Chainsaw techniques. How to saw trees correctly.

When developing a chain saw, Husqvarna experts always take into account the opinions of professionals that operate the product daily at logging sites. Our goal. Transfer their expertise to new models to make the machine even better from the customer’s point of view

You have your chainsaw, and you are ready to start cutting wood and felled trees? It is better not to hurry, because only from aside work with a chainsaw seems easy, but to begin with you at least should know how to start it. Exactly how to start the chain saw, you can read below.

Of course, all the necessary requirements before starting can be read in the manual to the purchased chainsaw, but let’s mention them in this material as well. First of all make sure that you have a certain amount of gasoline in your chainsaw, diluted with the right proportions of two-stroke oil and that the chain tension is set correctly. Only after you are satisfied that all preparatory steps for the start are done, you can put the machine into operation.

So put the clutch lever in the “cold start” position, it’s usually the lowest position. When the lever is in this position make two or three attempts to start, do not be surprised, the saw should not start. Then move the lever to the “warmed up start” position and in this position start the saw. That way you will have a proper and easy start.

As soon as the chainsaw is started, it is necessary to slightly push the throttle lever, which should automatically return the lever to the operating position and the engine will idle. After that, the saw is ready to work.

How to use a chain saw: refueling

The question of how to properly fuel a chainsaw is the first thing to deal with. In most cases, the tool of this type (especially household and semi-professional) is equipped with a two-stroke internal combustion engine, which uses fuel diluted with oil. Manufacturer specifies the oil that should be added to the gasoline (it is necessary to follow this point without fail). Also the manufacturer specifies how much oil should be added to a chainsaw. And this point must be executed flawlessly.

The fact is that the lack of lubricant in the fuel leads to excessive piston friction, which, in turn, is fraught with their rapid wear and tear. If we talk about the excessive amount of oil in gasoline, it’s not so terrible. Although how to know: firstly, the chainsaw is worse to start and, secondly, the formation of fouling, which also greatly reduces the life of this tool.

How to prepare fuel for a chainsaw correctly? In principle, it’s not difficult. the most important thing is to have a measuring jug at hand. One for gasoline and one for oil. The last one is a standard measuring cup with graduations. A very important point is the choice of containers for cooking fuel. glass or metal containers will be ideal. Plastic drink bottles are absolutely contraindicated. Gasoline corrodes them, and all this debris ends up in the engine.

Features of refueling

It is recommended to fill the fuel tank through a funnel with a fine mesh filter that prevents water and small debris from getting into the fuel system.

This measure is compensated by flawless carburetor performance. In the body of the saw, in addition to the gas tank, there is another tank for the chain oil, to determine the correct throat will help the symbols on the cover.

A lubrication system feeds specialty oil into the work area to cool the saw headset and extend its life. Used-oil or other oil surrogates in the oil system impair the life of the pump, bar and saw chain, and chainsaw performance in general.

What is sawing?

The principle of electric and hand saws is the same: the teeth of the saw act as small sharp cutters that scrape away the material and then remove it from the kerf in the form of sawdust when the tool is in motion. Saw performance depends on the tooth angle and tooth pitch, which is the distance between the teeth along the length of the saw, also referred to as the slot.

It is better to make longitudinal kerf cuts in wood with large hollows to ensure swift sawdust removal from the kerf. Sawing hardwood and cross-cutting require saws with small slots. they are more effective for working with hard materials.

European saws operate with a pulling motion, i.e. when the saw is guided into the material. Japanese saws, on the other hand, have their teeth pointed toward the handle and work when they move toward you. This allows the saw blade to be very thin. Japanese saws make very precise cuts.

Ergonomics

Prolonged use of the saw requires a great deal of strength if the hand and the handle of the tool do not fit together. Excellent cutting quality is no longer difficult to achieve thanks to the modern structure of the saw teeth. However, even the modern tools can be very tiring if the saw’s handle is slippery, angular or simply too small for the craftsman.

So check the ergonomics of your saw before buying it by holding it in your hand for a few minutes. You always have control when you hold the saw firmly in your hand and your thumb tightly around the handle. Soft pads on the handle of hand saws are not necessary at all.

Preparation

Preparing the saw itself comes down to filling it with fuel mixture and oil to lubricate the cutting tool, and checking the chain tension. When pouring gasoline it is important not to spill it past the tank, and if this happens, you must carefully wipe the surfaces with clean cloths. The same goes for the oil.

The tension of the chain is very easy to check: it should not sag at the bottom of the boom. Then use your fingers to pull it up. if the chain is tight, the ends of the links should protrude out of the groove in the tensioning point. Be sure to check the ease of movement of the cutting element on the guide rail.

Before you work with a chainsaw you need to prepare the timber as well. For sawing firewood it is better to use a special goad in which the work to be sawn is placed (you can use one of the sticks as a deck). It is important to have a firm grip on the tree trunk when crosscutting. As for felling, determine the side in which the tree will be placed, clear a place for it. In general, it is more convenient to work with an assistant who will bring timber and hold it while cutting.

After the preparatory work it is possible to put the sawing process into action. Start the chainsaw in accordance with the manufacturer’s recommendations.

Longitudinal cutting

A forestry worker, as part of the Solo School video, will give a lesson to beginners in felling, taking as an example one of the most powerful models of Solo brand chain saws. First the teacher will make an overview of auxiliary tools, explain what to wash the air filter, how often to change the fuel filter, what to grease the pinion guide pinion, once every how many days to grease the needle bearing, change the spark plug, clean the grooves, cylinder ribs. The presenter will teach you how to sharpen the teeth in the wood, explaining what the coarse/small shavings indicate. The following demonstrates the guiding undercut, felling cut, lever method of limb trimming, opening up thick trunks. Information is duplicated on the screen in text format.

The prototype of the modern machine was not designed by a lumberjack or an inventor, but by the German physiologist Bernhard Hai. In 1830 he invented the osteotome, a surgical instrument for cutting through bone with movable cutting elements resembling the teeth of a hacksaw. They rotate with a special twist handle. Improved chainsaws have been in demand in the lumber industry since the advent of gasoline-powered engines. Other actuators have been used: pneumatic, electric, steam, mechanical.

Start the tool in the video

A procedure such as starting a chainsaw is not difficult if you are consistent and careful. The algorithm is as follows:

  • Place saw on a flat, stable surface so the chain does not touch anything.
  • Engage the chain brake by turning the knob away from you; otherwise, the chain will start turning as soon as you start.
  • If your model has a decompression valve, activate it.
  • Pull out the air damper lever.
  • Place the toe of your right foot on the rear handle, holding the front with your left hand. Quickly pull the starter cord several times until the engine sneezes. Sneeze? “That’s how it went.”.
  • Return the throttle lever to its original position and start the saw while continuing to pull the starter cord.

After starting the saw and warming up the motor, do not remove the fuse (brake) until you are ready to start sawing.

How to use the chainsaw

That’s it, after the above precautions, you can safely proceed to sawing the wood. Working with a chainsaw is not difficult at all, the main thing is to adhere to safety techniques. Skills with chain saws develop very quickly. Soon you’ll be cutting all types of wood yourself. quickly and safely.
