DUMP BODY HEATING SPECIFICATIONS
The dump body heating is a function to improve the removal of soil from the dump body by heating the dump
body with the exhaust gas.
If the dump body heating specification is employed, the machine can obtain outstanding easiness of dumping
when the operation is performed in the freezing area.
After the aftertreatment devices regeneration, the temperature of dump body may rise 250 °C or higher because
of the exhaust gas.

CAUTION
For the machines equipped with dump body heating specification, the dump body becomes highly heat-
ed during the aftertreatment devices regeneration.
Stay away from the dump body to prevent burn injury.
If the following objects are loaded, fire may occur.
• Objects which contains many combustible industrial wastes
• Objects which mainly contains combustible materials such as dry leaves, chips, pieces of paper,
and coal dusts
Take appropriate actions to prevent fire.
The temperature around the dump body becomes high as
shown in the figure.
Remedy to prevent fire
When loading the combustible materials, change the machine specification to the specification without dump
body heating.
Contact your Komatsu distributor for changing the machine specification to the specification without dump body
heating.
In case the combustible materials are loaded, momentarily avoid a fire in the following procedure.
1.
Avoid the automatic regeneration by performing regeneration disable operation after the engine is started.
2.
After finishing the work, perform the manual stationary regeneration while the machine is unloaded.
REMARK
Mixing a large amount of soil into the combustible materials helps to decrease the fire.
