2. With drill attached to tractor, jack drill up and

support frame at ends near gauge wheels.

3. With drill raised and supported, unpin cylin-

ders from gauge wheel arms and frame. Turn

cylinders "rod end up". Wire or otherwise

safely support rod ends higher than base

ends.

NOTE: In order to prevent trapped air pockets, rod

end must be higher than any other part of cylinder

during bleeding operation.

4. With tractor engine idling, engage tractor hy-

draulics to extend cylinder rods. When cylin-

der rods s are completely extended, hold

remote lever on for one minute.

5. Retract cylinders. Extend cylinders again and

hold remote lever on for one more minute. Re-

peat this step two more times to completely

bleed system.

6. Repin cylinders to drill frame and gauge

wheel arm with transport cylinder locks in

place. If any air still is trapped in either cylin-

der, the cylinder will have a spongy, erratic

movement and drill will not raise evely. If nec-

essary, repeat bleeding process.

7. Reﬁll tractor hydraulic ﬂuid reservoir to its

proper level.

NOTE: After the drill is raised, a slight settling will

occur due to the action of the rephasing cylinders.
