Chainsaw “Makita Dcs4610”. Question – Answer.

Question:

There is a Makita 4610-40 chainsaw. Lately, it has sometimes begun to stall, that is, it starts up normally, but releases the gas and it stalls. Stalls because the starting valve, which must be pressed before starting, after it is wound up, does not crawl back (as if sticking there). I thought that because of the dirt, but he unscrewed the case, cleaned it, rubbed it, but it did not help. When I removed the casing, I noticed that on the nut, on which the button goes, there is a small hole. So the question is. can I pour in some oil to lubricate it, I’m afraid, as it were, not to spoil it at all.

Answer:

The valve that you called the start valve is called a decompression valve. If this is it, then it is not necessary to press it before launch. over, I have repeatedly mentioned that these valves are often source of problems (possibly because they are made by the Germans for European, and not Russian, fuel). So forget about it and start your saw as if it is not at all. The saw can stall at idle for many reasons, which are divided into faults and lack of maintenance. It is difficult to rectify faults, although some do change the piston, completely disassemble, assemble their saws, but this is rather the exception. An unsuccessful repair usually leads to a severe malfunction of the piston badass type. Therefore, only maintenance procedures for the Makita chainsaw remain. And there are only two of them. The first is washing the air filter in warm soapy water and replacing the fuel filter on the intake manifold. And the second. the adjustment of the carburetor. But this procedure is risky and justified very infrequently. Just from the factory, the saw is already adjusted and almost does not require further adjustment. Only if you slightly adjust the idle speed and all. To summarize, rinse, and replace all filters. And most likely your saw will work again as it should.

Question:

Exactly a week ago, at the dacha, Makits dcs4610 started without problems, did not start a week later, dilute the oil according to the ratio, pour the oil for the chain, clean it all the time so that no matter what happens. I drink in a sparing mode, especially not so much that I saw. I took off the candle to check it was flooded accordingly, I dried it, I don’t know what kind of spark it should be but it’s barely perceptible (compared to its friendship there isn’t anyway along the way), but it’s hardly noticeable, it’s not useful anymore, it doesn’t even catch it. What could be? Still a candle?

Answer:

What kind of oil and in what proportions (by eye or using a measuring container) diluted with gasoline. How much was the fuel mixture stored? Tried to put another candle? Remove the muffler and look at the cylinder and the piston ring. If there are scuffs and scrapes or “ring lay down.” That compression in the cylinder will be too low, and the candle will be flooded. If everything is standard, carry-in service, possible reasons can be listed for a long time, and without tools and knowledge of the device can not be repaired.

Question:

Chainsaw Makita DCS 4610-35. When operating, oil for the chain is trickled, and when the engine is off, it also flows. Is it possible to regulate the flow of oil to the chain?

Answer:

On this model of chain saw, the oil pump is not adjustable.

Question:

In operation of Makits DCS 4610 chainsaw, the feeling that power dropped, removed the air filter, did not help, the candle was black, wet, but at idle it works steadily, I fill the oil with gasoline with a syringe. The silencer seemed to be shooting clean, twisted it in his hands, what was there to watch? How to determine what is jammed muffler? Is it possible to adjust the carburetor and how to do it without damage to the technology?

Answer:

Maybe the gasoline is terrible (if the car usually goes on gas, it does not mean that the saw on it will work typically). Change the gas. What is sawing, the diameter of the log? Chainsaw Makita does not “like” weak loads, and I realized this when I saw logs 30-40 cm in diameter for firewood. Under light loads, the candle will be black in soot. If the change of fuel does not help, then let them carry out carburetor adjustment in the service.

Answer:

Using the universal wrench supplied with the chain saw, follow these steps. Place the chain saw on a stable surface and follow these steps to establish the tire and saw chain. Release the chain brake by pulling the hand guard in the direction of the arrow. Unscrew the lock nuts. Pull up the sprocket guard. Return the chain tension to the left (counterclockwise) so that the tensioner pivot of the chain is below the threaded pin. Install the tire. Ensure that the tensioner pivot of the chain fits into the hole in the tire. Lift the chain over the sprocket. Tension the chain around the final sprocket tire of the Makit chainsaw in the direction of the arrow. Replace the sprocket guard. Raise the saw chain above the chain stop. Tighten the lock nuts firmly by hand.

Question:

The problem with the launch was found on the Makit 4610 chainsaw. The starter is tough to turn the saw, and there are not enough turns to start, then there, pull, but it is very hard going. Turned the candle, then scrolled perfectly. Wrapped the candle, the saw started up. Worked, drowned. again, do not scroll. It seems that I am not scrolling through an engine of 45 cubes, but at least a 1.5-liter car. I’ll take it to the service, and that’s the German assembly. Is her clutch wedged? Did nobody face such a malfunction?

Answer:

No grip. Constructive such that does not affect. Perhaps the oil in the gasoline poured.
