 |
An upstroke of the jack handle draws oil into the pump cylinder. | |||
 |
A downstroke of the jack handle pushes pressurised oil to the main cylinder causing it to raise the main piston. | |||
 |
After constant pumping of the jack the check valves will open and close with each motion. | |||
 |
The main piston keeps raising as the jack is pumped. | |||
