Fine jets of hydraulic fluid at high pressure can penetrate
the skin. Do not use your fingers to check for hydraulic
fluid leaks. Do not put your face close to suspected
leaks. Hold a piece of cardboard close to suspected
leaks and then inspect the cardboard for signs of
hydraulic fluid. If hydraulic fluid penetrates your skin, get
medical help immediately.
