9. Mount the support arm saddle (34) to the support arm (27)
with 1/2-by-2-by-3-inch u-bolts (30), lock washers (28) and
hex nuts (29). The support saddle should be centered under
the marker chain and the square tube of the second section
(2) when folded to prevent wear. The support arm should
support the second section so it is parallel with the seed-box
lid. Adjustment can be made by loosening the u-bolts that
clamp the marker carrier and slide marker carrier up or
down to parallel marker with drill box lid.
10. Fold the marker to transport position. With the marker chain
(15) in the slot of the support arm saddle (34), take up the
slack in the marker chain by threading 3/8-by-2 1/2-inch hex
bolt (12) out against the chain bar weldment (13), lock this
stop bolt in position with the two hex nuts (7).

Refer to Figure 2.
1. Attach fittings (2 and 7) to cylinder ports. Attach the needle
valve (3) and hoses to the cylinder fittings. Route hoses
down to the drill frame and along the back side of the drill
frame tubes to the center of the drill. Route hoses to the ser-
vice tees (6) for the slide cylinder. Install service tee (6) at
tractor hose connection and at the slide cylinder connection
as shown. Route hoses and secure with plastic tie straps to
prevent kinking and pinching during folding operations.
2. Bleed the air out of the hydraulic system. Refer to Bleeding
Marker Hydraulics, page 5.
3. Adjust the speed of the marker with the needle valve to a
slow setting. Fold the marker up and down a few times and
recheck for pinching and kinking of hoses. Reset folding
speed with the needle valve to a safe speed.
