How to prepare a mix for a lawnmower

How to correctly operate a gasoline brushcutter

Garden trimmer. very useful equipment for those who own land. Garden trimmers are also called brushcutters. They will be petrol or electric. Care of the electric grass trimmers is very simple, but the petrol trimmer owners need to know a lot of nuances. In this article we will describe in details how to start the trimmer, run it in, as well as how to mow the grass properly with it.

Before you start working with the brushcutter you need to do a few steps to prepare the machine for work.

Oil mixture

Before you start running in the engine of a new lawnmower, you must prepare a quality fuel mix. A suitable paste and gasoline will be required for a two-stroke engine. Use a mixing ratio which you can find out in the trimmer manual. The manual also contains information on fuel and grease recommended for a particular model.

Do not prepare oil in reserve, calculate the quantity which will suffice for one mowing. Use a plastic canister for the fuel. A glass or metal container will also work. You will need an ordinary syringe to conveniently take up the mastic.

It happens that producers of tools and masticate specify different proportions, that is why the owners of gasoline trimmers do not know which one to choose. Typically the manual for the trimmer shows the ratio 1:25, but the manual for the mastic is 1:50. Which will be the best?

Specialists believe that if the instruction manual for the trimmer specifies the ratio 1:25 or 1:30, the manufacturer just does not know which oil will be used. But the great amount of oil in the Skoda tool, because it does not burn out completely, leaving a small amount of carbon, which then clog the details of the engine. It is preferable to give priority to the proportion recommended by the manufacturer of the mastic.

First start of the trimmer

When the trimmer is filled with fuel, you can start the tool. To do this, proceed as follows:

• Lay the tool on a flat surface.
• Use a suitable roller to close the air-tight seal.
• Pump some fuel into the carburetor using primer.
• Turn on the ignition switch.
• Do not pull the starter cord until you feel an obstruction.
• After that make a few strong jerks until the lawnmower does not start.
• When the trimmer starts, open the air vent.

If the lawnmower could not be started, or if it immediately stops, try opening the air vent on the carburetor a little.

Lawn and lawn mowers. Preparation of fuel mixture. Changing the oil in the lawn mower engine

When choosing a means to care for the grass in the garden or dacha site, the owner faces a choice. what to buy. a lawn mower (electric mower) or a wheel mower. Abundance of information in the Internet and sellers’ advice make a perfect mess in a potential buyer’s head, based not only on experience (including negative), but also on prejudice and outright ignorance.

A lawn mower is for strong men only! (like Schwarzenegger).

lawnmower is a two-stroke gasoline engine with the power of 1-2 liters.с., on one end of the tube. And on the other end is the cutting element, a disc or a spool with a fishing line. The total weight of this device is several kilograms. And the suspension point is made in such a way that even a fragile girl can handle a gasoline lawnmower. Grasshopper is very well balanced.

Fueling two-stroke engines and making the fuel mixture are wonders of alchemy, inaccessible to mere mortals

Two-stroke engines require for their power not just gasoline, but a fuel mixture of gasoline and oil (special for two-stroke engines). It’s absolutely not in short supply, two-stroke motor oil is sold at any auto parts store and any place that sells these very lawn mowers Ask the salesman and he will lead you to a shelf with these oils. The choice is overwhelming.

To make a “gasoline-oil” mix is no more complicated than tucking mayonnaise in a salad Typically, the oil to gasoline ratio in the mix ( 1:32 to 1:35) is indicated on the mower (or chainsaw). This ratio is for mineral oils. But now for two-stroke engines, they are very hard to find, except for motorcycle engine oils. For small packaged oils for gardening equipment. almost only synthetic oils. They have a 1:50 ratio (it usually says so on the package). You have to follow the advice on the oil package!

To prepare the fuel mixture, you take a canister of 5 liters of gasoline, for example, and pour 100 ml of oil into it. That is all the secret. You will be blended for the whole season. Not enough. repeat the procedure Pour this mixture into the gas tank and no more problems.

For your Husqvarna mower you have to buy only Husqvarna oil

Husqvarna doesn’t have their own refineries. It’s a different business. That is why they buy the oil for two strokes from the refinery in tanks, pack it in small cans and label it “Husqvarna” And they charge the ignorant extra 2-3 for this label. Another company, STIHL, for example, buys the same oil from the same factory and labels it as STIHLand they’re charging fools 2 to 3 bucks for it too Any two-stroke oil is good for any two-stroke engine!

Wheeled lawnmowers are only for perfectly flat lawns.

Not at all I used to think so too on my completely unplanned lawn. The wheeled lawnmower turns out to be an excellent contour mower. The only obstacle is anthills that can be removed with a spade. And uneven terrain is handled very well with a wheeled mower. Especially if it has an adjustable cutting height. You set it to maximum and check your lawn. Where the blade touches the ground, you can also work with a shovel.

The lawn mower’s cutting performance is several times better than a hand lawn mower. And steering is like pushing a stroller. You just walk over and guide it. Especially if the mower is self-propelled. Even kids can handle it.

Wheeled lawnmowers have 4-stroke and their maintenance. difficult as a car.

Wheel mowers usually have a four-stroke engine. The fundamental difference between the four-stroke engines and two-stroke engines is the presence of a sump, in which there is oil for engine lubrication. That is why a 4-stroke engine does not require a fuel mixture of oil and gasoline, you only need to fill the tank with gasoline. This fact is presented by some dishonest sellers as an advantage, e.g. “there is no need to bother with fuel mixture preparation”. At the same time they “nicely” omit such a detail, as the need for at least annual oil change in the crankcase of a wheeled lawnmower. The procedure is not complicated, much easier than changing oil in a car, but more complicated than preparing the fuel mix. Generally speaking, the oil in the lawnmower‘s crankcase needs to be changed about every 50 hours of operation. The lawnmower has no oil filter and therefore the oil is not cleaned there. That’s what makes oil changes so frequent. On the other hand. 50 hours of mower work a season is a very long run time.

The process of changing the oil in a ride-on lawnmower is easy. Before changing the oil it is advised to let the mower run for 10-15 minutes, so the oil warms up and becomes more fluid.

The design of any lawnmower has a special screw that covers the drain hole from the engine crankcase. It is usually located under the oil filler neck and measuring cup of the crankcase. (marked with an arrow in the photo).

Install the mower with the inclination towards the drainage hole, placing a wooden block or a brick under the cover on the opposite side. After that the screw-cap is unscrewed. That the oil would not spill on the lawnmower housing, from a plastic bottle cut a chute in which the oil will flow into the vessel. It is advisable to empty the gasoline from the gas tank before changing the oil.

After that they unscrew the screw. stopper and let the oil drain out by tilting the lawnmower. When the oil has run out, screw it back in. Fill up with fresh oil via the measuring jug. Lawn mowers are often advised to use 10W40 viscosity oil, mineral or semi-synthetic.

The inexperienced owner of garden machinery, of course, tends to almost worship the new purchased technique, up to the fetishism. He wants to fill it with better gasoline and more expensive oil. This is a typical mistake and causes mowing appliances to fail very quickly!

The thing is, this gardening equipment is made in “streams”.е. The oil in the brushcutter is used in common stock, not specialty materials. The clearances in the engines are “conveyor belt”, nobody lapped anything there. That’s why you can’t use oil that is thinner than the manufacturer’s recommendation. It just won’t hold in the gaps between the parts.

The brushcutter is filled with

In order for the mixture to be properly distributed in the fuel system of the device, a simple instruction must be followed. How to properly fuel a gasoline trimmer for grass:

• Hold the brushcutter horizontally with the filler neck up and pour in the correct amount of fuel;
• Never fill the grass trimmer too much: Always check the fuel level at the top mark;
• Do not spill fuel on the ground or on the body of the tool;
• Before you start the engine, keep a safe distance from the fuel containers;
• If there was old fuel in the tank before refueling the new one, you must completely empty the gas tank.

Fueling your brushcutter with a 2-stroke engine

To refuel this type of gasoline trimmer, follow the instructions already described. Check the oil ratio and make sure it does not spill on the housing. Make sure that the gas tank is not overfilled, because then the engine will be unstable.

Filling up brushcutters with four-stroke engines

The main difference is that grass trimmers with this type of engine are not fueled with a mixture of oil. It is necessary to separately pour AI-92 and separately motor oil. General rules for filling the tank are similar to those already described above.

How to mix oil and petrol for 2-stroke engine

The peculiarity of two-stroke engines is that fuel is filled into the tank together with oil. Each refueling before operating the equipment requires the preparation of a fuel mixture with respect to the proportions. How to do it right? From our article you will learn how to dilute gasoline for a chainsaw, grass trimmer and other garden tools.

Instructions for preparing the fuel mixture

To operate your gardening equipment, it is recommended to buy unleaded gasoline. Otherwise there is a risk of engine failure. Manufacturers advise fuel with an octane number not lower than AI-90, better AI-92 or AI-95. Individual recommendations for your tool can be found in the instruction manual. At the gas station, pour the right amount of fuel into the canister. It is desirable to take a metal: in such a container does not occur static electricity from friction, which increases the safety of use.

Buy branded oils for two-stroke engines, preferably API-TB or API-TC. The manufacturer should indicate the recommended brands in the manual to the tool. Also consider their composition. Mineral oils are suitable for use in warm weather. Synthetic oils are better, they are less viscous and can be used even in cold weather. Semi-synthetics are mineral oils with improved qualities, versatile for any season. For the temperature limit of operation, see the package. Also note the volume. It is not the proportion of gasoline and chainsaw oil that matters, but how much fuel mixture you need for one filling and how often you will be working with the tool. If in your arsenal in addition to the saw also trimmer for grass or gasoline shears and you several times a week use one or the other tool, it makes sense to buy a large canister of oil in the volume of 3. 5 liters. For several mowing operations during the gardening season it is enough to take a bottle of 1 liter.

When you start working with a tool, the question always arises, how much oil to add to gasoline for a chainsaw or grass trimmer. It’s important to remember that for two-stroke engines the ratio is 1:50, i.e.е. 5 litres of fuel = 100 ml of oil. Why it is important to follow the proportions? Excess oil causes soot deposits on pistons and spark plugs, and lack of oil reduces the lubricating power of the fuel mixture, which leads to burrs on pistons and increases the risk of engine damage.

It is easiest to observe the proportions of gasoline and oil for a chainsaw, using measuring containers. They have a scale and marks on them so you can easily find your way around. Before you pour the gasoline and oil in, make sure the container is clean. Avoid getting any water or dirt in, as this can affect the quality of the fuel mixture. First fill petrol to the correct level, then add oil to the correct level. To mix them, tilt the container several times. Liquids will quickly mix and the mixture will become homogenous in color, e.g., green or red (depending on oil composition).

Wearing gloves is recommended to protect your hands from gasoline and oil. Also remember the elementary rules of fire safety. Mix fluids outdoors so gasoline vapors do not accumulate indoors. Do not smoke while working and exclude other factors that can cause ignition of flammable liquids.

Add the fuel mixture you have prepared and fill in the fuel tank and close the cap tightly. If you put more mixture than you can use at one time, empty it into a separate canister for storage or leave it in the mixing tank. The main thing is to keep the cap tightly closed. The ready mixture can be stored for two weeks and used for refueling without risk to the engine. The only condition is that you do not leave it in the fuel tank. If the tool will not be used for a long time. use up the leftovers completely or drain.

Now you know how to dilute gasoline for a chainsaw so as not to harm the engine. Try and do it yourself. After you prepare the fuel mixture several times you will know how many components are needed so you won’t have any extra mixture. You can buy everything you need in our online store. Used genuine oils will keep your power tool for a long time.

What is the right lubricant for the grass trimmer gear?

The tines are under constant strain during operation. Gear lubricant for brushcutter gearboxes is tailored to the individual parameters of the unit used.

Factors to consider:

• Mark. Most brands offer their own lubricants or recommend suitable lubricating compounds;
• Viscosity. There are three main groups. high viscosity, plastic compounds for universal use, and solid compounds that soften during operation.
• Lubricant consumption. Users often rely on personal experience and expert advice about the period of operation of the gearbox between lubrications. Temperature range is also important. Optimum operating temperature at 40 °C.

A gearbox can run on a lubricant compound with these components:

• Antiwear additives without toxic lead;
• Graphite or molybdenum disulfide in solid lubricants;
• On mineral (inorganic) oils, which are distinguished by a high degree of purity.

The list of optimal products for all indicators includes numerous lithium greases of foreign domestic production. Do not exclude the brands that are recommended by the manufacturer of the lawnmower.

How to properly lubricate?

It is not difficult to lubricate the grass trimmer gearbox if you follow simple tips. There is a special hole on top of the housing, which is plugged with a screw. It should be unscrewed and about two milliliters of grease should be injected through the hole on the tube. If the packaging is large, you can use a disposable medical syringe. After screwing back the screw.

It is recommended to repeat the procedure every 12 hours of operation of the brushcutter. Also the grease is renewed or replaced during routine maintenance work (gear wheels are cleaned and washed before the summer season), repairs of the unit, preparing the grasshopper for storage for the winter.

If the chain saw has been disassembled, old lubricant must be removed from all parts, even if there are no signs of oxidation or dirt. After the new lubricant is applied, check the shaft by hand to make sure the lubricant is evenly distributed throughout the gearbox.

What parts need more attention?

• Flywheel. Often it is covered with grass residues, which create a certain resistance during operation;
• Start coil latch. When starting the drive, it touches the grooves on the flywheel, provoking mechanical wear, as well as mechanochemical corrosion due to the contact of different materials (aluminum flywheel, steel dog);
• Bearings. The compacted walls can wear down and grease residues start to stick out. The unit vibrates vigorously under load. This is a problem with Chinese trimmers, that’s why it is often necessary to replace the original bearing unit for a better quality.

Learn how to dilute gasoline and grass trimmer oil if you under or overfill the oil

If you have bought a grass trimmer, lawn mower, brush cutter, chainsaw and other types of equipment, you probably know that they use two-stroke motors as power units. These motors do not run on pure gasoline like four-stroke motors, but on a mixture of gasoline and oil. In what proportion should you dilute gasoline with oil for grass trimmer. this is the question every dacha owner asks himself before preparing the tool for work. Let’s understand this question in detail, as the dilution of gasoline with oil for grass trimmer affects the service life of the tool, and improper preparation of the mixture, will lead to rapid wear of the engine. How dangerous is the excessive or insufficient amount of oil in gasoline for grass trimmer:

• If the gasoline will be diluted with a large amount of oil (above the norm), it will lead not only to a large amount of smoke, but also to the formation of soot on the cylinder walls and a drop in power. This soot will cause piston wear and tear which will be diagnosed by a decrease in performance
• If the gasoline does not contain enough oil in the grass trimmer, it is even more dangerous. After all, the working mechanisms of the engine will not be lubricated in a sufficient amount, which will eventually lead to their rapid wear (there is a rapid destruction of piston rings and jamming of the motor). If there is not enough oil in petrol in the grass trimmer, the wear of the motor will happen dozens of times faster

To avoid having to pay for mistakes at the cost of an engine overhaul or buying a new tool, you must fill the tank with fuel of the correct consistency from the first day. You can find out the ratio in the instruction manual of the tool, because the models of different manufacturers may give different recommendations. Usually this ratio is as follows:

• 1 to 25 or 40 grams of two-stroke oil per liter of gasoline
• 1 to 40 or 25-30 grams of grease per 1 liter of gasoline
• 1 to 50. this is 20 grams of oil per liter of gasoline

The standard value is 1:50 (indicated on canisters of oil for two-stroke engines), but it has to be taken as a last resort, because the manufacturers have indicated the recommended ratio, and if you do not follow it, the service life of the two-stroke engine will be reduced.

In addition to observing the proportions, you must also learn how to prepare the mixture. After all, the option of adding oil to the gas tank, is categorically contraindicated, although some do so. If you have purchased a grass trimmer or lawn mower, you will need the consumables you will use to prepare the mixture. The instructions for preparing the fuel mixture in the grass trimmer are as follows:

Prepare gasoline and two-stroke oil, based on the above recommendations on the choice of lubricant and fuel Additionally for the preparation of the mixture you need to take a container or container. Usually a plastic bottle is used for this purpose, which should be chosen accordingly. It must be clean on the inside. It is not advisable to use a container from milk, beer, or other beverages

It is very important that the container has a whole value of volume, that is 1 or 2 liters, so you don’t have to calculate how much oil to pour in a bottle of 1.5, 1.3 or 1.25 liter because you can easily go wrong That you also need a syringe, which is used as a measuring instrument for dosing the oil. For such purposes, an ordinary medical syringe of 10 cc or more is suitable

It is desirable that the syringe has a precise measuring scale After preparing the necessary materials, you can proceed to the preparation

• To begin with, fill the plastic container. The reservoir is filled two fingers under, not full, so that the oil can fit
• Pour the required amount of two-stroke oil into the syringe and pour it into the bottle with the filled gasoline. This is the way to do it, not the other way around
• After adding the lubricant to the bottle, you need to close it tightly with the cap and stir. However, be aware that oils labeled “pre-mix” need to be stirred. If the oil can is marked “self-mix” then there is no need to shake the can, and after mixing the substances, you can pour them into the tank of the tool

After preparing the fuel mixture for the grass trimmer, it remains to refuel the tool, and get to work. How to properly fuel grass trimmers, lawn mowers, chainsaws and other types of motor equipment, let’s consider in detail.

This is interesting! ДOnly fresh gasoline is used to dilute and use in the trimmer.

Recommendations for storing the finished fuel mixture for grass trimmer

After filling up the grass trimmer, many people save the remaining mixture in the bottle until the next time. Sometimes this next time comes not soon, and stretches to the next year. Do not keep the mixture ready for such a long time, since the oil decomposes. After preparing the mixture, you need to use it up for 1-2 weeks. In addition, it is also not allowed to store the tool for a long time with the fuel mixture poured into the tank, because the effect will be similar. To prevent unforeseen circumstances, it is advisable to consider the following guidelines for storing a ready-to-use gasoline/oil mixture:

• Prepare the fuel mixture in the amount that will be used. If you do not know how much fuel you use, then it is better to prepare less
• If fuel mixture remains in the grass trimmer’s tank (when the tool is hidden until the next season), it must be completely used up or drained
• Before refilling the cooked mixture into the tank, you need to stir it thoroughly
• Store the finished mixture in a tightly screwed container, and in a place limited to sunlight

If all recommendations are followed, the service life of the grass trimmer will be no less than that specified in the manual. The use of quality consumables paired with the observance of recommendations on the preparation of the mixture in the grass trimmer, will result in a long and effective service of the gasoline tool.

Fuel mixture for grass trimmer: practical recommendations

A lawn mower is as essential to your home or garden as a single-axle tractor or chainsaw. Unpretentious in operation the tool, demanding only the quality of the fuel mixture and its own cleanliness. And while there are usually no misunderstandings about keeping the mower clean, some users occasionally have questions about the composition of the fuel. How to dilute gasoline with oil for grass trimmer to keep its effective performance for as long as possible? What are the consequences of too much or not enough oil in the gasoline? The answers to these simple questions lie on the surface: you need to understand the role of lubricant in the work of a two-stroke engine.

The engine life of a brushcutter depends on how accurately you follow the recommended proportions of oil to petrol mixture. The fact is that the fuel mixture enters the cylinders as a petrol-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of a variety of parts in the cylinder. If it suddenly turns out that there is not enough oil, and somewhere it will not be enough at all, the parts that are in contact with each other will start to damage each other. As a result, scoring, scratches and chips are formed that will lead to complete or partial engine failure (for example, it may seize up).

In the opposite case, when too much oil enters the engine, it does not have time to burn completely, depositing on the walls of the cylinder and turning over time into solid particles. coke, slag and the like. As you can guess, this also leads to engine failure. The most important thing is that you shouldn’t allow even a single oil deficiency. It is better to overfill a little oil 10 times than to underfill just once. Often just once is all it takes to break the engine.

Choice of chain oil

Besides the engine, for which you already know the proportions of oil and gasoline for your STIHL chain saw, there is another important part with lots of moving parts. the chain. It is lubricated not with engine oil but with chain oil. It has very different properties and is cheaper.

Only manufacturer’s oils that are recommended in the manual are used for new tools. Otherwise, if the saw breaks down, it will be taken out of warranty because of improper use. It is important to note that the oils from the manufacturer are of really high quality. After the end of the warranty period, you can use any engine oil, making its replacement twice a year.
