Hi.. here is the situation:I have purchased a hydraulic 2ton engine hoist and it would not lift an engine, it would hold weight however would not raise it... I figured there was not enough fluid so I phoned a friend of mine who recommended to use automatic transmission fluid... after trying this i figured out that transmission fluid is not hydraulic fluid and should not be used in a hoist like this one.. After the trans fluid mixed with the hydraulic fluid the hoist would no longer hold weight it would leak down slowly and would not raise properly.. Today I drained out all the fluids from it and got air into the system.. now the piston is ceased at half way and will no longer go up or down (no fluid just air inside). Is there a way to extract the air from inside the system or do i have to purchase a new one for 59.99? Thanks.
i would/my arms and other fixed parts of my body is worth 60 bucks
You have probably swollen the internal seals. Before giving up try removing the oil fill plug and manually pushing down the piston. By now you know why you should only use hydraulic jack oil. Also be aware that the boom arm is usually adjustable the shorter it is the more lifting force there will be.
