6. SAFETY CONDITIONS
6.1 SAFETY DEVICES
Machine has been equipped with the following safety devices:
1. load-limiting device with automatically stop of the endothermic engine once the max. pre-set load
value has been exceeded
2. mechanical negative safety brake for movement stop in case of lack of hydraulic pressure
3. timing case and protections on moving parts, where technologically possible.
DANGER: it is absolutely forbidden the use of the machine without protecting timing
cases or with damaged/disconnected safety devices.
ATTENTION: after a serious emergency use of the negative safety brake, check the wear
condition of the discs and the efficiency of the brake itself; if necessary, replace the brake
discs before re-using the machine.
6.2 EMERGENCY STOP DEVICE
The specific mushroom push button for emergency stop that directly intervenes on the endothermic
engine carries out the emergency stop function (table 1, pos. 41).
The power generator locking causes the intervention of the vacuum brakes and, consequently, the
complete machine stop.
ATTENTION: use the emergency stop device ONLY in danger situations for the operators'
safety.
It is FORBIDDEN to use this device for the normal stopping of machine working activities.
6.3 PERIODIC OPERATIONS
Daily, before starting the work, the operator has to verify the functionality of the machine safety and
protecting devices.
ATTENTION: do not modify for any reason safety devices of the machine because the
manufacturer declines any responsibility as consequence of the non-functioning of the same.
6.4 RESIDUAL RISKS
During the machine use there are still the following residual risks:
1. Sudden break of the rope-conductor. The break of the rope or of the conductor causes sudden
movements of the machine and a whip effect of the rope or conductor section connected to the
machine.
To reduce to min. the risks the operator has to:

check the rope and replace it as soon as appear some defects or wear signs

respect the working positions indicated in the manual.
2. Sudden break of the anchoring stakes. The sudden break of the anchoring stakes causes the
machine instability and sudden movements of the same.
To reduce to min. the risks the operator has to:

periodically check the anchoring stakes and replace them as soon as appear some defects or
wear signs

follow the anchoring indications described in the present manual

respect the working positions indicated in the manual.
