4. Once the cylinders are connected, raise the unit com-
pletly. If the transport locks
are in place on cylinders
, remove them at this time.

Wing Fold
Refer to Figure 9
6. If wing stop pins are installed remove pins from wing
stop clevis .
7. Install pin in storage tube on wing stop.
Refer to Figure 10
Note: The wing locking valve is located on the center brace
bar close to the depth control valve (Models 1800-
3000) or on the bypass/down pressure valve (Models
3500-4000) to prevent wing movement during trans-
port and maintenance. The valve is shown with the
handle
in the open position. To close the locking
valve , turn handle 90 degrees, to keep wings from
un-folding.
8. Once the transport locks, wing stop pins are removed
and wing fold valve is in the open position (as shown),
unfold the wings (if folding unit).
Note: Make sure no one is under the wings during the un-
folding process. Watch for leaks and make sure hoses
do not get pinched during the initial unfolding process.
9. Once the machine is unfolded, raise and lower the
machine several times to purge air from the lift system.
Again, watch for any leaks and tighten if necessary.
