Folding and Unfolding
Fold and unfold implement on level ground. Be aware of
clearance required to fold implement. See “Specifica-
tions and Capacities” on page 55.
Electrocution hazard. To prevent serious injury or death from
electric shock, keep clear of overhead power lines when trans-
porting, folding, unfolding or operating all air implement com-
ponents. Machine is not grounded. At higher voltages,
electrocution can occur without direct contact.
Overhead crushing hazard. To prevent serious injury or death:
▲ Always use lock pins when implement is folded.
▲ Fold implement only if fold hydraulics are bled free of air
and fully charged with hydraulic oil. See “Bleeding
Hydraulics” on page 15.
▲ Keep away and keep others away when folding or unfolding
implement.
