Popular hydraulic systems must store fluid under high pressure.
Three kinds of hazards exist: burns from the hot,high pressure spray of fluid; bruises, cuts or abrasions from flailing hydraulic lines and hydraulic injection of fluid into the skin.
Safe hydraulic system performance requires general maintenance.
Proper coupling of high and low pressure hydraulic components and pressure relief valves are important safety measures.
Follow these rules for safe hydraulics operation.
* Always lower the hydraulic working units to the ground before leaving the machine.
* Park the machinery where children cannot reach it.
* Block up the working units when you must work on the system while raised; do not rely on the hydraulic lift.
* Never service the hydraulic system while the machine engine is running unless absolutely necessary (bleeding the system).
* Do not remove cylinders until the working units are resting on the ground or securely on safety stands or blocks; shut off the engine.
When transporting the machine, lock the cylinder stops to hold the working units solidly in place.
* Before disconnecting oil lines, relieve all hydraulic pressure and discharge the accumulator (if used).
* Be sure all line connections are tight and lines are not damaged; escaping oil under pressure is a fire hazard and can cause personal injury.
