Types of trimmers on a gasoline engine

Let’s take a look at the different types of petrol trimmers and find out which jobs each one is best for.

Gasoline trimmer: the purpose of the tool in the country

A lawn trimmer is essentially a gas-powered grass scythe. It is used for mowing ornamental grass (leveling, cutting), for mowing weeds, for mowing grass for hay.

The trimmer does this quickly and neatly, in addition, it is light and easy to maintain and does not require a lot of storage space. The main difference between a trimmer and a lawn mower.

The trimmer can not only cut grass and herbaceous plants, it perfectly cuts off not thick (2.5-3 cm in diameter) branches of trees and shrubs. So it will replace the pruning shears in the garden.

Trimmer knife and line

The line included with the trimmer is used only for cutting grass. Several types of fishing line are distinguished by the type of pattern:

  • In the shape of an asterisk. For green decorative lawns or young grass;
  • In the shape of a square. For tall grass with thick stems;
  • In the shape of a circle. A versatile look, suitable for both lawn and woody and dry grass stems and leaves.

For cutting branches, cutting shrubs, you will need a knife. There are models equipped with a line only, and there are models with both a line and knives.

The reason why the trimmer fails may be:

  • Tank overflow;
  • Excessive pumping of fuel into engines equipped with a manual supercharger;
  • Wear in the motor of valves, cylinders, injectors, cam followers and other moving parts;
  • The tanks are out of gasoline and / or oil;
  • The spark plug is out of order;
  • Clogged fuel or air filters;
  • The valves in the motor are out of alignment or burnt.

How to start a petrol trimmer?

  1. Prerequisites
  2. How do I start the trimmer or lawn mowers?
  3. Starting the lawn mower for the first time or after a long period of inactivity
  4. Adding fuel through the spark plug holes
  5. Checking the ignition system
  6. Cleaning the engine
  7. Checking the integrity of the spark arrester
  8. Unstable carburetor operation
  9. Draining fuel from the gas tank

How to start the trimmer correctly is a question that owners are puzzled with in the event of a device breakdown. And after a successful trimmer repair, the owner tries to avoid repeating the same situation.

How do I start the trimmer or lawn mowers?

The new trimmer is simple during commissioning.

  1. Check the motor type of the device. Trimmers are equipped with a 2- or 4-stroke motor.
  2. Buy oil for this type of motor. Gasoline for the trimmer. Ai-92/93/98, sold at all gas stations.
  3. Mix oil with gasoline. Mineral oil is mixed in a ratio of 1: 34 with gasoline, synthetics. In 1: 50. Follow the trimmer manufacturer’s recommendations for oil viscosity (see the label on the flask). All-season oil 5W-30 is used more often. Do not use untested car oils.
  4. Pour a small amount (for example, 0.5 liters) of the resulting fuel into the tank.
  5. Close the air damper by sliding the desired lever (see instructions).
  6. Turn the ignition key (or handle) to the “on” position. Otherwise the trimmer will not start. Beginners often make this mistake.
  7. Pump some fuel into the carburetor. If there is a manual “rocker” with a separate button or lever (see instructions). It takes 4-7 clicks.
  8. Place the trimmer on a level surface.
  9. Pull on the starter cord gently until you feel it slow down. Then pull it out sharply, but not completely. Repeat this movement up to 4 more times.
  10. If the engine does not start, open the air damper again, otherwise the candles will flood with gasoline with further movements of the cord. Perform 2-3 attempts to start the engine with the handbrake open.
  11. If the engine still does not start, close the throttle and make several more attempts to start it.
  12. After starting the engine, press the throttle lever to idle.

How to get started?

The literacy of the first start-up largely depends on how the gasoline scythe will show itself during further operation. Errors can reduce the life of the device. The fact is that after starting, the moving mechanisms of the working apparatus will rub against each other. Additionally, the skills of using the trimmer are formed. This is very important in cases when this technique is used for the first time.

Begin by inspecting the gearbox and the quality of its coating with grease. Then the fuel mixture is prepared according to the instructions.

If you notice a lack of lubrication or its absence, you need to add a portion of “Litola”. The procedure is very simple: unscrew the screw located on the bend of the gear housing. Through the freed channel, add 1-2 ml of lubricant with a technical syringe. During daily work with the trimmer, you will have to lubricate the boom gearbox once every 8-10 hours.

But running in lawn mowers is not limited to oil filling.

Two-stroke engines require a combustible mixture of two-stroke oil and gasoline. It is prepared in the proportion indicated in the manual for the instrument or on the lubricant label. Fuel preparation should be done little by little, so that only one mow is enough. You need to place the fuel supply in the following container:

  • Plastic canisters;
  • Glassware;
  • Metal containers.

It is recommended to take oil with a medical syringe. This will allow you to more accurately observe the dosage. Sometimes another question arises. The manufacturer of the tool and the manufacturer of engine oils indicate different proportions of the combustible mixture, so it is difficult to decide which instructions to follow.

After completing the tests and filling the fuel mixture, the following manipulations should be done:

  • Put the trimmer on a flat surface;
  • Move the lever to the “closed” position;
  • Pump fuel into the carburetor;
  • Start the ignition system;
  • Pull the launching cord with smooth movements, expecting resistance;
  • Immediately after that, make 3 or 4 strong jerks;
  • As soon as the motor starts running, open the choke.

Features of running-in lawn mowers

Lawn mowers, they are also trimmers, are popular. These low-cost machines can be used in summer cottages, in personal agricultural holdings, farms and public utilities. However, the practicality of such devices can be appreciated only by those who can properly start using them.

Features

It should be noted that the petrol braid is very easy to operate. It is enough to see how other users use this unit to start using it fully. Performing basic technical functions is intuitive and does not require any difficulties in practice. Correctly running in a gasoline trimmer is also not difficult. Over, there is almost no difference between household and professional devices.

The key difference is the type of motor. On professional equipment, it is more powerful and produces more revs. The two-stroke engine is more commonly used in household models. Four-stroke units are more reliable and produce more force, therefore they are suitable for special conditions, difficult and overgrown areas.

Preparing the correct fuel mixture

Before starting the running-in of the new engine of the lawn mowers, it is also necessary to properly prepare the fuel mixture. As is known for two-stroke engines, it is prepared from special two-stroke oil and gasoline, taken in certain ratios. You can find out the proportions from the instructions that came with the tool or on the lubricant label. From the instructions, you will also learn the recommended type of fuel, as well as the recommended type of engine oil.

When going to run in a new lawn mower, many are faced with a problem in preparing the fuel mixture. And the reason for this is the disagreement in the instructions of the tool manufacturer and in the instructions of the engine oil manufacturer. The former recommend a 1:25 ratio. The latter recommend 1:50. Whom to believe? How to proceed?

According to experts, if manufacturers write a ratio of 1:25 or 1:30 in the instructions for a lawn mower, then most likely this is either a cheap tool with poor cooling, or the manufacturer does not know what kind of oil the consumer will add. But here you need to understand that an excess of lubricant does not in the best way affect the performance of the trimmer. Excess oil does not completely burn out when the engine is running. It cokes, clogs the cylinder and piston.

How to deal with this situation when running in a new tool? The ideal option would be to purchase exactly the oil recommended by the lawn mower manufacturer. In the case of run-in engines, when it is not possible to purchase the recommended oil, it is best to purchase a good Husqvarna two-stroke oil for the gasoline-powered tool of the same name. It is not cheap, but it lasts for a long time. It is necessary to stir it as written in the instructions on the bank.

Preparing for the first start of the lawn mower

Before you start the lawn mowers for the first time, you must perform a number of sequential actions:

  • Inspect the gearbox and lubricate it;
  • Prepare the correct fuel mixture.

Starting the trimmer for the first time

When everything has been checked and the prepared fuel mixture is poured into the tank, the moment comes for the first start of the trimmer before running it in. To do this, you need to perform the following manipulations:

  1. Place the mower on a level, horizontal surface;
  2. Move the choke control lever to the closed position;
  3. We pump fuel into the carburetor with several strokes of the primer;
  4. Turn on the ignition switch;
  5. Smoothly pull out the starting cord until you feel resistance;
  6. Then make 3. 4 sharp jerks with the cord until the lawn mower starts;
  7. After starting, open the air damper.
