What to do if the Joerns Lifting Systems jack lowers with a patient suspended?
If the jack lowers while a patient is suspended, it might be due to the check valve not sealing properly. First, ensure that the pressure release knob is completely closed. Then, pull down on the boom a few times to try and reseal the valve. If the problem persists, the jack may need to be replaced.
Why Joerns Lifting Systems jack fails to lift to full height?
If the jack isn't lifting to its full height, it could be due to air trapped in the oil under the ram or low oil levels. Try pumping the unit as far as it will go, then open the pressure release knob and repeat this process until the lift reaches its full height. If that doesn't work, remove the jack, collapse the ram, remove the socket screw, and add hydraulic oil (#10 weight) one ounce at a time until full.
