I have the oleo mac s18 for many years now. Reliable, lightweight at 4 kilograms. I use it on weekends during the summer and I take it in the car because I store it in a source and if I leave it, I will lose it. However, there are no more available and no spare parts.

I have it for years. A star. I watered even a field with a river for six to seven hours straight in August with scorching heat. It requires attention if the water runs out in the well, either the engine gets frustrated and revs up to the maximum, or if it remains overheated for even a short time, it may get damaged. The pump blades were damaged by gravel from the well, and it pumped less water than it should, so I took it to the repair shop. Luckily, there is a replacement and it will be fixed. It is a two-stroke engine and does not have an oil tank. Four-stroke engines with oil tanks have the following issue. If they pump out all the water and work without water, and they do not have an automatic gas restrictor to automatically reduce the RPM when there is a lack of water, they rev up to the maximum due to the lack of water load, and the flange between the pump and the engine gets damaged, allowing water to enter the oil in the tank, turning the oil milky, and then it needs to be repaired by a mechanic if it is cost-effective. That's why four-stroke engines should never work without water, not even for a minute. They should either pump from a river or from a deep well that does not run dry, or there should always be someone next to the pump to turn it off before the water runs out. A friend of mine told me that someone can adapt a float switch from a submersible electric pump to an engine, so that it automatically turns off when there is a lack
