Owner of two machines with this code (6 crafts in total). One year later, one still works (45 acres of olives, 10 vineyards) the other one burned in May.
Negatives. The fuel cap does not seal properly and gasoline spills on both when working. The carburetor is misadjusted and works clogged with 50% power, consuming terrifying amounts of fuel, 4 l/h liters per hour and more.
The solution is an extra wheel on the cap and adjusting the screw on the carburetor, it needs tightening downwards. Another machine afterwards...

Positives! (adjusted) lots of power! you work at 2/5 throttle.
Consumption is one fill per acre, depending on the grass/cotton.
The plastics are fine.

Gloves, glasses, masks, pants, boots, ear protectors definitely! there is no chance of not getting hurt.

And remember, Unimac never recognizes warranty. It's always the fuel's fault.

Purchased about 2 months ago. It has cut around 6-7 acres of grass up to about 1 meter (10-15 hours of operation). Very powerful, with a good trimmer it mows well.
3 observations:
1) As stated on the fuel tank, it works with 25:1 for the first 20 hours. Currently, the exhaust spits out a lot of mixture, but I assume it's from the excess oil. When it goes to 40:1, I think things will be better. I use Nakayama LB1050 mixing oil.
2) The spark plug broke in the first 4-5 hours. I replaced it and it continued.
3) The clip from the automatic head broke, but no malfunction has been observed.
Time will tell how long it will last.
For the money, it is highly recommended! If it holds up, I will give it 5 stars!
P.S: If anyone has any other mixing oil to suggest for this specific model (62cc), I would appreciate it.

I got it for settlement in the mountains, wholesale 1 acre in total, completely clueless about the subject! After a friend who knows helped me at the beginning, then... goodbye!! The tool kills, you don't even feel it! It easily cut grass up to 1 meter high, got stuck in very thick ones with the string, but after 2-3-4 passes it cut them too. The automatic string is a great convenience, I wound up 2-3 meters and whenever needed it came out by itself!! Highly recommended, I would give 2 workdays for that money, while now I have a beast!

Update, after about a year I still remain very satisfied, it is a very powerful and tireless machine, its consumption has improved a bit. You get it with closed eyes! Excellent convenience that splits in 2 for transport!

It did not last long. I had a fifty but it broke and I bought the sixty. It's a shame they make them with cheap materials now, the Chinese. From the beginning, when I was emptying the fuel, it was leaking from the plastic tank and the plastic softened especially at the point where the filter was rubbing against it. It didn't puncture, but it was ready to. I wrapped the plastic tank with adhesive tape to reinforce it. Then the handle broke and the central iron of the handle came off from the plastic base because it was glued due to the high temperature caused by intense use in hot weather. The first thing one should do is remove the handle and take it to a repair shop to carefully attach a sturdy screw in the center from the outside to hold the central iron in place, which is wrapped with springs. And if another handle breaks from a different model, the screws fit handles of other brands. I temporarily used a handle from an Oleo-Mac 746, the iron one, because it developed high temperatures there. I struggled with long screws and nuts, unfortunately the high temperature melted the inner plastic wheel that touches the skin and the rope, and I came up with another solution. I removed the pins and screwed a metal tube onto the axle of the crankshaft with electrically welded screws on one side and a cut on the other, and I put it in front with a pin. Unfortunately, this system did not work, it would move forward but then loosen over time due to the turns and I would find it in the field. In fact, as soon as it started moving forward, I would put a stick to immediately tighten it before losing the tube. I tightened the axis of the crankshaft where the pins screw in with cork screws, but it broke and I put another tube after I solved everything. I removed the flywheel and put the crankshaft from the broken fifty, it worked for a while but it also broke. The tube of the rope broke again, I analyzed it and glued the flywheel of the broken fifty to the tube with a tight fabric tape or a bandage so that it doesn't rotate on the tube. It would often turn off lately, but it would start again immediately as if it was clogged by something. I found out that a metal spark arrester accessory had fallen into the exhaust and was blocking it, causing it to turn off and smoke a lot. It also needed a lot of oil in the gasoline, but I didn't put oil of good quality because I was working for six to eight hours a day, almost all summer, cutting grass and cleaning grass. When I returned home, I smelled strong burnt gas, not only on my clothes but also on my hair and skin. I had a strong cough and difficulty breathing, as if I had smoked packs of unfiltered cigarettes. My eyes were black and I had a strong cough, as if I had smoked packs of unfiltered cigarettes. My eyes were black and I had a strong cough, as if I had smoked packs of unfiltered cigarettes. I found out that the aluminum parts of the engine melted, and the handle also broke. I made makeshift solutions with wooden sticks and screws, it's a shame because it's a very powerful machine, but with slightly better materials it would be worth more. Now I only have the stick and the belt, the plastic protective cover, I can put it on another engine as a second backup machine. The trimmer head is unacceptable, the head comes off the screw and goes back in, but then comes off again, you lose it when cutting grass, and the head and the spring are lost. I tried to weld the screw inside the head after heating it with a blowtorch, but it was welded crooked and had strong vibrations, it became unusable, I threw it in the recycling bin along with the plastic trimmer head that was inside the machine's packaging. I used a trimmer head with a screw from Oleo-Mac now, they now produce it with a threaded plastic screw that is securely fastened (in this case, you need an adapter with a screw for the machine's head). I won't make the same mistakes again, makeshift solutions. Keep in mind that I used it almost professionally for five to six hours a day, cutting grass and cleaning grass, iron grass, thistle, low myrtle, and shrubs. These machines were made for lawn grass that they have in Asia and Northern Europe

I bought it after the store's recommendation, as the older model was sold out. They told me it was more powerful and had a new engine. Well, I used it for 2 days and it burned 5 liters of unleaded gasoline with a 40/1 oil ratio. I bought the foldable one because it's convenient for moving around with the family to the beach. Easy assembly after 5 liters and a few hours of work. I have to say: It is indeed very powerful, but not so economical (63cc). It easily handles grass up to half a meter with a universal head with 4 3.5mm outputs. It requires some work for thicker weeds and sea reeds of 2 meters, but without a blade, of course. Considering what I've heard about the Manisian blades losing their balance, I don't think I'll risk installing it. Although with a good blade, I believe it wouldn't take me much longer for the thicker weeds and reeds. Overall, it's worth its money (it's Chinese), now we'll see if it lasts. Get it with your eyes closed. It would cost you 2 days' worth of work to have someone else cut the grass as much as the machine does.
