•
Inspect tightness of nuts before the first use of trailer, after the first travel under
load and then every 6 months of use or every 25,000 km. In the event of intensive
work, check the nut tightening at least every 100 km. The inspection should be
repeated individually if a wheel has been removed from the wheel axle.
•
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.
•
Take a 30 minute-break for cooling tyres after driving 75 km or after 150 minutes
of continuous travel, depending on which occurs first.
•
Avoid potholes, sudden manoeuvres or high speeds when turning.
4.8 USING UNDERRUN PROTECTION DEVICES
Two pairs of hinged tiltable under-run protective devices can be installed as trailer additional
equipment. The under-run protective devices fulfil a very important role in road safety and
therefore their good technical condition should be ensured.
Lifting
•
Pull the under-run protection device by holding its lower bar.
•
Raise the under-run protective device to the height shown in Figure (4.7)
•
Move the underrun protection device away. Appropriate recess and slotted
holes allow the locking of under-run protective device in the raised position.
