how to start a lawn mower

To spend less time and effort mowing grass in the area, you need to use the mechanisms designed for this lawn mowers, trimmers and lawn mowers. With their help, it will be possible to maintain the area adjacent to the house in excellent condition. The advantage of lawn mowers is that it is not tied to a power source like electric scythes. In addition, its application allows mowing grass on uneven terrain, as well as in hard-to-reach places (for example, under a bush). It is also less safe, since when using electricity there is always a possibility of electric shock.

What to look for when choosing a lawn mower?

Since the purpose of the scythe is precisely to mow vegetation, the first thing to do is to look at the cutting tool. Domestic lawn mowers are equipped with steel or plastic blades. A saw blade or nylon scaffolding is also used as a cutting part. Based on this, it must be taken into account that the fishing line is absolutely unsuitable for work in areas where there are thickets of bushes. She also will not be able to cut small branches and young shoots from trees. Plastic knives, in turn, cannot be sharpened.

It is better to purchase more versatile models that have the ability to change the cutting tool. In this case, you need to ask how easily and quickly such a replacement is made. You need to understand that steel knives and discs become dull during operation. What then? If they are sharpened, how? Can you do it yourself? If the manufacturer provides spare cutting tools, how much is included in the package and can be purchased at retail? After all, the lawn mower itself is designed for a long service life. A steel knife may break, but where to get another?

Chainsaws are usually equipped with a 2 or 4 stroke engine. The first ones are somewhat lighter, but their operation is much more noisy. Although the set may include headphones that are used during work. Therefore, everyone chooses a model at their discretion. The scythe power can be up to 1.5 hp. Another such nuance of the 4T model needs to be kept somewhat tilted, at an angle. This is necessary for oil to get on all parts of the braid. But the 2T models can be held as you like, in any position they work stably.

Practice shows that corner models are less reliable, and their power is less. However, with a bent bar, steel knives are not used, since with such a configuration, the knife is easy to break. There are models with a folding bar, but they are short-lived.

The handles can be of various shapes. They are called T, D or J shaped. The T-handle is well suited for work in open and relatively level areas. This configuration follows the shape of a traditional braid and allows for large, wide sweeps. The D-shaped handle is more suitable for working in difficult areas: along fences and buildings, under bushes, among trees. For areas with high vegetation, a scythe with a J-handle works well. By the way, it is the best in terms of safety.

And yet, focusing on the technical characteristics and cost of a particular model, do not forget about the convenience of using this particular braid. If it fits well in your hands, does not impede movement, then, most likely, your choice was made correctly. I recommend watching a specialist tells about the choice of lawn mowers and its maintenance:

Winter launch features

Before starting work in winter, it is recommended to first bring the chainsaw into a warm room for 10-15 minutes. If this is not possible, start the tool at idle speed by moving the choke to the middle position. Only increase engine power after preheating. Some models have the ability to switch air intake in summer and winter mode, this is the best solution if you often work in the forest at any time of the year.

Can I start without a starter?

It is impossible to start a chainsaw without a starter. In the absence of this element, disturbances will occur in the engine cooling process, since there is a so-called volute in it, which regulates the flow of cold air from the flywheel impeller to the engine cylinder.

How to start a chainsaw?

In most European models, the starting system and starter have a similar device, mechanism of operation. An exception is the old domestic chainsaws (Ural, Lesnik). On the body there is a handle through which a cable is passed. If you lift it, the cable engages with the drum of the ratchet mechanism, several revolutions of the crankshaft occur. At the same time, the fuel is ejected and ignited with the help of a candle, after which the chainsaw starts up. To simplify the start, the following mechanisms can be implemented in high-quality chainsaw models:

  • Installation of a damper in the carburetor for preliminary enrichment of the fuel mixture;
  • Decompression valve, which reduces the working pressure in the engine cylinder;
  • A spring that, during the movement of the cable, simplifies the unwinding of the crankshaft;
  • Additional pump for pumping fuel (usually found in American manufacturers).

The starter motor is constantly subjected to dynamic loading. Because of this, it can fail at any time right during launch. With frequent use of the saw, it is recommended to carry out preventive maintenance at least once a year. It is recommended to replace the cord in the starter only with two people, since it is required to securely fix the spring.

How to properly start the trimmer is a question that the 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.


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.

Starting the lawn mower for the first time or after a long period of inactivity

A lawn mower differs from a trimmer in that it is not a fishing line that acts as a grass cutter, but a mechanical reducer or a gear-based winch equipped with a knife. The knife drive is much more powerful than the forestry mechanism, a powerful lawn mower is also used when cutting bushes. Both Chinese and European lawn mowers are no different when the declared power is real.

Litol or grease is used to lubricate the gears of the reducer. After checking the gearbox, prepare the motor for operation according to the above instructions. If the start fails, the problem is already in the engine.

Starting a warm engine

It’s very simple. Move the switch to the working position and pull the cord before starting. If you do everything according to the instructions, then there should be no problems with starting a working lawn mower.

Fuel mixture and refueling

For the convenience of preparing the fuel mixture, it is better to have a special canister, where one part contains gasoline, and the other contains 2-stroke oil. We recommend getting one like this, it is very convenient to use

Next, take a measuring container with a scale applied to it, with its help you can prepare the mixture as accurately and quickly as possible. Look in the instructions what brand of gasoline and 2-stroke oil are recommended by the manufacturer of your lawn mowers. Pour gasoline and oil into a container for preparing a fuel mixture, according to the proportions indicated in the instructions. Then carefully pour the prepared mixture through a funnel into the trimmer fuel tank. The ratio of gasoline to oil should be exactly as indicated in the instructions. This is a very important point!

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.

First start-up and running-in of lawn mowers

Correct initial start-up and running-in of a lawn mower are very important steps in getting started with a new tool. On the one hand, they allow you to preserve the service life of a gasoline engine, laid down by the manufacturer, since at this stage, the grinding of moving units and parts takes place. On the other hand, the first necessary skills of working with a trimmer are acquired when it comes to the first tool in life.

  • Preparing for the first start of the lawn mower
  • Inspection of the lawn mowers gearbox and its lubrication
  • Preparing the correct fuel mixture
  • Starting the trimmer for the first time
  • Let’s start running lawn mowers

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.
