GENERAL INFORMATION
GENERAL SAFETY INSTRUCTIONS
Specific warnings and cautions to inform about potential damages to people and machine are shown below.
DANGER!
–
–
This machine must be used by properly trained and authorised personnel only.
Moreover, the operator must:
•
•
•
•
Be of full age
Have a driving license
Be in normal psycho-physical conditions
Not be under the effect of substances that alters the nervous system (alcohol, psycopharmaceuticals,
drugs, etc.)
–
Before performing any maintenance/repair procedure remove the ignition key, engage the parking brake
and disconnect the battery.
Do not wear jewels when working near electrical components.
–
–
–
–
–
–
–
–
–
–
–
Do not work under the lifted machine without supporting it with safety stands.
When working under open hoods/lids, make sure that they cannot be closed by accident.
When performing maintenance procedures with the lifted hopper, apply the relevant support rods.
Do not operate the machine near toxic, dangerous, flammable and/or explosive powders, liquids or vapors.
Be careful, fuel is highly flammable.
Do not smoke or bring naked flames in the area where the machine is refuelled or where the fuel is stored.
Refuel outdoors or in a well-ventilated area, with the engine off.
Do not fill the fuel tank to the top, but leave at least 4 cm from the filler neck to allow the fuel to expand.
After refuelling, check that the filler cap is tightly closed.
If any fuel is spilled while refuelling, clean up the affected area and allow the vapors to dissipate before
starting the engine.
–
–
–
Avoid contact with skin and do not breathe in fuel vapors. Keep out of reach of children.
Do not tilt the engine too much to avoid fuel spillage.
During machine transportation, the fuel tank must not be full.
WARNING!
Carbon monoxide (CO) can cause brain damage or death.
The internal combustion engine of this machine can emit carbon monoxide.
Do not inhale exhaust gas fumes.
Only use indoors when adequate ventilation is provided, and when an assistant has been instructed to look
after you.
–
–
Do not lay any object on the engine.
Before working on the engine turn it off. To prevent the engine from starting accidentally, disconnect the
battery negative terminal.

GENERAL INFORMATION
WARNING!
–
–
Carefully read all the instructions before performing any maintenance/repair procedure.
Take all necessary precautions to prevent hair, jewels and loose clothes from being caught by the machine
moving parts.
–
Protect body parts (eyes, hair, hands, etc.) properly, when performing cleaning procedures using
compressed air or water gun.
–
–
–
–
–
–
–
Avoid contact with battery acid, do not touch hot parts.
Do not leave the machine unattended with the ignition key inserted and the parking brake deactivated.
Do not remove or modify the plates affixed to the machine.
To drive on public roads, the machine must follow local licensing requirements.
The machine has been designed to be used as a sweeper, do not use it for different purposes.
In case of part replacement, order ORIGINAL spare parts from an authorised Dealer or Retailer.
The machine must be disposed of properly, because of the presence of toxic-harmful materials (batteries,
etc.), which are subject to standards that require disposal in special centres (see the Scrapping chapter).
While the engine is running the silencer heats up. Do not touch the silencer to avoid serious scalding or
fire.
–
–
Do not run the engine if the oil level is low, to avoid damaging it seriously. Check the oil level with the
engine off and the machine on a level surface.
–
–
Do not run the engine if the air filter is not installed, to avoid damaging it.
The coolant line is pressurised; do not perform any check until the engine has cooled down and, even if the
engine is cold, the tank plug must be opened with extreme care.
–
–
Only use original spare parts or parts of matching quality for the diesel engine. Using spare parts of lower
quality can seriously damage the engine.
See also the SAFETY RULES in the Diesel Engine Manual, which is to be considered an integral part of this
Manual.
