2. Maintenance Intervals
•Maintenance Intervals:
In a modular structure, the Minuteman System Maintenance determines the specific
technical proceedures to be preformed and sets the time interval between the two
maintenance cycles.
For each of the maintenance cycle, the replaceable parts are determined as well.
Further details described in the specific chapters.
•Minuteman System Maintenance K:
To be performed by the customer (in daily or weekly intervals) according to the maintenance
and care instructions as specified in the operating instructions.
The operator must be professionally instructed after delivery of the machine by selling
dealer.
•Minuteman System Maintenance I: (after every 125 hours of operation)
To be preformed an authorized Minuteman Service Center in accordance with the machine-
specific system maintenance.
•Minuteman System Maintenance II: (after every 250 hours of operation)
To be preformed an authorized Minuteman Service Center in accordance with the machine-
specific system maintenance.
•Minuteman System Maintenance S: (after every 500 hours of operation, safety check) To
be performed by an authorized Minuteman Service Center in accordance with the machine-
specific system maintenance. Page 5
