Comparison Sequoia SEC 2014 vs Eltos PC-2650

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.

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.

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.

The protective mechanism of the chainsaw, which almost instantly stops the chain in a dangerous situation. Most often, it is activated during kickback or when pressing the front hand guard. The main purpose of this function is to reduce chain rotation time and minimize the risk of serious injury. The chain brake is especially important when trimming branches, cutting firewood, and any work where the saw may suddenly jerk upward or sideways.

The design or set of special elements that reduce the transmission of vibrations from the engine and cutting part to the user's hands. Anti-vibration system makes work noticeably more comfortable, especially if the saw is used not just for a couple of minutes, but longer and regularly.

Thus, the tool tires the hands and forearms less, and the cutting itself often feels more controlled. It is especially useful in chainsaws and powerful reciprocating saws, where vibrations are more pronounced. In practice, this is convenient when sawing firewood, trimming branches, working on beams, or during prolonged demolition, where extra shaking quickly becomes a hindrance.

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.

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.
