•
In the event of prolonged work stoppage, it is essential to lubricate all elements
regardless of the period of the last lubrication process.
•
Wheel rims and tyres should be carefully washed and dried. During longer
storage of unused trailer it is recommended that every 2 to 3 weeks the machine
may be moved a bit so that the place of contact of tyres with ground is changed.
The tyres will not be deformed and maintain proper geometry. Also tyre pressure
should be inspected from time to time, and if necessary pressure should be
increased to appropriate value.
5.11 TIGHTENING TORQUE FOR NUT AND BOLT
CONNECTIONS
Unless other tightening parameters are given, during maintenance repair work apply
appropriate torque to tighten nut and bolt connections. Recommended tightening torque
values for the most frequently used bolt and nut connections are given in table (5.8). Given
values apply to non-lubricated steel bolts.
