I have a few bottle jacks which were left on their side for a while and are now refusing to lift machinery, when you pump the handle, piston extends and then falls again. 20ton jacks are refusing to lift 200kg.
From what I read/google there is air in the jacks.
Anyone got a quick and easy way for removing it so jack will be of use again.
