Stationary Regeneration Precautions - Blue Bird D3RE 2014 Driver's Handbook Manual

Stationary Regeneration Precautions

During active regeneration, the exhaust system can reach extremely high temper-
atures. Automatic active regeneration, which occurs while driving the bus, is pro-
grammed to occur only when the bus is moving at a minimum speed, and it stops
when the vehicle slows or stops.
With the Cummins engine, the HEST indicator appears whenever the high tem-
perature condition exists.
When performing a Stationary Regeneration, the entire process occurs for an
extended period while the bus is stopped. It is therefore critical that prudent human
safety and fire hazard precautions are followed. Those precautions include:
• Read, understand, and abide by all the precautions pertaining to regeneration
procedures in the engine manufacturer's Operator's Manual.
• If at all possible, the Stationary Regeneration procedure should be conducted
at a service facility by trained technicians.
• The Driver's first priority is the safety of the passengers. If a Stationary Regen-
eration must unavoidably be done by the Driver under a qualified technician's
direction, alternate transportation should be arranged first, or passengers
should be removed under proper supervision to a location away from the
bus.
• Select an appropriate location to park the vehicle.
• Choose a surface that will not burn or melt under high temperature,
such as clean concrete or gravel, not grass or asphalt.
• Ensure that nothing that can burn, melt, or explode (gasoline, wood,
paper, plastics, fabric, compressed gas containers, hydraulic lines) is
near the exhaust outlet. Abide by all instructions, warnings, and cau-
tions in the engine manufacturer's operator's manual regarding safe
operation when performing a Stationary Regeneration.
• Park the bus securely.
• Set the parking brake. Put the transmission in Neutral. Chock the
wheels.
