Safety information

Exhaust fumes are poisonous

• Using a generator indoors CAN KILL YOU IN MIN­UTES. Generator exhaust contains carbon monox­ide. This is a poison you cannot see or smell.

• NEVER use inside a home or garage, EVEN IF
doors and windows are open.

• Only use OUTSIDE and far away from windows,
doors, and vents.

Fuel is highly flammable and poison­ous

• Always turn off the engine when refuelling.

• Never refuel while smoking or in the vicinity of an
open flame.

• Take care not to spill any fuel on the engine or muf­fler when refueling.

• Do not leave the generator inside the vehicle or in the
trunk.

• If you swallow any fuel, inhale fuel vapor, or allow any
to get in your eye(s), see your doctor immediately. If
any fuel spills on your skin or clothing, immediately
wash with soap and water and change your clothes.

1-2

• When operating or transporting the generator, be
sure it is kept upright. If it tilts, fuel may leak from the
carburetor or fuel tank.

Safety information

Engine and muffler may be hot

• Place the generator in a place where pedestrians or
children are not likely to touch the machine.

• Avoid placing any flammable materials near the
exhaust outlet during operation.

• In order to prevent overheating, ensure adequate air­flow by keeping the machine at least 1 m (3 ft) from
objects or other equipment.

• Do not operate the engine with a dust cover or other
objects covering it.

• When covering the generator, be sure to do so only
after the engine and muffler have completely cooled
down.

Electric shock prevention

• Never operate the engine in rain or snow.

WARNING

• Never touch the generator with wet hands or electri­cal shock will occur.

• Connect the ground (earth) terminal to a ground

source. In order to prevent electrical shock, the gen
erator must be grounded when using an electrical
device with a ground plug.

Connection notes

• Avoid connecting the generator to commercial power
outlet.

• Avoid connecting the generator in parallel with any
other generator.

Connection

Before the generator can be connected to a build­ing’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the build­ing’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 build­ing electrical system damage can occur when nor­mal operating power returns if unit is used without
an isolation switch.

Extension cord notes

Extension cords should be protected by a tough flexible
rubber sheath (IEC 245) or the equivalent to withstand
mechanical stresses.
