Technical inspection schedule
5.4 MEASUREMENT OF AIR PRESSURE, CHECK TIRES AND
WHEELS
During pressure measurement the trailer
must be unloaded. The inspection should
be carried out before driving, when the
tires are not warmed up or after a long
stop of the trailer.
ADVICE
In the event of intensive use of the trailer, we recom-
mend more frequent pressure checks.
The tire pressure value is on the information sticker
on the wheel rim - figure (5.2).
THE SCOPE OF ACTIVITIES
• Connect a pressure gauge to the
valve and check the air pressure. If
necessary, inflate the wheel to the re-
quired pressure.
• Check the technical condition of the
tires (tread depth, side wall of the
tire).
• Inspect the tire for defects, cuts,
deformations, bumps indicating me-
chanical damage to the tire. In the
event of mechanical damage, consult
your nearest tire service centre and
ensure that your tire defect is eligible
DANGER
Damaged tires or wheels can be the cause of a se-
rious accident.

CAUTION
Incorrect tire pressure can lead to permanent tire
damage as a result of delamination of the material
and also causes faster tire wear.
for replacement.
• Check that the tire is correctly posi-
tioned on the rim.
• Check tire age.
When checking the pressure pay attention
to the technical condition of the rims. Rims
should be checked for deformation, ma-
terial cracks, weld cracks, corrosion, es-
pecially around welds and in the place
contact with the tire.
