Complete Manual Information
Yamaha CS340 Series Service Manual - 1989 Edition
This technical publication provides factory-spec maintenance and repair protocols for the 1989 Yamaha Ovation series. A critical system requirement identified for operational longevity is the mandatory air bleeding of the oil pump and delivery lines whenever the oil tank is depleted or the chassis is overturned, preventing immediate engine seizure.
