Patriot grass trimmer

A huge role in the performance and durability of a gasoline trimmer for grass is played by oil, which protects the details of the cylinder.piston group from rapid wear.

In order for the lawn mower to delight its owner with trouble.free work, a competent approach to maintenance is needed. Currently, it is customary to distinguish between two main types of engine by the number of working tactes:

The principle of operation of two- and four-stroke engines

• two.stroke engines where oil is added directly to the fuel tank;
• four.stroke engines with a separate oil tank. An exception in this category is the STIHL 4-MIX motor, which works on an oil bosinzin mixture, but at the same time has 4 work tactes.

Nevertheless, most of the trimmers presented in our market are equipped with power units operating on a mixture previously prepared in a fuel tank.

Types of motor oils and their purpose

Oil for the engine of a gasoline trimmer for grass is a lubricant that serves to reduce wear between the rubbing nodes.

The composition of the oil includes residual hydrocarbons and various additives that improve the properties of the final product. To ensure the durable and reliable operation of the lawn mower, experts recommend the use of oils, which in their physicochemical properties correspond to this type of motor.

Today it is customary to distinguish between three main types of oils by the method of obtaining them:

• Minerals created in the process of distillation of hydrocarbons;
• Synthetic oils obtained by processing natural gas or synthesis;
• Semi.synthetic, including improved mineral oil with the addition of some synthetic components.

In order to prevent mixing of various types, the manufacturer adds dye to the oil, which shows the difference in the composition of the lubricant.

Lubricant system of two.stroke and four.stroke engines

Four.stroke engines are equipped with separate lubrication systems and preparation of the fuel mixture.

Therefore, the pump supplies oil directly to the rubbing surfaces, that is, the crankshaft bearing and the place of contact of the piston with the walls of the cylinder.

To do this, the lubricant is poured into a special container, from where it comes to the channels to the areas of increased friction.

In addition, through the crankshaft and connecting rod, the oil enters the piston and washes it, reducing the temperature and lubricating the walls of the cylinder.

Two.stroke engines are deprived of a separate lubricant system, but they also have a crankshaft bearing in need of reducing friction force.

In such power units, the fuel mixture first enters the crankcase, where the crankshaft bearing is located, and then under the influence of discharge passes by the piston, cooling it and lubricating the cylinder walls, enters the combustion chamber.

However, gasoline does not have lubricating properties, therefore, such devices are seasoned with a gasoline mixture, that is, with liquid combustible, to which a special oil was added.

The efficiency of the lubricant with the fuel mixture is much lower than with engine oil, so the life of the bearing of a two.stroke engine, which means the crankshaft and connecting rod, is noticeably less than the same part of the four.stroke engine.

In addition, a two.stroke lubrication system makes special requirements for the oil, because it should burn as much as possible in the cylinder and form a minimum of toxic substances.

What is the difference between oils for different types of engines?

The different principle of operation of the oil system forces the use of lubricants with different properties and characteristics.

In addition, in four.stroke engines the oil serves the whole season, and in two.stroke engines it lubricates the details, then burns in the cylinder, which also affects the requirements for it.

Four stroke

According to the principle of operation, the four.stroke power unit is completely identical to automobile internal combustion engines.

Therefore, the requirements for lubricating fluid are the same as for ordinary motor oil for high.speed car engines.

The main parameter of the lubricant for four.strokes is viscosity, which describes how fluid the oil will be at the operating temperature, and indicate the parameter with the letter “W” and the numbers before and after it.

The numbers in front of the letter describe the minimum negative temperature at which it retains its lubricant, but for trimmers this parameter is not relevant, because it is not used during frost.

The numbers after the letter describe the viscosity at operating temperature. Typically, for four.stroke trimmers, they take a lubricant 5W30 or 5W40.

Another relatively important oil parameter for four.stroke engines is the type of lubricant, that is:

Mineral oil is made by thermal distillation (distillation) of oil and heavy oil products. It is cheap, but has mediocre lubricants and low resistance to high temperatures.

Synthetic oil is obtained from various gases emerging from the Earth along with oil. It is much more expensive, but has noticeably better lubricant and resistance to high temperatures. Semi.synthetics is a mixture of both basics.

However, basic oils of any type have extremely mediocre characteristics, so they are modified using various additives (additives) that change the properties of the finished product.

over, the requirements for the clock depend on the characteristics of the motor and the conditions of its operation, however, trimmers engines work in noticeably more comfortable conditions than automobile, therefore, oil intended for any engine is suitable for them. For this reason, the API class is not indicated on the container with lubricant fluid for trimmers, that is, compliance with certain automobile engines.

Two.stroke

Since oil for such engines works only a few moments, after which it burns in the cylinder, it does not require the same resistance that is characteristic of the lubricant of four.stroke engines.

In addition, it should have a higher lubricant, because such oil comes to the bearing being very diluted gasoline.

Since all two-stroke engines of garden equipment work approximately in the same conditions, the oil for them has no divisions in viscosity or some classes.

Two.stroke oil is suitable for a trimmer for grass, even if it is written on the packaging or container that it is intended for the following two.stroke devices:

An important condition is complete combustion in the cylinder, otherwise the trimmer for the grass will greatly pollute the environment, and the smell of its exhaust will be extremely unpleasant.

That is why the incorrectly composed fuel mixture gives a thick dark or blue exhaust with a sharp unpleasant odor. The same effect appears when the apparatus with a faulty or non.configured engine/carburetor appears, as well as with strong encouraging.

If the motor does not start or works incorrectly

The reasons that the motor does not start with a two or four jerks of the manual starter cable can be:

Most often, this is due to the incorrectly executed trimmer for the grass, when the procedure is violated or some important point is not executed, so the launch is quite correctly carried out and the motor will work. If the mower is poorly started after storage, then most likely, old gasoline is exhausted, so it is enough to change it.

If the trimmer for the grass was not served for several seasons, then the poor launch can be due to dirty air or fuel filter, so it is enough to rinse or replace it.

If all actions are performed correctly, but there is no positive result, contact the workshop or independently diagnose or repair.

Advantages of a gasoline trimmer for grass

The gas mowing with a gasoline engine has several advantages:

• high power and performance;
• the possibility of refueling at any time of operation;
• the ability to use the nozzle. a rotor for cutting small trees or shrubs;
• mobility (the ability to use anywhere in the site or in the field).

A gasoline engine braids are available with a tank volume of 0.5 liters, 1 liter and 1.5 liters.

Choosing oil mushrooms

As mentioned above, oil mushrooms oil is necessary for lubricating the working units of the engine. The oily fluid when it enters inside spreads through the details, providing light sliding, durability and minimal wear of the technique.

Important! Oil for a 2-stroke engine is categorically not suitable for a 4-stroke engine.

The difference lies in the fact that when the 2-stroke engine is operated with gasoline, but the oil for a 4-stroke engine does not burn, but on the contrary, retains its physical and chemical characteristics.

Important! In no case should you pour car oil into the tank. Lubrices for cars and trucks are designed for water cooling mechanisms. And in the lawnmands, air cooling is used. Therefore, for garden equipment, their products are produced, focused on air cooling.

Lubricants for two.stroke engines

Manufacturers of lubricants always indicate the label or in the instructions for use for which types of engines this product is suitable. For two.stroke engines, you can purchase the following lubricants:

Oil for four.stroke engines

For engines of this type, lubricants with the marking SAE-30, SAE 20W-50 and SAE 10W-30 are ideal. The numbers and letters indicate the viscosity of the lubricant, as well as the weather conditions. For example, the SAE-30 and SAE 20W-50 are ideal for summer time, and SAE 10W-30 is best used in the winter or off-season. For all seasons, it is allowed to use oil marking 5W30. For four.stroke engines, preference is given to semi.synthetic or mineral products.

Removing and lubrication of the upper shaft of a trimmer for grass

First of all, we remove the lower part of the rod from the connecting coupling, and then disconnect the coupling from the upper part of the bar (here we are talking about a coupling connecting two halves of the bar).

Trimmer for PRorab-8406 grass with a detachable coupling and the lower part of the bar

Now the most interesting thing: on some videos, as on this, holding the ticks of the shaft with ticks, sticking out of the upper part of the bar from below, knock out it with blows on the rods from the rod along with the rolling bearing (here we are talking about the coupling connecting the upper and lower shafts). Some have a gas station with a collapsible bar, as in the video, a coupling connecting the upper and lower shafts, it is put into the rolling bearing.

With our trimmer Prorab-8406 and such a number will not pass like him. They do not have a rolling bearing, and the connecting coupling (sleeve) is a continuation of the shaft of the upper rod. A locking ring is installed in the upper part of this shaft, which must first be removed.

The place of fastening of the upper part of the bar to the clutch clutch body

• We turn off the central screw completely. It fixes the upper part of the bar, partially entering the hole drilled in it. We loosen the side clamping screws and remove the bar from the clutch clutch body.
• We put out the shaft from the upper part of the bar on ourselves how much the backlash allows to get to the stop ring and remove it. A special puller may be needed. We extract a locking ring.

Stop ring on the upper shaft Motokos

• Without a locking ring, the upper shaft is easily extracted from the bar from the opposite side. Lubricate it, not forgetting about the slots in the bushings (couplings) on the shaft of the bar and on the clutch shaft.
• The greased shaft is installed in place in the upper part of the rod and fixed with the locking ring. We insert the bar into the hole of the clutch clutch cover and combine the hole on the bar with the threaded opening of the fixing screw.
• We screw the fixing screw and fix the upper part of the trimmer rod for the grass with side screws in the clutch lid.
• Clean the connecting coupling of the bar from the garbage and install from below on the upper part of the bar.

I don’t have a puller, and I use two large stationery paper clips to extract a locking ring. Previously, they need to be straightened, on one side make a half.ring for the fingers, and on the other. bend small hooks.

In many videos, masters recommend using Shrus-4 grease, this is the best option. In its absence, to lubricate the shaft of the gas mowing rod, you can use Litol-24, which is focused on temperatures up to 130 ° C. But solidol, with the worst lubricants and working at temperatures up to 70 ° C, is not recommended to use.

However, if you urgently need to lubricate the shaft of the rod motorcosa, but there are no suitable materials, then solidol or even ordinary motor oil will be better than nothing at all.

Inspection of the reducer of the lawn mower and its lubrication

Checking the gearbox before starting a gasoline trimmer for grass must be carried out on a regular basis. The lack of lubrication or its small amount increases the friction of the gear gear of a gearbox operating at fairly high speeds. As a result, overheating and gears occurs. Motokosa gearbox fails. To prevent the occurrence of such a breakdown during operation and the regular inspection helps.

If, before the launch of a gasoline braid for grass, an insufficient amount of lubrication in the gearbox or its absence in the case is laid “litol”. To do this, it is necessary to unscrew the screw on the bend of the gear housing and the “lilest” in the amount of 1-2 ml.

Champion trimmers for grass

This company was originally American. Nevertheless, the United States still possess the rights to the brand, but the actual production is in China. In fact, all the pros and cons of this technique follow from this.

Consumers are impressive low, in addition to almost every “collapse”, you can find all the necessary supplies, as well as spare parts. Unlike products of better well.known manufacturers, almost half of the cost of the trimmer itself for the grass does not have to pay for components.

Reviews show that the problems can be solved independently, since the design of champion trimmers is quite simple. In addition, the engines are perfectly “refill” not too high quality gasoline, developing a very acceptable power, which is very important in our conditions.

Disadvantages of Champion

Like any cheap Chinese technique, the Champion Gasinzin trimmer has many negative moments. Buyers are often unhappy with the general quality of the assembly, which is rarely perfect. This is primarily due to the low quality of the plastic used, which is too fragile and hard, which causes the vibration and roar of a trimmer for the grass during operation.

Many complaints are caused by the quality of the linings on the handles: again they are too rude. Ergonomics are low, so do not put on thick gloves with prolonged work. Buttons and other controls that experienced gardeners prefer to replace more complex and reliable, cause the same complaints.

A rather large mass is criticized. In combination with strong vibration, this makes champion unusable women or gardeners with thin skin.

Choosing and using oil

In its design, the engine of the gasoline lawn mower differs from the car engine only by the number of cylinders and air cooling.

The closest analogue is mopes of mopeds, because they also have only one cylinder and air cooling. Therefore, the same oil is suitable for gasoline lawn mowers as for cars or mopeds that meet the requirements of the manufacturer for SAE API.

If the manufacturer did not indicate the parameters of the SAE and the API, then it is necessary to focus on the following values:

Sometimes manufacturers recommend an oil of a certain brand, but this is not due to the fact that it is better suited for this motor, but to earn a desire to earn either partnerships, because the manufacturer advertises its products or goods of their partners.

At the same time, such oil “for lawn mowers” ​​does not have any real advantages, because automobile engines operate in much more difficult modes, which means that the requirements for oil are much higher.

In addition, it is important to correctly choose the oil type, because it happens:

The choice of the basis depends on the age of the mowing and the presence of a carburetor:

• 20 years or more. only mineral.
• 0–20 years, carburetor. mineral or semi.synthetics.
• 10–20 years, fuel injection. semi.synthetics.
• 0–10 years, fuel injection. synthetics or semi.synthetics.

The use of properly selected oil and gasoline allows the gas mowing motor to very carefully spend their safety margins, so that their service life can be decades.

The main parameter that determines the choice of gasoline or oil is the recommendation of the manufacturer, which can be found in the instructions for the operation of the device.

If there are no instructions at hand, you can use the recommendations that you found in the article. This will help you decide what kind of fuel to fill and which oil is used for gasoline lawn mower, regardless of its brand and characteristics.

Varieties of motor oils, their purpose

Motor oil represents a special composition representing a solvent and additives that reduce friction that create suitable fluidity and prevent thickening when temperature decreases.

• minerals acquired during oil distillation;
• synthetic. synthesis or processing of natural gas;
• Semi.synthetic. improved mineral oil due to the input of the synthetic component.

For safety reasons, so as not to confuse products, the oil is painted in reddish, blue or green color. The assortment varies in composition, the user must purchase oil with marking: “for garden technology” 2t, if you need to prepare a mixture for a two.stroke engine, 4t for filling in a crankcase.

Synthetic and mineral oils have a different base, they cannot be connected. When switching to another type of oil, the system must be painfully washed.

Oil for the lawn mower should be treated by systematization of the vehicle oils created for air cooling engines with a combustion chamber of 50-200 cm 3 when choosing a product with a fundamental parameter is not the cost, but the protective characteristics for the motor of a certain brand. Therefore, first they purchase the recommended oil, in the absence they select similar in terms of indicators.

Determines the quality of the oil for the lawn mower alkaline number. Alkali neutralizes the process of oxidation of rubbing materials, slows down the destruction of the surface. When the oil becomes oxidized, it loses the protective characteristics. Ordinary pH of oil 8-9 units.

The fundamental indicator is viscosity. Therefore, there is winter, summer and all.season oil. What oil moutine oil does it depend, whether the user will work at minus temperature. Summer oils thicken even with insignificant cooling. The flash temperature indicates how the oil will burn out rapidly from the composition. Normal if this indicator is more than 225 s.

Use and oil value in a two.stroke engine

The work of the motor is associated with the friction of the moving parts of the cylinder and sleeve, cams, hinges. During the friction of the parts, the surface is heated, with the expansion. clogging. If in the gap between the conjugated parts there is a composition in a suitable proportion of oil and gasoline for the lawn mower, a number of troubles are removed:

• Details in the engine work with low friction, are less warming;
• The lubrication in the gaps prevents the corrosion of parts during prolonged storage, lenses particles purchased during friction;
• The life of the motor is lengthened.

Preparation of the mixture

Many novice users are sure that if you add oil oils to the fuel mixture more than necessary, it will benefit. This is not true. Uninhabited oil is not excreted from the engine with exhaust gases, but will settle inside in the form of soot. This plaque threatens the integrity of the piston. If you use the mixture with an excess of oil regularly, then the trimmer for the grass will be greatly smoked, and the drop in power is inevitable.

With a lack of oil, the trimmer for the grass will overheat, the piston rings will be destroyed and the piston jams. If the oil deficiency is insignificant, then the trimmer for the grass will work 30. 40% less than the resource. If the lubricant is not enough more than 20%, then the motor will jam after 20. 30 minutes of intensive work. Each instructions for the trimmer have proportions on how to dilute the fuel mixture. This is usually 1:25. 1:40 or 1:50. In practice, it looks like this:

• 1:25. 40 milliliters of oil per 1 liter of gasoline;
• 1:40. 25 milliliters of oil per 1 liter of gasoline;
• 1: 50. 20 milliliters of oil per 1 liter of gasoline.

By the table, you can determine how much oil is poured into a certain volume of pure fuel:

How to mix

If you do not have a special measuring canister with divisions that are included in the set of the Trammer deserving attention for the grass, or such a container has been lost, then use any suitable container. Better glass or metal. Plastic can also be used, but you need to choose a bottle with hard walls.

The capacity of the vessel should be a multiple of 1 liter. You can take a bottle and 1.5 liters, but practice shows that it is not very convenient. You also need a medical syringe, preferably 20. 50 milliliters. First, gasoline is poured into the container, then an accurate amount of oil is added (by volume). The procedure cannot be changed.

If you have Pre Mix oil, then you need to close the bottle or canister and turn it upside down several times and shake it hard. If Self Mix oil, then it will dissolve on its own. The prepared mixture must be used throughout the day. If you know how much fuel is the trimmer for grass for a certain amount of work (or time), then calculating the amount of the mixture is not difficult. Otherwise, before each refueling, dilute the new fuel so that the minimum amount remains until the end of the work.
