What A Petrol Trimmer Consists Of

Petrol trimmer won’t start? Elitech T750 Reasons and Solutions

In general, such a conversation should start with the fact that after buying a garden gasoline tool, it would be better to first familiarize yourself with the instructions attached to it. Then many problems could be avoided. But since this happened, the gasoline trimmer does not start, then you need to look for sources of inoperability. And in this article we will consider the main reasons why the trimmer does not start on the example of the Elitech T750 model, as well as we will tell you general recommendations for using such a tool.

You should start with the banal! Let’s figure out how to properly start a gasoline trimmer. It may be that the reason lies precisely here.

First you need to bring the red toggle switch on the trim bar to the “I” position. This means turning on the power. Then you need to switch the fuel supply lever on the carburetor and use the fuel “suction” button (similar to a pipette, located on the carburetor). This is necessary to supply gasoline to the engine. Return the fuel delivery lever to its original position. Finally, pull the starter handle sharply towards you. The trimmer should work. Try it several times if it doesn’t work the first time. If after such manipulations the situation has not changed and the gasoline trimmer does not start, then you should first inspect it yourself before you take it to the service center. There are two main reasons your garden trimmer won’t start:

  • Power circuit breakdown.
  • No fuel.
  • Let’s start with the ignition problems. In most cases, it is caused by the need to change the spark plug in the engine. This is done like this:
  • First of all, we must take care of the safety measures, making sure that the trimmer is disabled. We bring the above toggle switch to the “STOP” position.
  • Then remove the rubber cover from the spark plug and the wiring terminal. Using a special spark plug wrench, we unscrew the spark plug and replace it.
  • After that, we assemble the device and carry out the above procedure for starting the trimmer.

The second reason garden tools don’t work is because they run out of fuel. On the Elinech T750, the fuel tank is located near the engine, but on most trimmers it is there. We unscrew the cap from the tank and fill it with gasoline (the most optimal version of AI-92, it is inexpensive and does not clog the carburetor like the AI-76). Do not forget to add special oil for engines to the tank, 50 grams is enough for the gas tank, without it the engine will start to “sneeze” and will quickly become unusable. Then we close the tank with a cap, wipe the trimmer surface and our hands with a dry cloth. We also do the above manipulations to turn on the garden tool.

If the petrol trimmer still won’t start, then it makes sense to have it repaired. And the reason for this decision is simple. if you do not have the appropriate skills, equipment repair is almost impossible.

In order for the tool to serve as long as possible and not to have such problems, you should first of all read the instruction manual for the trimmer. Also, pay special attention to the engine running time at the trimmer. take a short break every 15 minutes of work and, finally, properly care for the tool, wipe it after work, lubricate with graphite grease. Observing such simple rules, you can significantly increase the service life of the tool and it is quite possible that you do not have to look for reasons why the gasoline trimmer does not start.

Gasoline trimmer cutting elements are usually supplied with the unit or purchased separately, depending on the type and complexity of the work that will be performed with its help. In most models, a special spool (bobbin) is included as standard, into which a cord (line) is wound, which serves as a cutting tool.

The bobbin design allows adjusting the cord length almost in a semi-automatic mode: just hit the stopper lightly on the ground, and the blockage from the inner spool is removed. Further, due to centrifugal force, during the rotation of the bobbin, the cord comes out, and since there is a special knife on the protective casing, the excess edges of the fishing line are cut off.

To mow thicker stems of plants (reeds, sedges, shrubs), you will need to use metal knives and cutters. They usually differ in the shape and number of cutting surfaces (petals). There are cutters that resemble circular saws in appearance, which are successfully used on powerful units. The disc trimmer is usually used when cutting young growth of trees.

Also, to expand the functionality of the lawn mowers, you can purchase (if not included in the complete set) special attachments shown in the following figure.

You should know that such attachments can only be installed on a trimmer with a collapsible bar. In this case, the device can turn into:

  • Brush cutter,
  • Chainsaw (you can cut branches in trees),
  • Brush (you can clean the tracks from snow and dirt),
  • Cultivator for tillage (surface).

Electric trimmer

This type of mower is popularly referred to as “electrokosa”. It also fits over the shoulder with a belt and is very easy to operate.

Principle of operation

The operation of the trimmer with a gasoline engine is as follows:

  • With the help of the starter, the operation of the internal combustion engine is started (how the engine works is a separate topic);
  • Rotation from the engine crankshaft is transmitted to the gearbox by means of a clutch mechanism and by means of a shaft located in the rod;
  • The rotation of the gearbox is transmitted to the spindle, on which the cutting elements are fixed;
  • Cutting elements, due to the high speed of the spindle, cut grass and bushes;
  • Spindle speed depends on the force of pressing the gas button.

Petrol trimmer

This type of trimmer has an indisputable advantage over the electric one, since it is not “tied” to an electrical outlet and can be used in places far from the electrical mains.


The method of securing the mower to your body during operation should be taken seriously. This is due to the fact that the weight of the unit with a gasoline engine cannot be called small. And if a large amount of work is performed with this apparatus, then its weight causes fatigue in the back and muscles of the shoulder girdle of the user. Belts are of the knapsack type and shoulder straps. Most home trimmers use padded, wide shoulder straps.

How a grass trimmer works

In order to improve parks, squares, lawns near a house or a summer cottage, it is customary to use different types of equipment that effectively cut grass and small shrubs. The traditional lawn mowers, the device of which did not allow mowing grass close to trees, in hard-to-reach places, on difficult terrain, etc., were replaced by more advanced and multifunctional units. trimmers. There may be differences in the trimmer design: engine location (top or bottom), as well as the type of drive: gasoline and electric.

Unit device

There are a huge number of models of petrol trimmers on the market. But, despite this diversity, they are made according to the same principle. At the very top of the trim tab there is a gasoline engine (1), a fuel tank (2) and a starter (3) for manually starting the drive. The motor is connected to the working tool by means of a rod (4), inside of which there can be either a flexible shaft or a rigid one. The bar often consists of several parts (sections) and can be either collapsible or one-piece.

The handle (5) can have different shapes. It contains controls (6). The control module (6) is connected to the drive by means of a cable (7). A gearbox (8) is installed at the bottom of the device, the task of which is to transfer the rotation of the shaft to a spindle with a cutting tool (9), consisting of a reel with a fishing line (cord) or from a special knife. For the safety of the user, a guard (10) is installed above the cutting tool.

This switch makes it easier to start the unit. It can be used to quickly warm up the engine when the ambient temperature is low.

In turn, the handle with control elements has the following device. In the most visible place of the handle is the button (1), which interrupts the ignition circuit. It is used to stop the engine if the need arises. The throttle trigger (2) is used to control the carburetor throttle, which is responsible for the amount of fuel supplied to the engine. The button (3) located below the Stop button protects against accidental pressing on the gas. Until the safety button is pressed, the gas trigger will be locked. In order not to constantly hold the throttle trigger with your finger, if a long trimmer operation is required, a stopper button is used, which fixes the control key in the pressed state.

Device device

An electric mower differs from lawn mowers in the type of drive used in it, namely, an electric motor installed on it. Below is a diagram on which all the main units of the unit are clearly visible.

Electric trimmers, can be produced with different engine positions.

  • The motor is located at the top of the unit. This arrangement of the drive is used in devices whose power can reach 1.4 kW. Thanks to this, tall grass, including wet grass, as well as small shrubs with thin stems, are easy to cut. Usually, an electric scythe includes a fishing line and a metal knife.
  • Motor at the bottom of the unit. With this arrangement of the motor, the mechanical part of the apparatus is significantly relieved, since the use of a gearbox and a shaft that transmits rotation from the motor is not required. The cutting unit is mounted directly on the spindle of the electric motor, which increases the reliability of this design.

But still, such a structure of the unit with the absence of a gearbox affects the speed of the cutting tool. Due to insufficiently high speed, such a unit can only mow young and not very dense grass.

There are also cordless trimmer models. But these devices are not able to work for a long time, and besides, they are low-power (used only for grass, not very thick and young). Since the battery needs periodic recharging, a spare battery is required to use the unit more efficiently.

Because of their quietness and mobility, cordless trimmers are often used in places where noisy machines cannot be used, such as hospitals, holiday homes and hotels. They are also very convenient to use for cutting grass in hard-to-reach places and when working on terrain with various obstacles. elements of landscape design, where an electric cable would interfere with movement.

Principle of operation

The principle of operation of the electric trimmer is distinguished by its simplicity:

  • The power cable is connected to a 220V outlet using an electrical plug (it is very important that the outlet is grounded);
  • The “ON” or “Start” button is pressed on the engine body;
  • After starting the engine, the rotary motion from its rotor is transmitted to the gearbox by means of a flexible or rigid shaft built into the rod (except for units with a lower engine location);
  • The device is ready for operation after the spindle reaches its maximum speed.

Electric trimmers have some operating restrictions associated with the use of electric motors in them: do not work in wet weather, mow grass wet from dew or rain. This rule especially applies to units with a lower engine mounting.

How to put on a belt

If the tool has a shoulder attachment, hang it on the shoulder before starting work. The trimmer is fixed to both shoulders if it has a knapsack mount.

The bicycle handle model is held with 2 hands, the D-shaped handle is wrapped around the palm. The belt must be worn so that it is comfortable, then the back will not get tired.

Mowing tall grass

If you need to cut tall grass, this is done in several passes. The lawn is processed 2-3 times. The rotating part is lowered from top to bottom, in this case the grass does not wrap around the reel.

The operator should be aware that grass wrapped around the reel will overheat the motor. If this happens, the mower is turned off and the coil is cleaned.

It is most effective to cut the grass with the ends of the line rather than the entire length. In the second case, the tool works worse, the motor may be overloaded. If you need to cut grass over a large area, tilt the trimmer towards the mowing side to increase efficiency.

First start

Before the first start-up, the operator assembles the mower, the procedure is described in the instructions that come with the product.

If the trimmer is gasoline, it must be checked before use. The fuel tank is filled up to the neck.

The engine must run in to fuel, so when first started it must run for a few minutes without load. Then start mowing the grass.

We mow under hay

It is better to mow hay not with a fishing line, but with a metal disc. The grass is cut at the root, keeping its length as much as possible.

Running in

Before starting operation, be sure to run in gasoline mowers. The operator turns on the engine, it should run for some time at idle speed. It is necessary to ensure that the engine does not overheat, there should be no load.

When running in lawn mowers, the load is gradually increased. If you start working at high speeds, the motor will not work well, this will affect the further operation of the mower.

When you start it for the first time, you should not completely exhaust the temporary resource. After the engine runs at idle speed, you can proceed to treating the lawn. the lawn mower should run no more than 15 minutes, after which the motor is turned off, it should cool down.

If you need to run the trimmer, the braid is first assembled. Then do test runs at least 3-5 times. If the engine is running well, proceed to mowing. At first they work no more than 5 minutes, then the duration of work is gradually increased.

Principle of operation

If we consider the principle of the trimmer, then it is similar to a hand scythe. The difference is that it is equipped with a motor, with its help the cutting element is rotated.

Manufacturing companies produce the following mower models:

  • On which a gasoline engine is installed. These garden tools have a fuel tank, this is their distinctive feature.
  • Devices with an electric motor. These tools are lighter because they don’t have a fuel tank. But when choosing such models, you need to take into account that a power source is needed for their operation.

All electric streamers can be divided into those that run on batteries and models that are connected to the mains. Each type has its own characteristics, but they affect the power supply unit. If you do not take it into account, then the rest of the design is similar in different devices.

If you take any trimmer model, then it consists of elements such as:

  • Motor;
  • Fuel tank (electric lawn mowers do not have one);
  • Levers with which the mower is controlled;
  • Grass cutting knife;
  • Barbell;
  • A spool with a wound line, which is used for cutting grass;
  • Protective cover;
  • Bevel gear.

The motor is placed near the mowing head and can be mounted from below or from above. The gearbox is only available for models with a straight bar. If it is bent, then the main bearing becomes the connecting element. It consists of 2 bushings.

The choice of the cutting element depends on how hard the grass must be mowed. Most often, a fishing line is used in the work, it is called a cord. There are products of various shapes on sale, among buyers in demand are spiral and round.

The fishing line is wound on a spool, it is inserted into the spool, while the 2 ends of the wire remain free. When the mower engine starts to run, the bobbin rotates, the grass is cut with the free ends of the line.

How the trimmer works and how to use it correctly: refueling and first start

lawn mowers are devices that make it easy to maintain lawns. The question of how to use the trimmer is asked by those buyers who are just going to purchase a garden tool. The industry produces devices of different types, so when choosing, you need to pay attention to their characteristics.

Wet weather operation

Electric mowers must not be used in the rain, there may be a short circuit. When the precipitation stops, you need to wait for the grass to dry.

Not all gasoline mowers are protected from moisture, so some manufacturers prohibit the operation of mowers in the rain.

How to refuel the benzotrimmer

petrol-powered lawn mowers are available with two-stroke and four-stroke engines. The first option is much more common. What are the differences between them:

  • Trimmers with a 2-stroke motor have a faster response to pressing the engaging lever (for this reason, lawn mowers are mainly equipped with this type of engine);
  • A tool with a two-stroke engine will be much lighter and also easier to maintain;
  • The fuel consumption of a two-stroke engine is about 30% higher than that of a 4-stroke engine with the same power;
  • 4-stroke engine is more environmentally friendly, since the fuel in it burns completely and is not emitted into the atmosphere, and its noise level is much lower;
  • And the most important distinguishing feature is the refueling: the 2-stroke engine is equipped with one common tank, into which gasoline mixed with oil is poured; 4-stroke has a separate gas tank and a tank for engine oil.

For refueling, you must use fresh AI-92 or AI-95 gasoline and high-quality motor oil for gardening equipment (manufacturers produce different oils for 2- and 4-stroke engines). The oil can be mineral, semi-synthetic or synthetic.

The proportion of gasoline and oil for trimmers with 2-stroke engine can be found in the instruction manual for the particular model. Usually it is 50: 1, in some cases a ratio of 25: 1 or 40: 1 is recommended. It is necessary to prepare the fuel mixture in a separate container with exact proportions. Never pour liquids “by eye” directly into the tank without first mixing them. Detailed instructions for mixing gasoline oil, with and a description, can be found on our website here.

If even in this case the trimmer does not start, it is worth assessing the quality of the contact between the high-voltage wire and the candle. In the absence of a spark (if there is a reliable connection between these elements), most likely, the problem is caused by a breakdown of the ignition unit. In this situation, you will have to turn to the services of wizards who will reinstall the node.

We identify the cause of the malfunction

To repair your lawn mower yourself, it is best to follow the simple to complex principle. First, check if there is enough gasoline in the tank. If the mower stops starting after wintering, it is worth draining the old fuel and replacing it with a new one. Sometimes low-quality gasoline comes across, which can sediment or even stratify over the winter, and some lawn mower motors are very sensitive to fuel quality.

If you are confident in the quality of the gasoline, but the mower is showing no signs of life, the next thing to do is check the spark. To do this, you need to remove the wire with a cap from the candle and unscrew it with a special candle wrench, which should be included with the lawn mower. Then put the cap over the spark plug, attach the threaded part to the metal part of the engine and ask someone to jerk the starter. At this moment, a bright blue spark should appear, which is clearly visible even during the day. Keep in mind that you need to lean the spark plug against a clean metal surface of the engine that is not covered with paint and that can conduct current.

The reasons why the gasoline trimmer starts and stalls

The tool, despite its small dimensions, is a complex technical device. If you study the operating instructions, it turns out that the reasons why the lawn mower does not start are known and removable. It is necessary to consistently eliminate the factors that make it difficult to start the tool. Usually start with more accessible nodes with an easy health check.

Troubleshooting strategy

Where to start troubleshooting if the trimmer won’t start? In situations where the tool stalls immediately after starting, it is worth inspecting the following components of the unit:

  • Fuel tank;
  • Spark plug;
  • Fuel and air filter;
  • Exhaust channel;
  • Breather.

It is the breakdown of the above locations that most often leads to the fact that the trimmer does not start well. Let’s look at how to eliminate such troubles.

READ  Electric Grass Trimmer Which Is Better To Choose

What to do if the used fuel mixture is in good order, but the petrol trimmer still won’t start? The reasons for the failure of the mechanism may lie in the excessive moisture of the candle channel. To diagnose and fix the problem, you must do the following:

  • Unscrew the candle. Wipe it thoroughly and then dry it.
  • Drain excess fuel in the chamber through the appropriate plug hole.
  • Clean the old plug if there is carbon deposits on its surface. To cope with the task will allow the use of a regular ladies’ nail file or a file.
  • When installing the element in place, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the gap.
  • Assemble the functional block back.
  • Try to start the trimmer.

It is recommended to dry the candle channel for at least half an hour. However, in no case should you resort to calcining its elements. After all, heating the spark plug can lead to its final damage. What to do if the function block was serviced in accordance with the above recommendations, but the trimmer does not start, there is still a spark? In this case, it is worth treating the threaded connection with gasoline. The latter does not need to be abundantly impregnated with fuel. It should only be slightly damp. Such actions should be taken to ensure ignition. After all, no matter how strong a spark the candle gives, in an absolutely dry chamber there simply will not be anything to ignite.

Lawn mowers diagnostics and elimination of causes.

DIY lawn mower repair

Many owners of gasoline lawn mowers sooner or later face technical problems with this technique. Most often, problems arise after three to four seasons of active use of the lawn mower or after the equipment spends the winter in an unheated garage. These problems manifest themselves as follows:

  • The lawn mower will not start
  • The lawnmower starts, but soon stalls
  • Lawn mower engine runs intermittently
  • Lawn mower engine is not running at full power

It doesn’t matter which engine is on your mower: an expensive Japanese Kawasaki or a simple Chinese Lifan, over the years of operation, these problems are more likely to appear in all lawn mowers. However, do not get upset and rush to take your mower to a service center. In the vast majority of cases, a lawn mower can be repaired by hand without much difficulty. In this article we will show you step by step how to do it.!

Petrol Trimmer Starts And Stalls

Why won’t the petrol trimmer start? Causes and their elimination

Recently, the gasoline trimmer has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized scythe allows you to quickly put your personal plot in order. However, it sometimes happens that the trimmer does not start hot or even cold. In such situations, you have to independently determine the cause of the malfunction. Let’s figure out what to do if the trimmer won’t start. The reasons that most often lead to such troubles will be discussed below.

Taking proper care of your chainsaw

There are no unnecessary phrases in the operating instructions, everything that is offered is aimed at trouble-free operation of the lawn mowers. Cleaning all parts after each work cycle facilitates the easy removal of uncured residues and dirt. Only the cooled nodes need to be cleaned. This technique contributes to the quality of air cooling of the engine and gearbox.

For refueling, you must use fuel with the oil recommended in the instructions. If the combustible mixture is left in the fuel tank, the oil will float up and, when started, will land on the damper, impairing its adjustment. The mixture can sediment and clog the fuel feed in the carburetor.

When storing the equipment for the winter, conduct an audit, lubricate the gearbox and piston system, Wrap the entire saw in oiled rags and store in a dry place.

It is impossible, it is dangerous for the tool and the health of the mower, to use a metal cable instead of a fishing line. It cuts more efficiently, but the load on the gearbox and engine increases. A worn-out piece of wire flies at the speed of a bullet when it comes off. Effective mowing can lead to early wear of the engine piston group. For more efficient mowing, it is suggested to use the “star” line profile.

READ  Petrol Echo Trimmer Will Not Start

Semi / professional petrol trimmers used to maintain large summer cottages and gardens. Differ from other types in combination of medium power and mobility.

Household structures are small in size and have a less powerful engine. The hose in many models is removable, which makes it easier to transport by road. It is advisable to use in areas not exceeding 20 acres.

Operating rules

The fuel is a mixture of gasoline and two-stroke oil (ratio 1:50);

Before mowing, stones, glass and other debris should be removed from the site;

It is prohibited to turn on the mower without a protective shield;

To prevent overheating of the engine during operation, you need to take breaks;

It is necessary to operate the tool using special equipment (glasses, trousers made of hard fabric).

See an overview and how the trimmers work. Petrol trimmer device

The petrol trimmer consists of the following elements:


It is recommended to wash and dry the tool after each mowing. The foam filter should be moistened with oil from time to time. If used frequently, check the fuel filter once a week. Regularly check the tightening of screws and nuts. Cutting elements in the form of knives must be sharpened, and the line is used only of the corresponding diameter.

Timely and high-quality care will extend the operating period of the tool.

How to extend the life of your trimmer?

After each mowing, wash the tool, clean the head from dirt and dust. The lawnmower should be filled with high quality fuel (at least 92 brands). When choosing an oil, give preference to the types used for high-speed technology.

How to use your lawn mower properly

The trimmer is filled with fuel before mowing, after which all elements are checked. If the line is “eaten through”, it is worth winding 2-2.5 meters of a new cutter around the head. The length of the winding depends on the volume of the drum and the thickness of the line.

Before starting the lawn mowers, walk around the area to remove stones, metal and glass. During operation, they fly off and can injure the skin. The presence of a casing on the hose is also checked.

It is worth cutting with the trimmer intermittently to prevent the engine from overheating. For safety reasons, you must wear protective clothing and glasses during work.

What A Petrol Trimmer Consists Of

Petrol trimmer: device, types, principle of operation

Various methods are used to control weeds, but one of the most effective is mowing the grass with a mower. Motorized devices are divided into gasoline and electric. Through comparative analysis, the benefits outweigh the petrol trimmers. This technique will be discussed in the article.

What types of trimmers can be repaired?

Household models most often develop their modest resource, after which they are written off. In some cases, it is possible to replace the head cover, which is subject to abrasion from constant rubbing with stones and debris.

Semi-professional and professional models can be repaired to extend the service life of the technician. However, when buying, you need to take into account that the repair of powerful equipment always costs an order of magnitude more.

The device and types of petrol trimmer

The trimmer is designed for cutting weeds, depending on the type, it can be used in the private sector and utilities.

The lawn mower construction consists of the following elements:

Engine (two- or four-stroke gasoline);

One-piece or collapsible hose (straight or curved shape);

Control sticks (bicycle handlebars or D-shaped);

The head on which the fishing line is held;

Gasoline trimmers are of three types, the difference between which lies in the type of engine, power and type of cutting part.

Household lawn mowers, as a rule, have a compact size, low-power engine. Many models are equipped with a collapsible hose, which makes it easier to transport the tool in vehicles. The trimmer does its job well in areas up to 20 acres.

Semi-professional equipment is used for the beautification of large households with a vegetable garden and a garden. Ideal for lawn mowers, due to the combination of compactness and good power, sufficient for processing large areas.
