How to Bleed Standard Service and Bottle Jacks

A brand new jack out of the box can be tipped during transport which allows air to get into the system. To ensure proper use you want to make sure to bleed the jack before full use in your shop. Bleeding your jack monthly will keep it working in top performance. You should also bleed the jack if you see any decrease in lifting power.  Watch the video or read the steps below.
