Constructive components of the chainsaw All the chainsaws are similar to their own structure, for no reason through the fact that they are produced in euro (ECHO, Stihl, Husqvarna) or Russian (Cedar, Ural). Inside the body are the main elements - fuel tank and engine, and outside the starter, handle, saw chain (frame) with the chain. The sharp jerk of the cable leads the engine, and the one - the saw road.
For the beginning we suggest that you learn with the video clips in which it is shown, like the chainsaw is arranged and like it works:
Stop working in the cut;
Starts up, but soon stops;
It stops starting;
Loses its power;
Most of the problems are caused either by interruptions in the motor's operation (fuel order, exhaust system, ignition, cylinder-piston fraction) or with defects in other systems and knots (clutch, obstacle chain, frame, order of lubrication). We look at the more common breakdowns and techniques for their elimination. The correct chain saw is starting with the 1st spurt and does not crash the saw
Ignition system test
1st, which must perform a breakdown of the chainsaw, - look at the spark plug, unplugging the wire and carefully twisting it with a special key. Components of the chainsaw ignition system: 1 - flywheel with magnets, 2 - ignition module, 3 - candle, 4 - high voltage wire
The spark plug is turned out to check its condition
Dry. Most likely, a fuel mash does not get into the cylinder. The occupation is not in the ignition system, hence the candle is turned back.
The fuel is splashed splendidly. The root cause of the excess fuel consistence is either in violation of the start-up rules, or in the incorrect adjustment of the carburetor. The candle is painstakingly wiped, the fuel supply is cut off and the starter is turned on - in order to remove excess fuel and to ventilate the combustion chamber. Then the candle is placed in the room and the construction is restarted.
Covered with black carbon. This may indicate the use of a bad oil, incorrectly adjusted carburetor, or an erroneously calculated ratio of gasoline and oil. The candle should be washed, there is a sharp object (an awl or needle) through the deposit, wipe the electrodes with a skin and place it for the room.
Checking the candle, should pay respect for the gap between the electrodes: the usual is considered 0.5 before 0.65 mm. A crushed or worn gasket must be changed. A huge number of dark carbon deposits for a spark plug says about engine malfunctions
For the sake of complete conviction, a spark must be checked. For this purpose, the ignition cable is put on the candle, the plunger nut and the cylinder are plugged, the starter is turned on and stares because of the spark. If it is missing - the candle needs to be changed. If the new candle also does not produce a spark - a question in the high-voltage wire or in the connection with the plug.
Fuel system correction
Pollution of the fuel filter. Remove the fuel hose and check that fuel is flowing. If the stream is weak, you probably need to clean the filter. It is taken out through the fuel filler hole and cleaned, in case of heavy pollution replace it with a new one. As a prevention, it is advised to do a fuel filter change once in three months.
Clogging the breather (holes in the fuel tank cap). Inspect also by detaching the hose, in case of blockage, clean with a needle.
No or missing fuel. The circumstances of the malfunction may exist fairly. The first reason is the clogging of the air filter. The atmosphere ceases to be made into a carburettor in an appropriate amount, due to this, because of the extremely enriched fuel consistency, the motor's business is disrupted. The dirty filter is neatly removed, cleaned and washed in water, then dried and installed for storage.
Again, one root cause is the incorrect adjustment of the carburetor. Adjustment is done with 3 screws. Timely remuneration of the fuel filter ensures a full fuel supply
The fuel hose and the air damper drive must be close to the nozzles
The throttle linkage of the throttle actuator is forced to be for its own place.
In the time of work, an annotation should be used, if it is allowed to perform just the worst. Composition: tech/regulirovka-karbyuratora-benzopily.html#ym_playback=linkmap&ym_cid=22632388"> Adjusting the chainsaw carburetor: technical aspects
The final root cause - a violation of the integrity of the membrane or the clogging of the carburetor channel . In order to fix the carburetor without the help of others, is to meet with all the details
without a break frequently there must be spotless, clean, dry and serviceable.
If the engine for small revolutions works fine, but for huge ones it begins to stall, the original cause can be covered in the spark arrester of the muffler, clogged with combustion products.
Procedure:
remove the muffler
buy (eat and non-collapsible models);
eat through the nagara using detergents
drink a hairdryer
set for
Dry cleaning is unacceptable, because carbon deposits contain carcinogens, which are dangerous for health reasons. Then removing the muffler exhaust hole is locked with an unblocked rag. there was a clogging of the silencer, should be taken care of due to the composition of the fuel consistency. The amount of oil should not defeat the norms recommended by the manufacturer. A bad oil property also has a bad effect on the motor performance.
Criticism of the condition of the cylinder-piston group
Often the engine does not start or does not work at full strength due to low pressure in the cylinder. It can exist due to the wear of the piston or cylinder, the sinking of the piston rings, the wear of the bearings. Partly to see the good of the cylinder-piston group (GPG) is allowed, removing the muffler and looking into the opening hole.
A compressometer placed in a candle hole will help to perform the compression set in the engine - in accordance with the results of the measurement it is also possible to express the state of the GPG. A clear reason is obtained only after a complete disassembly of the mechanism. If for a piston to eat chips or scratches, it must be changed. The piston ring must be clean and free of carbon deposits and should appear for its own place. Wear of the piston and crank mechanism is attributed to severe malfunctions
According to the results of compression measurement, it is permissible to discuss the state of the parts of the TsPG
Fixing the chain lubrication system
Let's look at the three main faults:
Leaking oil. It should be checked whether the tubes are tightly connected to the pump fittings and whether they are cracked. Problem tubes are sealed with a sealant or changed.
Missing oil supply. Most likely, the lubricant supply channels are clogged.
The appearance of cracks for the body of the oil pump. The remuneration of the detail is needed.
This is how the lubrication system is diagnosed:
Регулировка тормоза цепи
Препятствие цепи нередко не срабатывает из-за засорения смазкой либо опилками тормозной ленты и места около крышкой. Следует есть безвыездно части через засоров. Вероятно, лента простой износилась, тут ее должен поменять.Дело тормоза цепи восстанавливается с помощью механической очисткиНекие части бензопилы изнашиваются резвее, чем другие. К ним относятся ведущая звездочка, рама, гора, антивибрационные элементы. Ради резвой подмены запчасти лучше завсегда владеть около рукою.Do not despise and sharpen the chain.
