AIR INDEX
To show compliance with California emission regulations, a hangtag has been
provided displaying the Air Index level and durability period of this engine.
The Air Index level defines how clean an engine’s exhaust is over a period of
time. A bar graph scaled from “0” (most clean) to “10” (least clean) is used to
show an engine’s Air Index level. A lower Air Index level represents cleaner
exhaust from an engine.
The period of time (in hours) that the Air Index level is measured is known as
the durability period. Depending on the size of the engine, a selection of time
periods can be used to measure the Air Index level (see below).

1. SAFETY PRECAUTIONS
Do not operate the generator near gasoline or gaseous fuel because of the
potential danger 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 let dry before starting the engine.
Do not place in flammables near the generator.
Be careful not to place fuel, matches, gunpowder, oily cloths, straw, trash, or
any other in flammables near the generator.
Do not operate the generator inside a room, cave, tunnel, or other insufficient-
ly ventilated area. Always operate it in a well-ventilated area, otherwise the
engine may become overheated, and the poisonous carbon monoxide gas
contained in the exhaust gases will endanger human lives. Keep the,genera-
tor at least 1 meter (3 feet) away from any structure or building during use.
If the generator must be used indoors, the area must be well-ventilated and
extreme caution must be taken regarding the discharge of exhaust gases.
Do not enclose the generator nor cover it with a box.
The generator has a built-in forced air cooling system, and may become over-
heated 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 during generator use.
Operate the generator on a level surface.
It is not necessary to prepare a special foundation for the generator.
However, the generator will vibrate on an irregular surface, so choose a level
place without surface irregularities.
If the generator is tilted or moved during operation, fuel may spill and / or the
generator may tip over, causing a hazardous situation.
Proper lubrication cannot be expected if the generator is operated on a steep
incline or slope. In such a case, piston seizure may occur even if the oil is
above the upper level.

Pay attention to the wiring or extension cords from the generator to the con-
nected device.
If the wire is under the generator or in contact with a vibrating part, it may
break and possibly cause a fire, generator burnout, or electric shock hazard.
Replace damaged or worn cords immediately.
Do not operate in rain, in wet or damp conditions, or with wet hands.
The operator may suffer severe electric shock if the generator is wet due to
rain or snow.
If wet, wipe and dry it well before starting. Do not pour water directly over the
generator, nor wash it with water.
Be extremely careful that all necessary electrical grounding procedures are
followed during each and every use. Failure to do so can be fatal.
Do not 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. Use the transfer switch for connecting to domestic cir-
cuit.
No smoking while handling the battery. The battery emits flammable hydrogen
gas, which can explode if exposed to electric arcing or open flame.
Keep the area well-ventilated and keep open flames/sparks away when han-
dling the battery.
Engine becomes extremely hot during and for some time after operation.
Keep combustible materials well away from generator area.
Be very careful not to touch any parts of the hot engine especially the muffler
area or serious burns may result.
Keep children and all bystanders at a safe distance from work areas.

6. WATTAGE INFORMATION
Some appliances need a "surge" of energy when starting.
This means that the amount of electrical power needed to start the appliance may exceed
the amount needed to maintain its use.
Electrical appliances and tools normally come with a label indicating voltage, cycles / Hz,
amperage (amps) and electrical power needed to run the appliance or tool.
Check with your nearest dealer or service center with questions regarding power surge of
certain appliances or power tools.
■
Electrical loads such as incandescent lamps and hot plates require the same wattage
to start as is needed to maintain use.
■
Loads such as fluorescent lamps require 1.2 to 2 times the indicated wattage during
start-up.
■
Loads for mercury lamps require 2 to 3 times the indicated wattage during start-up.
■
Electrical motors require a large starting current. Power requirements depend on the
type of motor and its use. Once enough "surge" is attained to start the motor,
the appliance will require only 50% to 30% of the wattage to continue running.
■
Most electrical tools require 1.2 to 3 times their wattage for running under load during
use. For example, a 5,000 watt generator can power a 1800 to 4000 watt electrical
tool.
■
Loads such as submersible pumps and air compressors require a very large force to
start. They need 3 to 5 times the normal running wattage in order to start.
For example, a 5,000 watt generator would only be able to drive a 1,000 to 1,700 watt
pump.
NOTE :
The following wattage chart is general guide only. Refer to your specific appliance for cor-
rect wattage.
To determine the total wattage required to run a particular electrical appliance or tool, mul-
tiply the voltage figure of the appliance/tool by the amperage (amps) figure of same. The
voltage and amperage (amps) information can be found on a name plate which is normally
attached to electrical appliances and tools.

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS
When a long electric extension cord is used to connect an appliance or tool to the
generator, a certain amount of voltage drop or loss occurs in the extension cord
which reduces the effective voltage available for the appliance or tool.
The use of improper size or gauge of extension cords may cause unsafe or ineffi-
cient operation of your tool or appliance. It may also damage the tool or appliance.
Be sure that any extension cord that you use is rated to allow sufficient current flow
to the motor or appliance. Select the required wire gauge size according to the
chart below. Chart lists the minimum wire gauge size for the proper extension cord.
EXTENSION CORD CHART
Use the right extension cord. An extension cord should have a suitable wire size
for the overall cord length and tool amperage rating. This is to prevent a serious
voltage drop, power loss and possible motor damage. Generally, heavier gauge
wire is required as cord length increases. Use the recommendations in this table.

11. TROUBLESHOOTING
When generator engine fails to start after several attempts, or if no electricity is
available at the output socket, check the following chart. If your generator still fails
to start or generate electricity, contact your nearest Makita factory or authorized
service center for further information or corrective procedures.
When Engine Fails to Start :
Set the choke lever to "CLOSE" posi-
tion.
Check if choke lever is in its proper
position.
Check if fuel cock is open.
Check fuel level.
If closed, open fuel cock.
If empty, refill fuel tank making sure not
to overfill.
Check if engine switch is in OFF.
Turn engine switch to ON.
Check to make sure generator is not
connected to an appliance.
If connected, turn off the power switch
on the connected appliance and unplug.
Check spark plug for loose spark plug
cap.
If loose, push spark plug cap back into
place.
Check spark plug for contamination.
Remove spark plug and clean electrode.
When No Electricity Is Generated at Receptacle :
After making sure that the total wattage
of the electrical appliance is within per-
missible limits and there are no defects
in the appliance, turn the no-fuse break-
er to the "ON" position.
Check to make sure no-fuse breaker is
in the "ON" position.
If breakers continue to actuate, consult
your nearest servicing dealer.
Check AC and DC terminals for loose
connection.
Secure connection if necessary.
Turn off switch on the appliance, and
disconnect cable from receptacle.
Reconnect after generator has been
started properly.

attempted with appliances already con-
nected to generator.
