•
Before beginning work, which requires raising the load box, it should be emptied
and secured with the support leg. The trailer must at this time be hitched to the
tractor and secured with chocks and parking brake.
•
Before beginning repair works on hydraulic or pneumatic systems reduce oil or air
pressure completely.
•
Servicing and repair work should be carried out in line with the general principles
of workplace health and safety. In the event of injury, the wound must be
immediately cleaned and disinfected. In the event of more serious injuries, seek a
doctor's advice.
•
Repair, maintenance and cleaning work should be carried out with the tractor
engine turned off and the ignition key removed. Tractor and trailer should be
secured using parking brake and in addition chocks should be placed beneath
trailer wheels. Ensure that unauthorised persons do not have access to the tractor
cab.
•
During maintenance or repair work, the trailer may be unhitched from tractor, but
it must be secured with chocks and parking brake. During this work the load box
may not be raised.
•
Should it be necessary to change individual parts, use only those parts indicated
by the Manufacturer. Non-adherence to these requirements may put the user and
other people's health and life at risk, and also damage the machine and invalidate
the warranty.
•
Before welding or electrical work, the trailer should be disconnected from the
power supply. The paint coating should be cleaned. Burning paint fumes are
poisonous for people and animals. Welding work should be carried out in a well lit
and well ventilated space.
•
During welding work pay attention to flammable or fusible elements (parts of the
pneumatic, electric and hydraulic systems, plastic parts). If there is a risk that they
will catch fire or be damaged, they should be removed or covered with non-
flammable material before commencing welding work. Before beginning work,
prepare a CO or foam extinguisher.
