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.
