How to choose a good power saw: what to look at before buying a unit?

How To Remove The Chain From A Makita Electric Saw

Rest in the country can hardly be called passive, then you need to build a gazebo, then make a bench, then remove old trees from the garden, sawing them into neat blanks to create a decor. In addition to the usual hand tools for wood plane, chisel, hammer, jigsaw, many owners have more serious equipment, such as an electric saw for wood. With its help, not only a porch can be built a whole house.

Chain tension adjustment

In the process of work, it will definitely be necessary to tighten the circuit on the bus from time to time, since it begins to sag from constant voltage. Of course, more convenient are those models where the tensioning system is thought out. For example, the device of the Makita UC4020A household electric saw is such that the chain can be installed and adjusted without disassembly and additional tools. There is a small lever in the body panel with which you can quickly tension the chain.

STIHL has equipped its products with a quick chain tensioning system. To do this, it is enough to loosen the cover fastening nut and adjust the chain using the wheel

Ergonomics of the unit

If the tool is used quite often, when choosing an electric saw, many pay attention to the location of the motor. It comes in two versions, longitudinal and transverse. Experts believe that it is much easier to work with a saw with the engine along the tire. In addition, longitudinal units have better balancing.

Electric tool advantages

Both an electric saw and its gasoline counterpart are good for garden and summer cottage work, but many still choose the first option. Why is he so attractive?

The power tool, indeed, has a whole list of advantages:

  • Does not require constant material costs for fuel gasoline;
  • Easy to use and maintain;
  • Makes less noise during operation than a chainsaw;
  • Clean from an environmental point of view, works without exhaust gases;
  • Allows for cutting indoors;
  • It works equally well, despite the climatic features (the gasoline analogue has problems with starting in frosty weather).

If the power source becomes unattainable, a cordless chain saw, such as the Makita BUC122Z (price RUB 9,000-10,000), comes in handy. Battery and charger must be purchased separately

Types of electric saws

If you need to cut a variety of materials of plywood, wood, plastic, chipboard, metal pipes and sheets, you should purchase a circular (circular) electric saw. Cutting is done with a rotating saw blade, and there are specific types of blades for each material. There are two versions of models, manual and fixed, attached to the bed.

A sufficiently versatile tool is a reciprocating electric saw, which is often used for cutting in hard-to-reach places. It is convenient for roofing and installation work. The working element is a file, the length of which varies from 0.1 m to 0.35 m. It produces oscillatory or translational movements.

Smooth, neat, even curly cut can be made with a jigsaw. It works equally well with ceramics, wood, laminate and metal. The file (working blade) of a jigsaw is indispensable if you need to cut a round hole or make a curved cut.

The best electric saws for giving are recognized as chain aggregates, the main active element of which is a bus with a chain stretched over it. It is easy to use, relatively compact, and does not require fuel mixture preparation. Almost all gardening work can be done with its help: to knock down an old tree, cut off branches and branches, saw a trunk. It is good for carpentry and construction, especially in confined spaces.

When working with an electric chain saw on the street, you must follow the safety rules. For example, the tool cannot be used when it rains, a short circuit is possible

Engine power

This is one of the most important indicators. For gardening work, a tool with a power of 1000 W to 2100 W is suitable, but it is better to purchase a stronger unit. The fact is that powerful electric saws respond more adequately to voltage drops in the power grid, therefore, they will last longer. For example, the engine of the popular CHAMPION 420 model has a power of 2000 W, that is, with small voltage fluctuations (200-224 V), it will remain operational and will not allow critical overheating. In addition, an indicator from 2000 W is a guarantee that in an extreme situation, when a large amount of work is required, the engine will withstand the load.

Chain for an electric saw. Review, choice, care.

One of the main parts of the electric saw, which directly performs the sawing, is the chain on the electric saw. Chains on power saws and chainsaws are practically indistinguishable from each other and are made from one blank chain material, which is cut and assembled according to a specific number of teeth that is used in this chain saw. A Makita electric saw chain, for example, is matched in the same way as a Husqvarna saw chain. The main thing is to pay attention not only to the manufacturer, but also to the parameters.

Types of chains of electric saws

Chains for electric saws are divided into two main types: longitudinal chains and transverse chains, which, respectively, are designed for sawing wood along the fibers or across them. Their difference is mainly in the angle of attack of the cutting link.

How to properly put a chain on a Makita electric saw

Varieties of saw links

Links in chains can be of three types: cutting, connecting and driving (shanks). They are connected to each other with rivets. The teeth in the chains are left-handed and right-handed. They are installed one at a time; material of manufacture. High-alloy chromium-nickel steel. In addition, the saw chains are equipped with cutting depth stops.

Depending on the size of the cutting teeth and the depth gauge, the chains are divided into:

  • Low profile with less clearance; less effective, but at the same time safer due to the fact that they are less prone to kickbacks (saw rebound), as a result of which the saw can break out of the hands and cause injury;
  • High profile with a large clearance; are less safe and are therefore only recommended for experienced users, while only low-profile chains are permitted on household saws.

    The main parameters of chains for an electric saw are as follows:

  • The number of links. Each chain on an electric saw is designed for saw bars of certain lengths.
  • Chain step. Determines the distance between the rivets connecting the links (more specifically, the distance between the first and third rivets is halved). The larger the chain link pitch, the greater the performance of the chain, but also the higher the load on the saw.
  • Link shank thickness. Should match the thickness of the bar groove.
  • Cutting depth. Sawing speed and productivity depend on it.
  • Cutting tooth profile height. Saws, depending on this parameter, are divided into low-profile and high-profile. The shape of the tooth profile can be rounded, semi-chisel, chisel and with carbide plates.

    How to sharpen a chain saw correctly

    Perhaps, the question of how to sharpen an electric saw chain is worth separately. If you bought a quality chain from a good manufacturer, such as a Makita power saw chain. Such a chain will require sharpening much later than a lower quality and cheaper one. Sharpening is done using a special sharpening machine; but if it is not there, at home the chain should be corrected with a cylindrical file. First sharpen the cutting teeth: place the sharpening template on the chain and sharpen with a gentle motion, pushing forward at an angle to the bar. The same number of movements should go to each tooth. File one tooth on the right, one. Left. Sharpen the teeth to the same length using the blunt one. In any case, if you are in doubt about how to sharpen the chain of an electric saw, consult a specialist.

    Electric saw bars

    When choosing it for an electric saw, you should focus on the following indicators:

  • Material;
  • Length and width;
  • The depth and width of the groove;
  • Chain lubrication method;
  • The number of teeth on the driven gear.

Selection of the bar and chain for the electric saw

As one of the key elements in the design of an electric chain saw along with the armature (motor), the chain and the bar are closely related to each other and actively participate in the process of work. Therefore, the need for their repair and replacement also arises quite often. In the article, we will briefly go over the main parameters and description of these elements, consider a chain from one of the well-known manufacturers on the Russian market.

Electric saw chains

The chain is one of the main working parts of an electric saw, therefore it needs careful care and timely maintenance. When choosing, you should adhere to certain rules:

  • When changing a part included in the sprocket-tire-chain link, remember the compatibility of spare parts, buy those that are recommended by the manufacturer.
  • It should be selected, taking into account what kind of work you will do with it. The more power is required, the larger the link pitch is required. Link pitch is expressed in inches. By today’s standards, this is 3/8; 0.325; 0.404 in.
  • The length should be suitable for the tire size. When chain slack occurs as a result of work, you just need to remove one or two links.

The teeth differ in their parameters, this should be taken into account. The rake angle of the tooth, made up by the planes of the sliding surface and the end blade, ranges from 60 to 88 degrees. The back angle has the following parameters; its tilt angle is 5060 degrees. By sharpening this value is corrected to the required values. Sharpening to an arbitrary angle should never be sharpened; you need to follow proven standards and angle values ​​for each chain.

You can replace the chain yourself. To do this, you need:

  • Move the flap, release the brake.
  • Use a screwdriver to turn the tension bolt, unscrew the nut, loosen the chain.
  • Remove the cover and separate the tire from the gear.
  • Remove the chain and replace it. After that, do all the steps in reverse order. The tightening should be done carefully, avoiding jerks.

Makita chains for electric saw

The Makita company has been producing electrical equipment since 1958 and today is a recognized leader in the Russian market for professional power tools. Unfortunately, there are no factories of this company, so everything is supplied through the official representatives of Russia abroad. Let’s take a look at some of the technical characteristics of chains for power tools from this company. Makita saw link pitch is 0.325 or 3/8 inch. The number of links in the chain varies in a wide range of values ​​from 40 to 96. This manufacturer equips some models with an automatic lubrication system, which automatically reduces labor costs during chain maintenance. This manufacturer is distinguished by a high price for its products, so you can purchase a chain for your tool starting from 30. E. And ending with 60 cu. E. The most widely used models diverge in price near the 40 mark. E.

Consider the shape of the tire. Consider tires from well-known chain saw manufacturers

Interskol, despite a wide range of manufactured tools, it does not have its own production. When replacing parts, Oregon counterparts are used in 16 and 14-inch versions. The company produces tires for angle grinders in two sizes: 800 x 210, 5 x 200, 5 and 1400 x 210, 5 x 200.5 mm.

Makita manufactures tires for its equipment. Electric saws are equipped with tires in sizes 250, 350, 400, 450, 500 mm. Battery-powered saws are equipped with 115 and 250 mm bars.

Bosch chain saws are equipped with products of the following dimensions: 300, 350, 400 mm.

Stihl divides tires into several classes according to the values ​​of the friction force. The Rollmatic brand has low values ​​of this parameter, for professional work, the Duromatic brand is needed, figure cutting is carried out using the Carving brand.

It will often be difficult for an inexperienced user to find a bar and chain for an electric hand saw. The purpose of this article is to clarify some of the issues that arise in the selection process, to give a brief description of these structural elements. It is clear that within the framework of this article we were not able to fully cover all the existing problems, but we tried to touch on the key concepts and solutions and give the most concise and understandable presentation.
