I changed the hose on my K plane and purged all of the old fluid out of it. Re filled with fluid as best as possible but now it appears to have an air bubble in it. Is there a proceedure for bleeding the air out? Thanks.

Keep cycling them up and down. The air will eventually escape. At least thats how mine work.

My lines leak a little. When they get spongy I just add more oil and cycle them up and down, they work the air out.

the rams should allow the air to cycle out w/ a few more ups and downs....

That sounds simple enough. I'll give a few more cycles and see what happens. Thanks.
