Gear didn't extend or retract fully

[hharney]

There's a sight gauge on the left side just below the storm window but it's 99% of the time completely worthless. On the left firewall there is a pipe fitting just above the battery box that allows to fill the hydraulic tank. Fill with 5606 until it exits below from the overflow. Do this with the gear retracted on jacks. If this is done with gear extended you will overfill the tank and during the first retract it makes a big mess, ask me how I know.
