Main mechanisms
Mechanical parts in mutual rotation should be inspected periodically, checking the condition of nuts,
bolts and screws to make sure none have been loosened. Before each use, visually inspect the ixing
screws and nuts connecting the slewing ring to the chassis and turret, the gearbox, the connection
between the rotating joint and the turret, the locks on the pins, the ixing nuts on the vehicle, all other
bolts, particularly on parts subjected to vibration and movement. Before each use, also visually inspect
all the structural components for cracks in welds, corrosion or signs of wear. After the irst 100 hours
and then every 3 months or 500 hours, check:
•
the tightness of the turntable ixing nuts using a torque wrench (refer to the “Tightening torque”
table)
•
the tightness of all connecting bolts of the subframe to the truck using a torque wrench (refer
to the “Tightening torque” table)
