Principles Of Safe Technical Operation - PRONAR T400 Operator's Manual

CHAPTER 2
• Checking the tightening of the wheel nuts should be carried out after the first use
of the trailer, after the first journey with a load and then every 6 months of use. In
each case, the inspection activities should be repeated if the trailer wheel was
disassembled.
• Avoid damage of road surfaces, sudden and variable maneuvers, and high
speeds when turning.
• Regularly check tire pressure. Tire pressure should also be checked during all-
day intensive work. It should be taken into account that the increase in tire
temperature can increase the pressure by up to 1 bar. With such a rise in
temperature and pressure, reduce the load or speed. Never reduce pressure by
venting the tire if it increases due to temperature.
• Tire valves should be protected with suitable caps to avoid penetration of dirt.

2.1.8 PRINCIPLES OF SAFE TECHNICAL OPERATION

• During the warranty period, any repairs may only be carried out by a warranty
service authorized by the manufacturer. After the warranty period, it is
recommended to carry out any repairs to the trailer in a specialized workshop.
• In the event of any failure or damage whatsoever, do not use the trailer until the
time of repair.
• During maintenance work, use appropriate, close-fitting protective clothing, gloves
and appropriate tools. In the case of work with the hydraulic installation, it is
recommended to use oil resistant gloves and protective glasses.
• Any modification to the trailer releases PRONAR Narew from liability for damage
or injury.
• Regularly check the technical condition of safety devices and correct tightening of
screw connections (in particular drawbar eyes, wheels).
• Carry out the inspections of the trailer according to the frequency specified in this
manual.
• Before starting repair work on hydraulic or pneumatic systems, reduce oil or air
pressure.
