IMPORTANT
Axle 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 pins.
The greatest precision is achieved using a torque spanner. Before commencing work,
ensure that correct tightening torque value is set.
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 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.
DANGER
Damaged tyres or wheels may be the cause of a serious accident.
