7.3 Changing the insulation fluid
NOTICE
Damage to the on-load tap-changer!
Small parts in the oil compartment may block the diverter switch insert,

► Ensure that parts do not fall into the oil compartment.
► Check that all small parts are accounted for.
Change the insulating fluid in the on-load tap-changer oil compartment and
oil conservator if the dielectric strength and water content are not in compli-
ance with the limit values specified in the technical data.
