pins and roll pins provided. Position the cylinders so

the hydraulic ports point forward.

2. Using a 1-1/4 x 6-1/8 fold pin, flat washers, and 5/16

the front center gang using 1/2-13 x 3-1/2 hex head

cap screws and hex lock nuts.

5. On 33’ models, attach the manifold to the rear

manifold brackets on the implement using 1/2-13 x

3-1/2 hex head cap screws and hex lock nuts. Install

adapters in the front ports of this manifold.

6. Install lift system hoses per Figures 3-10, 3-12, 3-14,

and 3-16. Wrap lift system hoses with blue hose

wrap.

7. Attach hose clamp brackets to the scraper bar (See

Figure 3-20.) On 33' units, attach a hose clamp in

the ninth hole from the center of the machine on each

side of the front gangs. Secure hoses to the brackets

with hose clamps, 3/8-16 x 1-3/4 hex head cap

screws, and hex lock nuts.

8. Install fold system hoses per Figures 3-11, 3-13,

3-15, 3-17, and 3-18. Wrap fold system hoses with

leveler hoses with black hose wrap.

10. Install plugs from lift cylinders in any remaining open

manifold, valve, or cylinder ports.

Restrictors are installed to prevent uncontrolled

dropping of wings. Removal of these restrictors,

or improper installation can result in serious

damage to the implement.
