Hi guys!
Last year I received as a gift a Hitachi DS18DJL drill. I've used it a couple of times as a hobby and I really love everything about it. Recently I got it out of the case in the house to test fit some new bits I bought and I heard a weird sound coming from it when the HIGH gear is engaged. In the LOW gear it sounds just fine, but as soon as I change to HIGH gear it starts to make that sound. Can you guys help me figure out what that is? Is it normal? The sound kind of changes if I point it downnwards and if turned upwards doesn't sound at all. I tried to upload the video on youtube but it cut off the sound so I uploaded it on google drive.
Thanks!
