HYDRAULIC FLUID
WARNING: HYDRAULIC FLUID can result in severe
burns. Fluid in hydraulic system can penetrate skin and
result in serious injury or death.
Be sure to stop the engine before doing any work on
hydraulic parts.
Keep body and hands away from pin holes or nozzles
which expel hydraulic fluid when under pressure. Use
paper or cardboard, not hands, to search for leaks.
Ensure all hydraulic fluid connections are tight and all
hydraulic hoses and lines are in good condition before
applying pressure to system.
FOREIGN FLUID INJECTED INTO BODY can result in
gangrene. Fluid must be surgically removed within a
few hours by a doctor familiar with this form of injury.
