A lightweight powerful chisel was used as a chisel on brick and superficially on concrete. The design of the D-type handle and its length result in more digging meters with one step up the ladder, you can easily dig a length of 1.5 meters, the tool along with the chisel is 1 m. The chuck is the sturdiest I have seen in MAKITA tools, it looks like SDS MAX but is SDS PLUS, which makes it very good for leveraging bricks, also due to its length. Maintenance only requires carbon brushes and grease in the chuck. The negative aspect of the tool is in the repair of the impact system; it is so complex that when we requested a repair, no service accepted it, only a replacement of the impact head at a cost of 250 euros. In the end, I opened it and understood the refusal of the repair, as it should have been simpler because the rotation system is missing; it required special tools for this head. Otherwise, it is perhaps the strongest in its weight class.

Eventually, I added the fifth star after trying to repair all three chisels; photos and videos will follow. The service I sent it to, which could not perform the maintenance, returned the hammer and piston tube cut in half from a blow, and now I understand why. They could not remove the internal safety; soon I will upload photos and videos showing how the solution and assembly are done
