electrical load on the circuit, wait a few minutes and then
reset the AC circuit breaker or AC circuit protector.
DC Operation
The DC terminals are used only for charging 12-volt
automotive type batteries.
Connecting the battery charging cables:
1. Before connecting the battery charging cables to a
battery that is installed in a vehicle, disconnect the
vehicle ground battery cable from the negative (-)
terminal of the battery.
WARNING:
The battery gives off explosive gases. Keep sparks,
flames, and cigarettes away. Provide adequate
ventilation when charging or using batteries.
WARNING: Lead and lead components are used in
battery posts, terminals, and related accessories. Always
wash hands after handling.
2. Connect the positive (+) battery cable to the positive
(+) terminal of the battery.
3. Connect the other end of the positive (+) battery cable
to the positive (+) terminal of the generator.
4. Connect the negative (-) battery cable to the negative
(-) terminal of the battery.
5. Connect the other end of the negative (-) battery cable
to the negative (-) terminal of the generator.
6. Start the generator.
NOTICE:
Do not start the vehicle while the battery charging cable is
connected and the generator is running. Doing so may
damage the vehicle or the generator.
The DC circuit protector will be tripped (the "PUSH" button
will extend out), if the DC circuit is overloaded, excessive
current is drawn by the battery, or a wiring problem
occurs. If this happens, wait a few minutes before pushing
in the circuit protector to resume operation. If the DC
circuit protector continues to go off, discontinue charging
and consult your authorized Makita generator dealer.
Disconnecting the battery cables:
1. Stop the engine.
2. Disconnect the negative (-) battery cable from the
negative (-) terminal of the generator.
3. Disconnect the other end of the negative (-) battery
cable from the negative (-) terminal of the battery.
4. Disconnect the positive (+) battery cable from the
positive (+) terminal of the generator.
5. Disconnect the other end of the positive (+) battery
cable from the positive (+) terminal of the battery.
6. Reconnect the vehicle ground battery cable to the
negative (-) terminal of the battery.
High Altitude Operation
At high altitudes, the standard carburetor air-fuel mixture
will be too rich, and will cause performance to decrease
and fuel consumption to increase. A very rich mixture will
also foul the spark plug and cause hard starting.
Operation for extended periods of time at an altitude that
differs from the altitude at which this engine was certified
may increase emissions.
Engine horsepower decreases about 3.5% for every
1,000-foot (300-meter) increase in altitude, even with
carburetor modification. If no carburetor modification is
10
made in the carburetor, the effect of altitude on
horsepower will be even greater. High altitude
performance can be improved by making specific
modifications to the carburetor. If the generator is to
always be operated at altitudes above 5,000 feet (1,500
meters), have your dealer perform this carburetor
modification. This engine, when operated at high altitudes
with the carburetor modifications for high altitude use, will
meet the various emission standards throughout its useful
life.
NOTICE:
When the carburetor has been modified for high altitude
operation, the air-fuel mixture will be too lean for use at
low altitudes. Operation at altitudes below 5,000 feet
(1,500 meters) with a modified carburetor may cause the
engine to overheat and result in serious engine damage.
For low altitude use, have your servicing dealer return the
carburetor to the original factory specifications.

PRE-OPERATION CHECKS

Check Engine Oil (Fig. 13)
Check the oil level before each use with the engine
stopped and the generator on a stable and level surface.
Use 4-stroke motor oil that meets or exceeds the
requirements for API Service Category SJ or later (or
equivalent). Always check the API SERVICE label on the
oil container to be sure the letters SJ or later (or
equivalent) are indicated.
1. Remove the oil filler cap/dipstick and wipe the dipstick
clean.
2. Insert the dipstick into the filler neck and check the oil
level. Do not screw in the filler cap.
3. If the oil level is low, fill to the upper limit of the oil filler
neck with the recommended oil.
Check Engine Fuel (Fig. 14)
With the engine stopped, check the fuel level gauge. Refill
the fuel tank if the fuel level is low.
WARNING:
Gasoline is highly flammable and explosive.
Burns or severe personal injury may result from
handling fuel.
• Stop the engine and keep heat, sparks, and flames
away.
• Refuel only outdoors.
• Wipe up spills immediately.
Refuel in a well-ventilated area with the engine stopped.
Allow the engine to cool first if it has been running. Refuel
carefully to avoid spilling fuel. Do not fill above the upper
limit mark.
Never refuel the engine inside a building where gasoline
fumes may reach flames or sparks. Keep gasoline away
from appliance pilot lights, barbecues, electric appliances,
power tools, etc.
Spilled fuel is a fire hazard and causes environmental
damage. Be sure to wipe up spills immediately.
NOTICE:
Be careful not to spill fuel when filling the fuel tank as fuel
can damage paint and plastic. Damage caused by spilled
fuel is not covered by the warranty.
After refueling, reinstall the fuel tank cap firmly.
