ROUTINE CONTROL AND MAINTENANCE OPERATIONS
AND SAFETY CHECKS
!
Caution!
1. The motor-sweeper must be inspected by a skilled technician who checks its safety or for any damage or de-
fects in the following cases:
•
before it is put into operation.
• after
modifi cations or repairs.
•
at regular intervals, as indicated in the “Routine maintenance and control operations” table.
2. Every six months check that the safety devices are in good working order.
To ensure that the safety devices are operating properly, the machine must be overhauled by specialist staff every
5 years.
3. The person in charge of the machine must make an annual check on its condition. During this check, he must
decide whether the motor-sweeper still complies with the technical safety regulations, and then apply a mar-
ker plate to the machine to indicate that the check has been made.
