allowing the same slack at the drill toolbar pivots as the other
hoses. Use the rubber hose protectors and hose clamp
brackets which are already bolted to your drill to secure the
hoses in place. DO NOT alter the routing or amount of hose
slack of the existing hoses when you loosen the clamp
brackets to insert the marker hoses. Tie the marker hoses to
the opener lift hoses at the toolbar vertical and horizontal
pivots with cable ties (#16).
3. Bolt the sequence valve (#6) to the valve mount bracket (#8)
on the center of the center box frame with the 3/8" x 3/4" long
bolts (#7), and 3/8" lock washers (#14). Mount the sequence
valve (#6) so the side with four ports is up.
4. Connect the 272" long hose from the rod end of the left
marker cylinder to the port marked "C1" on top of the se-
quence valve. Connect the 252" long hose from the base
end of the left marker cylinder to the port marked "R1" on top
of the sequence valve. Connect the 272" long hose from the
rod end of the right marker cylinder to the port marked "C2"
on top of the sequence valve. Connect the 252" long hose
from the base end of the right marker cylinder to the port
marked "R2" on top of the sequence valve.
5. Route the 348" long hoses (#5) down the center of the
tongue tube and connect them to the adapters on the bot-
tom side of the sequence valve (#6). Make sure the hoses
do not interfere with the center box frame clutch assembly.
6. Bolt the selector valve (#10) to the valve mount bracket
(#17) on the tongue tube with the 3/8" x 3 1/4" long bolts
(#13), 3/8" lock washers (#14), and 3/8" hex nuts (#15). In-
stall the 1/2" FNPT adapters (#9) to the front and rear ports
of the selector valve (#10) and the 3/4" JIC elbows (#12) to
the cross ports. Assemble the 96" long 3/8" hoses (#11) to
the elbows (#12) on the selector valve.
7. Connect the 348" long hoses (#5) to the rear adapters on
the selector valve (#10). Connect the long hoses from the
fold hydraulic circuit to the front adapters on the selector
valve. Secure the four 1/4" hoses going into the selector
valve to the top of the tongue with the hydraulic hose guards
(#18), the hose clamp brackets (#19), the 5/16" x 2 1/2" bolts
(#21), and 5/16" lock washers (#20). The 5/16" bolts screw
into the nuts which are welded to the top of the tongue tube.
8. Tie the hoses down with plastic cable ties (#16) to prevent
pinching or kinking of hoses during the folding operation.
Tieing the hydraulic hoses to the marker mount tube as
shown in Figure 3 is the preferred way to assure that they
will flex properly and not get pinched by the marker first sec-
tion.
IMPORTANT! BEFORE FOLDING THE MARKER, BLEED ALL
THE AIR OUT OF THE HYDRAULIC SYSTEM.
9. Bleed the marker hydraulic system as described in the drill
OPERATOR’S MANUAL.
10. Set the marker raise and lower speeds as described in the
drill OPERATOR’S MANUAL.
Drill with Fertilizer Attachment
