Maintenance - PRONAR PT512 Operator's Manual

CHAPTER 2
• 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.
• Avoid potholes, sudden maneuvers or high speeds when turning.
• Check the tire pressure regularly. 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.

Center authorized by the manufacturer. After the expiry of the warranty period it is
recommended that repairs to the trailer are performed by specialized workshops.
• In the event of any fault or damage, do not use the trailer until the fault is fixed.
