Exhaust fumes are poisonous
9 Using a generator indoors CAN KILL YOU IN
MINUTES. Generator exhaust contains carbon
monoxide. This is a poison you cannot see or
smell.
9 NEVER use inside a home or garage, EVEN IF
doors and windows are open.
9 Only use OUTSIDE and far away from windows,
doors, and vents.

Engine and muffler may be hot
9 Place the generator in a place where pedestrians
or children are not likely to touch the generator.
AE00075
Fuel is highly flammable and poisonous
9 Always turn off the engine when refuelling.
9 Never refuel while smoking or in the vicinity of an
open flame.
9 Take care not to spill any fuel on the engine or
muffler when refuelling.
9 Do not leave the generator inside the vehicle or in
the trunk.
9 If you swallow any fuel, inhale fuel vapor, or allow
any to get in your eye(s), see your doctor immedi-
ately. If any fuel spills on your skin or clothing,
immediately wash with soap and water and
change your clothes.
9 When operating or transporting the generator, be
sure it is kept upright. If it tilts, fuel may leak from
the carburetor or fuel tank.

9 Connect the Ground (earth) terminal to a ground
source. In order to prevent electrical shock, the
generator must be grounded when using an elec-
trical device with a ground plug.

Connection
WARNING
Before the generator can be connected to a build-
ing’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the build-
ing’s main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power
supply has failed or has been turned off for line
repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and build-
ing electrical system damage can occur when nor-
mal operating power returns if unit is used without
an isolation switch.
AE00086
Extension cord notes
Extension cords should be protected by a tough flexi-
ble rubber sheath (IEC 245) or the equivalent to with-
stand mechanical stresses.

Read the owner’s manual and all labels before operating.
Only operate in well-ventilated areas. Exhaust gas contains poisonous carbon monoxide.
Check for spilled fuel or fuel leaks.
Stop engine before refueling.
Do not operate near flammable materials.
Electrocution can occur if generator is used in rain, snow, or near water. Keep this unit dry at all times.
Electrocution or property damage can occur: Do not connect this generator to any building’s electrical
system unless an isolation switch has been installed by a licensed electrician. Refer to the owner’s manual.
When operating the generator:
Never place a partition or other barrier around the generator.
Do not cover the generator with a box.
Do not place any objects on the generator. 7CF-24162-50

Oil warning light (red)
When the oil level falls below the lower level, the oil
warning light (red) comes on and then the engine
stops automatically. Unless you refill with oil, the
engine will not start again.
TIP
If the engine stalls or does not start, turn the engine
switch to “7” (ON) and then pull the recoil starter. If
the oil warning light flickers for a few seconds, the
engine oil is insufficient. Add oil and restart.
DC protector
The DC protector turns to “ 3” (OFF) automatically
when electric device being connected to the generator
is operating and current above the rated flows. To use
this equipment again, turn on the DC protector by
pressing its button to “ I” (ON).
1 “ I” (ON)
Direct current is output. (This is the default position.)
2 “ 3” (OFF)
Direct current is not output.
NOTICE
Reduce the load of the connected electric device
below the specified rated output of the generator
if the DC protector turns off. If the DC protector
turns off again, stop using the device immediately
and consult a Yamaha dealer.

Fuel
WARNING
9 Fuel is highly flammable and poisonous.
Check “SAFETY INFORMATION” (See page 2)
carefully before filling.
9 Do not overfill the fuel tank, otherwise it may
overflow when the fuel warms up and expands.
9 After fill the fuel, make sure the fuel tank cap
is tightened securely.
1. Stop the engine.
2. Place the generator on a level surface.
3. Remove the fuel tank cap.
4. Check the fuel level.
5. If low, fill the tank with fuel.
NOTICE
9 Immediately wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may deteriorate
painted surfaces or plastic parts.
9 Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts.
Make sure there is sufficient fuel in the tank.
When refueling, be sure to fill the tank to the bottom
edge of the fuel tank filter.
