Filling hydraulic reservoir

The Black Tank on the bottom is the fluid tank, the caps above it in the silverish metal are there to hold the magnets on the assorted valves.

I do not see a filler cap.. I do not recommend removing the float valve but it may be that is how you do yours. The filler should be on the TOP of the black tank with the yellow/orange sticker on it and the POWER GEAR label.

From the picture, it appears your jack system is made by Power Gear. I have Power Gear jacks on my 2000 HR. Mine has a vertical tank, but not exactly like the picture, but with a float switch generally in the same position.

If the unit is slightly low on fluid, it will perform correctly when not in motion. Retracting jacks will work and turn off the "jacks down" light. When in motion, however, that slightly low fluid will trigger the "jacks down" light and alarm. Power gear senses "jacks up" by the position of the float switch.

Add a little fluid and I'll bet your problem goes away.

PS...I've never seen a tank like that without a fill plug. Mine has a float switch and a separate fill plug. I looked at the Power Gear troubleshooting guide and it has a picture of vertical tanks 2003 and up and that picture has a float switch and a fill plug. I could find nothing in the troubleshooting guide with a tank like your picture.

Thank you. The two things on top are actually fill plugs with dipsticks. It was low. I overfilled it of course. Made a mess but I think I'm good.....

Thank you all for the help.

I agree with what Mike said here. The warning buzzer is most likely to do with a sensor that is indicating one or more of the jacks are not fully retracted. No warnings for low hydraulic fluid on a leveling system that I have ever hear of.

When you retract your jacks, do you allow them to shut off automatically after retracting, or do you push the jacks power off button after they have retracted?

Ok. You guys are correct. It is not the fluid level. I allow lots of time for the jacks to fully retract. The "jacks down" light goes off. It only does it when the coach "leans". I'm leaning towards the sensor that you and Mike talked about. Do you know where it is? How would I check it? Or do I just replace and see what happens?

Thanks

You fill it at the float level switch. The threaded plug with the red wires attached. Mark the plug so that it is in the same position when you replace it. And yes, be sure the slides are in when checking/adding fluid. :)

Thank you...

Are the two caps on the top where I fill?
