Using Underrun Protection Devices - PRONAR T386 Operator's Manual

Pronar T386
• Regularly check and maintain correct air pressure in tyres according to Operator's
Manual (especially if trailer is not used for a longer period).
• Air pressure in tyres should be also checked during the whole day of intensive
work. Please note that higher temperatures could raise tyre pressure by as much
as 1 bar. At high temperatures and pressure, reduce load or speed.
• Do not release air from warm tyres to adjust the pressure or the tyres will be
underinflated when temperatures return to normal.
• Protect tyre valves using suitable caps to avoid soiling.
• Do not exceed the trailer's maximum design speed.
• When the trailer is operated all day, stop working for a minimum of one hour in
the afternoon.
• Adhere to 30 minutes rest for cooling tyres after driving 75 km or after 150
minutes continuous travel depending on which occurs first.
• Avoid potholes, sudden manoeuvres or high speeds when turning.

4.11 USING UNDERRUN PROTECTION DEVICES

Side under run protection devices can be installed as additional equipment of the trailer. The
under run protection devices fulfil a very important role in road safety and therefore their good
technical condition should be ensured.
The under run protection devices are mounted to proper brackets (2) of the lower frame, by
means of bolts and nuts. The design of the side under run protection devices enables their
locking in the transport position and in the raised position.
DANGER
Under run protection devices must not be used as supporting elements while climbing
on the trailer.
Do NOT move off or drive when under run protection device is raised. Before driving,
make sure that under run protection devices are lowered and locked in the lower
position.
Unless necessary, do not leave the under run protection device in the raised position.
