Measurement Of Air Pressure, Check Tires And Wheels - PRONAR T672ECO User Manual

Periodic inspections of the trailer
5.8 MEASUREMENT OF AIR PRESSURE, CHECK TIRES AND
WHEELS
During pressure measurement the trailer
must be unloaded. Checking should be
carried out before driving, when the tires
are not warm, or after a long standstill of
the trailer.
THE SCOPE OF ACTIVITIES
• Connect a pressure gauge to the
valve.
• Check air pressure.
• If necessary, infl ate the wheel to the
required pressure.
The required air pressure is de-
scribed on a sticker (1) on the
rim.
• Check tread depth.
• Check the side wall of the tire.
• Inspect the tire for defects, cuts,
deformations, bumps indicating me-
chanical damage to the tire.
• Check that the tire is correctly posi-
tioned on the rim.
• Check tire age.
When checking pressure, pay attention to
the technical condition of rims and tires. In
the event of mechanical damage, consult
your nearest tire service centre and
Figure 5.6 Trailer wheel
(1) sticker (2) valve
ensure that your tire defect is eligible for
replacement. Rims should be checked for
deformation, material cracks, weld cracks,
corrosion, especially around welds and in
the place contact with the tire.
ADVICE
In the event of intensive use of the trailer, we recom-
mend more frequent pressure checks
CAUTION
Using the trailer in which tires are not properly inflat-
ed may lead to permanent damage to the tire as a
result of delamination of the material.
Incorrect tire pressure also causes faster tire wear.
