Case 621G Stage IV Service Manual page 14

INTRODUCTION
When hydraulic oil has been swallowed, avoid vomiting,
but consult a doctor or go to a hospital.
If an accident occurs, see a doctor familiar with this type
of injury immediately.
Any fluid penetrating the skin must be removed within a
few hours to avoid serious infections.
Flammable splashes may originate because of heating
near lines with fluids under pressure, resulting in serious
burns. Do not weld or use torches near lines containing
fluids or other flammable materials.

Lines under pressure can accidentally be pierced when
the heat expands beyond the area immediately heated.
Arrange for temporary fire resistant shields to protect
hoses or other components during welding or torch use.
Have any visible leakage repaired immediately.
Discharged oil pollutes the environment. Soak up any
oil that has spilled with a proper binding agent. Sweep
up binding agent and dispose of it separately from other
waste.
Never search for leakages with fingers; instead, use a
piece of cardboard and always wear goggles.
Never repair a damaged line; always replace it. Replace
hydraulic hoses immediately on detecting any damaged
or moist areas.
Always store hydraulic oil in the original containers.
