    Finally got enough snowfall to put the new plow
    through it's paces and what do you know it laid
    down and needs some tending to..specifically the
    blade won't hold in the raised position...It raises--
    ---pauses--- then drops hard.

    A quick peruse of the online manual shows
    that a stuck solenoid valve S1 to be a likely cause.
    Or internal check valve? Is the internal check
    valve behind S1?

    How's Fishers warranty??

    Anyone care to share the procedure on getting this fixed?

    Is this a part(s) worth keeping on hand or is this uncommon?

    Got it fixed--pulled solenoid S1, couldn't see anything ovbiously wrong. Squirted
    some kroil into the end, worked the plunger with brass welding rod. Reinstalled
    and it now works.. Good to know... Shoprat...
