How to Start a Dolmar Ms 3360 Gas Trimmer

Well-groomed cut grass in the yard. always nice and beautiful. To give the lawn an even look, use trimmers. However, if you are just planning to purchase a device, then you probably wondered how to choose a trimmer. In this article you will find information about what types of trimmers are, as well as which one is best for each purpose.

Types of Grass Trimmers

There are 3 types of trimmers depending on the power. Electric, gasoline, as well as battery.

If you choose a device that will work silently for yourself, then an electric-powered device is definitely your choice. Representatives of this type of device are light and maneuverable. However, it is worthwhile to understand that such equipment is suitable for those areas where there is constant access to an outlet to which you can connect a trimmer.

Gasoline models are more powerful than electric or battery powered models. Thanks to their autonomy, they can work almost anywhere and anytime. The advantage of such a trimmer is the ability to not only mow soft grass, thick flower stems, but also small shrub stems.

Naturally, such a device is noisy, which not everyone will like.

The third type of trimmers is cordless. The models of this type are the least represented on the market due to low demand. The disadvantage of such trimmers is that the battery is bulky, and it lasts no more than 40 minutes.

How to choose

In order to choose the right trimmer for a summer house or garden, you need to clearly understand the goals and conditions in which the device will be used. This will help you choose a trimmer that will last more than one season.

Nutrition

The electric unit is suitable for women due to the ease and convenience of maneuvering. In addition, there are the largest number of electric trimmers on the market, so that you can choose a convenient option. Due to the fact that the device is powered from the network, it has low mobility, there is also a danger of cutting the wire by negligence.

Petrol powered trimmers use city services to keep lawns in order. Due to the fact that the tank with gasoline is attached to the device, it becomes heavier. Thus, not all owners of a summer cottage can cope with a trimmer.

There are also models with more battery power, but the price immediately rises so significantly that it becomes unprofitable to buy such a unit. However, if you have a small area, and you are worried about the environment, then the battery option is suitable for you.

Power

Power is the main criterion for choosing a device for mowing grass. Typically, power varies from 220 watts to 1800 watts. The most powerful representatives have a faster rotating knife, due to which they are able to process a larger area in a shorter period of time. Remember that with the power, the weight of the device also increases.

Models with low power (up to 700 W) are suitable for small areas with soft, non-rigid grass. If you have a need to mow a larger area that has rigid stems in the territory, give preference to models with a power of 900 watts or more.

Cutting width

The width of the cut directly affects how efficiently the plant will be cut in one pass. The most common sizes range from 20 cm to 42 cm. The larger the cut width, the more space the trimmer will cover in a shorter period of time.

For a summer cottage, it will be enough to purchase a trimmer with a cut width of about 26 cm.

Revs

Turns, as well as the width of the cut, affect the quality of mowing. This indicator indicates the number of rotations that will be completed in 1 minute. Cheap models have a maximum speed of 7 thousand, so on the box you often can’t even find this pointer. In devices with greater power, this figure can reach up to 12 thousand. In order to choose a trimmer for the garden, it will be enough to find a device with a speed of 6 thousand.

Diameter of fishing line

This marker shows how thick the stems of individual plants are capable of cutting equipment. Similarly to the width of the cut, the smaller the indicator, the more effort will be required to remove the lawn. The minimum diameter of the fishing line is 1.5 mm, the maximum is about 3.5 mm. It makes no sense to buy a trimmer with a larger fishing line diameter than 2 mm for a summer cottage, which requires maintaining the lawn in a tidy condition. If it is necessary to improve the area on which there are many weeds, then you can choose the diameter of the fishing line with a larger diameter.

Cutting system

The cutting system of the trimmer is the main element due to which it works. It can be made of strong metals or soft fishing line.

Thick knives will be the best option for groomed lawns. The fishing line is suitable in those places where there is a probability of contact of the cutting system with something other than the lawn. When hitting hard surfaces, the fishing line does not break like knives. However, thick grass can be a problem for them, as the grass will get stuck in the fishing line.

Type of fastening

Types of fastening almost do not differ, but amenities depend on them. The presence of one belt will be suitable for those situations when long mowing does not occur. Two belts are better suited for employees of urban landscaping services, as they will take on part of the vibration and distribute the load.

Hold comfort

This criterion includes both the number of straps, the shape and number of handles, and the balance of the unit. If you choose an electric grass trimmer in your own small garden, then one single handle will be enough, but if a large area is mowed or for a long time, it is better to give preference to a machine with two handles or with intersecting each other.

The location of the engine at the top of the handle is better for prolonged mowing than if it is located below. The lower it is, the more pressure is exerted on the back.

Tank volume and battery capacity

Well, when it is possible to fill the trimmer with gas so that it is enough for the whole mowing. Cheap trimmer models hold 300 ml of fuel and last about 20 minutes. A trimmer with a tank with a capacity of up to 1.5 liters is able to work for about one hour.

Autonomy and charging time

Battery models are lighter than gasoline and more autonomous than electric ones, however, the charge of such devices is not more than an hour. The indicator is measured in amperes. For example, 1 ampere per hour is enough for 15 minutes of continuous operation. However, to justify the battery models, we can say that they charge quickly.

Length adjustment

The bar. the continuation of the trimmer handle can be of several forms: D. maneuverable, J. safe, T. suitable for long continuous operation. There are also pull-out and non-extendable rods. The telescopic rod will increase its length by about 20%, which can play into the hands at a time when you need to reach hard-to-reach areas.

Comparison of gasoline and electric trimmers

Before choosing a gasoline or electric trimmer, you first need to understand for what purposes and operating conditions the device is purchased.

Gasoline trimmer is suitable in the following cases:

  • Dense stems are present on the lawn;
  • No access to the outlet;
  • There is a need to work for a long time;
  • The harmful gases emitted during the work are unimportant;
  • The presence of a strong person capable of holding a heavy apparatus.

Choose an electrical appliance if:

  • The grass on the plot is soft and uniform;
  • There is access to an electrical outlet;
  • Take care of the environment;
  • There is no need to work for a long time;
  • Light weight is important;
  • There are budget restrictions (electric models cost about 6 thousand rubles);
  • The presence of loud noise is scary.

Thus, to save the budget, you need to choose a light and environmentally friendly electric grass trimmer. But, in more severe conditions of grass stiffness and the inability to connect power nearby, you can not do without a more powerful gasoline model.

Conclusion

When choosing an apparatus for cutting grass, it is important to understand correctly for what conditions it is purchased. Due to the large offer on the market, you can choose for yourself the most acceptable and convenient option in the ratio of price and quality.

  2. Requirements
  3. Varieties
  4. Selection tips
  5. How to use?

Gas trimmers are some of the most popular grass mowing devices. They are easy to use, mobile, allow a person not to depend on the outlet and show excellent results in places of their use. But for the stable operation of the gas trimmer, quality supplies are needed. In particular, we are talking about gasoline and oil. It is about the last component that we will discuss in this article.

Appointment

Engine oil is a special mixture consisting of a solvent and additives that reduce friction. They form a certain viscosity and do not allow the composition to thicken when the temperature is lowered. Usually, oils are specially painted in various colors: green, red or blue. This allows them not to be confused.

Keep in mind that they may vary in composition, so oil for gas trimmers will be labeled “for gardening equipment”. In addition, it may still differ in labeling: “2T” or “4T”. The first is a two-stroke oil that is poured into the corresponding engine. And the second is intended for pouring into the crankcase.

Requirements

High-quality oil that can be poured into a gas trimmer must meet a number of requirements and standards to ensure reliable operation of the device and its performance. Oil should:

  • to provide increased wear resistance for various elements (in particular, the gearbox is particularly susceptible to this);
  • ensure the lowest possible smoke and exhaust gases;
  • Prevent premature ignition
  • mix well with gasoline when exposed to low temperatures;
  • have good viscosity and fluidity in various temperature ranges;
  • be as safe as possible in terms of environmental impact.

As already mentioned, two-stroke engine oil will differ from four-stroke formulations. It has higher power, which is why fuel for it is obtained by mixing a certain amount of gasoline and oil. For each lawn mowing ratio will be different. You can find out its value in the instructions for the device. These proportions must be observed with maximum accuracy. When adding additives, the type of motor must be considered.

If mineral oils are used, mixing should occur somewhere in the ratio of 1: 25, 30 or 35, depending on the type. If we are talking about a synthetic analogue, then the proportion will be 1: 50 or to 80. That is, a certain amount of oil dissolves in the volume of gasoline.

Varieties

The oil that is poured into the motor may vary in the method of preparation. According to this criterion, it happens:

  • mineral. this type is obtained during the processing of petroleum products;
  • synthetic. it is obtained during the processing or synthesis of gas;
  • semi-synthetic. this type has more advanced characteristics due to the introduction of synthetic-based components into it.

Lawn-mowing oil refers to formulations intended for use in air-cooled engines that have a combustion chamber volume of 50-200 cubic centimeters. In addition, any two-stroke oil can differ from analogues in additives, which give it certain additional characteristics. They are of the following types.

  • Antiwear. The main objective of the oil will be to reduce the wear of parts during operation of the device.
  • Antioxidant. They do not allow oxidation to occur and make it possible to maintain the performance of the oil for a long time.
  • Corrosion resistant. Their task is to prevent corrosion from forming on engine parts.
  • Friction modifiers. These additives can significantly reduce the coefficient of friction.

Recently, when purchasing oil for dilution with gasoline, users very often encounter the fact that special letter abbreviations are applied to canisters. These designations are performed as part of the API classification. Consider what types of oils exist in accordance with it.

  • TA applies to air-cooled lawn mowers, the engine capacity of which is not more than 50 cubic centimeters. It can be used not only for mowers, but also for mopeds, lawn mowers and other types of equipment. For a gas trimmer, this is the optimal solution.
  • TB is used to refuel a chainsaw, scooter, moped or motorcycle, the engine capacity of which does not exceed 200 cubic centimeters. It can also be used for refueling gas trimmers.
  • TC suitable for dilution with gasoline and pouring into a snowmobile, motorcycle and other types of equipment.
  • TD is for refueling boats, yachts and hoverboards.

But in addition to this classification, other FA-FD type letters are often found. It should be said that the API is an American standard that is applied in Europe. But there is a mismatch between European smoke emission standards and American. For this reason, additional lettering should also be taken into account.

  • FA can be used in countries where the law provides for minimal exhaust emissions. When using oil with this marking, faint smoke may be produced.
  • FB. can be used in countries where smoke and gas restrictions are much stricter. In this case, smoke will hardly be emitted.
  • FC. here appears smoke of a transparent color, which the human eye cannot notice.
  • FD. a special category of oils for 2-stroke engines, they do not create smoke at all. They have enhanced chemical properties. Typically, this oil is used for mixing with gasoline and subsequent refueling of boats and yachts.

In addition, oils come in two more categories:

  • Selfmix
  • Premix

In the first case, this will mean that it is necessary to carry out independent mixing, which does not require shaking, and in the second case, you will need to do it.

Selection tips

Now let’s try to understand how to choose high-quality oil for a trimmer that runs on gasoline. The main feature that you need to pay attention to is the alkaline number. This moment excludes the oxidation of parts in which friction is observed, and decelerates their deformation as much as possible. The more this compound is used, the faster it loses alkalinity and becomes more oxidized. The optimal indicator of acidity (PH) is a value of not less than 8-9 units.

The second important factor, which also has a major impact on the operation of the gas trimmer, is the viscosity of the oil. This characteristic determines the possibility of using the device at various temperatures. Summer brands of oils begin to thicken already with a minimum decrease in temperature.

The third point, the importance of which should not be minimized, is the flash point. This indicator should not be less than 225 degrees. Otherwise, the composition will burn out very quickly and the load on the piston group will begin to increase, which will cause its accelerated wear. In addition, oil for a 4-stroke engine is not suitable for a 2-stroke. Namely, the latter type of motors is used in the vast majority of lawn mowers.

If we talk about manufacturers, then you can make a small rating, which will allow you to navigate in the compositions offered by various manufacturers. For instance, stihl company It offers high-quality synthetic and mineral oils that have already established themselves as an excellent solution at any time of the year.

Considered very good Shell Helix Ultra Oil. Experts note its high characteristics and excellent alkalinity and viscosity. In addition, products of brands such as Oleo-Mac, Motul, Hammerflex, Echo. If we talk about products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than its foreign counterparts, but at the same time it has high quality and good technical characteristics.

How to use?

Information on the proportions of oil use was given above. We must say right away that you should not deviate from the indicated values ​​and dilute gasoline by eye. In the best case, you just need to change the oil, and in the worst you can’t avoid a motor breakdown.

It is important to be able to cook the mixture correctly. It is impossible to fill it in a gas tank. It is better to pour oil in a special container that already contains gasoline. A plastic mineral bottle is perfect for this. It is very important that it is clean, which is why beer or milk bottles will not work. And it is better that it be a liter or two-liter, since it will be difficult for many to calculate how much oil to fill in a 1.5-liter or 1.25-liter bottle. You will also need to have a syringe on hand, which will serve as a dosimeter. It is best to take a regular medical for 10 or more cubes.

Now step by step explain how to make good oil for a gas trimmer.

  1. First you need to know exactly what type of oil is required for a particular model of the braid, and also find out the exact ratio of gasoline and oil to create a mixture.
  2. Then you need to fill the container. The tank should not be filled with gasoline to the end, because the oil should also fit there;
  3. Now we collect the necessary amount of 2-stroke oil into the syringe and pour it into a bottle with gasoline. You can’t do the opposite, otherwise you will need to replace all the ingredients, and the mixture will need to be done again.
  4. Close the bottle with a lid and stir. It is important not to forget that stirring the mixture is necessary if there are Premix words on the oil bottle. If Selfmix is ​​written there, then after mixing the substances everything is poured into the tank.

Now it remains only to refuel the gas trimmer, and you can carry out the necessary work.
