Big Machine – Cold Start After 3 Years + Test Drive

In this video, we attempt to start the massive KN-251 loader, a heavy-duty machine that hasn't been used for approximately 2–3 years. We go through the entire process: checking the oil, connecting the batteries, and fueling the engine before making several attempts to bring this giant back to life. Watch the video to see if we manage to revive this powerful machine and hear its engine roar once again! 00:00 Intro 00:18 Exterior 00:55 Interior 01:30 Fuel 01:45 Battery 01:55 Engine 03:45 Battery 04:40 Filter 06:11 Deaeration of the pump 07:15 Filter cleaning 08:50 Starting 11:30 Test Drive KN-251 specs: Engine: V6 diesel Power: 240 HP Bucket capacity: 3.5 m³ Production period: 1970s–1980s If you enjoy watching old heavy machinery being revived, don't forget to like, comment, and subscribe for more epic machine starts!
