It should be noted that the gasoline grass mower is very easy to operate. It’s enough to see how other users use this unit to start using it fully. The basic technical functions are intuitive and easy to follow in practice. Properly running the gasoline grass trimmer is also not difficult. Not only that, there is almost no difference between devices of household and professional categories.
The key difference is the type of motor. On machines for professionals, it is more powerful and produces more rpm. The two-stroke engine is more often used in domestic models. Four-stroke units are more reliable and produce more force, so they are suitable for special conditions, difficult and overgrown areas.
In addition, it is necessary to take into account whether there is a cutting attachment in the delivery set.

How to get started?
How the lawn mower performs during the first start up is very important. Mistakes can reduce the life of the machine. The fact is that after starting, the moving mechanisms of the working device will rub against each other. In addition, the skills of using the trimmer are formed. This is very important if you are working with these machines for the first time.
You start with the inspection of the gearbox and the quality of its lubrication. Then the fuel mixture is prepared according to the instructions.
Important: such a running-in is useful not only when mastering a new technique, but also when preparing the grass mower for work after winter storage. If there is no or very little lubrication on the gearbox, the gears will be subject to very high friction. Because of this, the gears begin to heat up and wear out.
Noticing the lack of lubrication or its absence, you need to add a portion of “Lithol”. The procedure is very simple: unscrew the screw located on the bend of the gear housing. Use a technical syringe to add 1-2 ml of lubricant through the vacant channel. In daily work with the trimmer 1 time in 8-10 hours will have to lubricate the boom gearbox.
But the running-in of the lawnmower is not limited to filling up with oil.
Two-stroke engines need a combustible mixture of two-stroke oil and gasoline. It is prepared in the proportion indicated in the tool manual or on the lubricant label. Cooking fuel in small quantities so you only have enough for one trip. The stock of fuel must be placed in the following container:
It is a good idea to use a syringe to collect the oil. This will make it possible to observe the dosage more accurately. Sometimes there is another issue. the manufacturer of the tool and the manufacturer of motor oils indicate different proportions of the combustible mixture, so it is difficult to determine which instructions to follow.
The way out is simple: you need to run in the gasoline grass trimmer with as little oil as possible. Anyway the grease does not burn out completely, and its surplus forms a coke that clogs the piston and cylinder.
After completing the tests and pouring the fuel mixture, you should do the following manipulations
- place the grass trimmer on a level surface;
- Move the lever to the “closed” position;
- pump fuel into carburetor;
- Start the ignition system;
- pull the starter cord smoothly, waiting for resistance;
- immediately after that make 3 or 4 strong jerks;
- As soon as the engine starts to run, open the choke.
Inspection of lawnmower gearbox and its lubrication
Checking the gearbox before starting a gasoline grass trimmer should be done on a regular basis. Lack of lubricant or a small amount of it increases friction of the gear reducer gearing, which operates at quite high speeds. The result is overheating of the gears as well. Gearbox of brushcutter fails. To prevent the occurrence of such a failure during operation and helps regular inspection.
If you find, before starting the gasoline grass trimmer, a lack of lubricant in the gearbox or its absence, “LITOL” is put into the housing. To do this, you must unscrew the screw on the bend of the gear housing and pour “LITOL” in an amount of 1-2 ml.
Working with a gasoline trimmer for a long time, every 8-10 hours add grease to the gearbox of the boom.
The first start grass trimmer
When everything is checked and the fuel mixture is poured into the tank, the first start of the grass trimmer before running it in. This requires the following manipulation:
- Position the brushcutter on a flat, horizontal surface;
- Move the air damper control lever to the closed position;
- Pump a few pumps of primer fuel into the carburetor;
- Turn the ignition switch on;
- Gently pull the starter cord until you feel resistance;
- Then use the cord to make three to four jerks until the lawnmower starts;
- After starting, open the choke.
In case the lawnmower doesn’t start or stalls the first time, open the choke flap on the carburetor slightly and try to start again.
Preparing the right fuel mixture
Before you start breaking in a new hedge trimmer motor, you must also prepare the correct fuel mixture. As is known for two-stroke engines, it is prepared from special two-stroke oil and gasoline taken in certain proportions. You can find the proportions in the instructions that came with the tool or on the oil label. From the instructions, you will also learn the recommended type of fuel, as well as the recommended type of engine oil.
If you’re going to start a new brush trimmer, many people have a problem making the fuel mixture. And the reason for this discrepancy lies in the tool manufacturer’s instructions and in the engine oil manufacturer’s instructions. The former recommends a 1:25 ratio. I recommend 1:50 to a friend. Who to trust? How to proceed?
According to experts, if manufacturers write a 1:25 or 1:30 ratio in the manual for a lawn mower, it is likely that it is either a cheap tool with poor cooling, or the manufacturer does not know what oil the consumer will add. But the thing to understand here is that excess oil is not the best way to affect the performance of a grass trimmer. The excess oil does not completely disappear while the engine is running. It cokes, clogs the cylinder and piston.
What to do in this situation when starting a new tool? Ideal. Buy exactly the oil that is recommended by the hedge trimmer manufacturer. As for running engines, when it is impossible to buy the recommended oil, it is better to buy a good two-stroke Husqvarna oil for the gasoline tool of the same name. It’s not cheap, but it lasts a long time. You need to intervene in this, as it is written in the instructions of the can.
Preparing for the first start of the lawnmower
Before you make the first start of the mower, it is necessary to carry out a series of sequential actions:
We recommend to perform them not only when buying a new grass trimmer, but also when preparing the old tool for the new season after storage.
Basic rules and tricks when working with a brushcutter
To get good mowing results and long service life it is important to correctly operate and care for your brushcutter. Even if it’s the first time you hold a brushcutter in your hands, you will soon learn correct mowing techniques. Simply pivot in a semi-circle from right to left, moving evenly forward.
Here are some basic techniques and methods which help you to mow even large areas fast and achieve better results.
The basic mowing technique is the most common.
Because the cutting attachment turns counterclockwise, the right-to-left mowing motion is more common in working practice.The advantage of this technique is that the grass cuttings always fall on top of the cut surface.
Large, flat surfaces. the right technique.
Large flat areas are best mowed square. The area is squared, then you always mow along the outsides into the middle.
Basic technique in case of tall grass.
If you cut very high grass or hard weeds, it is recommended to mow in both directions of movement: at first you cut the higher part of the mowed grass in one movement to the right, and in the opposite direction (to the left). the lower part. Even in this case the grass cuttings remain on the left side.
Along the slope. mow after mow.
You will make excellent progress by mowing in a straight line, particularly on a slope: cut a swath parallel to the slope and then return along the mowed line. Then mow the next higher swath. Here too the grass cuttings are always placed on top of the cut surface.
Skilfully avoid obstacles. mow playfully.
To mow close to a tree or shrub without damaging limbs or trunks, a string trimmer is ideal. If there are a lot of plants at a small distance from each other, mowing is suggested before mowing. To do this, use the blade guard on your brushcutter as a guide. Always guide it exactly along a tree or shrub, and move it around. The trunk remains protected, the area around the trunk will be mowed.
Running-in of the EVDIRAL two-stroke grass trimmer engine.RU
A new growing season is on its way. Great owner time to check the arsenal of small garden equipment. power tiller, chainsaw, lawn mower and trimmer for grass, if anyone has, and shredder (shredder.
A new gardening season is on the way. Great owner time to check the arsenal of small garden equipment. power tiller, chainsaw, lawn mower and grass trimmer, if anyone has one, and shredder (shredder of garden waste). They all run on gasoline mixed with engine oil, and at their core is a two-stroke engine. A properly mixed fuel for two-stroke engines is essential for the longevity and performance of these machines.
The peculiarity in the work of the two-stroke engine is that the oil for the lubrication of its friction parts must be added to the gasoline, not in the lubrication system, as, for example, in a four-stroke car engine.
When preparing the fuel mixture for a two-stroke engine, it is important to observe the correct proportion of gasoline and engine oil, otherwise the tool can quickly fall into disrepair. Nevertheless, this simple rule is often violated. There are experimenters who don’t care about anything. they try to make a motocultivator work on pure gasoline.
Almost all types of air-cooled two-stroke engines for small garden equipment run on gasoline with an octane rating of 92. Spending money on the 95-rd gasoline is not required, but also to use its octane number below the 92nd is unacceptable. Well, and oil for the fuel mixture must be special. It can be purchased in the same place where the cultivators are sold. chainsaws, grass trimmers and shredders
The necessary proportions of engine oil and gasoline for preparing the fuel mixture, is usually indicated on the label. It is 1. 40 or 1. 50. Let’s change the proportions in grams to make it clearer: 25 and 20 grams of engine oil in 1 liter of petrol, respectively. For accurate dosage it is convenient to use a regular medical syringe.
Don’t be surprised by the price of engine oil for air-cooled two-stroke engines. Its price is considerably more expensive than car oil. But it is also very economical to use.
How to prepare a fuel mixture for the two-stroke engine
To do so, pour petrol first into a dry gasoline-resistant canister, and only after that. oil. If the opposite is done, the oil can flow and stick to the bottom and no quality fuel mixture will be obtained. Thus, it is unacceptable to mix oil with petrol in the tank. Only a ready-to-use fuel mixture should be used.
The easiest way to prepare the fuel mixture is to use 1 liter of gasoline. It’s a good idea to do it right before you start. But the volume of the tank, for example, a gasoline trimmer or Druzhba chainsaw, can be less than a liter. So, the leftover must be stored somewhere until the next time. An opaque gasoline-resistant canister is a good solution. It is undesirable to store the fuel mixture for two-stroke engines for over three months. Its chemical composition, in this case, will change and the unit of small garden equipment on such fuel, though it will work, but will make the countryside sound with its sneezing and roaring.
How to prepare a mixture for two stroke engines
Friends, the summer is on the threshold, that is, the season begins, and it is always some kind of work on your site at the cottage or in the cottage using gardening and other motorized equipment and therefore I am often asked how to prepare a mixture for two-stroke engines and what gasoline and oil to choose for them.
Most of garden machinery such as trimmers for grass, chain saws, brush cutters, some lawn mowers and tillers (some of them are models with 4-stroke engine) is equipped with two-stroke combustion engines, that is, as the name suggests, the work process in them occurs in two cycles, not four, such as in most gasoline car engines. For us it’s important now, that two strokes engines usually have the same lubrication system, that is the fuel tank is filled with petrol and oil mixture. So let’s break down the question of how to prepare a fuel mixture for two-stroke engines, what oil and gasoline to choose.
that’s how a two-stroke engine works
How to prepare a mixture for two-stroke engines of various motorized machinery
In any case you should read the manual of your device, whether it’s a grass trimmer, chain saw or something else. The thing is that different manufacturers give different recommendations on the oil to gasoline ratio. It may be 1:40 and 1:50 and 1:80. There are cases when there is a recommended ratio on the oil can itself In general, I personally use a 1:50 ratio. In general, do not particularly worry if the manufacturer recommends using a ratio of 1:50, and you have prepared a mixture of 1:40 or 1:60. Nothing happens at once, even if you produce a whole tank. It’s just that the former might increase the smokiness of the exhaust. I’ve seen people cook the mixture by eye and use regular olive oil in the absence of special oil! And nothing terrible happened. Personally I prepare mixture for all my units with two stroke engine in the following way: I take a 2 liters bottle of Pepsi, for example, and for oil sizing I use a regular 40 grams vodka shot glass. That’s how you get the 1:50 ratio. The technology itself is as follows. pour oil into the bottle through the funnel and then fill the bottle halfway with gasoline. Halfway to make it easier to stir. After that, shaking and spinning the bottle, mix it until it has a homogeneous color. Depending on the oil, it can be reddish, yellowish, or even bluish. After you have stirred, pour in the remaining half of the gasoline and shake once more. Everything. the mixture is ready for use.
