2.4 Fire prevention
2.4.1 Fire due to fuel, oil
• Avoidapproachinganyametoammablesubstances
such as fuel and oil.
• Donotsmokeoruseopenamesnearammablesub-
stances.
• Stop the machine before refuelling.
• Makesurenottospillammablesubstancesonover-
heated surfaces or on parts of the electrical system.
• Afterrefuelling,removeanyspillsandtightenalllling
caps tightly.
• For safety in the workplace, store the cloths soaked in
ammablematerialsinacontainer.
• Store oil and fuel in pre-established and well-ventilated
locations and prohibit the entry of unauthorised person-
nel.
• Whencleaningthemachine,donotuseammablesub-
stances such as diesel or gasoline.
2.4.2 Fires caused by ammable material build-up
• Removedryleaves,chips,piecesofpaper,carbondust,orotherammablematerialsaccumulatedfrom
the machine.
2.4.3 Fire caused by electrical wiring
• Always keep the electrical wiring clean and tightened.
• Periodically check that there are no loose or damaged parts. Tighten loose wiring connectors or termi-
nals.
• Repair or replace any damaged cables.
2.4.4 Fire caused by piping
• Periodicallycheckthatthehoseclampsarermlyxed.
• Ifloosened,theymayvibrateduringmachineoperationandcauseleakageofliquids,provokingresand
serious injuries, including fatalities.
2.5 Lifting and transport precautions
2.5.1 Lifting and manual transport
• Handlethemachinewiththespecialhandle.
• Handlethemachinewiththeengineo󰀨,theelectricalcablesdisconnectedandthefueltankempty.
2.6 Precautions for positioning the machine
2.6.1 Positioning site precautions
• The machine may not be used indoors, such as in homes and garages, even if the doors and windows
are open.
This machine has been designed for outdoor use and can therefore be positioned outdoors.
In case of meteorological precipitation (rain, snow, etc.), place the machine in an adequately sheltered
place. If this is not possible, do not use the machine.
• Donotplacemachinesorequipmentnearheatsources,inareasatriskwithexplosionhazardorre

hazard.
Placethemachineatasafedistancefromfueltanks,fromammablematerial(rags,paper,etc.),from
chemicals.
Follow the instructions of the competent authorities.
• To limit potentially dangerous situations, isolate the area around the machine, thus preventing any unau-
thorized personnel from getting close to it.
• Although the machines produced comply with the regulations on electromagnetic compatibility, do not
placethemachinenearequipmentinuencedbythepresenceofmagneticelds.
• Make sure that the area immediately surrounding the machine is clean and free of debris.
• Alwaysplacethemachineonaat,solidsurfacethatisnotsubjecttofailureinordertoavoidtipping,
slipping or falling during operation.
• The machine must always be positioned so that exhaust
gases disperse into the air without being inhaled by
people or animals.
The exhaust gases of an engine contain carbon mon-
oxide:thissubstanceisharmfultohealthand,inhigh
concentration, can cause poisoning and death.
• If the machine is used indoors, make sure that the area
is well ventilated.
2.6.2 Precautions for electric connections
• Use appropriate electrical plugs at the machine output
sockets and make sure that the electrical cables are in
good condition.
• Do not use the machine with wet or damp hands and/or
clothing.
D5260150
D5260160
2.7 Precautions during operation
• Immediately stop the machine in case of malfunctions.
Donotrestartthemachinewithoutrstidentifyingandsolvingtheproblem.
• Do not wrap or cover the machine with cloths while it is running.
Before covering the machine, make sure that the engine parts are cold
Iftheenginepartsarestillwarm,thereisariskofdamagetothemachineandre.
• Do not place objects or obstacles near the air suction and expulsion windows; a possible overheating of
thegeneratorcouldcauseare.
2.8 Precautions against noise
• Excessive noise can cause temporary or permanent hearing problems.
The actual risk arising from the use of the machine depends on its use conditions.
• There is a decal on the machine that declares the sound power level dB(A) emitted by it. The value pro-
vides an indication of the noise level emitted by the machine when used, in order to assess the noise in
the environment where the generator is placed.
• Theadoptionofspecicmeasures(suchasheadphonesorearplugs)mustbeassessedbytheoperator.

2. Safety
2.9 Precautions during fuel and engine oil lling
• Fuelandengineoilareammable.
Rellwiththeengineo󰀨.
• Refuel only outdoors or in well-ventilated environments.
• Donotsmokeorusenakedamesduringrefuelling.
• Do not fuel with the engine running or hot.
• Clean and dry any leaks of engine oil and fuel before
restarting the machine.
• After refuelling, fully tighten the tank caps.
• Donotllthefueltankcompletelytoallowexpansionof
the fuel inside it.
• Do not exceed the MAXIMUM engine oil level.
2.10 Maintenance precautions
• Stop the machine and disconnect all electrical devices.
• To avoid injury, do not perform maintenance with the engine running.
◦Rotating parts, such as the fan, are dangerous and can get entangled on body parts or a worn object.
Whenperformingmaintenance,becarefultoapproachrotatingparts.
◦Make sure not to drop or insert tools or other objects in the fan or other rotating parts. They can touch
the rotating parts and be projected.
• Donottouchtheengine,pipesandmu󰀪erduringoper-
ationorimmediatelyaftershut-o󰀨.Allowtheengineto
cool before performing any operation.
• Whendischargingtheengineoil,theenginemustbehot.
Engine oil may come into contact with the skin and
cause burns.
• Do not remove the guards and safety devices.
If it is necessary to remove them, after completing the
maintenance, install the removed guards and restore the
safety devices.
• Use work tools in good condition and suitable for the
work to be performed.
If you use a damaged or deformed tool or if you use a
tool for a purpose other than its intended purpose, there
is a danger of causing serious personal injury or death.
• Be careful not to damage the electric starter battery, as it
contains lithium. .
If lithium leaks out and comes in contact with oxygen in
theair,itcancatchrecausinganexplosion.

2.11 Precautions for disposal of waste material
• Be sure to store the waste liquid in containers or tanks.
• Do not discharge the oil directly into the soil or sewage
system, rivers, seas or lakes.
• Whendisposingofharmfulwastesuchasoil,fuel,cool-
ant,solvents,ltersandbatteries,followcurrentlaws
and regulations.
• Entrust the authorized companies with the disposal of
rubber material, plastic and components that contain
them (hoses, cables, wiring, etc.) in accordance with the
applicable laws and regulations.
2.12 Disposal of the machine
ThismachineisclassiedasElectricalEquipment.
For disposal, comply with Directive 2012/19/EU on waste of
electricandelectronicequipment(WEEE).
Thesymbola󰀩xedtotheproductortothedocumentation
states that, at the end of its useful life, the machine must be
disposed of separately.
Adequate separate collection helps avoid possible negative
e󰀨ectsontheenvironmentandhealthandpromotesthe
reuse and/or recycling of the materials that make up the
equipment.
