Choice of "combat friend" - chainsaw should be technically justified. For what specific purposes does the saw need to come in handy, is it worth it to spend significant funds for its maintenance? Maybe it makes sense to dispense with a modest technical parameters, but a workable model. And again the advice of the home Master will help with the choice.

Chainsaws models
It is known that the following models of saws exist:
- domestic
- professional
- semi-professional.
When choosing a chainsaw chain one should initially be guided by its purpose.
The most common misconception is the wrong target operation of the chainsaw model. If you intend to use the saw blade for eight hours, the purchase of a semi-professional tool will be justified. If the saw blade is needed from time to time to cut the bushes or dry wood for routine maintenance, then you can use a household saw tool.
The chainsaws produced by the manufacturer can be used for sawing wood. From units of building designation they differ in engine life, increased resistance to overload and protection. You can buy a chainsaw cheaply, but it should not be used as a professional tool.
To find out what the saw tool is capable of, its characteristics and the duration of the working life, it is recommended to study the information of the chainsaw instructions.

Chainsaw device and operating principle
Models chainsaw, both semiprofessional and household purpose are an aggregate consisting of the main nodes:
- housing with electric motor
- chain saw bar
- systems of brake and antivibration.
In the work of chainsaws involved: an internal combustion engine, transmitting gearbox and a closed hub-roller chain, moving along the saw bar. Technical parameters are: engine power and volume, length of saw bar and volume of fuel tank.
Naturally, the parameters of the chainsaw chains will differ from the parameters of the household saw blade. To determine the user-specific characteristics of the tool, it is recommended to familiarize yourself with the catalog of chainsaws and customer reviews.
From household Husqvarna to semi-professional STIHL
The smallest model of household chainsaw is Husqvarna 137. The little girl is not able to work full-time.
But for the requirements of safety, ergonomics and functionality, such an "amateur" tool practically does not differ from professional units in any way. Compared with other household chainsaws, Husqvarna has several advantages:
- the anti-vibration system, which is based on the principle of two masses
- low exhaust level
- optimized unit management
- low fuel consumption
- lateral tension of the profile chain.
The owner of an engine with a power of up to 2.2 kW and an engine capacity of 36.3 cm3, a short tire up to 38 cm of the chainsaw Husqvarna 137 has an easy start. The secret is in the softening spring of the starter. Models of household saws are equipped with a standard saw bar of 45 cm with a chain, which can be replaced by 35-40 cm. However, the saw chain also has an amateur level.
In addition, the household tool at a relatively low cost is equipped with a primer for fuel pumping, which provides an easy start and economical fuel consumption.
Naturally, household saws are Oscar owners with a simple felling and sawing wood, yielding in the nomination "the best" for a professional instrument.
Hunter's notes - complete STIHL
Chainsaws models STIHL are considered semi-professional and professional and are widely used for the needs of forestry. The high capacity of aggregates with a capacity of up to 6.4 kW with an engine capacity of 35.2 to 121.6 cm3 makes it possible to produce thin and mature timber.
The design of saw chains of semi-professional units does not require much time for adjustment and balancing. These parameters already provide a balanced center of gravity of the saw and its light weight.
For example, a chainsaw 250 calipers with an engine capacity of 45.4 cm3 weighing 4.6 kg will allow you to cope with sawing in a private house, hunting or traveling.
A short saw bar up to 40 cm, an anti-vibration and braking system, no problems with start-up with four modes of operation means that you are just dreaming of rest now. Two days of hard work in the logging process will make it possible to achieve complete calm.
In addition, the debugged lubrication system of the profile chain with a variable oil pump will provide a good economy.
The carburetor compensator stabilizes engine power and fuel consumption, minimizing the maintenance costs of the unit.
Professional chainsaws STIHL deservedly considered the best chainsaw in its segment. Does not frighten even the significant price of the instrument.
An additional advantage of chainsaw from STIHL is the possibility of easy transportation and easy storage.
How to make a real choice of household, semi-professional or professional chainsaw will tell this video.
But any technique in the process of intensive work has the property of physical wear, which leads to the failure of the unit and the subsequent repair of chainsaws.
Repair of chainsaws
The design features of the saw tool assume the replacement of the units of the unit, namely:
- carburettor and air filter
- fuel tank and oil pump
- ignition and starter systems
- clutch and crankshaft
- silencer and crankcase
- piston group
- chain brake.
Recall that the overload of elements and chainsaw chains are allowed sporadically. Therefore, the correct purpose of the saw blade will extend the life of the saw blade.
