Power source

By type of power source, all modern saw can be divided into electric and gasoline. The common difference between them is that electrical units are more compact and lighter, less noisy, easy to maintain and do not produce exhaust gases, so they can be used indoors without restrictions. Petrol tools, in turn, combine high power and independence from power grids, but they are heavy, bulky, more difficult to operate and repair, more expensive (both in terms of their own cost and fuel price) and are generally designed for use outside premises. Therefore, most modern saw are made electric, which in turn can use different types of power:

- Power supply (230 V). Connection to a standard 230 V household network, in other words, a regular socket. This option can be used both in portable saw and in stationary tools of relatively low power (up to 3.5 kW). There are sockets almost everywhere where there is electricity at all, and the operating time of such units is almost unlimited (as long as there is voltage in the network). The main disadvantage of such a power supply is the presence of a power cord that does not allow you to go far from the outlet (and with a portable tool, you also have to make sure that the cord does not get under the canvas).

- Power supply (110 V). Tools powered in the American and Japanese manners - from power networks with a voltage of 110...V. Power tools with such an operating supply voltage are produced for the market of North and Central America, the Land of the Rising Sun, Saudi Arabia. Also, 110 V power grids are found in the UK. To avoid tool failure when connected to standard 230 V household networks, you will need an additional link in the face of a step-down transformer or a special 110 V converter.

- Power supply (400 V). Powered by a three-phase power supply with a voltage of 400 V. Such power is suitable even for high-power saw, but it is far from being available everywhere - basically a three-phase connection is available in workshops, workshops and other industrial premises. Therefore, this option is found exclusively in stationary tools (see "Type") of high power, for which a conventional socket is no longer enough.

- Accumulator. Powered by own battery. The main advantages of this option are mobility, the ability to work independently of sockets and the absence of a power cord that can interfere with work. On the other hand, such a power supply is not suitable for high-power saw, other things being equal, a cordless tool turns out to be noticeably heavier and more expensive than a mains one, and the operating time is limited by the battery charge. However, in most cases, the battery is made removable, which allows you to keep several batteries ready and change them as needed.

- Battery / power supply (230 V). Tools that allow two power options - from an outlet and from its own battery. See above for more details on each option, and their combination makes the saw as versatile as possible. So, if there are sockets nearby, you can work from the network, saving battery power (or even recharging it in the process), and if there is a problem with the sockets or the network cable interferes with work, you can switch to the battery. On the other hand, such versatility affects the price, and the tool itself still turns out to be more cumbersome and heavy than a purely network one.

Engine size

The volume of the engine of a gasoline saw (see "Power source"). On the one hand, the power and performance of the tool depend on this indicator, on the other hand, its weight, price and fuel consumption. Accordingly, it is necessary to choose a model taking into account the specifics of the planned work, and it does not always make sense to chase large volumes. In particular, for simple household tasks, an engine capacity of about 40 – 50 cm3 is considered quite sufficient, and in professional models this figure can exceed 100 cm3. More detailed selection recommendations can be found in special sources.

Engine location

The location of the motor in the electric portable saw (see "Type").

- Longitudinally. The longitudinal arrangement allows you to achieve a good balance, allowing you to work comfortably in different positions; this is especially true for cutting branches from trees and other similar work, where the cutting plane can be located at different angles. In addition, such a tool has a smaller width and a longer length, which can make it easier to work in hard-to-reach places. On the other hand, such saws are more expensive than cross-cut saws.

- Transversely. The transverse arrangement of the engine slightly worsens the balance compared to the longitudinal one and makes it difficult to saw along an inclined plane, at an angle to the vertical. In addition, the length of such saws is noticeably shorter. However, for the simplest work with sawing from top to bottom, they are no worse than longitudinal ones, but they are much cheaper. Yes, and a small length in some cases can also be a virtue.

Power

Saw motor power in watts. For petrol tools (see "Power Source"), horsepower is additionally indicated, see below for details.

The higher the power, the better the tool is suitable for voluminous work and hard materials, the greater the depth of cut it can provide and the easier it can cope with significant loads. In addition, for different types of saws and different types of materials, the actual power values \u200b\u200bcan also be different. For example, a power of 2.5 – 3 kW is actually the limit for chain saws, but in chain saws this is an average figure, among such tools there are models of 3 – 4 kW and even more. Detailed selection recommendations for various cases can be found in special sources.

Power

The power of the saw engine expressed in horsepower (hp). This designation is traditionally used in gasoline models (see "Power Source") along with watts; 1 HP ≈ 735 W.

For more information about power, see the paragraph of the same name above.

Idle speed

The speed of rotation of the engine in a saw with an internal combustion engine (see "Power") with no load on the blade and with the speed controller fully released (set to minimum). Theoretically, the lower the idle speed, the lower the fuel consumption without load (ceteris paribus); however, the difference between modern chainsaws is usually so insignificant that this parameter is more of a reference than a real practical value.

No load speed

The highest speed that the saw engine is capable of delivering in normal operation.

We emphasize that this parameter should not be confused with the maximum disk speed (see below) — here we are talking exclusively about the speed of rotation of the motor shaft. It can be specified for all types of saws, not only for models using discs. However, in general, engine speed is more of a reference than really significant information. In fact, it is needed mainly for some specific tool maintenance tasks; when choosing, it is better to focus on indicators that are more “close to life” — engine power, cutting depth, chain / tape speed or disk speed, etc.

Bar/blade size

The largest tyre size (in chain saws) or disc (in circular saws and some others, see "Device") that is allowed for this tool. Tyres are sized by working length, rims by diameter.

A larger bar/wheel allows for deeper cuts but requires more powerful motors. Therefore, this parameter cannot be exceeded — this can lead to an overload of the engine with all the corresponding troubles. However, in many models with a disc it is physically impossible to install a nozzle with a diameter larger than the maximum allowable.

Also note that saws with similar bar/blade sizes may differ in maximum depth of cut (mostly due to differences in design or power). As for the specific dimensions, they depend on the type of saw (see "Device"). For example, large discs of 450 – 500 mm are found exclusively in stationary chain saws, the maximum figure for cutting models is 400 – 450 mm, for trimming — 300 – 350 mm, and sizes of 500 – 550 mm or more clearly indicate that speech It's about a chainsaw chainsaw bar. Detailed recommendations regarding the choice of a tool for a given size can be found in special sources.

Chain pitch

Regular chain pitch for which the chain saw is designed (see "Device"). A step is the distance between two adjacent chain teeth; the greater this distance, the higher the productivity of the saw, however, for a large step, higher power is required, and the cut is rougher. Therefore, this parameter largely determines the class of the saw and the specifics of the work for which it is designed. The current standard options are:

— 1/4". The smallest size, found in a low power tool — 1-1.5 hp. It has not received wide popularity due to poor performance.

0.325 ". One of the most popular options among amateur-class tools. Saws for such a chain have a power of up to 3 – 3.5 hp, they are suitable for both cutting branches and felling trees of small thickness.

3/8 ". He is 0.375". Slightly larger pitch than 0.325" is better suited for rough scale work. Also considered a household and semi-professional option, very popular.

— 0.404 ". The largest tooth pitch in modern chain saws. Rare, used in the most powerful professional tools designed for heavy work — for example, logging.

Note that it is allowed to install chains on saws with a finer pitch than the regular one, but not with a larger one. The latter is fraught not only with a decrease in the quality of work, but also with a critical increase in loads, with the possibility of tool breakage.
