Introduction
Burn Hazards
FIG. 16: Do not touch any part of an operating engine.
Other components such as transmission, axles and oil
reservoir may be hot. Allow engine to cool before any
maintenance is performed. Relieve all pressure in air, oil,
lubrication, fuel system or cooling system before any line,
fittings or related items are disconnected.
Coolant Precautions
FIG. 17: When engine is at operating temperature,
engine coolant is hot and under pressure. Radiator and all
lines to heaters or engine contain hot coolant.
Any contact with hot coolant or steam can cause severe
burns. Allow cooling system components to cool before
cooling system is drained.
Check coolant level only after engine has been stopped.
Cooling system conditioner contains alkali that can cause
personal injury.
Do not allow alkali to contact skin, eyes or mouth. Do not
remove radiator cap if engine is hot. Only remove cap
when it is cool enough to touch with bare hands. Loosen
cap slowly to first notch to relieve pressure, then remove
cap.
Escaping Fluid Dangers
FIG. 18: Escaping fluid under high pressure can be
almost invisible but can penetrate skin causing serious
injury and possible death. A pinhole leak can cause
severe injury.
Consult a doctor immediately if an injury from escaping
fluids is sustained. Fluid injected into skin must be
surgically removed within a few hours or gangrene may
result.
Hot oil and hot components can cause personal injury.
