SAFETY PRECAUTIONS
HOT SURFACES AND FLUIDS
•There is always a risk of burns when working
with a hot engine. Be aware of hot parts like
the turbocharger system, the exhaust system,
hot coolant hoses, etc. Wait until the engine

grade of fuel can cause operating problems,
can cause the engine to stop and can cause
engine damage.
•Pay special attention to safe practices when
refueling.
PAINT DAMAGE
•Damage of the engine or parts paint during
maintenance and inspection can cause
corrosion. Any damage must be repainted
after inspection and maintenance.
WELDING ON ENGINE
