ENVIRONMENTAL RESPONSIBILITY

Scania has always been at the forefront in the development and production of 
environmentally safe engines. 

We have made great progress in reducing harmful exhaust emissions to be 
able to meet the stringent emission standards that are mandatory for almost 
all markets.

We have done this without compromising the high quality of Scania 
industrial and marine engines in terms of performance and cost effective 
operation.

To maintain these superior properties throughout the life of the engine it is 
important that the operator/owner follows the instructions of this manual as 
regards operation, maintenance and choice of fuel and lubricants. 

To further contribute to protecting the environment in service, maintenance 
and repair, ensure that harmful waste (oil, fuel, coolant, filters, batteries etc.) 
is disposed of and destroyed according to applicable local regulations.

This operator’s manual contains highlighted text urging you to protect the 
environment in different service and maintenance operations.

Refer to example

Always use suitable containers 

to avoid spillage when bleeding 

systems or renewing 

components.
