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.
5.2.7 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
pressure values are specified in information decal, placed on wheel or on upper frame
above trailer wheel.
DANGER
Damaged tyres or wheels may be the cause of a serious accident.
While checking pressure pay attention to technical condition of wheels and tyres. Look
carefully at tyre sides and check the condition of tread.
In case of mechanical damage consult the nearest tyre service and check whether the tyre
defect requires tyre replacement.
TIP
valve extension facilitates checking air pressure in internal wheel tyre.
Wheels should be inspected with regard to distortion, breaking of material, breaking of welds,
corrosion, especially in the area of welds and contact with tyre.
