CAUTION:
FOR YOUR OWN SAFETY
READ INSTRUCTION MANUAL
COMPLETELY AND
CAREFULLY BEFORE
OPERATING THIS GASOLINE
ENGINE Failure to follow all
instructions as listed below
may result in electrical shock,
fire, and/or serious personal
injury.
SPECIFICATIONS:
Engine: 2-stroke; Single Cylinder
Horizontal Shaf.
Start Type:Recoil Start
Rated Power: 800W
Fuel Capacity: 1.2 gallons
Run Time:5.5 hours
SAFETY WARNINGS
1) Do not operate this generator
indoors or in enclosed spaces.
Emissions created by this
generator are harmful.
2) Do not operate the generator in
wet conditions. This will increase
the risk of electrical shock.
3) Do not directly connect the
generator to a household power
supply.
4) Do not smoke while refueling
the generator. Do not overflow the
fuel when refueling the generator.
Stop the generator before
refueling. Gasoline is
flammable and the sparks may
cause it to ignite. Keep the
generator at least 3 feet away
from flammable materials.
5) Electrical equipment,
including any lines and plug
connections, should be
insulated.
6) The circuit breakers should
be matched with the generator
equipment. If the circuit
breakers need replacement,
they must be replaced with a
breaker that has identical
ratings and performance
characteristics.
7) Do not operate the generator
before grounding it. An
ungrounded generator could
cause electrical shock to occur.
8) The temperature of the
environment will affect the
overcurrent protector. Please
change the protector so it will fit
with the local environment
temperature.

OPERATING
INSTRUCTIONS
GROUNDING THE
GENERATOR
Connect a #10 AWG
groundingwire (not included) from
the generator grounding log on the
front of the generator to a
grounding rod (not included). The
grounding rod must be an earth-
driven copper or brass rod
(electrode) which can adequately
ground the generator.
(See Figure A).
PRE-START CHECKS:
1. Check to make sure the Engine
Power Switch is in its "OFF"
position. (See Figure C)
CAUTION! Your Warranty is VOID
if the Engine’s Fuel Tank is not
filled with the proper mixture (50:1)
of unleaded gasoline and 2-cycle
oil before each use. Before each
use, check the fuel level. Do not
run the Engine with an improper
unleaded gasoline/2-cycle oil
mixture. Running the Engine with
an improper mixture WILL
permanently damage the Engine.
2.The Fuel Tank holds
approximately 1 gallon of fuel.
3. To obtain the proper gasoline
and 2-cycle oil mixture, mix 2.5
fluid ounces of 2-cycle oil with 1
gallon of unleaded gasoline into
an approved container. Then
slowly shake the container to
thoroughly mix the gasoline/2-
cycle oil.(See Figure B.)
4.Remove the Fuel Tank Cap
and check the fuel level. (See
Figure C.)

4.Turn the Engine Choke Lever
to its "CHOKE" position. Set the
Choke Lever in the "RUN"
position when starting a warm
Engine. (See Figure E.)
5.Then turn the Engine Power
Switch to its "ON" position. (See
Figure F.)
6.Grasp the Recoil Starter
Handle and pull slowly until
resistance is felt. While holding
the Handle, allow the Starter
Rope to rewind slowly. Then, pull
the Starter Handle with a rapid,
full arm stroke. Once again while
holding the Handle, allow the
Rope to rewind slowly. Repeat as
necessary, until the Engine
starts. (See Figure G.) warm up
for five minutes after starting with
no electrical load.
5. After the Engine starts and
warms up, slowly move the
Choke Lever to its "RUN"
position. (See Figure H.)
IMPORTANT: Allow the Engine
to run at
6. no load until warm (approx. 3
minutes) after each start-up to
allow the Engine to stabilize.
EQUIPMENT OPERATION
1.The total combined load
through the outlet on the
Generator must not exceed the
rated maximum power of the
unit.
2.Always reduce the load if the
AC Circuit Breaker turns off.
Once the load is reduced, press
the Breaker to reset the
Generator and continue
operation. (See Figure I.)
3.Allow the Engine to run at no
load until warm (approx. 3
minutes) after each start-up to
allow the Engine to stabilize.
4.To fill the Fuel Tank, first wipe
off the Fuel Tank Cap and the
surrounding area. (See Figure
C.)
5.Unscrew, and remove the Fuel
Tank Cap (See Figure C.)
6.Remove the Strainer and
remove any dirt and debris.
Then replace the Strainer. (See
Figure C.)
7.Fill the Fuel Tank to about 1
inch under the fill neck of the
Tank with the pre-mixed
unleaded gasoline/2-cycle oil
mixture.
8.Then replace the Fuel Tank
Cap (See Figure C.)
TO START THE ENGINE
1.Check to make sure the
Engine Switch is in its "OFF"
position.
2.IMPORTANT:Make sure to
unplug any load from the
Generator before starting to any
appliance, tool, or equipment.
3.Turn the Engine Fuel Switch to
its "ON" position. (See Figure D.)

Figure K.)
2.Allow the Engine to run for
approximately 3 minutes with no
electrical load.3.Turn off the
Generator’s Power Switch to stop
the Engine.(See Figure L.)
4.Turn the Fuel Switch to its
"OFF" position. (See Figure M.)
5.Allow the Generator to
completely cool before
storing.with no electrical load.
MAINTENANCE
Many maintenance
procedures, including those
not detailed in this manual, will
need to be performed by a
qualified technician for safety.
If you have any doubts allow
the Engine to stabilize.about
your ability to safely service
the equipment or Engine, have
a qualified technician service
the equipment instead.
Air Filter Element Maintenance:
1.Wipe off the Air Cleaner Cover.
Then remove the Cover. (See
Figure N.)
2.Remove the Air Filter Element.
3.Wash the Air Filter Element in
warm water and mild detergent
several times. Rinse. Squeeze
out excess water and allow it to
dry completely. Soak the Filter in
lightweight oil briefly, then
squeeze out the excess oil.
4.Install the new Air Filter
Element or the cleaned Filter.
Secure the Air Cleaner Cover
before use.
4.Plug the power cord of the 120
volt appliance/tool into the 120
volt AC Outlet on the Generator.
(See Figure J.)
5.NOTE: Do not allow the
generator to completely run out
of fuel with devices attached. A
generator’s output may sharply
spike as it runs out of fuel,
causing damage to attached
devices.
6.When finished using the
appliance/tool, unplug its power
cord from the AC Outlet on the
Generator. (See Figure K.)
7.For DC current, plug into the
DC plug located on the side of
the generator. To charge your
car battery, connect the alligator
clips to the corresponding
terminals on your battery, The
red lead goes to the positive (+)
terminal and the black lead goes
to the negative (-) terminal. This

Spark Plug Maintenance:
1.Disconnect Spark Plug Wire
from end of plug. Clean out
debris from around Spark Plug.
2.Using the spark plug wrench
provided, remove the Spark
Plug.
3.Inspect the Spark Plug:If the
electrode is oily, clean it using a
clean, dry rag. If the electrode
has deposits on it, polish it using
emery paper. If the white
insulator is cracked or chipped,
the Spark Plug needs to be
replaced.
4.When installing a new Spark
Plug, adjust the Plug’s gap to the
specification on the Technical
specification chart and in the
FIGURE N
FIGURE O
illustration below. Do not pry
against the electrode or the
insulator, the Spark Plug can be
damaged. (See Figure O.)
5.Install the new Spark Plug or
the cleaned Spark Plug into the
Engine. Gasket-style: Finger-
tighten until the gasket contacts
the cylinder head, then about
1/2-2/3 turn more.
Non-gasket-style: Finger-tighten
until the plug contacts the head,
then about 1/16 turn more.
