7.1
Periodic maintenance
Repairs must only be carried out by the manufacturer.
Only use original parts (see chapter 10 "Accessories").
Cleaning the units and checking the liquid levels is the only periodic maintenance
required. With normal use, no further maintenance should be necessary. If required,
the system can be returned to the manufacturer for re-conditioning. Accuracy, overhaul
and recertification are also explained in chapter 7.4.1 "Overhaul and recertification of
dead-weight testers, maintenance of accuracy".
Liquids, which attack ABS, should be used with caution. Continuous
immersion of the case cover in such liquids will cause damage. Spillages
should be wiped off immediately.
