Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.
Excellent service from Owner-Manuals.com, good prices and quick turn around. The supplied PDF was good enough quality to be enlarged sufficiently to read component values.
