•
Before beginning repair works on hydraulic or pneumatic systems reduce oil or air
pressure.
•
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's
engine switched off and the ignition key removed. Tractor and trailer should be
secured using parking brake and in addition chocks should be placed beneath
trailer wheel. Ensure that unauthorised persons do not have access to the tractor
cab.
•
Should it be necessary to change individual parts, use only original parts. 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 guarantee.
•
Regularly check technical condition and mounting of all guards and protective
elements.
•
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. Load cell shall be dismantled (in the event of
electric welding), if not, it may be damaged. 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.
•
In the event of work requiring the trailer to be raised, use properly certified
hydraulic or mechanical lifts for this purpose. After lifting the machine, stable and
durable supports must also be used. Work must not be carried out under a trailer,
which has only been raised with a lift or jack.
