Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.

lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.

hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
• Get immediate medical help if fluid is injected
into skin.
