Burn Prevention
SMCS Code: 1000; 7405
Do not touch any part of an operating engine system. The engine, theexhaust, and the engine aftertreatment system can reach temperaturesas high as 650 °C (1202 °F) under normal operating conditions. If theengine or the engine aftertreatment system unexpectedly fails, the
temperature of the gas at the diesel particulate filter (DPF) may increaseto 900°C (1652°F).
At idle engine speed and/or zero vehicle speed, an operator can request amanual regeneration. Under this condition, the exhaust gas temperaturecan reach 650 °C (1202 °F). Otherwise automatic regeneration canproduce exhaust gas temperatures as high as 450 °C (842 °F).
Allow the engine system to cool before any maintenance is performed.
Relieve all pressure in the air system, in the hydraulic system, in thelubrication system, in the fuel system, or in the cooling system before anylines, fittings or related items are disconnected.
Coolant
When the engine is at operating temperature, the engine coolant is hot.The coolant is also under pressure. The radiator and all lines to theheaters or to the engine contain hot coolant.
Any contact with hot coolant or with steam can cause severe burns. Allowcooling system components to cool before the cooling system is drained.
Check the coolant level after the engine has stopped and the enginehas been allowed to cool.
Ensure that the filler cap is cool before removing the filler cap. The filler cap must be cool enough to touch with a bare hand. Remove the filler capslowly in order to relieve pressure.
