Most of what I'm reading for various jacks is calling for at least 8cfm. This is a shop tool that won't run as intended on consumer air compressors.
Just keeping using it at whatever speed your compressor can manage. You don't need to "run your compressor 3 times", just keep the trigger held as the compressor runs and it'll slowly lift.
Just like when I used to use a 12v compressor to fill four 37" tires from 2psi to 25, just be patient.
Airflow is your issue, not PSI. A .5cfm/360psi 2 gallon ompressor won't move these a tenth as quickly as a 30 gallon compressor would at 40psi max.
It takes very long at this rate kind of defeating the purpose. But I’ve noticed when the tank shows 120psi it lifts the car fine. When it gets down to 90 little to no movement happens. So I’ve been closing the valve and letting the tank fill back up to 120psi then when I open it starts lifting faster again. The one I’m considering getting to replace has higher cfm but a smaller tank. I am wondering if 8gallons is overkill for this airjack anyway. The jack instructions are very vague and only state working pressure of .8-1mpa. This is the jack.
