contamination and goes to "hibernation".

      As you can see, it is possible to repair the faults of a household petrol cutter on your own. It is worth contacting service departments in case of serious breakdowns. In this case, the cost of repairs should be correlated with the price of a new petrol cutter. It may be more appropriate to buy a new instrument.

      Modern technologies and equipment make it possible to produce the best and optimal technical solutions that become effective assistants in the arrangement of a summer cottage or a personal plot. The green lawn and other plantings can grow rapidly, a petrol cutter is used to tidy up the local area and mow the lawns, which is also called a brushcutter or trimmer, a petrol mower.

      Traditional braids are inconvenient and unsafe to use, require a significant investment of time and effort, which will help save gas mowers, combining functionality and practicality in their design. In the photo of the petrol brush, you can see various high-tech devices, which are inherent in a set of operational characteristics, including such parameters as increased productivity and a long service life.

      A convenient and reliable trimmer is a technical device consisting of individual mechanisms, parts and elements that can wear out, become unusable and damaged during intensive use.

      Even with regular technical inspection, maintenance procedures and careful storage, such devices and their individual parts require repair and even replacement, all repair procedures can be performed independently.

      Brief content of the article:

      The easiest way is to give the petrol cutter for repairs, having allocated a certain amount of funds from the family budget, prompt and high-quality repair with your own hands is no less simple and convenient if you want to understand the design of the petrol cutter and fix all the problems.

      

      

      The mass and piece production of trimmers is based on the use of generally accepted technology, a typical design scheme consists of certain elements and parts, it is important to know them when carrying out independent repair work:

      • top part. The basis of the entire structure, where all important elements are collected, such as a starter, a carburetor and a petrol cutter engine;
      • middle part. A hollow rod, inside it is a cable that connects the motor and the gearbox, which drives the cutting line. In this part, there are fasteners for distributing the weight of the entire structure and a belt for fixing the trimmer on the belt of a person using the trimmer for its intended purpose;
      • Bottom part. It houses the gearbox and cutting elements, which are hidden under a practical cover to protect the user. The casing provides an increased level of safety, preventing large fractions of debris, stones and glass from entering a person while working with a petrol cutter.

      

      Knowing exactly the internal structure and the principle of operation of the trimmer, you can independently carry out repair measures for the structure or replace individual components that have become unusable, using the repair instructions.

      The most common and common failures of the unit that need to be corrected on their own include the following problems:

      • engine malfunction, due to which the brushcutter does not start and does not work;
      • increased vibration of the brushcutter bar, which complicates its intended use;
      • increased overheating of the gearbox, its accelerated heating during operation;
      • slow and weak functioning of the cutting line at insufficient speed;
      • clogging of the starter grille, causing overheating of the engine and its refusal to work;
      • fast and frequent clogging of the carburetor due to the use of low-quality fuel;
      • clogging of the air filter due to non-observance of the measures for the care of the device.

      

      

      All these problems can lead to the fact that the device will lose its working capacity. Before ordering the necessary spare parts for the mowing, a visual inspection and diagnostics of the device should be carried out.

      Particular attention should be paid to individual spare parts and units of the device, to check them you will not have to contact a professional master, a set of diagnostic measures will help you to identify the consequence of a loss of performance with your own hands.

      If the trimmer motor does not start or stalls immediately after starting, when the gearbox overheats or during the operation of the device, extraneous noises are heard and vibration is clearly felt, it is important to visually inspect and identify a non-working unit.

      To optimize the preparatory measures before repairs, you should carry out a simple diagnosis and check step by step:

      • the presence of fuel in the tank and lubrication in the main units;
      • serviceability of the spark plug and its performance;
      • the cleanliness of the fuel and air filter of the brushcutter;
      • clogging of the outlet channel and breather of the device;
      • the quality of the fuels and lubricants used.

      To determine the functional performance of the petrol-cutter's ignition, it is necessary to determine whether the spark plug is working by testing the appearance of a spark when it comes into contact with the body of the functional device.

      The spark plug itself can be replaced with a new one, having previously dried the candle channel, if necessary, the old element is also dried, cleaned with special devices and returned to its place.

      In the process of inspecting the carburetor, it is worth paying attention to the possible leakage of the fuel used; in order to identify problems with the carburetor, the following measures must be taken:

      • purging the fuel hose to eliminate possible blockage of the element;
      • checking and replacing the gasket between the engine and the carburetor;
      • determination of tightness and maintenance of constant pressure in the unit.

      

      

      If necessary, you can personally disassemble and thoroughly clean the unit using gasoline, the jet and channels are cleaned using compressed air.

      

      The gearbox transmits torque from the motor shaft to the cutting tool, its gears during operation must be absolutely clean and always lubricated with special grease.

      • 

      

      Carrying out a technical inspection on your own once a season will allow you to get rid of the need to repair the gearbox or replace it, with the purchase of an expensive new unit.

      

      The starter is necessary to bring the trimmer into working condition, its diagnostics consists in checking the tension of the starter cord connected to the teeth of the starter coil, which are often destroyed during an abrupt start.

      

      An inoperative starter in a petrol cutter cannot be repaired; it must be replaced with a working unit as part of a mandatory technical inspection or a set of repair measures.

      

      Cutting elements require special attention and care, which must always be cleaned of dirt and cut grass after use. Regular inspection and thorough preparation of the device for operation will help to avoid costly and time-consuming repairs, and always be confident in the performance of the petrol brush.

      Good time of the day, dear friends!

      Today I want to share useful information about trimmer repair, which was kindly provided to me by our reader Yuri. With his consent, I am publishing this, in my opinion, very useful information.

      I will share how I repaired the MTD-600 trimmer (ignition problems), maybe someone will come in handy.

      At first, nothing is clear, the trimmer simply does not start, does not even sneeze.

      1. I checked the compression (to exclude mechanical breakdown in the cylinder, rings, connecting rod, etc.) - after a couple of jerks, the compressor shows 10 bar - this is quite enough, the cylinder-piston-rings are in order.

      .
      2. Gasoline is supplied through the carburetor - the plug is wet and the top of the piston is wet.

      .
      3. The candle is clean, the gap is 0.6 mm. When scrolling, there is a spark - the twisted candle (its threaded skirt) is temporarily connected with a wire to the cylinder and we turn the starter - everything is in order.

      .
      4. There is compression, there is gasoline, there is a spark, but it does not start, which means there are problems with the ignition (ignition timing).But the ignition moment on trimmers / chainsaws, on such two-strokes is not regulated! Therefore, we disassemble the trimmer - we take the engine away from the shaft with the starter. Magneto opens - a coil with two pins-contacts and with two "cheeks" of the core, which at some point are closed by a magnet built into the flywheel, which the starter clings to when scrolling. It was found that this short circuit (it can be seen - this is the alignment of both ends of the magneto core with such well-defined areas of the magnet in the flywheel, the gap there is a fraction of a millimeter, while in other positions of the flywheel above the magneto it remains a few millimeters) does not coincide with the TDC ( top dead center) of the piston (this point is easy to find by turning the shaft, observing the piston into the hole in which the plug is turned out).

      Here comes the breakdown! Magneto should close somewhere near the "VMT", and it closes when the piston went down somewhere! We unscrew the nut that presses the flywheel to the tapered shaft. It is found: the pin is cut off, which enters the grooves on the shaft cone on the outside and on the inner cone of the flywheel and which rigidly mates them in one position. The flywheel "cranked". Most likely, someone with too much foolishness jerked the starter, so he tore off the flywheel, knocking down the ignition (the American trimmer should be easy to start by a child, power is not needed, but there are tractor drivers with experience in starting a diesel launcher, for them this technique will be rather delicate) ...

      .
      5. If there is no standard pin, then you need to make it yourself: a small plate bent with the letter “U” so that with its “horns” it fits into two grooves in the flywheel, and its curved part into a wide groove on the tapered shaft. Empirically, its size is selected so that the flywheel lowers on the shaft and is securely fixed.

      We check the coincidence of the closure of the magneto and "VMT", tighten the flywheel nut, assemble the trimmer, start according to the instructions.

      Many thanks to Yuri for such useful information!

      Any complex technical equipment has a limited working life. And with an increase in the intensity of its operation, the risk of its failure increases. However, it is within the power of each owner to reduce the number of such emergencies if the rules for use and maintenance recommended by the manufacturer are followed exactly. In any case, you should be prepared for the fact that at a certain period, malfunctions in the operation of the device will still arise. Malfunctions that can occur in the trimmer operation can be of a different nature. However, in some cases it is quite possible to repair the trimmer on your own.

      

      Equipment that operates on mains differs from similar devices that provide a built-in power drive in that it has a simpler design. The main elements of a trimmer are the following:
      • mechanical part that transmits torque to the trimmer head;
      • electric motor;
      • power cable.

      In this case, all the problems that may arise with this equipment can be presented in the form of the following groups.

      Main function when using the device assigned to the trimmer head, in which the cutting surface is made of fishing line. In most cases, the device fails due to problems with its supply.

      • If the line is used up, it is necessary, following the instructions of the instructions, to wind a new one.
      • Line entanglement may be one reason for work stoppages. In a similar situation you need to unwind it and insert a new bobbin if it shows signs of damage.
      • Also, the trimmer may fail due to stuck nylon thread, which may be due to overheating of the device during its long-term use. This problem is solved by rewinding the line.
      • Malfunctions can be directly related to the coil: for example, the bottom of it may fall off. Repair in this case will be reduced to replacing it or creating a new bottom with your own hands. Having chosen the last option, it is necessary to prepare a piece of PCB or a bolt with a nut.
      • In some cases, the coil may not show signs of damage, the motor may also be fine, but the head does not rotate. In a similar situation, you should look at the drive shaft. If the fear of its breakage is confirmed, then the device must be handed over to a service center.

      If the failure of the gasoline trimmer is associated with malfunctions in the mechanical part, then the repair technology will for the most part repeat the work carried out in relation to electric models.

      

      

      To carry out repairs to electric trimmers, you must prepare the appropriate tools:
      • indicator screwdriver;
      • multimeter;
      • blowtorch.

      It is rather difficult to find out by visual inspection what caused the malfunction; in most cases, only the most obvious malfunctions can be identified by eye.

      Regardless of the nature of the malfunction, this in any case leads to the termination of the engine.
