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 authorized personnel only.–Moreover, the operator must:–Be 18 years or older• 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 jewelry when working near electrical components.–Do not work under the lifted machine without supporting it with safety stands.–When working under open hoods/doors, make sure that they cannot be closed by accident.–When performing maintenance procedures with the lifted hopper, apply the relevant safety 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 refueled 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 1.6 in (4 cm) from the filler neck to allow the fuel to–expand.
After refueling, check that the filler cap is tightly closed.–If any fuel is spilled while refueling, 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 diesel engine turn it off. To prevent the engine from starting accidentally, disconnect–the battery negative terminal.

INFORMAZIONI GENERALI
WARNING!
Carefully read all the instructions before performing any maintenance/repair procedure.–Take all necessary precautions to prevent hair, jewelry 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 disengaged.–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 authorized 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 centers (see the Scrapping chapter in
the Instructions for use Manual).
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 pressurized; 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.

Risk of machine tip-over and serious injury
Sharp turns must be made at slowest possible speed.
Do not - Turn abruptly
- Turn on incline
- Turn with hopper raised
Never raise hopper on incline.
Operating on incline or with weight in the hopper increases instability.
Regularly check tires for appropriate air pressure according to Operator’s Manual.
