Recently, the popularity and availability of chainsaws really increased, because the price became more affordable for ordinary gardeners.Just remember, the lower the price - the more trouble there chainsaw.The breakdown can, of course, be prevented if timely preventive maintenance take place.Extend the effective operation of the instrument for a long time, you can, if done correctly repair.

Purpose chainsaws Chainsaw refers
to such tools, which are very difficult to accurately position.This can be explained only by the fact that the use of chainsaws is now so universal th
Initially chainsaw is a powerful but at the same time expensive and heavy professional equipment, which is primarily designed for felling.However, today a chainsaw - no longer just a tool exclusively for professional loggers.Without it, it is absolutely impossible to do with the repair and construction of wooden buildings, zagotavlivaya wood and trimming trees.
For those who prefer to work alone in the garden and take care of a private home, it is also necessary.Chainsaw is now - no doubt a high-performance alternative to hand-saw and ax, especially if you cut down trees or cut the boards.It turns out that a chainsaw is familiar to almost every handyman.
Species chainsaws by type
significantly increased the use of chainsaws, and this leads to the fact that there are so many different models of the instrument.Conventionally, chainsaws can be divided by type or by application.By type of household are distinguished, professional and semi-professional chainsaw.
Usually professional chainsaws used by those who work for a long time and maintains a tool "for slaughter": it is the builders and loggers.This professional saws differ a great resource, its performance and the highest level of vibration protection and well-balanced body with a fairly comfortable handles - for this you need a saw to work every day.
For buyers important in this instrument not only performance but also durability.Another important requirement - it is, of course, require minimal maintenance, because the data used chainsaws in those places that from the nearest service are hundreds of kilometers away.
why design must be such as to be able to figure out on their own with little problem.Cheap this technique can not be, but it's worth the money.For example, if a fault chainsaw calm still happen, you can even fix them yourself.
Household Household Model
chainsaw use "in the yard."You can even take a sawing logs for firewood.Of course, this technique is much cheaper and easier to constructively enough professional.These saws are typically used rarely, from one case to another, so that any significant improvements that enhance resource unit in this case is simply not needed.
Manufacturers are trying, as much as possible to simplify any structure to reduce the cost of the instrument and make it available for a wide range of consumers.However, among domestic chainsaws sometimes there are models of so-called "top of the range" - it is for wealthy buyers who can afford it.Semi
Semi chainsaw - a compromise version of the previous types.They have all the parameters of medium: no matter the price, the service life or capacity.Such tools are sometimes called farmers because designed to work not so much intense as regular.
Forms for the use of chainsaws
With full safe to say that today the market is dominated by chain saws medium and light universal models or semi-residential class.This is completely understandable, because demand among non-professionals, such as truckers, repeatedly increased.
On the first and foremost important to them reasonable price, service and ease of operation.The market offers equipment for every budget and taste, and sometimes less powerful saws are somehow much more expensive, and failure Husqvarna chainsaws are also sometimes found.Chainsaws for applications are divided into the following types.
Gross Gross - are tools that are designed for felling and bucking.This is the most difficult and powerful chainsaw.As a rule, they are equipped with circuits with high performance tires and great length.
One of the distinguishing features of modern engines is to use a saw with great traction and a minimum value of the ratio of weight to capacity.In addition, there are saws that are equipped with a rotary tire and long handles.This greatly simplifies the felling gashes in difficult conditions, and failure stihl chainsaw can be quickly corrected.Naturally, everything harvester blade referred to professional technicians.
Chainsaws universal - is the most famous form of chainsaws.They can be domestic and professional, semi-professional and even (this is determined by the resource).Loggers, for example, use it for their pruning and gardening workers and public utilities with foresters cut apart the rubble and dry trees.
Summer residents and rural residents because they can take care of the garden and cut firewood.Builders are also very actively using this type of saw.Also, they prefer to rescuers, road builders and others.With their help, even cut wood and ice sculptures.
compact (one-handed).Their second name - is a chainsaw, which are intended for the care of the crowns of the trees, which completely characterizes their main purpose.With careful removal of already damaged trees and kronirovaniye need to work not as usual on the ground and hanging on the rope or on the stairs.
In this position, the saw has to keep just one hand, and the second you need to keep yourself.That's why, in contrast to the usual arrangement, one-handed chainsaws handle for the right hand is not behind, as always, and the top blade so that the center of gravity is located under the handle.
Chainsaw "one-handed" - a record holders by weight and compactness.Besides landscapers they still interested hunters, fishermen and tourists.These saws are called professional, while they differ in a very high price, which is typical of professional equipment.
What are the details of maintenance are usually the most important?First - this is, of course, sharpening the chain.This obvious effect dramatically affects the state of the entire instrument absolutely.The chain may be confused, then no work will not be done: the tool will only "burn", but did not saw.
The problem is only that the chain saws can be very simple blunt.Therefore, the professional repair faulty chainsaws friendship without very high-quality sharpening is not correct.Such action must necessarily perform only expert.In another case, equally, not all teeth can be sharpened and then saw exactly lose its effectiveness.Recovery tool is generally more expensive than originally preventive maintenance done correctly.
second - this chainsaw chain tension.And it is nothing strange in the fact that the circuit can be stretched: the chainsaw so often exploited, even very thick chain quickly weakened.Do not stretched chain can easily break.It should be understood that, in this case, human security can be threatened.
third - is the lubricant.Provided that the oil will be little, chainsaw will fail very quickly.Keep in mind that check the operation of the entire lubrication system is necessary after each run the tool.Determine the correct operation is very easy, you need to see if there is a drop of oil on the surface of the saw.If there is, it means that everything is in order and failure chainsaw oleo poppy appear.
chainsaw Chainsaws, as well as other tools, sometimes fail.Therefore, the repair chain saws can be done by hand, too.How to repair the chainsaw with internal combustion engine?What are the possible faults chainsaw?It will not start or start, and then stalls.It may be that she does not work full power.The easiest failure when the chain breaks.Fix it can be very fast, just replace the circuit.There are faults carburetors chainsaws that can be repaired by yourself.
Checking the fuel mixture
begin repairs needed to check fuel level.It is not necessary to save.It should be understood that the cost of all repairs cylinder-piston cost about 2/3 the cost of a broken tool.It's probably a weighty argument to the fuel additive to buy some well-known brand with a good reputation.The proportions must be observed by those who are listed on the packaging of gasoline-powered operation.
fuel mixture should be made at the rate to two weeks to develop it.Further, the domestic gasoline begins to lose octane properties, and then begin with the launch of torment chainsaw.The mixture, which stagnant best discarded.It should only be fresh, so you do not have to repair the fault chainsaw husqvarna.
If the fuel mixture is all right, you need to look at the trigger.If it is also doing well, you should check the spark plug.To do this, unscrew the spark plug and look at it.It should have a clearance of 0.5 mm, which is necessary for the chainsaw to operate normally.
sure to pay attention, some spark - dry or not.If no signs of fuel, hence the reason for failure is in the carburetor.He could have something to hide.In this case, it is imperative to start to withdraw, and then cleaned.
If a new plug is installed, the carburetor cleaned, but the chainsaw still does not start, then it is better to look cylinder-piston group.Simply put, it is making a chainsaw work.The goal is to get inside the cylinder, which piston is located.If he has a specific chips or burrs, it definitely needs to change.Once the cylinder can be given under the repair size or bore.
Still worth checking the condition of the piston rings.They need to encircle the piston is very tight.To do this, insert the plunger into the barrel and at the top of its shake.If it is loose, then maybe he just demolished, and will not give a good compression.After analyzing the appearance of the piston can tell a lot about why the engine failed.
Lack of lubrication
Jamming may occur due to the fact that the engine overheated while working on a lean, but also at the wrong ratio of oil and gasoline in the fuel mix, and even if the wrong type of oil is used, or even its absence.
There are times when the heating is so great that the material of the piston becomes pliable.It is torn off near the piston skirt, and then adheres to the whole surface of the cylinder.Moreover, because of the very rapid expansion of the piston, the inlet side also gets a teaser.
Generally the piston ring is not damaged, and walks freely in the ring groove.Finding the piston chainsaw medium or deep teaser, it is imperative to carry out a set of actions:
- Use properly prepared fuel mixture;
- Use fresh fuel with a high octane number;
- replace damaged parts;
- Seals and gaskets to replace the current;
- Clean the air intake and cooling fins;
- Clean spark arrester screen.
Excess engine speed
Still, there is one common reason for failure chainsaw partner and bearing damage stopper, piston rings piston pin - it is a very large engine speed.
destruction of all the piston rings often occurs when the engine speed exceeds the allowable.When the temperature rises when driving a jam occurs in a groove of the piston ring, which does not allow the piston ring to withdraw completely into the groove.As a result, advocates sharp edge of the ring, which is beginning to cling to all the irregularities and clamped in the cylinder, thus bringing it to the normal damage.
Very high engine speed will lead to tapping on the pin end of the piston ring as it moves along the groove.When the knock becomes intense, it could knock out the piston pin, while causing tangible damage and the piston and cylinder.
soot and dirt
of the damage due to excess accumulation of soot on some of the symptoms resemble those of damage when inadequate lubrication.Soot accumulates in the combustion chamber in the cylinder and the piston at the top.
Its skirt has a slightly darker hue by passing over the hot gases that are formed during combustion, and make their way under the piston ring itself.In this case, you must replace gasoline, and then adjust the carburetor chainsaw.
Absolutely any substance other than fuel and clean air that gets through the inlet to the engine, can easily cause damage to the piston, increased wear and malfunctioning chainsaw Urals.First we need to make sure that the right thing to do to install and no defects.In addition, with significant damage should be checked fastening parts of the carburettor and intake system.
problems starting the engine
How to start a cold engine immediately after purchase in a store or after storage, ranging from two days?When buying from a retailer GASOLINE consultant can tell in detail all the subtleties of the work and start-up and gasoline-powered tools, and even this still demonstrate in practice.
To start a cold engine, set the lever (otherwise it is called Switch) to the position called "flap closed".Next, you need to pump the mixture into the carburetor, if available fuel pump.Then pull the starter handle until the engine until resistance becomes noticeable, and vigorously pull amplitude taking his hand to the side.
After two or three such motions engine must first be got, and then stall.That may not happen, then it is necessary to translate the lever in position polugaza or just position and continue the institution in this mode the same motions.After all this usually start.
If you still did not work, and the saw does not start, you need to calm down and then catch your breath for a few minutes and try the same mode to run again.Some powered tools have a simple push button ignition, need to ensure that it was included.
