Trimmer for grass ignition how to configure why

Often, owners of gasoline cos are faced with the fact that ignition does not work on their technique. In most cases, the problem is really in this node. To fix it, you need to adjust the ignition on the trimmer. But at the same time, there are frequent cases that the ignition coil is working and a breakdown should be sought elsewhere. The ignition system is arranged equally on four.Stroke and two.Stroke internal combustion engines, therefore, the correction of the malfunctions of this node is carried out in a similar way. In addition, the technique of different brands has an almost identical design of this most important component of the tool, which means that the process of adjustment will be identical for both the trimmers “Soyuz” or “Prostr”, and for Huter or samples of other brands.

If the owner of the lawn mower wants to establish the operation of the ignition system on his own, he should understand the principle of operation of this unit. In the internal combustion engine, it consists of a flywheel and magneto (coils). In turn, the flywheel includes a impeller that performs the function of cooling the motor and a number of permanent magnets.

Operating principle

When the flywheel rotates, an electric current is generated in Magneto, which creates a spark on the spark plug at the moment when magnets pass under the coil.

Typical malfunctions

Before starting the ignition of the trimmer for the grass, you need to cut off other probable causes of breakdown and make sure that the problem is really in this node. For this, it is necessary to carry out a number of actions in the following sequence:

  • Inspect the ignition coil body for damage and defects;
  • Make sure that there are no pollution on all nodes and elements conducting current;
  • Check the integrity and isolation of the wiring, contacts, the strength of the fastening, the presence of rust at the joints;
  • Inspect the candle cap, as it regularly breaks away from the high.Voltage wire, and they try to restore it manually, and any unreliable connection lowers the power of the electric arc of the candle;
  • Check the candle, since the quality of modern gasoline very quickly disables this part, but there is another possible problem. The candle is wet;
  • Make sure the circuit switch is working.

By excluding all possible malfunctions, you can proceed to adjust the ignition of the coil.

When you need adjustment

It is necessary to adjust the ignition system so that the fuel is ignited at the right time in the combustion chamber.

Important! Когда поршень сжимает горючее и практически достигает мертвой точки сверху, в свече возникает искра. Further, when it passes the maximum upper point, the fuel is lit up, as a result of the explosion, energy forms and directs the piston down.

If the flywheel is shifted to the shaft relative to its original position, the fuel is ignited faster than the piston overcomes the upper dead point. As a result of this, the piston moves back, and the crankshaft rotates in the opposite direction. You can determine the early fire of the fuel by a broken launch cord, a broken starter node or other breakdowns.

Sometimes ignition is late. The piston compresses the irreparable fuel, and then goes down, and only then the spark forms. As a result, the engine either does not work or its power is reduced, and the speed is gaining much slower.

Typically, a flywheel with magnets is installed in an ideal position, as if coordinated with the operation of the piston, and in order to avoid displacement, it is carefully fixed. This allows us to say that an incorrect installation of a part is impossible. But if the shift of the flywheel is a confirmed fact, then it is a failure or accident. Thus, the installation of the moment of the ignition is not required, since problems with early or late ignition of fuel happen very rarely.

configure, ignition, trimmer, setting, system

Important! It is very simple to regulate the ignition system. There is no need to calculate the ignition angle angle. The maximum that you need to do is to properly set the gap between the flywheel and the reel.

The gap between the ignition coil and the flywheel of the chainsaw

DIS engines are installed not only on cars or bikes. They are vastly used in different tools, for example, such as a chainsaw or a trimmer for grass. In the event of their malfunction, disgusting launch, it is often enough to establish a sure gap between the flywheel and the ignition coil.

Ignition module

The inoperability of SZ chainsaws is a common reason due to which the tool engine does not start. In most cases, it is recommended to start a search for a problem specifically from here.

  • First painstakingly check the spark plug, carefully throwing the armored wire from the head and twisting the candle from the nest using a special key;
  • 2nd-this is a check of the sparking by twitching the starter when planted on a candle cap of the armor pipeline;
  • Checking the gap is the main theme of our article (more below).

So, the malfunction of the spark plug will obviously testify to its sputum. A wet sparking device for ignition of the fuel-air consistency states that in the system of fuel is an excess, a carburetor is incorrectly configured or there are problems in SZ.

The candle is checked only after drying. T.E., It needs to be well cleaned with a napkin, drain the insides of the internal combustion engine, clog the feed, and then start a starter several times so that excesses of the combustible consistency are released.

Then the spark device is put in place, and all the Ponova is checked.

In general, the spark device can tell almost everything about the entire ignition system. If a dark carbon monoxide is observed on the candle, this indicates violations in the communications of gasoline consistency. Here, either the ratio of gasoline and oil was violated, or the carburetor is required to reconfigure. In some cases, this happens due to poor oil.

A dirty candle is cleaned of a dark carbon fiber with a needle or any other sharp object. Then the electrode is cleaned with the sandpaper (zero) until the iron radiance appears. The spark device is fraught in place, everything is checked.

Subsequent step: checking sparking. The skirt of the spark device is brought to the cylinder, the starter starts. If a bluish spark slips at a distance of 2-3 mm, everything is fine. The sparking distance of 0.5-1 mm is already considered as a malfunction. There may not be sparks at all, and this is also a big inconsistent. Maybe the case is in the cliff of the wire.

And so we approached the topic of our article. The chainsaw may not be launched due to the disorder between the ignition and the magnet magnet magneto. This very gap should be within the boundaries of 0.2 mm. It is checked to pain simply: a special laying is placed between the flywheel and Babina. If it comes normally, not very free and tight, then the gap is ordinary.

The flywheel himself drank is round, and checking the clearance by ordinary probe is impossible. Gap It would be more qualified to put it according to a special show, but it does not always be possible to purchase. Well, to take a template that is expensive, not everyone can allow for 1-rack implementation.

But in return for the foreign template, you can use a cut strip from a plastic container for 1-2 liters of juice.

Ignition adjustment algorithm

The ignition on the trimmer is adjusted quite simply.

    Remove the casing from the engine by unscrewing all the bolts holding it. For example, on the Patriot gasoline (Patriot) PT 2540, to remove the casing, you need to unscrew the air filter housing, and remove it with a flat screwdriver from the latches. After that, the plastic case will easily remove.

Lingering on a walk.Behind tractor. Adjustment, repair, malfunctions

One of the main nodes in the design of the walk.Behind tractor is the ignition system. She is responsible for the formation of a spark required for instant ignition of the fuel mixture.

The ignition system of a modern walk.Behind tract has a fairly simple design, which allows you to configure or repair the node with your own hands.

However, for this it is necessary to observe the correct procedure, otherwise there will be a great risk of damage to the details of the system.

How to set the ignition on a walk.Behind tractor. An algorithm for execution

From time to time, the one.Axic tractor needs to adjust the ignition system. Untimely setting up this node will lead to the accelerated wear of other, no less important mechanisms of agricultural machine. In order to be able to independently adjust the ignition system on the diesel walk.Behind tract and its gasoline analogue, you need to study the design diagrams of this node.

A properly.Configured he ignition system of a walk.Behind tractor can create a spark in the right place and at a suitable moment for this. At the same time, Magneto’s cover is responsible for the distribution of the resulting spark, and its lower part for interruption. In order for the ignition system to work precisely on this principle, it should be adjusted.

The ignition installation is performed in the following order:

  • First you need to check the work of the flywheel available in the engine until the contacts opened inside the magneto open;
  • After that, it is necessary to measure the distance between the “hardware” and “hammer” built into the ignition system;
  • Then you need to turn the flywheel until the moment the piston is compressed;
  • As soon as the flywheel reaches the top of the top, it needs to be turned again. As a result of this, a one.Time knock will be heard, indicating the operation of the overtaking coupling available in the design;
  • After that, the flywheel will need to turn against the course of the time stroke so that the second mark on it comes together with a mark located on the case;
  • The next step will be the adjustment of the distance between the contactor contact and the fist located nearby. The minimum for good operation of the ignition system will be a gap between the parts of 0.25 mm, and the maximum. 0.35 mm;
  • At the end, it remains to fix the built.In fist with a special screw, which is located on top. About how to correctly configure the ignition system on the walk.Behind tract will tell a video.

The performed ignition adjustment will accelerate the launch of the motor block and make it smoother, which will lead to a slowdown in the wear of the piston group and other important elements of the agricultural machine motor.

Lack of sparks

This is one of the typical malfunctions of the ignition system of the walk.Behind tractor. The most common reasons for this are the formation of a pile on a spark plug or its breakdown. In this case, you should twist the candle and carefully inspect its lateral and central electrodes.

If the spark plug is covered with a soil formed as a result of pouring the part by the fuel mixture, then the candle will be not enough alone. It will be necessary to check the tubes of the fuel system of the motor block for leaks.

Examples of cases with highly planted fuel candle are clearly visible in the photo.

If a spark is gone, then in any case you will need to carefully clean the candle. To do this, it is best to heat it above the gas burner, and then scrape off the dried fuel from the surface.

After cleaning the part on its upper part, the tip should be put on and bring the motor block to the body body. The candle must be held so that its electrode is about 1 millimeter from the engine housing.

At the same time, try to launch a motoblock motor with the second hand.

If the candle is completely serviceable, then a spark is formed in its lower part, which will jump out and hit the motor body. If this does not happen, then you need to inspect the distance between the side and central electrodes.

Between them should be placed a blade, and if it enters tightly between two electrodes, then the gap has the optimal dimensions. If the blade hangs, then you will need to knock on any hard object on the back of the central electrode.

As a result of this, he shift, after which you need to try again to start the engine engine.

Self.Check of magneto for a walk.Behind tractor

Another important element of the ignition system of the walk.Behind tractor is magneto. In case of malfunction of the node, it also lends itself to a careful inspection for performance. Checking the Magneto Motobobok is quite simple.

To do this, it is necessary to clean the candle from the carbar accumulated on its surface and make sure of its serviceability. Then a cap with a good drive is put on the candle.

Further, the lower part of the candle must be brought to the Magneto body, and start rotating the flywheel located in the motor with your fingers.

If the spark in Magneto did not appear on the uniform tractor, then the element is out of order. In this case, it will be necessary to replace the magneto of the ignition system of the walk.Behind tractor in order to prevent wear of other unit mechanisms.

How to check the ignition coil on a walk.Behind tract?

Check, and, if necessary, repair the ignition coil, follows the same principle as the Magneto Motobobok.

The following factors indicate the signs that the ignition coil of the walk.Behind tract is out of order:

  • Weak spark or its complete absence;
  • The presence of the smell of molten plastic in the area where the ignition coil is installed;
  • The appearance of crackling sound when trying to start a single tractor.

In any of these cases, you will need to carefully examine the ignition coil of the walk.Behind tractor. To do this, it is best to completely dismantle it. For this purpose, you should first unscrew the fasteners and remove the upper cover of the ignition system body. Then you need to turn off the high.Voltage wire and, gently prying the coil, extract it from the case.

After that, you need to carefully examine the part on the presence of traces of melting. If black spots are visible on the coil, then most likely the current it created did not get to the candle, as a result of which the ignition reel itself succumbed to the voltage. Especially often, farmers are faced with this problem, in whose walk.Ashes, a contactless ignition is installed.

We often encounter situations where users of the device have a faulty ignition. Often this really turns out to be faulty, but often the ignition coil has nothing to do with the abloancy of the tool. Below are described actions to check the performance of the ignition coil.

Assessment of the current state of coil.

Before work with the ignition coil, it is worth checking the performance of the entire circuit. Follow these actions:

  • Visually assess the absence of cracks and visible defects on the coil body
  • Pollution of conductive elements and nodes
  • Performance and isolation of high.Voltage wires, contacts of wires, reliability of their attachment, lack of rust in places of fastening
  • Check the condition of the candle cover: it is often disconnected from the high.Voltage wire and tries to restore it with the help of “impromptu” methods. Remember: any “snot” in this place reduces the quality of the electric arc of the candle
  • Check the serviceability of the candle. The quality of our gasoline does not allow a candle to “live long”,
  • Check the operability of the circuit breaker. This is especially important for Chinese saw and trimmers.

The meaning of these actions is to exclude all elements of the scheme from the list of possible failures, with the exception of the coil. If everything is in order, we move on.

Why is the ignition adjustment

In some cases, when the engine does not start, the ignition adjustment will be required. Of course, first you need to check the serviceability of a candle and a high.Voltage cable with a cap.

It is necessary to adjust the ignition on a two.Stroke engine in order to ensure timely ignition of fuel in the engine combustion chamber. Below is a scheme from which you can understand the principle of operation of the internal combustion engine.

The spark in the candle should appear at the time of compression of the fuel with a piston, when it does not reach the upper dead point (VMT) at least a little. Когда поршень проходит ВМТ, происходит возгорание топливной смеси, в результате чего поршень под действием энергии взрыва уходит вниз.

configure, ignition, trimmer, setting, system

Therefore, if for some reason (mainly this is due to the shift of the flywheel to the shaft regarding its original position), the fuel fire occurs earlier than the piston passes the vehicle, then it returns back, and the crankshaft scrolls in the opposite direction. Such a movement can damage the starter knot, cut off the launch cord, etc.D. In this case, an early ignition of fuel occurs.

There may also be a later ignition on the trimmer: the piston after compression of the fuel, which does not ignite, goes down, and at that moment a spark appears. In this case, the engine will either not start or significantly lose power and will be poorly gaining momentum.

But such problems with early or late ignition on two.Stroke ICE are quite rare, since the flywheel with magnets is already established in the correct position, which is perfectly synchronized with the movement of the piston. In addition, the flywheel is fixed on the shaft using a key and nut. Therefore, the wrong installation of the part is excluded.

Ignition adjustment algorithm

The ignition on the trimmer is adjusted quite simply.

    Remove the casing from the engine by unscrewing all the bolts holding it. For example, on the Patriot gasoline (Patriot) PT 2540, to remove the casing, you need to unscrew the air filter housing, and remove it with a flat screwdriver from the latches.
