specifications, wear tolerances, and torque
values. Technical Manuals are concise guides for
specific machines. They are on-the-job guides
containing only the vital information needed for
diagnosis, analysis, testing, and
repair. Fundamental service information is
available from other sources covering basic
theory of operation, fundamentals of

• PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is
  poisonous. It is strong enough to burn skin, eat
  holes in clothing, and cause blindness if
  splashed into eyes.
• Avoid the hazard by
• Filling batteries in a well-ventilated area.
• Wearing eye protection and rubber gloves.
• Avoiding breathing fumes when electrolyte is
  added.
• Avoiding spilling or dripping electrolyte.
• Use proper jump start procedure.
• If you spill acid on yourself
• Flush your skin with water.
• Apply baking soda or lime to help neutralize the
  acid.
• Flush your eyes with water for 1015 minutes. Get
  medical attention immediately.
• If acid is swallowed
• Drink large amounts of water or milk.
• Then drink milk of magnesia, beaten eggs, or
  vegetable oil.
• Get medical attention immediately.

AVOID HIGH-PRESSURE FLUIDS Escaping fluid under
pressure can penetrate the skin causing serious
injury. Avoid the hazard by relieving pressure
before disconnecting hydraulic or other lines.
Tighten all connections before applying
pressure. Search for leaks with a piece of
cardboard. Protect hands and body from high
pressure fluids. If an accident occurs, see a
doctor immediately. Any fluid injected into the
skin must be surgically removed within a few
hours or gangrene may result. Doctors unfamiliar
with this type of injury should reference a
knowledgeable medical source. Such information is
available from Deere Company Medical Department
in Moline, Illinois, U.S.A. DX,FLUID -19-0
