4.8 CLEANING OF THE TRAILER
The trailer should be cleaned depending
on demand and before a longer standstill
(e.g. before winter). The use of a pressure
washer obliges the user to become fa-
miliar with the principle of operation and
recommendations for the safe operation of
this device.
THE SCOPE OF ACTIVITIES
• Before washing the trailer, open the
tailgate. Thoroughly clean the load
box from any cargo residues (sweep
or blow with compressed air), espe-
cially around the tailgate adjacent
and extensions.
• To clean the trailer, use only clean
running water or water with a cleaning
detergent additive with a neutral pH.
• The use of pressure washers in-
creases the effectiveness of washing,
but be careful when work. During
washing, the nozzle of the cleaning
aggregate must not be closer than 50
cm from the surface being cleaned.
The water temperature should not
exceed 55
C
o
• Do not direct the water jet directly at
the elements of the installation and
equipment of the trailer, i.e. control
valve, braking force regulator, brake

leaves, points lubricating trailers,
etc. High pressure water jet may
cause mechanical damage to these
components.
• For cleaning and maintenance of
plastic surfaces, it is recommended to
use clean water or specialized prepa-
rations intended for this purpose.
• Do not use organic solvents, prepa-
rations of unknown origin or other
substances that may damage the lac-
quered, rubber or plastic surface. It is
recommended to make a test on an
invisible surface in case of doubt.
• Surfaces oily or greasy by grease
should be cleaned with petrol or de-
greasing agents, and then washed
with clean water and detergent.
Follow the cleaning agent manufac-
turer's instructions.
• Detergents intended for washing
should be stored in their original con-
tainers, or alternatively, but marked
exactly. The preparations cannot
be stored in containers intended for
