Pronar T900 SECTION 5

TIP
Wheel nuts should be tightened using the torque of 450 Nm - M22x1.5 nuts.
ATTENTION
Wheel nuts may not be tightened with impact wrench because of danger of exceeding
permissible tightening torque, the consequence of which may be breaking the thread
connection or breaking off the hub pin.
The greatest precision is achieved using a torque spanner. Before commencing work,
ensure that correct tightening torque value is set.
ATTENTION
Checking the wheel nut tightening:
•
after first use,
•
after first travel with load,
•
after travelling the first 1,000 km,
•
every six months of use or every 25,000 km.
In the event of intensive work the wheel nut tightening should be checked at least every
10 000 km. The above actions should be repeated individually if a wheel has been
removed from the wheel axle.
5.2.5 CHECKING AIR PRESSURE IN TYRES, EVALUATING TECHNICAL
CONDITION OF TYRES AND STEEL WHEELS
Air pressure in tyres should be checked each time after changing a spare wheel and at least
once a month. In the event of intensive use, air pressure in tyres should be checked more
frequently. During this time, the trailer must be unloaded. Checking should be done before
travelling when tyres are not heated, or after an extended period of parking.
TIP
Tyre pressure values are specified in information decal, placed on wheel or on upper
frame above trailer wheel.
