210 Inspection, care and maintenance
Galvanised steel surfaces
Galvanised surfaces / components
(e.g. chassis, tow bar) must first oxidise
in order to develop corrosion protection.
This may take several months.
A corrosion protection layer has only
been formed when the surface has lost
its zinc gloss.
White rust may form on zinc-coated
surfaces.
This is promoted by wetness / high air
humidity and substances such as grit.
White rust is not a fault or damage to the
surface - it cannot be prevented by the
zinc-coating workshop and is therefore
no basis for warranty claims.

Immediately clean the zinc-coated
components with clear water after
they have come into contact with
aggressive substances.

Let the surfaces dry out well.
For white rust treatment:

Clean the affected areas with lots of
clear water and thoroughly dry them.

Remove the white rust stains with a
nylon brush.

Apply zinc protection (zinc spray) to
the affected areas.

Seal the surfaces with wax as
required.
Painted and powder-coated steel
surfaces
Painted surfaces / components
(e.g. cargo bed, drop sides) provide
moderate corrosion protection.
Painted surfaces / components that are
directly exposed to the effects of brake
dust, loose chippings, de-icing salt, sand,
etc. require particularly intense care - to
make the painted surfaces look visually
appealing and to protect them
permanently against corrosion.

Clean the painted surfaces after every
exposure to surface-corroding
substances.

Let the surfaces dry out well.

Seal the surfaces with wax as
required.

Paint damage (chipped off, scratched)
on the surface should immediately be
mended by qualified specialist
personnel.
