Travel Forum / Travel Types / RV Travel / January 2006Big Foot Jacks
Got a question regarding my big foot jacks, last trip when getting ready to leave from the camp grounds I raised my jacks and started the engine the alarm came on the alarm did not shut down and I went out side and checked and all 4 jacks and they were up so crawled underneath to check it all out and could find nothing wrong. Decided since the jacks were up and I did not know what was wrong I started driving home, stopped a couple of times within the first few miles and checked the jacks were still up and the alarm was still sounding. But then a few more miles down the road the alarm went away, ahhh peace and quiet. Made it back home and the other day I moved the MH and the alarm again came on even though the jacks were up. Any suggestions or tips will be appreciated. Lee What kind of Big Foot do you have? I at first assumed that you had a pickup camper, but now I am going to guess that you have a class C. Are the jacks hydraulic? I take it the alarm is supposed to go off if the the jacks are down and the motor is running.

Each of the pumps are independent of each other. Yes to the alarm and also has flashing lights for each of the jacks. What was funny was that the alarm and the lights finally went off when I was a few miles down the road. These jacks are approximately 7 years of age and I have had the lines replaced also. Thanks for any ideas! Lee Lee somehow found the right keys to write: >> What kind of Big Foot do you have?

The BigFoot system, retracts under power, and the limiter switch wouldn't shut the pumps down were that the case. HWH retracts with springs, by simply opening a valve and allowing the springs to retract the system. Lee has the Bigfoot system.

They obviously work, or you would have noticed that the pump keeps running even after the jacks are retracted. I would check the wire connections at those switches. I suspect corrosion.

Hi Lon Say hi to your wife Carolyn also. Yep only my shiny metal pins are now of the rusted variety after all those 7 years. And yes they shut off the individual pumps as they are seated. Funny thing is that 3 of the 4 were in the alarm stage and not the 4th so apparently you may be right, I will wait a day or so till it warms up a little before climbing under that 10 to 12 inch clearance Not to much room to work and plus I have to loosen the bolts on 1 jack to realign it. All of this happened during our 3 weeks up in Georgia. First time also. As I said I will check it out and hopefully something will work right. Thanks for the suggestion. Maybe a little 10W40 will help out also.

Have you checked the fluid level. I don't have Big Foot jacks but do have Power Gear and usually when the alarm continues to sound after the jacks are raised is an indication of low fluid level.

I'm Sure you know this, but just in case! Never add fluid with any jack(s) extended, it will cause you to lock up the system. Check fluid levels with the jacks "Stored" completely.

If too much oil is added when the jacks are extended, a quick retraction will squirt fluid out the top. This is a small problem with the front jack that are inside. A small rag on top solves that problem. Wiping off the stainless cylinder is recommended. The Bigfoot people recommend silicon and wiping it dry. They don't recommend anything that may attract dirt such as WD 40 although I know lots of people who swear by WD 40.

Hell, Bill! You use it for what it was designed!

My advise came from HWH Jack experience, where a servo opens a valve to let the springs retract the jacks. No pressure to burst any obstructed lines and so on, but it will not push oil out of the system because the system is sealed ... maybe so it won't absorb water from the air < LOL > Cliff in FL Signature"The more you know, the less often you get killed!" Our Web Page http://www.cj-and-m.com >>> Our Web Page http://www.cj-and-m.com >>> [quoted text clipped - 9 lines] > absorb water from the air < LOL > > Cliff in FL The system I was talking about is the HWH, examine the filler cap and you will notice that it is vented to allow for entry of air as the fluid level decreases and expelling air as the fluid returns. That same cap will also act as the overflow for excess fluid and is not sealed as we are only dealing with transmission fluid. >>> Got a question regarding my big foot jacks, last trip when getting >>> ready to leave from the camp grounds I raised my jacks and started [quoted text clipped - 12 lines] > levels with the jacks "Stored" completely. > Cliff - never had the problem, but have seen it LOL It will not cause you to lock up your system unless you replaced the bleeder valve that is designed to expel excess fluid |
