How To Bleed or Air Purge a Trolley Jack

Why You Need to Air Purge Your Trolley Jack

Even though a trolley jack is a closed system that relies on hydraulic pressure to generate lift, air can still become trapped in the hydraulic system and affect performance.

If your trolley jack is not lifting, not fully lifting or feels "spongy" then there may be trapped air in the system. There is however a very simple procedure to follow to purge any air from the jack and keep your jack working correctly.
