OPERATION
Hydraulic Hook Up Continued
3. Connect the two hoses from the transport lift system to the tractor. The hydraulic hoses are provided with the
adapter attached. Use ¾-16” standard thread quick coupler tips such as CASE-IH part no. 1285718C or
DEERE part no. AR94522.
4. Extend cylinder slowly while watching to see that the rod ends do not hit any obstruction. Because these are
re-phasing cylinders, the left cylinder will extend first and then the right.
5. Hold hydraulic lever in extend position for 15 seconds after cylinders are fully extended to purge air from the
system.
6. Recheck tractors fluid level and refill if necessary.
7. Cycle cylinders back and forth a couple of times to see that they operate together. Hold the lever in the
extended position a few seconds after each cycle for additional air purging.
8. Retract the cylinders and reconnect rod-end pins and hairpins.
9. Raise lift cylinders and install transport lock pins in lower set of holes in the vertical tubes for transport. Store
pins in the upper set of holes during operation.
10. Repeat steps 1-9 to purge air from the coulter toolbar lift cylinders.
NOTE: After purging the hydraulic system, check adjustment and operation of transport wheel rollers. These
rollers must turn when the cart is lowered or raised. Adjust the rollers as necessary.
