1 SAFETY PRECAUTIONS
ADO not operate the generator near gasoline or gaseous fuel because of the
potentialdanger of explosion or fire.
Do not fill the fuel tank with fuel while the engine is running. Do not smoke or
use open flame near the fuel tank. Be careful not to spill fuel during refueling.
If fuel is spilt, wipe it off and letdry beforestartingthe engine.
A Do not placeinflammablesnearthe generator.
Be careful not to place fuel, matches, gunpowder, oily cloths, straw, trash, or
any other inflammablesnearthe generator.
ADO not operate the generator inside a room, cave, tunnel, or other insuffi-
ciently ventilated area. Always operate it in a well-ventilatedarea, otherwise
the engine may becomeoverheated, andthe poisonouscarbon monoxidegas
contained in the exhaust gases will endanger human lives. Keep the gener-
ator at least
1 meter (3 feet) awayfrom any structureor buildingduringuse.
If the generator must be used indoors, the area must be well-ventilatedand
extremecaution must betaken regardingthe dischargeof exhaustgases.
A Do notenclosethe generatornor cover itwith a box.
The generator has a built-in forced air cooling system, and may become
overheated if
it is enclosed. If generator has been covered to protect it from
the weather during non use, be sure to remove it and keep it well away from
the area duringgeneratoruse.
A Operatethe generatoron a levelsurface.
It is not necessaryto preparea specialfoundationfor the generator.However,
the generator will vibrate on an irregular surface,
so choose a level place
without surfaceirregularities.
If the generator is tilted or moved during operation, fuel may spill and/or the
generatormaytip over, causing a hazardoussituation.
Proper lubricationcannot be expected if the generatoris operated on
a steep
incline or slope. In such a case, piston seizure may occur even if the oil is
abovethe upper level.
APay attention to the wiring or extension cords from the generator to the
connecteddevice.
If the wire is under the generator or in contact with
a vibrating part, it may
breakand possiblycause a fire, generatorburnout,or electric shockhazard.
Replacedamagedor worn cords immediately.
A Do notoperatein rain, inwet or dampconditions,or with wet hands.
The operator may suffer severe electric shock if the generator is wet due to
rainor snow.
-1-

A If wet, wipe and dry it well beforestarting.
A Be extremely careful that all necessary electrical grounding procedures are
ADOnot contact the generator to a commercial power line. Connection to a
commercial power line may short circuit the generator and ruin it or cause
electric shock hazard.
Usethe transfer switchfor connectingto domestic circuit.
Do not pourwater directlyoverthe generator,norwash it with water.
followed duringeach and every use. Failureto do
so can befatal.
A No smokingwhile handlingthe battery.
The battery emits flammable hydrogen gas, which can explode
if exposed to
electric arcing or openflame.
Keep the area well-ventilated and keep open flames/sparks away when
handlingthe battery.
AEngine becomes extremely hot during and for some time after operation.
Keepcombustiblematerialswell awayfrom generatorarea.
Be very careful not to touch any partsof the hot engine especiallythe muffler
area or serious burnsmay result.
/i\Keep childrenand all bystandersat a safedistancefrom work areas.
AItis absolutely essentialthat you know the safe and proper use of the power
tool or appliancethat you intend to use.
All opetators must read, understand
and follow the tool/appliance owners manual. Tool and appliance and limita-
tions must be understood. Follow all directions given on labels and warnings.
Keepall instructionmanualsand literaturein a safe placefor future reference.
A Use only “LISTED” extensioncords.
When a tool or appliance is used outdoors, use only extensioncords marked
“For OutdoorUse”. Extensioncords,when not in use should be stored in a dry
andwellventilatedarea.
A Always switch off generator’s AC breaker and disconnecttools or appliances
when not in use, before servicing, adjusting, or installing accessories and

2. GROUNDINGTHE GENERATOR
To groundthe generatorto the earth,
connect the grounding lug of the gener-
ator to the grounding spike driven into
the earth or to the conductor which has
been already grounded to the earth.
If such grounding conductor or grounding
electorode is unavailable, connect the
grounding lug of the generator to the
grounding terminal of the using electric
tool or appliance.

NOTE :
The National Electrical Code (NEC) requires that all separately derived AC
systems be grounded per Article 250-26. Manufacturer has added a grounding
lugtype terminal per Article250-26(a)from the noncurrent-carrying metal parts
to the conductor to be grounded. Manufacturer does not supply the required
grounding conductor or grounding electrode because itwould be impossible to
cover every exception and all local code requirements. See your local dodes
and the NEC manualfor the proper grounding for your application.

PRECAUTIONS FOR USINGTHE GFCl RECEPTACLES
After starting the engine, check the GFCl for proper functioning by the following
test procedure.
Push TEST button. The RESET button will pop out exposing the word TRIP.
Power is now off at the outlets protected by the
GFCI, indicating that the
device isfunctioning properly.
H If TRIP does not appear when testing, do not use the generator. Call a
qualified electrician or have generator repaired at Makitafactory or authorized
service center.
To restore power, push RESETbutton.

If the RESET button pops out during operation,stop the generator imme-
diately and call a qualified electrician
to check generator and the
appliances. Failure to do
so may result in electric shock hazard or loss of
life.
(d) ChecktheAC breaker is “ON”.
If the breaker is “OFF, setthe breaker “ON”.
