Operating The Under Run Protective Device - PRONAR PT512 Operator's Manual

Pronar PT512
• Check the tightening of the nuts after first operation of the trailer, after the first
driving with load and then once per 6 months of operation or 25,000 kilometers. In
the event of intensive work checking the nut tightening should be done at least
every 100 km. The inspection should be repeated if a wheel has been removed
from the axle.
• Regularly check and maintain correct pressure in tires according to Operator's
Manual (especially if trailer is not used for a longer period).
• The air pressure should be also checked after the whole day of intensive work.
Please note that higher temperatures could raise tire pressure by as much as 1
bar. In case of such temperature and pressure rise, reduce the load or speed.
• Do not release air from tires to adjust the pressure.
• Protect tire 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 noon.
• To cool down the tires, stop for 30 minutes each time after driving 75 km or after
150 minutes of continuous travel depending on which occurs first.
• Avoid potholes, sudden maneuvers or high speeds when turning.

4.8 OPERATING THE UNDER RUN PROTECTIVE DEVICE

The trailer can be optionally equipped with two pairs of under run protective devices; both
devices can be tilted. Because these devices play an important role in road traffic safety,
ensure they are complete and in good condition.
