levers should be pushed forward until
they reach their limit stops (Fig. 36).

should be pulled backwards until they
reach their limit stops (Fig. 37).
3.3.6.7 Changing or replacing
driving wheels
After a change of driving wheels, checks
should be made to ensure that the
brakes are functioning correctly. The

or from PU tyres to another type of tyre,
the toggle joint brakes must be changed
at the same time.
