If it is a small leak shooting the jack full of bearing/axle grease should fix it, it did mine, which happens to be a Power Gear jack. There should be a grease fitting on the housing just above the leg opening. You will need a grease gun to do this.
Powergear jacks with the Grease zirc are NOT for filling the jack full of grease. Injecting Grease in that Zirc will NOT inject grease into the jack. All it does is grease the lower seal. IF that lower seal is the source of the leak, adding grease to that seal will not stop the leak. The systems operate at 3000 psi. That will overcome any grease. Doug
Of course it doesn't "fill the jack" it greases the jack cylinder/housing and lubes the seals, and if the seals are dry and leaking a small amount of fluid, it stands to reason that lubing them can stop a leak, and in my case it did just that. I saw red fluid on the jack leg and collecting in the jack foot and after greasing, that went away.
As to the 3000 psi "overcoming" any grease, greasing is part of the maintenance listed in the Power Gear Manual. I have yet to see any grease blown out of the jack housing and clinging to the leg, that is what the seals are for to hold the fluid and the lube. If they are allowed to dry out, then like a dried out garden hose washer, you could get leaks.
