WARNING
Burn and Inhalation Hazards!
Avoid possible injury. The temperature of exhaust and
exhaust components for a Tier 4F engine can be higher
than other engines and can cause serious burns.
Avoid physical contact with the exhaust gases and the
exhaust system components. Exhaust gases are harmful
to your health.
Keep all flammable materials away from the exhaust
system to prevent fire.
If it is necessary to service the crane while the engine is
running, inhibit (turn off) SCR regeneration using the
switch in the cab to prevent a higher exhaust temperature.
