7.1 Aim of maintenance
Maintenance can be divided into two categories:

corrective maintenance.
Preventive maintenance is all maintenance necessary to keep the machine in a
good condition or returning it to that condition.
Corrective maintenance is done after malfunctions have occurred.
Always follow maintenance instructions.
All maintenance actions described must be done on schedule. Due to load
differences and environmental influences certain parts may require more or less
maintenance than specified.
The maintenance procedures will refer to special instructions when necessary.
