Hydraulic Oil Level Check
Wear effective eye protection and gloves. Fine jets of hydraulic oil at high pressure can penetrate
the skin. Do not use your fingers to check for hydraulic oil 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 oil. If hydraulic oil penetrates your skin, get medical help
immediately. Failure to follow this warning may result in injury or death to personnel.
