Hi, Ray benson.
I have a 2017 one month old cs-620p. I asked my dealer for the service manual on a new thumb drive and he gave me a 10 page Service data thing. Also I have the BP770, cs-355T, and a new PAS2620 unit with the Bed edger, sweet tool big time saver. I made the change up from Stihl, only a old FS80 left. Any way he could not find a cs-355t and gave me a cs271 manual instead and the BP770 and PAS2620 were just carburetor adjustment for north America? This change up started with the cs-355t and man what a nice saw, then I went for the cs-620p over my older Stihl 36 and 360.
Can you help me out?
Thank you Ohio
