SAFETY INSTRUCTIONS
General information
Working with engines and the necessary service products does not pose any problems provided the people
entrusted with operation, maintenance and repair have been trained accordingly and actively keep their minds
on the job.
Personnel in training or instruction or who are undergoing general education are not allowed to work on the
unit unless they are permanently supervised by an experienced person.
The following sections include summaries of important regulations listed according to major topics. The
intention is to provide the knowledge needed to avoid accidents which could lead to injury, damage and
environmental pollution.
They represent only a small excerpt from the wide range of accident prevention
regulations and cannot replace these. It goes without saying that all other safety regulations must be
followed and that the corresponding action must be taken.
Additional direct references to danger are contained in the instructions at points where there is a potential
danger.
Accidents may happen in spite of all precautionary measures having been taken. In such an eventuality,
obtain immediate medical assistance from a doctor. This is particularly important if the accident involves skin
contact with corrosive acid, fuel penetration under the skin, scalding by hot oil, antifreeze spraying into eyes,
etc.
