dried.

Corroded places should be cleaned of rust, degreased and protected using
undercoat paint and then painted with surface paint according to colour scheme.
•
In the event of a prolonged work stoppage, it is essential to lubricate all
components regardless of the date of the last lubrication.
•
Wheel rims and tyres should be carefully washed and dried. During longer
storage of unused trailer it is recommended that every 2 to 3 weeks the machine
may be moved a bit so that the place of contact of tyres with ground is changed.
The tyres will not be deformed and maintain proper geometry. Also, air pressure
in tyres should be inspected from time to time and, if necessary, pressure should
be increased to appropriate value.
