Introduction
Coolant Precautions
FIG. 17: When engine’s 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 pin hole 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.
FIG. 19: Use a piece of cardboard or wood to search for
possible leaks, never use hands.
IMPORTANT: Ensure fluids are contained during
performance of inspection, maintenance, testing,
adjusting and repair of machine. Be prepared to
collect fluid with suitable containers before
opening any compartment or disassembling any
component containing fluids. Dispose of all fluids
according to local regulations and mandates.
Do not bend or strike any high-pressure line. Do not install
any lines bent or damaged.
Check lines, tubes and hoses carefully. Repair loose or
damaged lines. Tighten all connections to recommended
torque.
Replace parts if any of the following conditions are
present:
• End fittings are damaged or leaking.
• Outer coverings are chafed or cut.
• Wires are exposed.
• Outer covering is ballooning.
• Flexible parts of hoses are kinked.
