DANGER
Make sure no one is in the area where the deck will be raised.
The cable could come loose or break and drop the wing
suddenly causing serious bodily injury or death.
!
DANGER
If a cylinder fitting was loosened to mechanically raise the
wing deck up, be sure to also lower the wing deck with the
mechanical winch. Do not use the cylinder to lower the deck.
It will have an excess amount of air and will drop the deck
suddently.and can cause serious bodily injury or death.
1. Pull cable hook with cable out past the gearbox.
2. Attach cable to wing deck by routing cable around the
wing gearbox base and clipping the hook back to the
cable or by hooking the cable to the wing deck side
panel. Make certain the cable is secured and will not
slip or come loose before raising the deck up.
3. Turn mechanical winch handle to raise deck. If
cylinder rod will not retract while raising the wing up,
loosen hydraulic fitting on the rod side of the cylinder
to allow intake of air while raising the wing.
4. Secure wing deck in the raised position with cylinder
transport lock. See
“Transport Locks” instructions
on page 30.
5. Retighten hydraulic fitting if loosened.
6. Lower wing deck as follows:
If hydraulic fitting was not loosened:
a. Unhook cable and reel cable up.
b. Connect hydraulic hose to a tractor and lower
wing deck with tractor control lever.
If hydraulic fitting was loosened:
a. Loosen hydraulic fitting at the cylinder to allow
intake air to escape while lowering the wing deck.
b. Remove transport lock and lower wing deck with
mechanical winch.
c. Retighten hydraulic fitting and connect all
hydraulic hoses to a tractor.
d. Purge hydraulic system of air. See “Purge
Hydraulic System” on page 21.
IMPORTANT: If wing driveline profile is bent or
twisted, disconnect that driveline from the wing
gearbox before folding the wing up. This will protect
both the wing and divider gearbox. Repair driveline
before putting cutter back into service.
