The difference between the 691045 and the 691085 is that the 85 model comes with a Walbro carburetor and an OREGON chain and blade, compared to the 45 model. This is mentioned for the main person to see, along with the following comment, so that future users can also see it.

As for the chainsaw, from the moment you tighten and hold it, you feel like you have a sturdy tool in your hands, with the highest quality plastics and metals they could put in it for the price.

It is satisfactory and well-made as a machine, especially when you remove the cover (it opens very easily) and see the air filter and the rest, not to mention the WALBRO carburetor!

As for the weight that everyone talks about, a chainsaw like this MUST have weight so that you can place it on a fallen trunk and it cuts on its own, without the user struggling or needing to sit on the machine to cut.

To start, I tested it on a small log without cutting, and then gradually moved on to some small and medium-sized logs that the chainsaw cut through like butter, without any effort. Soon, I will do the crash test and I will come back with more feedback.

***After the Crash test***
I can say that I was impressed by the power and the comfortable use, despite the weight of 7.5 kilograms.

I cut medium and large olives, large cypresses without any problem.

So far, the chainsaw is worth 101% of its price in every aspect.

The only thing I would suggest paying attention to is the correct tension of the chain and the adjustment of the guides, making sure they are as precise as possible, in order to have a comfortable cutting experience and low fuel consumption.

Also, a regular cleaning after each use with a brush or an air compressor (preferably) on the main chainsaw, the clutch-bell area, the blade, the chain, etc., will save you from many troubles.

There are many videos on YouTube that show simple ways to help you pay attention to how to perform basic or more advanced maintenance.

I bought it the day before yesterday. The model is as stated in the prospectus on the cover, it is the CS5600-4. On the second-to-last page, page 21, in the table of technical specifications, it says above that the code is 691045 and 691085, which means it is the same saw as another one further down on the site. I don't know what differences they have between them, from the photos it doesn't seem like one has a black blade and the other has a white Oregon blade, but both have the same guides and blade dimensions. The one I bought has a primer, fuel pump, and a gas bubble. The photos on the store's website should have been more numerous, as well as the details, and not lazy copies like I suspect they do, meaning if the original site doesn't mention the gas bubble, no one else does either, as everyone copies the original and the buyer can't compare between the models. I say this generally for all brands. I also have another similar Chinese brand 50cc chainsaw, very powerful, many years old, without a gas bubble. It used to start easily after 16 pulls of the rope, but now I struggle for hours to get it started. I have to remove the spark plug and pour a little clean gasoline into the cylinder. That's why I bought this one, for the gas bubble and the Walbro carburetor, which is highly recommended, although I suspect it's not American but Chinese, the Walbro-type carburetor. But at such a low price, I think it's unlikely that it could be a genuine American one. The Craftsman's bell is the same as the old Chinese one I bought from a friend who found it heavy, but it also takes a chain sprocket rail at a low cost if it breaks. Mine broke and the chain kept coming off, so I put on a sprocket rail for the chain after many years and many difficulties. I use it for cutting thick, hard olive and cypress trunks when they break from the wind and fall in the olive grove, so I don't strain and destroy another smaller chainsaw that I have of a good brand. From my long-term non-professional experience, I generally say that it is a saw for amateur use, for cutting thick trunks, not to work at full power for hours without turning off. It is heavy, it vibrates during cutting, and generally requires strong hands. For example, if someone is of a certain age and can't handle the weight for hours because they suffer from, for example, weak hands, etc., they should get a smaller one of the same brand. Its chain is razor-sharp, be careful of injuries when touching it. I would prefer Kraft to release it in a version with larger cutting system dimensions, i.e. a longer blade. Thicker cutting chain, longer blade, and rail sprocket for the chain on the chainsaw straight from the factory, like it comes out, the chain saw with a chain rail from the factory. The prospectus is greatly improved compared to previous ones, it is only in Greek with very informative and detailed sketches-images, but I would prefer it to have slightly larger A4 page dimensions and more technical details regarding the dimensions and sizes of the spare parts so that the mechanics do not have to order and try various ones until they find the right one and then return it and say send me the larger or smaller one, delaying the repair. I have experienced this, for example, with chainsaws, chains, and blades, they should directly put the size mentioned in the prospectus. I easily cut small olive tree branches up to 15 centimeters thick after letting it warm up at idle for over 3 minutes and turning it off every ten minutes and waiting for it to cool down for about twenty to thirty minutes before starting it again and cutting with a relaxed grip, not full throttle, at most 3/4 of the throttle for one or two tanks for bedding. On the second day, cutting in the same relaxed style to bed it in, it had irregularities, it wouldn't hold idle, it would turn off, it would bog down and turn off during acceleration, and to get it running again, it required multiple pulls and choke even when warm, and despite adjusting the idle screw, it still wouldn't hold idle and would either turn off or rev too high. The prospectus states that this is normal and that the carburetor needs a slight adjustment after initial operation, so I took it back to where I bought it and an authorized technician immediately came, adjusted the carburetor in 5 seconds, and I left right away, and now it works like a Swiss watch, it starts right up, only the distance wore me out, 60 kilometers round trip, but I combined it with other tasks like shopping, going for a walk, market research, etc., I couldn't do otherwise due to the warranty. Only the idle can be adjusted, which has a screw for the screwdriver. For other adjustments, the carburetor does not have simple screws for a regular screwdriver for the H and L adjustments, and it requires a special tube screwdriver for authorized technicians only, at least until the end of the one-year warranty, which is very appropriate, just like with expensive machines from good brands that require a special tube screwdriver. It seems that the Chinese are improving and at least they copy the right machines. Let me say, by the way, I heard on the radio that two large factories open in China every month. It is also said that the Chinese have set quality standards in their industries and that about 15,000 factories that cannot meet the quality standards will close. I believe that this will last me many years, just like the other Chinese one I have, which still works, even though I didn't take care of it, I used old oil, left gasoline in it for years, but I repeat, it is very powerful. I only want it for thick pieces or as a backup if my smaller chainsaw from a good brand breaks and is missing for repair so that I don't end up without a chainsaw. The box contains 2 spark plug wrenches, 1 Allen wrench, 1 screwdriver for the idle, a chainsaw file, a small mixing container. Pay attention to the mixing ratios, good mixing, a funnel with a mesh filter or a filter paper, and because the Chinese require a large oil-gasoline ratio in the fuel, it clogs up quickly due to the excessive oil in the fuel, especially after about 200 hours, the fuel filter inside the fuel tank gets clogged and cannot pump fuel, and it needs to be replaced or cleaned properly. Also, be careful with the new spark plugs, they have a threaded cap made of soft aluminum that loosens with temperature and does not make good contact, causing it to turn off. It won't start again, in general, any machine of any brand can be easily fixed, it can be changed by a mechanic with a spark plug pipe without the aluminum cap. Also, always use fresh fuel, smokeless oil, synthetic or semi-synthetic, leather gloves, ear protection, a protective face mask with a hard mesh, safety glasses, work boots with steel toe caps to prevent cut wood from falling on your toes and crushing them (my toes have been blackened from hitting wood many times), and definitely chaps (I have destroyed my good pants from my legs for years, they are black from the cuts from the chainsaw). And not excessive throttle and force, not only to avoid damage to the machine but also considering that when powerful chainsaws are strained and hit wood, they encounter nails, stones, hard metal, pink wood, they break the chains and either throw them high and far away as broken chains or small hot nails from the teeth of the chain fly at high speed and penetrate deeply into the body, for example, in the eyes, fingers, causing blindness, injury, or death. So be careful and never use a powerful chainsaw when you have consumed alcohol or when you are drowsy from medication, heavy meals, fatigue, etc. I personally drink a bucket of coffee before using the chainsaw to stay alert. It requires great caution and readiness to use any chainsaw so that you don't lose fingers, tendons, hands, and feet, so you don't see people with severed limbs, bandaged with gauze. I have seen it all, that's why I'm telling you, and if someone can't handle a powerful chainsaw, the world won't end, there is a solution, for example, they can give it to someone else who can handle it and pay them for the job
