3.0 Transport and storage
3.1 Transport
Warning
The core drills are to be checked for signs for transport damage on receipt. Any
damage must be documented in writing.
1.1
Storage
If possible, the storage site should be dry, clean and have a constant temperature. To ensure that the film
of lubricant in the bearings and sealing system is not lost, the motor shaft should be turned through several
revolutions by hand after a lengthy period of storage, for example at monthly intervals. The roller bearings
in the motors should be replaced (or regreased) if the period between delivery and commissioning is over
four years. If the machines are stored in adverse conditions, this period may differ considerably.
