Implement Fold
The fold/unfold (and weight transfer) functions are on a
hydraulic circuit that is shared with the hydraulic fan on
the air cart. The fan must be disabled during fold and
unfold, but is not disabled for weight transfer.
Overhead Crushing Hazard:
To prevent serious injury or death:
▲ Always use transport locks when implement is folded.
▲ Fold implement only if fold hydraulics are bled free of air
and fully charged with hydraulic oil.
▲ Stay away from frame sections when they are being raised
or lowered or are in the raised position.
▲ Keep away and keep others away when folding or unfolding
implement.
Electrocution Hazard:
To prevent serious injury or death from electric shock, keep
clear of overhead power lines when transporting, folding,
unfolding or operating all air drill components. Machine is not
grounded. At higher voltages, electrocution can occur without
direct contact.
