How to tension a chain on a saw

Setting the correct chain tension on the saw. Proper chain tension on the saw is an important point. This allows for more productive work on cutting wood and increases the life of the tool. When adjusting the chain tension, the following points should be considered. The chain should not sag and should not be too tight. To tighten the chain: 1. Loosen the nut securing the saw bar with the chain. 2. Adjust the chain tension with the adjusting bolt. 3. Secure the saw bar in the optimum position with the fixing nut. When working with a power tool, it is necessary to remember the safety rules and use protective equipment during work: gloves, safety glasses, etc. YouTube Channel Monetization Partner:

How to handle a saw? (Useless tips)

After prolonged storage, especially in an unheated room, condensation may form in the saw, which leads to a short circuit at startup. To avoid this, put the saw for a day or two in a dry and warm room before working.

For the preparation of firewood, it is more expedient to use gasoline models, since they have more power and a number of revolutions (8& 9 thousand rpm.) Than electric models (about 5 thousand rpm.). In addition, electric chainsaws cannot be used without stopping for a long time.

If the saw is not equipped with a thermal control system for the engine, then the insulation of the armature windings may melt and a short circuit will occur. If the system is installed, it will literally turn off the engine cooling tool literally every minute.

Electric models are recommended for use for carpentry or small, cosmetic work to care for the garden and cottage plot.

For cooling it is necessary to lay the tool aside more often. By the way, most household class saws are able to work continuously for a few minutes.

Electric models require careful monitoring of current stability, especially when using low-power saws. In our electric networks (especially in rural areas) voltage drops are frequent, and the magnitude of such surges on weekends and holidays can reach 15& 20%. By the way, the more powerful the motor, the less sensitive the instrument is to voltage stability.

When working with a saw, you must constantly pay attention to the saw blade or chain. If during operation the saw heats up very quickly and quickly, this indicates, first of all, about poor sharpening of the teeth.

In order for the fishing line to be cut when working with a circular saw, it turns out that the edges of the casing must be in contact with the surface of the wood and abut against it when working. If it is difficult to advance the saw blade over the wood mass, you must first, without stopping the work, move it a few centimeters back along the cut, and then slowly again direct the movement of the saw along the same line.

Care requires not only the tool itself, but also its accessories. For example, a chain after each working day needs to be re-edited and sharpened. In addition, if the tool is not equipped with an automatic chain lubrication (there are, of course, not many of these), you should lower the saw bar more often in a bucket of oil.

A properly sharpened and adjusted saw cuts itself; almost no additional efforts are necessary to it. After work, it is necessary to remove the saw blade or chain, wipe it off, clean it with kerosene and put it in a special box until next use.

Tool storage is a topic for another discussion. Particular care should be taken to save battery models that must be kept in a dry and warm place at an ambient temperature of no higher than 50 degrees Celsius, otherwise the battery may be damaged.

The service life of the Nickel-Cadmium battery is maximum when operating in temperature conditions from 10 degrees Celsius to 35& 40 degrees. Of course, you should not leave the tool in direct sunlight, and even more so in the rain.

Saw is not just a dangerous tool, but an extremely dangerous one, therefore security issues should be given constant and increased attention. When working with a circular saw, it is necessary, first of all, to check the serviceability of the fastening of parts and wiring, the saw itself must be grounded.

Saw, for example, boards can only be in a dry room. Never start work near an open source of water, in a damp or humid place.

The saw blade must be firmly fixed, which must be checked before starting work. Speaking of circular saws, it is also necessary to especially note: each model is designed to use a disk of one specific diameter.

It is basically impossible to install a larger disk, and a smaller disk is unacceptable for safety reasons: in this case, a gap is formed between the disk and the protective casing, in which a finger can enter. And since the disk rotation speed is very high, the guarantee to stay without a finger is almost one hundred percent.

How to choose a saw?

At any cottage, the saw will be a great addition to the basic set of tools. Therefore, the question arises: how to choose a saw?

Before you buy a saw you need to decide what kind of work it will be used.

The most optimal type will be a chain saw, which in most cases is very convenient in operation compared to its gasoline counterpart.

The main advantages of an electric saw

The saw has several advantages that make it an indispensable tool in the household:

  • a chainsaw is much cheaper than a gasoline saw. In addition, the operation of an electric mechanism will be much cheaper;
  • this tool is considered easy to use, because it does not require specific skills in working with internal combustion engines;
  • this tool is considered to be environmentally friendly, since it does not emit harmful exhausts into the atmosphere during its operation;
  • The saw is convenient to use indoors.
  • saws are divided into: circular saw, chain device, electric hacksaw and saber type saw.

    Before choosing a specific brand of electric saw for a summer residence, special attention should be paid to the following parameters and technical characteristics of the equipment.

    Based on the value of these parameters, based on the technical characteristics, the final decision is made on the acquisition of a particular brand of electric saw. Characteristics that you need to adhere to when buying a tool:

    • tool engine power;
    • engine location;
    • engine starting system;
    • chain brake, saw chain;
    • chain tension system.

    Saw performance is directly dependent on engine power. We must not forget that the voltage drop in the network happens quite often, this leads to a loss of engine power and its overheating. All this can lead to sad consequences. Therefore, it is better to choose a tool that has a maximum power margin. Restrictive conditions in this case may be the weight of the equipment, its dimensions and, of course, price. Here, each buyer should focus on their financial capabilities and preferences.

    If we talk about the location of the electric motor, then saws are widespread, in which the motor is transverse. not ideal from the point of view of balancing. Such saws can be operated in a vertical plane. Saws, in which the engine is located longitudinally, are more expensive, but are considered more ergonomic, they are perfectly balanced, they are quite convenient to work in any plane. Therefore, the choice of an electric saw for a summer residence should depend, first of all, on the operations that it will perform.

    Mandatory in this equipment is the presence of an interlock.

    This factor is related to safety.

    Basic saw systems

    Comparison table of characteristics of chain saws.

    The soft start system of the tool engine allows you to protect the electric motor, the transmission of the saw from shock loads. This is due to the fact that braking, engine starts are the most extreme modes of operation. At the moment of switching on, maximum currents flow through the winding, which negatively affect the saw resource. This system has the ability to limit the starting current for the gradual acceleration of the motor.

    The saw design has a special thermal relay that protects the engine from possible overheating. If the engine temperature in working condition exceeds the set threshold, the protection system will disconnect the tool from the mains.

    During the operation of the chain saw, a so-called “back strike”, which occurs when the end of the tire touches the wood surface, is considered a very dangerous moment. This situation is prevented by a chain brake activated by a guard (it is at the user’s hand). This mechanism helps prevent accidents and accidents.

    The latest models of electric saws use low-profile chains, which have lower performance compared to a high profile. The advantage of this type of chain is that the tool with it is not so prone to vibration, which greatly increases the level of safety.

    The saw lubrication system operates in automatic mode, which uses an oil pump that can be turned on and off at the same time as pressing the “Start” button on the saw. This option allows you to save oil, and also increases the convenience of tool maintenance. Therefore, the owner can only control the oil level in the tank, adding it as necessary.

    It is preferable to choose an electric saw with a simplified tension system, which does not require the use of a special tool for fixing the tire. To tighten the chain, you need to loosen the nut by hand, and then slide the tire using the slider.
