Maintenance and Care

When reinstalling the wheels, ensure correct seating
of the valve stem. It must lock into the grooves of the
wheel hub.

tightening torque. Check the tyre pressure.
NOTE

into their correct location while
driving under load.
It is therefore essential to
retighten the wheel bolts/nuts
with the prescribed torque val-
ues after 50 operation hours on
new machines and every wheel change.
