Training programme
Level I pneumatics
Power and control components for improved filling plant machine
maintenance and trouble shooting.
Candidates’ level:
This training is intended for candidates with good mechanical knowledge (as a minimum) and
even those with notions of mechanisation or automation. The knowledge may have been
acquired in the field or at school.
Purpose of the course:
The purpose of this training is to provide knowledge to make trainees capable of:
Understanding the pneumatics applied to machines in the filling line
Identifying all the pneumatic components of a machine
Understanding and making necessary adjustments
Carrying out programmed preventive maintenance on these machines
Making a logical approach to correcting faulty operation or breakdowns in
pneumatic circuits
