Principles Of Tires Use - PRONAR T400 Operator's Manual

Pronar T400
When disconnecting pneumatic system lines, first disconnect the cable with
the red connector, and then the cable with the yellow connector.
ATTENTION
The trailer disconnected from the tractor should be immobilized by means of the parking
brake, chocks should be placed under the wheel of the rigid axle.

4.8 PRINCIPLES OF TIRES USE

• When working with tires, secure the trailer against rolling away by placing chocks
or other elements without sharp edges under the wheels. The wheel can be
dismantled only when the trailer is not loaded.
• Repair work on wheels or tires should be carried out by persons trained and
authorized to do so. These works should be carried out using appropriately
selected tools.
• Regularly check and maintain proper tire pressure as recommended in the
instructions (especially after a long break of not using the trailer).
• 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 the pressure by venting if it increases due to temperature rise.
• Tire valves must be protected with suitable caps to avoid their dirtiness.
• Do not exceed the maximum design speed of the trailer.
• Avoid damaged road surfaces, sudden and variable maneuvers, and high speeds
when turning.
• Obey the 30 minutes breaks for cooling the tires after driving 75 km or after 150
minutes of continuous drive depending on what happens first.
• Checking the nut tightness should be carried out after the first use of the trailer,
after the first ride with a load and then every 6 months of use, or every 25,000 km.
