During the time I first seen a Dolly and then bought our first two I figured they were the best thing that came along since sliced bread. After owning them for a couple days I then knew I was right. Ran those two for a couple months, bought another for my Bro, few months later the 4 th one for backup . Only needed backup once when the module failed in dads saw,dealer had the part on the shelf.Bars, chain and sparkplugs were all we needed in the first two years. Airfilters and the one module were the only parts we ever replaced on those saws for more than 4 years . My own saw started feeling tired so I put a set of rings in it and ran it for a few more months, then a new piston and rings perked it up once again. The other saws just piled up hours on them. They were covered in black softwood sap and looked like typical pulpwooders saws but they still ticked on. Then came the worst news we could hear from our dealer, Makita had taken over and the whole supply chain for the SD saws was in turmoil.
Still have those saws, John has the one I bought for backup. I have bought several more used ones since the the Makita takeover and now can find parts online easily. The 115`s have become one of my go to saws most of the time.
