The raise switch should be closed (continuity) when
the center deck lift/lower lever is in the neutral position.
As the lift/lower lever is slowly pulled back, the raise
switch should open (no continuity) after thelever has re-
moved all free play (with no spool movement in lift/lower
control valve) but before the deck is lifted.

The lower switch should be open (no continuity)
when the center deck lift/lower lever is in the neutral
position. As the lift/lower lever is slowly pushed forward,
the lower switch should close (continuity) before the le-
ver reaches full forward travel.

At only 700mm wide the Mini Dumper is even at home on tight access
sites. No need to grunt, groan, and force the
