Bigfoot

[MrpJ]

Hi I have a Bigfoot levelling system fitted to my gulf stream
I need to know why
1. The front drivers side leg/jack keeps letting the RV. Down until all the weight is back onto the tyre
2. is it possible to check and if needed top up the one leg/jack or do they pump out from a main tank if so I can't find it

Can some one please help thanks

Welcome Mrpj to irv2.
You need to find your hydraulic tank and check the fluid level.
If its low you maybe pumping air into system.
Trace the jack line from one of your front jacks should show up at your tank pump.
When you find the tank fill to fluid level with all your jacks retracted not down.

Quadra (Bigfoot) makes both single pump and motor leveling systems and each corner has it own pump, motor and reservoir as does mine. If you have a plastic box like beside the leveling leg piston, then you also will find the reservoir for that jack under the plastic cover. The fluid level may have gotten low and air has gotten into the piston. Air is condensable and can be compressed which could be the cause of your problem. Check the fluid level with the jack retracted and fill the reservoir if need be. Run the jacks to full extension and retraction a few times to purger the air out of the jack. Make sure the jack is not leaking fluid as this will also cause the same issue. Keep us posted as to what you find.
