3.6 SAFETY SYSTEMS
The machine is equipped with the following safety systems:
Emergency stop button:
A red emergency stop button is provided on the machine control panel.
Before using the machine, the operator should become familiar with its safety devices, to be able to
automatically actuate them in an emergency. The safety devices should never be reset before
having corrected the cause of an observed problem; contact a skilled technician if necessary.
Presence-sensing device:
The machine is equipped with a presence sensor integrated in the seat.
Without an operator on board, the machine will not start, and if the operator gets off the scrubbing
machine without having first turned the key switch to its 0 position, the machine will shut down. To
re-activate it, the operator must sit in the driving seat, turn the key switch to its OFF position, wait a
few seconds and then return the key switch to its ON position.
Float:
The recovery tank is equipped with a float which prevents suction in case of overfilling; in this
case, to restart the machine the tank must be emptied first (see the
WATER DRAINING
section
).
Solenoid valve:
The machine is equipped with a solenoid valve to let scrubbing water through only
after the brushes have been powered on, so as to prevent accidental leaking.
Float timer:
The machine is equipped with a timer on the waste water float to stop suction motor
power on and power off due to wave-like water motion.
