tentional movement, both lateral brake
levers should be pushed forward until
they reach their limit stops (Fig. 36).

driving wheels
After a change of driving wheels, checks
should be made to ensure that the
brakes are functioning correctly. The
brakes should then be reset if necessary

special toggle joint brake.
When changing to a wheel with PU tyres,
or from PU tyres to another type of tyre,
the toggle joint brakes must be changed
at the same time.
