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.

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.

Chain speed

The maximum speed of the chain relative to the material that a saw of the appropriate design can provide (see "Device"). Higher speed allows to achieve faster and cleaner cuts, but requires more engine power; low speed, in turn, reduces productivity, but allows you to achieve good traction with a relatively low engine power. More detailed recommendations regarding this parameter can be found in special sources.

Noise level

The noise level produced by the saw during operation. Note that this parameter is rather approximate, because in fact, the “loudness of the work” depends not only on the tool, but also on the material being processed and the characteristics of the environment. Nevertheless, the data given in the characteristics make it possible to assess the comfort of working with the tool. The lower this indicator, the less discomfort the noise will cause, and at high values, even special hearing protection may be needed.

Note that the noise level is usually measured in decibels, and this unit is not linear: for example, a difference of 3 dB corresponds to a difference of 2 times, 10 dB — to 10 times. Therefore, it is easiest to evaluate the noise level using comparative tables. Here is a simplified version of such a table for the range in which modern saws operate:

70 dB — loud conversation of several people in close proximity;
75 dB — a cry in the immediate vicinity;
80 dB — truck engine, mechanical alarm ringing;
85 dB — loud scream;
90 dB — freight car at a distance of 7 – 10 m;
95 dB — subway car at a distance of 7 – 10 m;
100 dB — industrial shop;
110 dB — tractor engine;
120 dB — demolition hammer, thunder from a close lightning strike (pain threshold of auditory perception).

Oil tank volume

The volume of the oil tank provided in the tool.

In this case, we mean a tank from which oil is supplied to the saw chain (see "Device") to lubricate it during operation. In general, this is a reference parameter that allows you to estimate how much oil is needed for one refueling of the tool.

Size

General dimensions of the saw. For a stationary tool (see "Type"), this parameter determines primarily the amount of space that will be required for installation; problems with this can only arise in very tight spaces, so in most cases the dimensions of a stationary saw do not need to be given special attention. In the case of hand-held models, the small size makes it easier to work in hard-to-reach places and improves overall usability. On the other hand, a compact tool inevitably turns out to be low-power; and some jobs by definition require large, heavy saws, with large bar lengths or blade diameters.

Weight

The total weight of the tool. For petrol models (see "Power Source"), usually, dry weight is indicated, excluding fuel.

In general, it makes sense to pay attention to this parameter primarily when choosing a hand tool. At the same time, note that higher power, a more capacious battery or a capacious tank will inevitably affect weight. However, tools with similar characteristics can and do differ markedly in weight. And here it is worth considering that a lighter model will be more comfortable to work with, but weight reduction may affect reliability and/or cost. In addition, a more massive tool is more stable, it is not so prone to jerks under uneven loads. If we talk about specific numbers, then a weight of 3 kg or less is considered very light, 3–5 kg is relatively small, 5–7 kg is medium, 7–10 kg is significant, and some powerful tools (mainly gasoline) weigh and over 10 kg.

As for stationary saws, weight is of secondary importance for them — it mainly affects the ease of transportation.
