Cleaning the truck
Note on flame proof enclosures
Depending on the category of the truck, it can
be equipped with one or more flame proof en-
closures. These flame proof enclosures con-
tain components of the truck control unit and
other electrical and electronic components.
DANGER
Risk of explosion due to improper han-
dling!
The pressure-tight housings have a
specified gap between the cover and
housing. Improper opening and closing
of the pressure-tight housings can cause
a detrimental change to this gap. Poten-
tially explosive substances in the atmos-
phere can penetrate the housing during
operation in at-risk areas; this can cause
an explosion, which can in turn spread to
the surrounding environment.
–
Do not open pressure-tight housings.
CAUTION
If water penetrates the electrical system,
there is a risk of a short circuit occurring!
The flame proof enclosures have a nar-
row gap that could allow water to pene-
trate.
–
Do not use high-pressure cleaning
equipment.
