Remove the hose from the 90° fitting installed into the male quick coupler removed in Step #1.2. Install the -12 male pipe x -12 female JIC Swivel fitting into the end of the control valve on the side the arrow is pointing to.3.
Attach the 90° fitting with the male quick coupler still attached to the JIC Swivel fitting that was installed in Step #3.4.
Install the -12 male pipe x -12 male JIC Straight fitting into the end of the control valve on the side opposite that the arrow is pointing to.5. Attach the end of the original hose to the fitting attached in Step #5. See diagram below for further clarification on orientation of the control valve.6.
Plug male quick coupler back into the tractor7. To adjust the control valve, unscrew the adjusting knob at the top of the valve. Run the the lift cylinders up and down.8. Adjust the lift speed by turning the adjusting knob back in with 1/2 turn incrments.9. After each 1/2 turn, run the lift cylinders up and down. Continue to do this until the desired speed is achieved and there is no chatter or cavitation.10. After the control valve is adjusted, lock the adjusting knob with the lock screw.11.

Note: Your system may look slightly different from the diagram shown above but all lift systems are plumbed so that the rod end of both cylinders come to a t-fitting and then run to the back of the tractor and hook up to the SCV - UP. The base end of both cylinders come to a t-fitting and then run to the back of the tractor and hook up to the SCV - DOWN.
