DUAL FLAT FOLD MARKER ASSEMBLY INSTRUCTIONS

Refer to Fig. 2 as reference for the following instructions:

Attach the hydraulic fittings (#12) to the marker cylinder.

Install the selector/sequence valve to the selector valve mount, located on the T-Frame, using 3/

8" bolts (#2), flat washers (#3), lock washers (#4), and hex nuts (#5).

Route hoses (#6) from the selector/sequence valve down the transport frame tube. Check hose

routing for pinching and kinking of hoses and securely attach with plastic cable ties (#7).

Attach hoses to cylinder ports. Be certain to double check for correct port location back to the

sequence valve.

Detach existing tractor hoses, (#8) and (#9), from fold cylinders. Attach 66" hose (#10), 42" hose

(#11), and tractor hoses, (#8) and (#9), to the selector/sequence valve (#1) and fold cylinders. Assem-
ble remaining hoses as indicated.

Cycle attached marker to transport position with the cylinder closed. Sequence valve should shift

and activate the other cylinder. Refer to page

1-7 for proper cycle sequence.

When ready to fold wing boxes for transporting, position the handle on the selector/sequence valve

towards the port marked "G". Hydraulic oil is now diverted to the fold cylinders.
