How is the gas tank of the trimmer for grass inside.

Repair of plastic gas tank, independently eliminate leak

The leakage of the gas tank is a rare phenomenon, but such a problem can happen to each. In general, plastic gas tank is eternal (namely plastic gas tanks are installed on most existing cars), as it is protected from corroding gasoline. However, he is threatened with other problems. sandblast and any mechanical damage. Even if the gas tank leaked, this is not a reason to throw it out, because it can be quite budgetary to repair it.

Structurally, gas tanks are actually not protected by external damage, in contrast, from foreign analogues. Often small fractions of gravel, crushed stone, asphalt, bouncing from the rear wheels evenly ruin the shell of paint and primer, bringing incorrigible harm to the metal. A few days later, the metal begins to rust. The driver begins to notice a fuel leak.

How to seal a gas tank? Now there are two brand options:

  • The introduction of cool welding for sealing cracks and holes;
  • Epoxy glue or still called fiberglass. It is better to take two.component.

Device and operation of the fuel supply system of a benzotrimmer

To correctly determine the cause of the absence of gasoline in the engine cylinder, it is necessary to study the device and operation of the fuel supply system of such motors.

The gas tank is noticeably lower than the engine, so the fuel comes in two ways:

To start a motorcycle, which has not been operated for some time, you must first pump up gasoline so that it fills the pipeline and carburetor, thereby forming a closed system.

The primer is made in the form of a rubber button, which is pressed with a finger, and the unidirectional movement of gasoline provides a valve.

When the operator pumped up the fuel, then performed the rest of the preparatory measures, which we talked about here, and the engine earned, the second way to supply fuel is turned on. When the piston moves down during the intake of the inlet, in the combustion chamber of the lawn mower there appears discharge, which sucks atmospheric air through the air filter.

The basis of the carburetor is the Venturi tube operating on the same principle as the popular spray cleaner and ordinary glass jar in the USSR.

The passing flow of air captivates droplets of fuel, and the ratio of air and gasoline in the finished mixture depends on the diameter of the nozzle limiting the flow of combustible fluid.

The faster the engine shaft is spinning, the stronger the operator presses the gas trigger, the higher the speed of the air flow passing by the nozzle, which means that more fuel enters the engine per unit of time.

Reasons for the cessation of fuel intake

These are the reasons why the fuel does not enter the cylinder:

  • The gasoline ended in the tank;
  • When starting the engine, the fuel was not pumped with a primer;
  • Primer faulty;
  • Due to the improper inclination, the fuel system was ripening;
  • The fuel system is leaky;
  • The ventilation hole of the gas tank clogged;
  • Carburetor scored with dirty fuel.

Gasoline ended

The first sign that gasoline in the tank is over is the unstable operation of the motor, which drops for several seconds, then briefly raises the moment, sometimes “sneezes”, then stalls and does not start anymore.

It is not difficult to determine the reason. it is enough to look at the fuel tank. it is transparent, so the level of fuel is always visible.

Most often, inexperienced trimmers are found with such a reason, who do not know how to determine the working time at one gas station. This does not bring any harm to the engine of the trimmer for grass, but after refueling the tank with fuel, it is necessary to pump fuel according to the system, but if it is added to gasoline before it ends, you can do without pumping.

When starting the engine, the fuel was not pumped up with a primer

This reason is also characteristic of inexperienced owners of motorcycle, which have not yet brought the performance of this action to the level of reflex.

In addition to anxiety about the possible breakdown of the apparatus, neglect of the pumping of fuel will not give any negative consequences, but excessive experiences can lead to a breakdown of technology.

For example, an inexperienced user who has tried to launch the engine and failed to do this, begins to unconsciously apply too much effort to the starter cable, forgetting to choose a free move, which can lead to a breakdown of the mechanism.

Primemer malfunction

Most often, the cause of such a malfunction is a dependent valve that does not block the fuel movement in the opposite direction when pressing the primer button.

To reliably determine the cause without disassembling the device, pull the hand starter cable 30-50 times with a mandatory selection of free move, but without breakthrough. If this leads at least to the “sneezing” of the engine, then the problem is really in the primer, so the trimmer requires repairs.

Due to improper inclination, the fuel system was ill of

The fuel system caused by incorrect inclination is as follows:

  • a change in the position of the drive shaft changes the angle of inclination of the fuel tank;
  • Gasoline, following the power of attraction, strives down and is aloof from the suction tube;
  • The air through the absorption tube enters the fuel system and after the production of a fuel located in the tube and carburetor, the engine stops receiving gasoline;
  • After absorption of even a small portion of air created by the discharge engine is no longer enough to effective fuel promotion through the system, so even returning to the normal angle of inclination everything leads to stopping the motor.

The fuel system is undergoing

This is the most dangerous reason, because in addition to a violation of the supply of gasoline to the engine, it can lead to ignition of the arising fuel, which is fraught with serious burns or fire.

Most often, the source of the problem becomes either a leaking seal, or a damaged or jumped hose.

Any of the defects leads to the fuel system, and the main manifestation is gasoline drops and a strong smell.

The ventilation tube of the gas tank clogged

Despite the tightness of the fuel system, the gas tank provides a hole for supplying air that compensates the spent fuel. On the vast majority of trimmers, a hose passes through the ventilation hole, this protects the fuel from dust and dirt.

The speed of air through the tube is small, so the dust or dirt does not suck into it, so the fuel is not polluted. If this tube is clogged, then the discharge that occurs in the tank compensates for the discharge created by the piston, so the fuel movement stops.

How to Replace the Fuel Tank on a Ryobi String Trimmer

Carburetor scored with dirty fuel

Poor.quality gasoline with large ms and various dirt can score the channels of the carburetor and disrupt the operation of all fuel supply systems.

On different operating modes, the motor requires a fuel mixture with a certain proportion of air and gasoline, if the proportions change, the operation of the motor is disturbed.

A working carburetor instantly responds to a change in the operating mode of the power unit, including increasing the load, adjusting the amount of fuel, but clogging deprives it of this ability. The result can be a strong drop in power and revolutions, and a complete stop of the motor.

Launcher of the starter and gearbox

The gearbox conveys the rotational moment from the engine shaft to the cutting tool, its gears during operation should be absolutely clean and necessarily lubricated with special lubricant.

Conducting a technical inspection on their own once a season will get rid of the need to carry out the repair of the gearbox or its replacement, with the acquisition of an expensive new node.

The starter is necessary to bring a trimmer for grass to working condition, its diagnosis is to check the tension of the lace of the starter coil with the teeth of the coil, which are often destroyed at a sharp launch.

A non.working starter in a benzocos is not subject to repair, it must be replaced with a working unit, as part of a mandatory inspection or a set of repair measures.

Separate attention and care require cutting elements that must always be cleaned of dirt and mowed grass after operation. Regular inspection and thorough preparation of the device for work will help to avoid expensive and costly repair time, always be sure of the operation of the lawn mower.

How to choose a gasoline trimmer for grass?

The tool has an unlimited mobility and a powerful engine that expands the tool for using the tool. Those who first decided to purchase a similar tool are interested in which is better to choose a gasoline trimmer for grass. The first thing that is important to consider is the presence of a service center within the reach of the service and the ability to purchase spare parts. When choosing, pay attention to the following points:

  • engine power;
  • type of cutting tool;
  • type of bar and handles;
  • belt equipment;
  • mowing width;
  • volume of gas tank;
  • The number of additional nozzles.

Gasinzin trimmer nozzles for grass

The device is so universal that it can work in different positions. Garden gasoline trimmer for grass can be equipped with the following nozzles:

  • Drill. Engine power creates a huge spinning moment in the drill.
  • Wheel wheels. Help reduce the friction of the tool about the surface, which facilitates the work and improves its quality. Gasoline gasoline self.propelled vehicle is endowed with qualities that reduce the wear of parts.
  • Bitch. The work uses the principle of hacksaw. You can cut branches at a height of about 2.5 m.
  • Gardening scissors. Help to cut a hedge and curly bushes. The models have a different length of the bar.
  • Aerator of the lawn. Used to saturate the surface of the soil by air by piercing it. The destruction of crusts on the beds is destroyed in the same way.
  • The nozzle is cultivator trimmer for grass gasoline. Used for loosening soil.
  • Water pump. Helps to supply water or pump out liquid.
  • Brush and roller. Used to sweep the tracks and lawns.
  • Snowman. Helps remove snow from the selected surface.

Rating of gasoline trimmers

Among the variety of models, an inexperienced person can be confused and mistaken with the choice. To avoid this, you need not only to know the main characteristics, but also to be familiar with the most popular options. To date, the rating of the best models is as follows:

    STIHL FS38. Super light model for cutting low grass. The gasoline trimmer works for Stihl grass only with a fishing line.

How to use a gasoline trimmer?

The operation of the device is simple, however, it is still endowed with a certain specificity. To avoid problems, it is recommended to get acquainted with the instructions before starting work. Initially the preparation and verification of the condition of all parts is carried out. It is important that there is a lubricant in the gearbox, and the oil in the crankcase. After filling the fuel tank, they try to start a trimmer for the grass. Before starting the haircut, the tool should work out a couple of minutes at idle speed. General principles of the work of a hand gasoline-trimmer for grass:

  • The processing of the site is carried out from right to left. Make 1-2 waves with a gradual movement forward 30 cm.
  • Using a fishing line for a trimmer as a cutting device, capture is chosen empirically.
  • A large site is recommended to mow squares. The grass is removed around the perimeter, and then the movements of the spiral to the center are continued.
  • For a maximum cut, the cutting plane must be kept at an angle of 30º, the tip of the fishing line should touch the ground.
  • High grass is mowed in both directions.
  • The slope is processed in such a way that the peak is to the right of the operator. Movements are carried out in strips, each time returning to the starting point.
  • Speasing branches on a tree or shrub, the protective casing is close to the barrel, slightly tilting the head of the tool to the ground. Movements are carried out from left to right.

The frequency of replacing the candle

Despite the fact that spare parts for the lawn mower are enough to purchase in any specialized store, the owner should have an understanding at what point to change them in the tool most correctly.

Before you go for a new part, it is necessary to disassemble the motor and figure out whether the replacement is necessary or it will be enough to clean it. For this, first of all, there is an instruction for the repair of this tool.

Often, a lawn mower may not work due to the fact that a candle was not changed. But do not immediately rush to change it, first it is quite well cleaned, since the ingress of dirt in many cases leads to various errors, so it is extremely important to remove it in a timely manner.

In addition, after after cleaning, the whole structure will become more visible, which means it will be noticeable if the case is in the departed contact on the connecting wire. Often the problems of candles arising from the candles are mechanical in nature.

How to clean and store a tool?

During the operation of the lawn mower, monitor the state of the engine cooling system. The channels available in the starter housing, as well as the cylinder ribs, should always be clean. If you ignore this requirement and continue to operate the motorcycle, then you can disable the engine due to overheating.

Competent care of gasoline scythe during operation allows you to use it for several seasons in a row without serious repair

Before cleaning, let the engine cool down. Take a brush with a soft pile and clean the outer surface from dirt. Cleaning plastic parts is carried out by solvents, including kerosene, or special detergents.

After the summer season, the lawn mower should be prepared for long.term storage. To do this, the fuel mixture is drained from the tank. Then the engine is launched in order to develop fuel residues in a carburetor. The entire tool is well cleaned of pollution and sent to “hibernation”.

As you can see, it is possible to repair the malfunctions of the household lawn mowed on their own. Service services should be contacted in case of serious breakdowns. In this case, the cost of repairs with the price of a new lawn mower should be correlated. Perhaps it will be more advisable to buy a new tool.

What is a sapun and why it is needed on a trimmer

The fact of the trimmer is, and why it is intended, far from many experienced kosari and instrument owners know. What is it, and how the detail affects the work of the lawn mower, it’s time to figure it out. Before you understand the question of what is called a benzokos as a benzocosa, it should be noted that this part has a direct impact on the launch of the tool engine.

The cabin is called the valve that passes the air in one direction. This part is called a check valve, through which the pressure in a closed container occurs. This tank on a gas tank is a fuel tank. Why do you need to balance the pressure in the tank of the lawn mower, and how the check valve affects the operation of the tool engine?

To understand the purpose of the check valve on a gas station, we will briefly consider the features of fuel supply to the carburetor.

  • The fuel poured into the tank is sucked into the carburetor during engine operation. For this, the tank has a hose that is connected to a carburetor
  • The membrane, which, by creating a vacuum, absorbs its absorption, is responsible for the pumping of the fuel from the tank to the carburetor
  • When operating the engine, a gradual devastation of the tank occurs, and since the tank is a completely tight container, in the process of reducing the fuel, a vacuum or vacuum is created
  • The higher the vacuum (grows with a decrease in the amount of fuel in the tank), the more difficult it is for the carburetor to pump fuel
  • To eliminate the effect of the vacuum in the gas mushroom tank, a check valve is used, which passes the air in one direction, and does not allow fuel to flow out

The sapun is aligned with the pressure of the trimmer for the grass in the gas tank, and if this part is malfunction, the engine starts up. This difficulty is that the carburetor membrane simply does not have the opportunity to suck fuel due to the vacuum formed inside the container. The check valve works as follows:

  • When creating pressure inside the tank, air leaks occurs, thereby the vacuum decreases
  • Air leakage into the tank when the chainsaw is operating excludes the flow of the fuel mixture from the tank

The components of the fuel system of the chainsaw

Having made a superficial acquaintance with the system and its device, we will consider each of its elements with all the attention to the nuances. How diverse are the forms of the same details in various models of chainsaws, and how they can be installed. Detailed features of the components of the fuel system, with visual photos, then.

The tank of the chainsaw

In most models, fuel storage containers are built into the housing and are a monolithic structure with a handle. Replacing such a tank when burning or mechanical damage requires a complete recovery of gas levers and air damper (in addition to hoses). There are systems that seem to be divided at first glance (for example, on the STIHL MS 440), however, the capacity is also intended with the body, and is not sold separately from the handle.

In addition to the chainsaw case, the fuel tank can be located in the crankcase (for example, Partner 351). In this case, the replacement process in case of damage is longer and time.consuming, since it requires disconnecting almost all of the tool components, including the engine. Fortunately, such designs are not always monolith and there are tools where fuel and oil tanks can be removed (Stihl MS 180), significantly facilitating the repair.

Fuel filter

A fairly important and popular consumable that provides protection of the carburetor and engine from pollution and premature breakdown. By type of performance, there are 2 varieties of filters: in a plastic case and in a metal. Nylon (in plastic Chinese elements), felt (in all types of buildings), cortex (in plastic) and foamed polymer (in metal) can be used as a purifying material.

Regardless of the material of manufacture, each fuel filter for the chainsaw has a weighting agent, directing it into the lowest part of the tank when tilting the saw.

The highest degree of protection against small particles provides foamed polymer and cortex. The felt of felt is no less reliable, but quickly clogs. Nylon nets are categorically not suitable for such purposes, therefore, having purchased a Chinese saw with such equipment, it is better to immediately change it to one of the above. The replacement should have an identical diameter of the fitting, which can be 3.5, 4.5 and 5.5 mm.

Fuel hose

The most flexible link in the system that performs the transfer of fuel from the tank to the carburetor and primer (if any). In budget variations of execution, it is made of silicone, and is equipped with a sealant in the form of a sleeve, or does not have it at all and simply enters the hole in the tank tightly. Better quality hoses are made of dense gas.resistant rubber, and in the role of sealing contact, they have special ledges pressed to Baku on both sides.

Of course, according to the duration of the service, a special rubber fuel hose for a chainsaw withstands a longer service life before starting to dry and crack.

There is only one fuel terepine in the classic motorcycle system connected to the input fitting of the carburetor. In the presence of a manual pump (primer), the number of hoses increases to 3x, where the first plays the main role, the second connects the carburetor and primer, and the third removes excess fuel from the primer back to the tank.

Climbing valve (sapun) chainsaw

Small devices, but impressive significance for the entire fuel system. Located in the upper part of the tank and ensures the normalization of pressure, with a decrease in the volume of fuel. Of the most common, 2 types of sapunes can be distinguished: simple (cone.shaped) and selected (float). Both options are widely used, both in amateur and professional tools.

In addition to standard valves, some saw models are equipped with completely unique elements. For example, to replace the saapon with Makita EA3203S and STIHL MS 660, you will need to choose a fully identical detail.

When clogging the valve bandwidth, the air that is necessary to normalize the pressure against the background of the pumped fuel will cease to flow into the tank. Since the capacity is sealed, vacuum will begin to form in it. With each new “eaten” portion of fuel, carburetor will be increasingly difficult to pump. At this pace, the work lasts several tens of seconds until the membrane pump rises. If the instrument stalled due to the clogged cabin, then when the gas tank plug is unscrewed, air is sharply absorbed into it, normalizing pressure.

How to check the fuel filter on the chainsaw

Reducing the throughput of the main fuel supply channel causes extremely undesirable consequences expressed in reducing power or a complete stopping of the tool with increasing speed. It is these problems that can be a distinct signal of fuel filter pollution. The brighter such problems are more expressed, the more the channel is clogged.

It is not always possible to establish the need to replace during visual inspection. In appearance, the filter can be clean, but its inner part of a tamped with small particles and weighing. Determine the cause of the malfunction for sure, you can experimentally remove the filter and starting the tool without it. If the work is normalized, then the installation of a new element is required.

At enterprises where the chainsaws are operated regularly, 5 days a week, the filter is changed about once every 3 months. If in 1 day the tool burns ≈ 5 liters of fuel, then in 60 days 300. For household saws, this indicator can be divided into 2, since they are equipped with less reliable filters. As a result, in home / amateur use, replacement should be made every 150 liters or 1 time per year.
