1.5 OTHER MAINTENANCE PROCEDURES
WASHING THE ATTACHMENT
When working with attachment and removing it from the carrier, dirt (mud, rock
powder etc.) can become attached to it. Wash the outside of the product with a steam
washer before sending it to the workshop. Dirt can cause difficulties in disassembly
and assembly otherwise.
CAUTION! Plug the pressure and return line and other connections before washing
the product or else dirt can enter into it and this may cause damage to the
components.
