EMERGENCY STEERING
This machine is equipped with an emergency steering system
and complies to ISO 5010 (BSEN 12643). In the advent of failure
of the source of power for the steering system (engine failure)
whilst travelling, the machine can be steered allowing the
machine to be safely stopped.
In such a case, the effort required at the steering wheel and the
number of turns to steer the machine will increase. To confirm
function of emergency steering system, raise the front wheels off
the ground (using the work equipment) and with the engine off,
turn the steering wheel and check movement of the wheels.
EMERGENCY BRAKING
This machine is equipped with an emergency braking system and
complies to ISO 3450. In the advent of failure of the source of
power for the braking system (engine failure) whilst travelling, the
brakes can be actuated from stored energy in the accumulators to
bring the machine safely to a stop.
In such a case, seven brake applications can be made before
exhausting the energy in the accumulators. In the advent of ser-
vice brake failure, the park brake can be used as an emergency
brake to bring the machine to a stop.
