I've had a leak at the control valves for some time now but recently it has accelerated.  I assume there are seals & maybe O rings that are replaceable.  Is there a factory manual available?  Does anybody have a copy?  An exploded diagram would be helpful. Are there any special tools required?  Does anybody know if the valves are a Kioti product?  I didn't immediately notice a name or model # on them.
