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 2-stroke oil. We recommend getting one like this, it is very convenient to use https://ru-sad.ru/prinadlezhnosti-dlya-sadovoy-tehniki/dlya-benzopil/kanistryi/
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 https://ru-sad.ru/prinadlezhnosti-dlya-sadovoy-tehniki/masla-i-smazki/ are recommended by the manufacturer of your lawn mowers. Pour gasoline and oil into the container for preparing the 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 and oil should be exactly as indicated in the instructions. This is a very important point.!
Starting a warm engine
Starting lawn mowers with cold engine
To start the lawn mower for the first time, locate the choke lever and set it to the “closed”. Turn on the ignition on the handle. If your model has a manual fuel pump, popularly called suction, then press it 3-5 times until you see the fuel mixture inside the primer. The tool is now ready to run. Lay the trimmer on a flat surface to ensure a stable position. Pull the starter rope gently until you feel its resistance, and then pull the rope towards you 3-5 times with a sharp movement.
If the engine starts after 5 jerks, open the choke. If this does not happen, open the air damper anyway (if the damper is open and you continue trying to start the engine, the fuel will flood the spark plug and have to dry it, and this is a waste of time).
If the engine does not start when the throttle is open, close it and continue pulling the cord. The first launch can be quite difficult and require up to 15 jerks. After the engine has started to work, press the throttle lever once, so you engage idle speed. Now let the engine run and warm up. After that it can be stopped by pressing the button. “Stop”.
How to start a petrol trimmer
The process of putting lawn mowers into operation, whether you bought it now or got it after winter storage, the rules listed below will allow you to avoid basic mistakes that can damage the tool.
Let’s say you just bought a petrol trimmer. Take the instructions out of the box and see if you have all the parts listed for the lawn mower. After that you can start building.
Basic startup errors
Let’s list the main mistakes that beginners make when starting a gasoline trimmer:
- starting the engine with the ignition off;
- starting with a closed damper with the number of jerks more than 5 times;
- improper fuel mixture.
Inspection of the lawn mower gearbox and its lubrication
Checking the gearbox before starting the gasoline trimmer must be created on a permanent basis. Lack of lubricant or a small amount of it increases the friction of the gear transmission of the reducer, which operates at a sufficiently high speed. As a result, overheating of the gears also occurs. The lawn mower gearbox is out of order. Prevent the occurrence of such a breakdown during use and helps constant inspection.
If, before starting the gasoline spit, the lack of lubricant in the gearbox or its absence is detected, “LITOL” is put into the body. To do this, unscrew the screw on the twist of the gear housing and sprinkle “LITOL” in the amount of 1-2 ml.
Working with the petrol trimmer for a long time, add grease to the boom gearbox every 8-10 hours.
Preparing lawn mowers
Start by inspecting the lawn mowers for integrity and completeness: if all parts are in place, if there is any visible damage. If everything is in order, proceed with the preparation of the fuel mixture. In the instructions for the tool, you will find clear recommendations from the manufacturer regarding the type of fuel and oil suitable for your model, and the proportions of the components for the fuel mixture. In this case, it is very convenient to use a special container on which a scale with marks for each component is already applied. Remember, the oil to fuel ratio should be as close as possible to the requirements of your tool. Preparing and filling the engine with the fuel mixture will take you a few minutes.
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:
- Place the mower on a flat, horizontal surface;
- Move the choke control lever to the closed position;
- We pump fuel into the carburetor with several strokes of the primer;
- Turn on the ignition switch;
- Smoothly pull out the starting cord until you feel resistance;
- Then make 3. 4 sharp jerks with the cord until the lawn mower starts;
- After starting, open the air damper.
If the mower does not start or stalls the first time, slightly open the air damper on the carburetor and try to start again.
Ratio of gasoline and trimmer oil
To properly dilute the oil with gasoline for the trimmer fuel mixture, always follow the recommendations on the oil container. Most often, this proportion is 1:50. Any high-quality 2-stroke oil is suitable for mixing.
Starting your lawn mower for the first time will require special care and attention from you. It does not matter if this tool is new or you are putting it into operation after a long period of inactivity, following the simple rules of the first start-up will help you avoid damage to the device.
How to start a Stihl lawn mower
The trimmer greatly simplifies the control of weeds and excess grass in your garden. Using gasoline, battery and electric scythes is much more productive and ergonomic than working with a conventional scythe. In order for your trimmer to remain in working order longer, you should know the basic rules of its operation and care.
How to start the lawn mower for the first time?
A cold engine is started according to the following algorithm. Close the air damper first. By the way, you can find the necessary lever by the symbols on the unit body. Now we turn on the ignition on the handle and, using the manual fuel pump, which is available in most models, pump the fuel mixture. Usually, after three to five clicks, it is already shown in the pump, which means that the trimmer is ready to start.
To start the device, you must select a stable and level surface. The first time you pull the starter rope smoothly until you feel resistance, then 3-5 sharp jerks should be made, after which the engine should start working. If you can do this on your first try, be sure to open the choke. Don’t be discouraged if your attempt fails. In any case, open the choke so that the fuel mixture does not flood the spark plug and continue to pull the cord out until the engine starts. Sometimes the first start-up process can take up to 15 jerks.
Before starting operation, the engine must be warmed up at idle speed. To do this, you need to press the throttle lever once. If desired, it can be stopped using the required button. In order to start the already warmed-up engine of the lawn mowers, it is enough to press the start and pull the starting cable several times.
Follow the instructions and you will never have problems starting and operating a properly functioning lawn mower.
1st start-up and running-in of lawn mowers
The correct 1st start-up and running-in of the lawn mower are very fundamental steps when first using a new tool. On the one hand, they allow you to save the engine life of the internal combustion engine, laid down by the manufacturer, because at this step, the moving parts and parts are lapped. On the other hand, the first necessary abilities of working with a trimmer are acquired, if we are talking about the first tool in life.
Preparing the correct fuel mixture
Before you start running in a new lawn mower engine, you need to properly prepare the fuel mixture. As is clear for two-stroke engines, it is prepared from a special two-stroke oil and gasoline, taken in certain ratios. You can find out the proportions from the annotation that came with the tool, or on the lubricant label. From the annotation, you will also find out the recommended type of fuel, as well as the recommended type of engine oil.
Prepare fuel in small quantities, sufficient for one mowing of grass. Use special plastic cans for fuel, or separate glass or metal dishes. How to start properly how to start a Stihl trimmer repair with your own. Oil is best drawn up with a medical syringe.
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 discrepancy 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?
Air and fuel filter
Contamination of these units of lawn mowers is fraught with either their complete replacement, or thorough cleaning. When replacing the fuel filter, do not leave the suction pipe unprotected. this can cause a breakdown in the engine piston system.

What to do if the petrol trimmer is not gaining momentum?
If you have once purchased a trimmer that runs on gasoline, then you probably had to deal with the problem of turning on the trimmer, as well as with such a problem as the petrol trimmer does not pick up speed.
Stihl FS 55. cold start and some grass cutting
That is why this article was created.
So, what to do if the trimmer, which has been working for you for more than a year, suddenly just stops picking up speed, and the engine simply stalls? In this case, you and I should consider a number of problems associated with stopping the operation of the motor.
The motor can stall under various circumstances. Why the lawn mower turns. I can’t get it off the ground. And it is gaining momentum from the floor. Sometimes the reason for the improper operation of the trimmer, running on gasoline, is a clogged air filter.
It is the filter that is one of the most important reasons why the gasoline trimmer may stop working.
Various debris very often gets into it, dust particles get there, which also clog the filter, so it needs to be cleaned and washed every month, and maybe more often, it all depends on what power the petrol trimmer has, as well as how much often you use this device.
The numbers mean the following: one part of the oil takes fifty parts of gasoline. Hence: 1000 ml (1 liter of gasoline) is divided by 50, we get 20 ml, that is, 1:50.
Thus, you can calculate the composition of the fuel mixture (gasoline / oil) in any proportions. To add oil to gasoline not “by eye”, you can advise to take a 20 ml medical syringe, draw oil into it and “inject” into a container for preparing a fuel mixture.
See the trimmer instructions for the continuous running time of the lawn mower. On average, we mow for 15-20 minutes, after which we turn off the trimmer and let it cool for 3-5 minutes. Weather conditions also affect the duration of continuous operation. In hot weather, when mowing tall grass, thickets of weeds, under heavy load, the trimmer overheats faster.
Many lawnmower problems arise from improperly prepared fuel mixtures. In two-stroke engines, lubrication is carried out with a special oil (not ordinary engine oil!), Mixed with gasoline. If the oil is not mixed with gasoline, the lawn mower will quickly fail. Mix the oil / gasoline in the proportion indicated in the trimmer instructions. Usually it is 1:40 or 1:50.
The question often arises: the proportion of 1:50 is how much oil and gasoline?
the lawn mower does not pick up speed, the cause of the malfunction and its elimination
1st start-up of the newest lawn mowers. Removed the mesh from the muffler, began to work.
Another one is the presence of malfunctions in the power system.
In this case, the lawn mower will stall at idle speed. The Champion trimmer stalls at RPM. Lawn Mower Goodluck 4300 stalls on video revs. The mower will stall when you press the gas. The lawn mower stalls at high rpm. A misalignment or improper adjustment of the carburetor can lead to problems with the power system.
Vibrations that occur during the operation of the lawn mowers can lead to misalignment.
Incorrect adjustment of lawn mowers can be corrected simply by adjusting it in accordance with the requirements specified in the instruction manual.
In addition, sometimes gasoline trimmers can stall due to the fact that the valve located in the gas tank cap is simply clogged or stuck.
To find out, try using a scythe by loosening the gas cap.
If the device works properly in this mode, clean the valve.
Why is the Chinese lawn mower not picking up speed??
The trimmer does not gain momentum, a very frequent discrepancy and of course does not always have the usual solution.
If you put a cable instead of a fishing line, without the possibility of releasing it, securely fixing the two ends of the cable and cutting them off by welding (a drop of melted metal keeps the cable from unraveling). Such a tool “knocks down” the grass at a time. Cuts off shoots up to about a finger thick. Not as afraid of stones as a disc. There is, however, a problem: when worn, pieces of cable thread break off, and these twisted wires remain in place of the mowing. Stepping on them can cause injury.
But the pieces of the cable left on the field are half the trouble. The fishing line, breaking off, weakens the dynamic shocks on the transmission and the engine, the cable does not give such an opportunity. The result is rapid wear on lawn mowers.
Also, the ignition coil may be punctured in electrical equipment. In this case, the lawn mower will not start, or it will start and work intermittently, and then it stalls, or it will not start at all when it is hot.
You can check the coil’s serviceability in the same way as when checking the spark: we unscrew the candle, lean it against the trimmer body. If there is no spark when you jerk the starter, or it appears every other time, you need to change the coil.
In no case should you store gasoline in a plastic container from under water. When mixing the fuel mixture, a static charge accumulates, you can “catch” a spark.
Therefore, at gas stations it is not allowed to fill gasoline in plastic cans, only in metal ones. Before pouring gasoline into a metal canister, it is better to put it on the ground, this way static is removed from the body.
But there are situations when simple manipulations with the lawn mower do not help. The engine still won’t start. In this case, we are going to check the power supply and ignition system, guided by the rule “the engine does not work if there is nothing to burn or nothing to ignite”.
