:
These intervals refer to normal working conditions. For heavy use decrease the interval for each job.
For maintenance and/or repairs, use only original spare parts which offer the greatest characteristics of quality and
reliability. Failure to use original spare parts absolves the manufacturer from all liability and transfers it to the
person carrying out the operation.
