General Maintenance Information
The GLOBAL S measuring machines were designed and built in such a way as to ensure reliable operation
and minimum maintenance requirements.
The maintenance operations must in any case be performed by trained engineers, i.e. by persons with
technical know-how or experience, or who have received specific instructions about the maintenance
operations to be performed.
Preventive Maintenance
The preventive maintenance operations described in this chapter are to be carried out by the Customer.
All preventive maintenance operations must be performed with great care so as not to cause a deterioration
in the functioning and performance of the measuring machine.
These operations are to be performed at the frequency suggested in the preventive maintenance schedule.
However, the specified frequency may be adapted to the environmental conditions of the installation site
and the number of hours the measuring machine is operated.
Extraordinary Maintenance
Extraordinary maintenance operations are not described in this chapter. They must be performed by
specially trained engineers. We recommend that you contact the Hexagon customer service.
Hexagon Customer Service
In order to ensure that the machine is kept in optimum operating conditions, we suggest you stipulate a
maintenance contract with the Hexagon customer service.
Preventive Maintenance Intervals
The recommended intervals for preventive maintenance are Daily, Monthly and Quarterly. These intervals
are based on eight hours per day and forty hours per week of machine operation.
If the machine operates for more than eight hours a day or five days a week, the maintenance schedule
should be adjusted as follows:
Daily or every 8 hours of operation
Monthly or every 165 hours of operation
Quarterly or every 500 hours of operation
Every five months or every 850 hours.
For example, if a machine is operated for two eight-hour shifts per day, monthly maintenance should be
carried out every two weeks. If the machine is used less than eight hours per day or less than five days per
week, the regular Daily, Monthly, and Quarterly schedules should be changed accordingly.
