There is an access door for the dozer/ripper valves on the right side of the machine. Open the access door.This procedure requires two people. One person must operate the control valves and the other person remains at the dozer blade. Care must be taken when you perform this procedure. The person at the dozer blade must make sure that the area is clear.

Loosen locknut (1A) and turn adjustment screw (1) inward. Note: After completing the dead engine lower for each function, back out the adjustment screw fully. Then, tighten the locknut.Note: Before you screw in all dead engine lower screws, clean all the dirt and paint from the adjustment screw.Note: Perform steps 2 through 4 in order to change the angle or lower the equipment.
Loosen locknut (2A) and turn adjustment screw (2) inward. This relieves head pressure to the right angle cylinder and rod pressure to the left angle cylinder. This angles the dozer blade to the right.
Loosen locknut (3A) and turn adjustment screw (3) inward. This relieves head pressure to the tilt angle cylinder. This tilts the dozer blade to the right.
Loosen locknut (4A) and turn adjustment screw (4) inward. This relieves rod pressure from the ripper cylinder to the tank. This raises the ripper.
Loosen locknut (5A) and turn adjustment screw (5) inward. This relieves rod pressure from the lift cylinder to the tank. This lowers the dozer blade.
Loosen locknut (6A) and turn adjustment screw (6) inward. This relieves rod pressure to the right angle cylinder and head pressure from the left angle cylinder to the tank. This angles the dozer blade left.
Loosen locknut (7A) and turn adjustment screw (7) inward. This relieves the rod pressure from the tilt cylinder to the tank. This tilts the dozer blade left.

Anti-drift valve
Before releasing pressure on the fourth valve (8, 8A) , completely back off adjustment screw on anti-drift valve (9) . This will make sure that the pressure is fully released.
Mark the location of the adjuster valve. Then, back off the adjustment screw completely.
Loosen locknut (8A) and turn adjustment screw (8) inward. This relieves the head pressure from the ripper cylinder to the tank. This lowers the ripper.Close the access door. Close the hydraulic oil tank cap.Note: After completing the work for the dead engine lower, cycle each section of the implement valve 10 times in order to remove any air from the valve sections.
